Title: Exploring X-ray - H(alpha) Connection to Test Galaxy Formation Theories
Abstract: Models of galaxy formation make specific predictions regarding the evolution of gas residing in the halos of disk galaxies. Recent observations from Chandra have detected the predicted diffuse X-ray emission from the cooling gas in some nearby bulge-dominated galaxies. We propose deep narrow-band imaging observations of H(alpha) emission to measure, or tightly constrain, the content and morphology of warm gas in four massive early-type disk galaxies. These observations, as part of our ongoing multi-wavelength study of these galaxies, will enable us to characterize the origin and evolution of various gaseous components and their relationship with other galaxy properties. This study will provide a critical link between our understanding of spirals and elliptical galaxies and may help constrain models of galaxy formation.
