A First Look at Giant Bulge-Dominated Low-Surface Brightness Galaxies

Low surface brightness galaxies (LSBs) might appear optically unimpressive, but the largest LSBs contain as many stars as the largest normal elliptical and spiral galaxies. Next to nothing is known about their X-ray properties. We propose moderate length Chandra observations of three giant, bulge-dominated LSBs that cover over an order of magnitude in L_K to firmly detect for the first time the expected hot gaseous bulge emission from these systems, and compare their L_X/L_K scaling relation with normal early-type spiral bulges/ellipticals. We will also search for ULXs in the faint disks of these intriguing systems.
