This talk will discuss the possible implications of the recently
scheduled XMM-Newton observations of 6 nearby, bulge dominated giant low
surface brightness (GLSB) galaxies. They have diffuse stellar disks and massive
HI disks but are overall poor in star formation. They are possibly the most
dark matter dominated spirals in our nearby universe and yet a significant fraction
of them have prominent bulges that host AGN activity. Optical studies indicate
that their AGN black hole masses are low compared to their galaxy masses and
lie below the M-sigma correlation. Not much is known about the AGN activity
and bulge evolution in these galaxies, especially in the X-ray domain.
XMM-Newton observations will be used to detect and characterize the X-ray properties
of these systems.
