... We find that XBONGS are not a single class of object, but fall into four categories -- red early-type galaxies, blue ellipticals, spiral/irregular galaxies and galaxies with AGN colors. ...
... 10% of the sample and use this complete survey to study the global properties of the galaxies in the sample, including color versus morpological type, color versus luminosity, the interal extinction in spiralgalaxies from color versus inclination ...
... nearby early-type galaxies and the bulges of nearby spirals (including the Milky Way ... Chandra exposures of nearby elliptical galaxies and spiral bulges have pushed the ...
... Yet the nature of these galaxies -- dusty elliptical galaxies, star-forming spirals, or `train-wreck' mergers -- has remained elusive because of the small areas and limited spatial resolution of previous mid-IR surveys. ...
... INTRODUCTION M33 is a late-type spiralgalaxy, Sc II Y III, and the third largest galaxy in the Local Group. ... since morphologically it is of intermediate type between the large early-type spiralgalaxies and the numerous dwarf galaxies ...

... a clean sample of LMXBs with no contamination by HMXBs, which are likely to contribute to the X-ray source populations of spiralgalaxies (the Milky Way and M31) and young or rejuvenated E and S0 galaxies resulting from recent mergers (e.g., NGC 5128 ...
