SHAO Astrophysics Colloquia 

Gamma Ray Bursts: Connections to Supernovae and Cosmology?

    Speaker: Péter Mészáros (Penn State)

    Time: Monday,3:00pm,October 21th

    Location: Lecture Hall, 3rd floor 

    Abstract: I will review recent GRB observational results from The Fermi and Swift satellite, as well recent IceCube limits, and will discuss current theoretical GRB models and how they compare to these observations and constraints 

 News from around our central supermassive black hole

    Speaker: Q. Daniel Wang (University of Massachusetts)

    Time: Thursday, 3:00pm, October 24th

    Location: Lecture Hall,3rd floor 

    Abstract: Essentially all major galaxies are believed to contain a supermassive black hole at their centers. But such black holes are typically very dim, unlike their counterparts in the distant universe. The question is why. Several ongoing events are shedding lights on Sgr A* - the ultra-dim supermassive black hole at the center of the Milky Way. These include 1) a cool gas cloud being tidally destructed by the black hole, 2) its ejection of > 99% of the matter captured, and 3) a magnetar appearing less than 3" away. These events have been providing new and unique opportunities of exciting research on the black hole, leading to the understanding of similar phenomena and processes in nuclear regions of other galaxies.
