These hot galaxies show signs of AGN and starburst activity occurring within their dusty interiors.
Astronomers have known for a while that GRBs are sign-posts to galaxies which are forming lots of stars. But today’s paper used radio observations of the gas to connect that star formation to a recent merger.
Recently we have been finding some crazy uses for these unmanned machines. Could investigating the universe be one of them?
The authors of today’s paper show that the locations of the protoplanetary gaps in HL Tau are to be expected from the condensation points of common ices in the disk.
What makes galaxies stop forming stars? Is gas removed entirely, or simply heated to prevent stars from forming? Today’s paper uses observations of carbon monoxide in post-starburst galaxies to try to answer this question.
