Intermediate-Mass Black Holes
M. Coleman Miller, E. J. M Colbert
The mathematical simplicity of black holes, combined with their links to some of the most energetic events in the universe, means that black holes are key objects for fundamental p…
Elusive Active Galactic Nuclei
R. Maiolino, A. Comastri, R. Gilli +8
A fraction of active galactic nuclei do not show the classical Seyfert-type signatures in their optical spectra, i.e. they are optically "elusive". X-ray observations are an optima…
A high spatial resolution X-ray and H-alpha study of hot gas in the halos of star-forming disk galaxies. II. Quantifying supernova feedback
D. K. Strickland, T. M. Heckman, E. J. M. Colbert +2
We investigate how the empirical properties of hot X-ray-emitting gas in a sample of seven starburst and three normal edge-on spiral galaxies (a sample which covers the full range…
A high spatial resolution X-ray and H-alpha study of hot gas in the halos of star-forming disk galaxies. I. Spatial and spectral properties of the diffuse X-ray emission
D. K. Strickland, T. M. Heckman, E. J. M. Colbert +2
We present arcsecond resolution Chandra X-ray and ground-based optical H-alpha imaging of a sample of ten edge-on star-forming disk galaxies (seven starburst and three ``normal'' s…
Old and Young X-ray Point Source Populations in Nearby Galaxies
Edward Colbert, Tim Heckman, Andy Ptak +2
We analyzed 1441 Chandra X-ray point sources in 32 nearby galaxies. The total point-source X-ray luminosity L_XP is well correlated with B, K, and FIR+UV luminosities of spiral hos…
Chandra reveals a black-hole X-ray binary within the ultraluminous supernova remnant MF 16
T. P. Roberts, E. J. M. Colbert
We present evidence, based on Chandra ACIS-S observations of the nearby spiral galaxy NGC 6946, that the extraodinary X-ray luminosity of the MF 16 supernova remnant actually arise…
