Free Public Program starts at 7:00 PM folllowed by the Regular Business Meeting starting about 8:30 PM (open to public)
PROGRAM
Dr. Farhad Yusef-Zadeh, Professor at Northwestern University, will discuss his latest research in Astronomy. Dr Zadeh has presented many times to LCAS in the past and this is sure to be a very educational and informative talk.
The Galactic center is an active region of our Milky Way Galaxy. There is a supermassive black hole, called Sgr A*, at the center of the Galaxy. Beyond the sphere of influence of the black hole, there is a rich environment revealing relic of past activities of the black hole.
Dr Zadeh will discuss two mysterious aspects of recent observations carried out with James Webb and MeerKAT telescopes. One describes preliminary results of infrared monitoring of Sgr A* with JWST for the first time. These measurements indicate that Sgr A* is constantly varying on hourly and daily time scales. The other focuses on recent radio observations using the new South African MeerKAT observatory. These measurements have discovered hundreds of magnetized thread-like filaments in the inner 1000 light years of the Galactic center. Both JWST and MeerKAT observations have been a gold mine in the study of this complex region of the Galaxy. The nature and origin of these structures will be discussed with an emphasis of why it is so
puzzling to understand them.
Afterwards LCAS members will show guests the night sky through powerful telescopes (weather permitting). Please join us.
