"The Jellyfish Nebula, Cosmic-Ray Accelerator"
The Jellyfish Nebula is a supernova remnant resulting from the explosion of a massive star. Its expanding shock wave accelerates cosmic rays. Today, we see that shock wave interacting with clouds of gas left over from the star's birth. We can study this fascinating nebula from the radio to the optical to very-high-energy gamma rays, learning about the structure and dynamics of the nebula, the acceleration of cosmic rays at its shocks, and even clues about the nature of the progenitor star.
Dr. Brian Humensky is a faculty member in the Physics Department at Columbia University and works on the gamma-ray observatory VERITAS. He is involved in development of the next-generation Cherenkov Telescope Array.
The meeting will be preceded by the brief but official WAA Annual Meeting, with the President's Report and election of officers.
There will be several door prizes at this meeting.
