A Strong Correlation between Circumnuclear Dust and Black Hole Accretion in Early-Type Galaxies
Ramiro D. Simões Lopes, Thaisa Storchi-Bergmann, Maria de Fátima O. Saraiva +1
We present a detailed investigation of the incidence of circumnuclear dust structure in a large, well-matched sample of early-type galaxies with and without Active Galactic Nuclei…
Chandra Observations of Candidate "True" Seyfert 2 Nuclei
Himel Ghosh, Richard W. Pogge, Smita Mathur +2
The Unification Model for active galactic nuclei posits that Seyfert 2s are intrinsically like Seyfert 1s, but that their broad-line regions (BLRs) are hidden from our view. A Seyf…
The Connection Between Barstrength and Circumnuclear Dust Structure
Molly Peeples, Paul Martini
We present a comparison of barstrength Qb and circumnuclear dust morphology for 75 galaxies in order to investigate how bars affect the centers of galaxies. We trace the circumnucl…
Spectroscopic Confirmation of a Large AGN Population in Clusters of Galaxies
Paul Martini, Daniel D. Kelson, Eunhyeuk Kim +2
We have completed a spectroscopic survey of X-ray point sources in eight low-redshift clusters of galaxies (0.05<z<0.31) and have identified 40 cluster members with broad-band (0.3…
