March Monthly Meeting Guest Speaker: Dr. James DiFrancesco- The Secret Sits.

Posted by as Meetings

“The Secret Sits: What’s in Our Galactic Centre?”

“I will discuss recent observations of the very centre of the Milky Way galaxy.  At ~8 kpc from the Sun, the Central Parsec is filled thousands of stars, but also most interestingly a supermassive black hole named Sgr A*.  This curious object is our closest Galactic Nucleus, and will soon  be observed at extraordinarily high resolution (~15 micro-arcseconds) using a world-wide network of high-frequency radio telescopes in a very coordinated effort to detect accretion disk close to its event horizon.”
James Di Francesco is an RASC member who works at the NRC Herzberg Programs in Astronomy and Astrophysics.  He was born in Ontario and received his BSc in Astronomy and Physics at the University of Toronto in 1990, and his PhD in Astronomy at The University of Texas at Austin in 1997.  After completing postdoctoral appointments at the Harvard-Smithsonian Center for Astrophysics in Cambridge, MA and the University of California, Berkeley, James joined NRC in 2002.
