The Astronomer's Telegram (ATel) is an internet service for quickly disseminating information about events relevant for astronomers. Examples include gamma-ray bursts,〔(Gamma signature, Astronomer's Telegram cast light on dazzling blazar ),''Symmetry'', 30 April 2009〕 microlenses, supernovae, novae, or X-ray transients, but there are no restrictions on content matter. The Astronomer's Telegram was launched on 17 December 1997 by Robert E. Rutledge with the goal of rapidly (<1 s) sharing information of interest to astronomers. Telegrams are sent out daily by email, but especially time sensitive events can be transmitted instantly. Since 2013, information is also broadcast over Twitter and Facebook. To publish, astronomers request credentials. Credentials are issued to professional astronomers and graduate students, after verification by personal contact.〔 Once credentials have been supplied and telegrams authorized, astronomers can publish telegrams directly, with no further editing.〔(【引用サイトリンク】url=http://www.astronomerstelegram.org/?inform )〕 As of March 2015, over 7000 telegrams have been published. == History == While working at Max Planck Institute for Extraterrestrische Physik in Garching, Bob Rutledge began the site after his experience in using the web in 1995-6 as an aid in the discovery and characterization (by multiple scientists working informally and collaboratively) of the Bursting Pulsar, GRO J1744-28. Operations began in earnest at the department of astronomy of UC Berkeley where Rutledge was a visiting post-doctoral scholar with Prof. Lars Bildsten. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Astronomer's Telegram」の詳細全文を読む スポンサード リンク
