Ever since people first wandered the Earth, great significance has been given to the celestial objects seen in the sky. Throughout human history and across many different cultures, names and mythical stories have been attributed to the star patterns in the night sky, thus giving birth to what we know as constellations.

On 23 Feb. The video of this Duologue is available on this YouTube page. The intent of the publisher is to show that Nature is " fully committed to open research and the benefits this brings for researchers, institutions, funders and the wider public. Hybrid journals operate on a subscription basis, but provide researchers with the opportunity to make their individual articles OA for a fee. They emphsize their commitment to OA, but focus on the in their view continued need for hybrid journals i.

However, this very useful tool is only available for the Firefox and Chrome browsers. Follow this link to download the slides. We are happy to announce that as of today, Nathalia Escarlate will be joining the Library and Information Centre team in Garching. Nathalia is a trained librarian, documentalist, and data analyst, with experience in database administration and task automation.

We are very much looking forward to working with her! It is no exaggeration to say that an era ends. We cordially thank Maria Eugenia for everything she has done during all these years in La Silla and Santiago, and send her our very best wishes for the new phase in her life, along with un abrazo fuerte. Maria Eugenia, we will miss you! As of September, she will become the new Librarian in Chile. Leslie can be reached at Leslie. Saldias eso.

Please join us in welcoming Leslie to ESO!! The Dutch publisher Elsevier is looking into the possibility that some peer reviewers are encouraging the authors of work under review to cite the reviewrs' own research in exchange for positive reviews — a frowned-on practice broadly termed coercive citation.

Although a special focus was on biology, some of the overall trends are also valid for astronomy. Some are obvious anyway. Second, it is clear that citation number has become a target for some researchers. We observe a general increasing trend for researchers to cite their previous work in their new studies, with some authors self citing dozens, or even hundreds, of times.

Clearly, a signficant amount of resources is spent on papers with limited impact, which may indicate that researchers are publishing more papers of poorer quality to boost their total number of publications. Third, we observed an exponential growth in the number of new researchers who publish papers, likely due to career pressures. We also observed that young career researchers tend to publish considerably more than researchers in previous generations did at their career age. Fourth, certain trends are shaping the landscape of publishing in top journals.

The number of papers in selected top journals has increased sharply, along with the career age of the authors and the percentage of returning authors. The number of submissions to journals like Science has soared in recent years; however, many of these journals mainly publish papers in which at least one of the authors has previously published in the journal.

By comparing academic metrics over research fields and subfields, we observed vast diversity in the properties of papers in across different domains. Even papers within subdomains presented a wide range of properties, including number of references and median number of citations. But that provides only the coldest comfort.

If I regretted selling you a book, I didn't get to break into your house and steal it, even if I left you a cash refund for the price you paid". Open Access, subscriptions, transformative agreements…. The new interface, codenamed Bumblebee and under development since , has now reached parity with ADS Classic. The plan is to begin disabling searching in Classic in May , with full site retirement foreseen for Q3 For further information, see the ADS blog updated April 12, including suggestions to regular Classic users in order to prepare for the transition.

In addition, telbib also provides a set of predefined charts. Following requests from telbib users, additionally the underlying data tables of all charts are now available in the web browser, or as downloads in CSV or XLS format.

This new download option gives users more flexibility to process the data according to their needs. All telbib charts are interactive; the data exported in the CSV and XLS tables correspond to the selection made by the user. The first ebooks in the AAS-IOP Astronomy collection are now available: Astrophysics of Red Supergiants Emily Levesque This is the first book of its kind devoted to our current knowledge of red supergiant stars, a key evolutionary phase that is critical to our larger understanding of massive stars.

The book is accessible to a broad range of experience levels, from graduate students up to senior researchers, in fields ranging from stellar astrophysics to supernovae and high-redshift galaxies.

Understanding Stellar Evolution Henny J. It describes the structure and evolution of stars, with emphasis on the basic physical principles and the interplay between the different processes inside stars. An extensive set of accompanying lecture slides is available for teachers.

A selection of forthcoming titles can be found here. ORCID provides you with a unique author identifier that reliably and clearly connects you with your research contributions and affiliations. Questions that will be answered in this presentation include:. Members of ResearchGate, a commercial academic social network through which scientists share also copyrighted publications, may be interested in the following news: "The academic social network ResearchGate has taken moves to restrict access to at least 1.

The change, which follows months of conflict between the organizations, means that papers once freely available to download now have to be requested directly from their authors.

This guide will help researchers submit an article to IOP journals, and includes advice on what the publisher looks for in articles, and how to prepare files and manage revisions.

This is the fist large-scale analysis investigating the effect of open access books. A sample of Springer Nature OA books and 17, non-OA books was included in the download analysis using SpringerLink data , and OA books and 14, non-OA books in the citations and mentions analysis using data from Bookmetrix.

The report also contains qualitative analysis from authors and funders. Info from the reuters. CUP, the publishing arm of elite Cambridge University, later reversed its decision and reposted the articles, following an outcry from academics, who attacked the decision as an affront to academic freedom.

By connecting this iD to all their research activities, publications, and affiliations, researchers will be able to benefit from improved recognition, reduce reporting burdens, and ensure they receive full credit for their work.

In case you have any questions, email us at library eso. The paper by Piwowar et al. The study analysed reader data from the Unpaywall tool, a free and legal browser extension that finds open access versions of scholarly articles. The paper was also featured in a Nature News article.

Unpaywall is a browser add-on for Firefox or Chrome that will search for Open Access copies of articles across the Internet. Behind Unpaywall is Impactstory , a nonprofit website working to make science more open and reusable online. Sloan Foundation. The ESO Library has created the beta-version of a resolver for references in manuscripts.

Using references in. The use case we have in mind is the refereeing process: you receive a manuscript for review for which you would like to access the cited papers. Instead of searching for them manually in ADS, you upload the manuscript to the resolver and simply click on the provided links. If you would like to give it a try, please upload your. Please note that this platform is still experimental, so not all references will currently be resolved correctly.

We hope to improve the service based on your feedback: library eso. A recent paper posted on arXiv analyzes the role of the first author gender on the number of citations that a paper receives. The findings have been reported in a Nature News item on Nov. The next step is to link Writing Studio with all the EDP Sciences journals and their submission systems and integrate this tool in a comprehensive LaTeX dedicated workflow, from the writing of an article through to its online publication.

The journal "will be a multidisciplinary journal for the field, representing and fostering closer interaction between all of the key astronomy-relevant disciplines. Nature Astronomy will publish the most significant research, review and comment at the cutting edge of astronomy, astrophysics and planetary science. ORCID Open Researcher and Contributor ID provides a persistent digital identifier that distinguishes you from every other researcher and supports automated linkages between you and your professional activities, ensuring that your work is recognised and attributed to you.

It is not associated with any specific publisher, discipline, or geographic area. The use is free of charge. The library has created a short guide that explains how:. The Liberty APCs model means that authors can choose the level of article processing charge they will pay to publish their article.

In The amount can be as low as 0 EUR. It is expected that authors will investigate all options for funding e. Liberty APC is a useful model for journals at launch stage and for the first years of publication. According to the announcement distributed by the publisher of the AAS journals, IOP Publishing, the new website, curated by Susanna Kohler, provides "highlights of recently published articles from the AAS journals to inform astronomy researchers about breakthroughs and discoveries they might otherwise overlook.

The ESO library catalog has undergone a major software upgrade so that the system now uses responsive web design. While providing a similar look and feel as before, the enhanced user interface allows users to search the catalog on a wide range of devices, including smartphones and tablets. These books can be read online at any time. In case you are interested in other titles in electronic or print format, let us know as we can purchase specific books on request.

If you co- authored a paper, please send the SPIE manuscript number e. Some time ago we had to stop providing access to the Safari ebook platform as their license agreement was reviewed by the ESO legal department. Unfortunately, it turned out that Safari's lawyers were not able to accept specific changes to their license which are mandatory for any contract signed by ESO. Further discussion offered by ESO was rejected by Safari. As a result, we cannot provide access anymore.

We regret this development, but have no means to influence the legal situation. Should you be interested in programming and technical books in future, please send a request to library eso.

The Constellations

Our experiment was performed with a much more sensitive detection system, and with better spatial resolution, than on previous occasions and eclipses , allowing fine details of quiet coronal loops and an active-region loop system to be seen. The camera pixel size was 1. A total of images were recorded during a In the analysis, we searched particularly for short-period intensity oscillations and travelling waves, since theory predicts fast-mode magneto-hydrodynamic MHD waves with short periods may be important in quiet coronal and active-region heating. We also searched for travelling waves along some 65 coronal structures. However, we found no statistically significant evidence in either. This negative result considerably refines the limit that we obtained from our previous analyses, and it indicates that future searches for short-period coronal waves may be better directed towards Doppler shifts as well as intensity oscillations.

In the spring of , nearly broke, struggling with a novel and having exhausted the patience of everyone around me, I wrote a letter begging for some kind of job to every publisher listed in the Boston Yellow Pages. I had a physics degree from M. The company would never give me such an exorbitant salary on a full-time basis, he said.

This activity is related to a Teachable Moment from Aug. The "Pi in the Sky" math challenge gives students a chance to take part in recent discoveries and upcoming celestial events, all while using math and pi just like NASA scientists and engineers.

Press Releases

To help you learn about the southern night sky, Sydney Observatory provides an audio guide, transcript of that audio, and a sky map or chart each month. Mel suggests stars and constellations to look out for this month include Scorpius, with the red star at its heart, Antares; Sagittarius which looks more like a teapot than a centaur ; Crux — more commonly known as the Southern Cross; and Ophiuchus, the 13th sign of the zodiac! Mel also tells us the best times and dates to see the planets Venus, Saturn, Jupiter and Mercury.

Наконец-то, черт возьми. Бринкерхофф поднял трубку: - Канцелярия директора. Фонтейн протянул руку. Бринкерхофф со смущенным видом повернулся к Мидж: - Это Джабба. Он хочет поговорить с .

Фонтейн стоял, тяжело дыша. - У нас нет причин ему не верить.  - Это прозвучало как сигнал к окончанию разговора.

Она посмотрела на вентиляционный люк и принюхалась. Но запах шел не оттуда, его источник находился где-то поблизости. Сьюзан посмотрела на решетчатую дверь, ведущую в кухню, и в тот же миг поняла, что означает этот запах.

Создатель последнего шифра, который никто никогда не взломает. Сьюзан долго молчала. - Но… это значит… Стратмор посмотрел ей прямо в глаза: - Да. Энсей Танкадо только что превратил ТРАНСТЕКСТ в устаревшую рухлядь. ГЛАВА 6 Хотя Энсей Танкадо еще не родился, когда шла Вторая мировая война, он тщательно изучал все, что было о ней написано, - особенно о кульминации войны, атомном взрыве, в огне которого сгорело сто тысяч его соотечественников.

 Встретимся в Стоун-Мэнор. Она кивнула, и из ее глаз потекли слезы. - Договорились. - Агент Смит! - позвал Фонтейн. Из-за спины Беккера появилось лицо Смита.

Сьюзан отвечала на те вопросы, на которые могла ответить, и постепенно у Дэвида сложилось общее представление об Агентстве национальной безопасности - за исключением, разумеется, секретных сторон деятельности этого учреждения.

Сьюзан высвободилась из рук обмякшего Хейла, не понимая, что произошло. Стратмор подхватил ее и слегка обнял, пытаясь успокоить. - Ш-ш-ш, - утешал он.  - Это. Теперь все в порядке.

Беккер оказался зажат между двумя полными женщинами с закрытыми глазами, предоставившими толпе нести их в собор. Они беззвучно молились, перебирая пальцами четки. Когда толпа приблизилась к мощным каменным стенам почти вплотную, Беккер снова попытался вырваться, но течение стало еще более интенсивным. Трепет ожидания, волны, сносившие его то влево, то вправо, закрытые глаза, почти беззвучное движение губ в молитве.
