"Usually, the stars at the centers of galaxy clusters are old and dead, essentially fossils," said Tracy Webb of McGill University, Montreal, Canada, lead author of a new paper on the findings accepted for publication in the Astrophysical Journal. "But we think the giant galaxy at the center of this cluster is furiously making new stars after merging with a smaller galaxy."
McGill professor Vicky Kaspi, a world-renowned astrophysicist known for her cutting-edge work on neutron stars and pulsars, was awarded the Killam Prize today, one of the country’s most prestigious awards for academic-career achievement. The $100,000 prize was granted for outstanding scholarship in the natural sciences. Five awards – one each in the categories of the humanities, social sciences, natural sciences, health sciences and engineering -- are distributed every year by the Canada Council for the Arts.
Brief pulse detected by Arecibo telescope appears to come from far beyond our galaxy
Observations with the Atacama Large Millimeter/submillimeter Array (ALMA) show that the most vigorous bursts of star birth in the cosmos took place much earlier than previously thought. The results are published in a set of papers to appear in the journal Nature and in the Astrophysical Journal. The research is the most recent example of the discoveries coming from the new international ALMA observatory, which celebrates its inauguration today.
