Accretion in Young Stars
What might be causing the accretion rates in newly formed stars to remain so high?
A Faint Black Hole?
The authors report the discovery of perhaps the faintest black hole x-ray binary. But this conclusion is limited by the uncertainty in the distance to the object.
Blank Sky But Not Blank Information
Archival data are able to place constraints on the origin of supernova 2011fe.
What Fed Sgr A* its Latest Meal?
The black hole at the center of our galaxy, Sgr A*, is a very picky eater. However, with the discovery of the G2 cloud, astronomers have had the opportunity to watch the infrequent feeding process in Sgr A* in action. While the origin of this cloud is still debated, research is beginning to suggest that G2 is a gas cloud that was ripped away from a giant star in orbit around our galaxy’s central black hole.
The Changing Faces of Active Galactic Nuclei
Has a multi-wavelength study of AGN across a large redshift range revealed that these energetic giants do not impact upon their host galaxy as significantly as previously thought?
Progenitors of AM CVn systems
The progenitors of a special type of cataclysmic variable, AM CVn, and possibly supernovae have been found.
