Dr. Carles Badenes is a Chandra postdoctoral fellow at Princeton, having spent the previous few years at Rutgers University. His main research focus is on supernova explosions and supernova remnants, particularly the class known as Type Ia.
Dr. Patrick Slane from the Chandra X-ray Center recently shared some information on the G292.0+1.8 supernova remnant with NASA's museum alliance. Part II of this conversation talks more on what we're seeing in the Chandra image....
