Document Summary
Lecture 28: march 22nd, 2013 recall: blackholes are supernovas that continue to collapse recall: mass tells space how to curve and space tells matter how to move this is space-time. Detecting blackholes in binaries can see the matter spiralling in: can determine mass of accreting object & show it is >3 solar masses in such a small area there is nothing else it could be. Cygnus x-1 is a blackhole we can see from earth (not with your eyes) x stands for x-ray force. Disk component: stars of all ages, dust & gas clouds. Bulge & halo components: old stars, not much gas or dust: elliptical galaxy. Biggest galaxies in the universe looks like big star it is the light of billions stars together shaped like footballs. Phys 183 the milky way inside and out tracy webb. Winter 2013 like a very large spiral bulge.
