Hi TAPT-ers,
This is just a
quick reminder that our U of A breakfast meeting is Saturday, October 19th.
We will meet at 8:30 am in the PAS Building, Room 218. Only the West
doors will be open. Breakfast is generously supplied by the University of
Arizona Physics Department.
Our speaker
will be Dr. Sam Gralla, of the U of A Physics Department. He will talk about
the recent exciting picture of a black hole:
Understanding
the Photograph

Gralla, Department of Physics, University of Arizona
In April
of this year, the Event Horizon Telescope collaboration released the first ever
horizon-scale observations of the environment surrounding a black hole. I
will present the basics of light bending by black holes and discuss how to
understand the observations. This involves time dilation and the concept
of 'event horizon'.
Hope to see
everyone there!
Best,
Karie
