Small blue galaxy could shed new light on Big Bang, IU astronomers say

Professor John Salzer of the IU Bloomington College of Arts and Sciences Department of Astronomy reached out to IU Communications in March that he and several colleagues had a paper accepted for publication in the Astrophysical Journal.


Galaxy AGC 198691

The study found that Galaxy AGC 198691 — nicknamed “Leoncino” — contains the lowest level of heavy chemical elements, or “metals,” ever observed in a gravitationally bound system of stars, a unique quality suggesting the galaxy was largely unchanged in chemical composition from the birth of the universe during the Big Bang.

Working with Salzer and his graduate student Alec Hirschauer, IU Communications prepared a release on the research. The announcement was distributed as an IU news release and posted to EurekAlert on May 12, the date of the journal publication. Media outlets to carry the news included:

Other news sites to carry the news were EarthSky, Gizmag, International Business Times, iTech Post, Modern Readers, Nature World News, News Nation, NH Voice, PC-Tablet, Pulse Headlines, R&D Magazine, Sci-Tech Today, Science Explorer, Science News, Science World Report, Siasat Daily, The Space Reporter, Sputnik News, WCCF Tech and ZME Science.

The story was also posted to the twitter account of the SETI Institute and appeared in translation on the official websites of the Italian Space Agency and Italian National Institute for Astrophysics.
