Astronomy And Astrophysics
''Astronomy & Astrophysics (A&A)'' is a monthly peer-reviewed scientific journal covering theoretical, observational, and instrumental astronomy and astrophysics. It is operated by an editorial team under the supervision of a board of directors representing 27 sponsoring countries plus a representative of the European Southern Observatory. The journal is published by EDP Sciences and the current editors-in-chief are Thierry Forveille and João Alves. History Origins ''Astronomy & Astrophysics'' was created as an answer to the publishing situation found in Europe in the 1960s. At that time, multiple journals were being published in several countries around the continent. These journals usually had a limited number of subscribers, and articles were written in languages other than English. They were less widely read than American and British journals and the research they reported had therefore less impact in the community. Starting in 1963, conversations between astronomers from ...

Astronomy
Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall evolution. Objects of interest include planets, natural satellite, moons, stars, nebulae, galaxy, galaxies, meteoroids, asteroids, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond atmosphere of Earth, Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Egyptian astronomy, Egyptians, Babylonian astronomy, Babylonians, Greek astronomy, Greeks, Indian astronomy, Indians, Chinese astronomy, Chinese, Maya civilization, M ...

Gaia (spacecraft)
''Gaia'' was a space observatory of the European Space Agency (ESA) that was launched in 2013 and operated until March 2025. The spacecraft was designed for astrometry: measuring the positions, distances and motions of stars with unprecedented precision, and the positions of exoplanets by measuring attributes about the stars they orbit such as their apparent magnitude and color. , the mission data processing continues, aiming to construct the largest and most precise 3D space catalog ever made, totalling approximately 1 billion astronomical objects, mainly stars, but also planets, comets, asteroids and quasars, among others. To study the precise position and motion of its target objects, the spacecraft monitored each of them about 70 times over the five years of the nominal mission (2014–2019), and about as many during its extension. Due to its detectors not degrading as fast as initially expected, the mission was given an extension. As of March 2023, the spacecraft had en ...

Current Contents
''Current Contents'' is a rapid alerting service database from Clarivate, formerly the Institute for Scientific Information and Thomson Reuters. It is published online and in several different printed subject sections. History ''Current Contents'' was first published in paper format, in a single edition devoted only to biology and medicine. Other subject editions were added later. Initially, it consisted simply of a reproduction of the title pages from several hundred major peer-reviewed scientific journals, and was published weekly, with the issues containing title pages from journal issues only a few weeks previously, a shorter time lag than any service then available. There was an author index and a crude keyword subject index only. Author addresses were provided so readers could send reprint requests for copies of the actual articles. Status Still published in print, it is available as one of the databases included in Clarivate Analytics' Web of Science with daily updates, an ...

Subscribe To Open
Subscribe to Open (S2O) is an economic model used by peer-reviewed scholarly journals to provide readers with open access (OA) to the journal’s content, without charging costs to authors. S2O converts journals that have a traditional subscription model to open access. When the academic libraries subscribing to a journal are asked to renew their subscriptions to the journal, they are told that, with the libraries’ support, the journal will be made open access to all readers, while authors are able to publish in it at no cost. If enough libraries renew on these terms, the journal is converted to open access, and if not, access to the journal remains restricted to subscribing libraries. Background The term “Open Access” (OA) was first coined in December 2001 in a call for greater access to academic journal articles, which were mainly available through subscriptions. Influential statements such as the Budapest Open Access Initiative (BOAI) in February 14, 2002, have ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astrophysics Data System
The SAO/NASA Astrophysics Data System (ADS) is a digital library portal for researchers on astronomy and physics, operated for NASA by the Smithsonian Astrophysical Observatory. ADS maintains three bibliographic collections containing over 15 million records, including all arXiv e-prints. Abstracts and full-text of major astronomy and physics publications are indexed and searchable through the portal. Historical context Johann Friedrich Weidler published the first comprehensive history of astronomy in 1741 and the first astronomical bibliography in 1755. This was an effort to archive and classify earlier astronomical knowledge and works. This effort was continued by Jérôme de La Lande who published his ''Bibliographie astronomique'' in 1803, a work that covered the period from 480 BCE to the year of publication. The ''Bibliographie générale de l’astronomie, Volume I and Volume II'', published by J.C. Houzeau and A. Lancaster, followed in 1882 until 1889. As the numbe ...

Delayed Open Access Journal
Delayed open-access journals are traditional subscription-based journals that provide free online access upon the expiry of an embargo period following the initial publication date. Details The embargo period before an article is made available for free can vary from a few months to two or more years. In a 2013 study, 77.8% of delayed open access journals analyzed had an embargo of 12 months or less. 85.4% had an embargo period of 24 months or less. A journal subscription or an individual article purchase fee would be required to access the materials before this embargo period ends. Some delayed access journals also deposit their publications in open repositories when the author is bound by a delayed open-access mandate. The rationale for the access delay is to provide eventual access to all would-be users while still requiring the institutions An institution is a humanly devised structure of rules and norms that shape and constrain social behavior.

Article Processing Charge
An article processing charge (APC), also known as a publication fee, is a fee which is sometimes charged to authors. Most commonly, it is involved in making an academic work available as open access (OA), in either a full OA journal or in a hybrid journal. This fee may be paid by the author, the author's institution, or their research funder. Sometimes, publication fees are also involved in traditional journals or for paywalled content. Some publishers waive the fee in cases of hardship or geographic location, but this is not a widespread practice. An article processing charge does not guarantee that the author retains copyright to the work, or that it will be made available under a Creative Commons license. Background Journals use a variety of ways to generate the income required to cover publishing costs (including editorial costs, any costs of administering the peer review system), such as subsidies from institutions and subscriptions. A majority of open access journals do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
