Why a Windy Torus?
S. C. Gallagher, M. M. Abado, J. E. Everett +2
Mass ejection in the form of winds or jets appears to be as fundamental to quasar activity as accretion, and can be directly observed in many objects with broadened and blue-shifte…
Stacking Star Clusters in M51: Searching for Faint X-Ray Binaries
N. Vulic, P. Barmby, S. C. Gallagher
The population of low-luminosity (< 10^35 erg/s) X-Ray Binaries (XRBs) has been investigated in our Galaxy and M31 but not further. To address this problem, we have used data from…
Looking for the Wind in the Dust
S. C. Gallagher, J. E. Everett, S. K. Keating +2
The blue-shifted broad emission lines and/or broad absorption lines seen in many luminous quasars are striking evidence for a broad line region in which radiation driving plays an…
The merger history, AGN and dwarf galaxies of Hickson Compact Group 59
I. S. Konstantopoulos, S. C. Gallagher, K. Fedotov +16
Compact group galaxies often appear unaffected by their unusually dense environment. Closer examination can, however, reveal the subtle, cumulative effects of multiple galaxy inter…
Star Clusters as Tracers of Interactions in Stephan's Quintet (Hickson Compact Group 92)
K. Fedotov, S. C. Gallagher, I. S. Konstantopoulos +5
Stephan's Quintet (SQ) is a compact group of galaxies that exhibits numerous signs of interactions between its members. Using high resolution images of SQ in B438, V606, and I814 b…
