A hard X-ray view of Luminous and Ultra-luminous Infrared Galaxies in GOALS: I - AGN obscuration along the merger sequence
C. Ricci, G. C. Privon, R. W. Pfeifle +25
The merger of two or more galaxies can enhance the inflow of material from galactic scales into the close environments of Active Galactic Nuclei (AGN), obscuring and feeding the su…
The Discovery of a Hidden Broad Line AGN in a Bulgeless Galaxy: Keck NIR Spectroscopic Observations of SDSS J085153.64+392611.76
Thomas Bohn, Gabriela Canalizo, Shobita Satyapal +1
We report the discovery of a buried, active supermassive black hole in SDSS J085153.64+392611.76, a bulgeless Seyfert 2 (Sy2) galaxy. Keck near-infrared observations reveal a hidde…
Multi-wavelength observations of SDSS J105621.45+313822.1, a broad-line, low-metallicity AGN
Jenna M. Cann, Shobita Satyapal, Thomas Bohn +8
In contrast to massive galaxies with Solar or super-Solar gas phase metallicities, very few Active Galactic Nuclei (AGN) are found in low-metallicity dwarf galaxies. Such a populat…
Very long baseline interferometry observation of the triple AGN candidate J0849+1114
Krisztina Éva Gabányi, Sándor Frey, Shobita Satyapal +2
In the hierarchical structure formation model, galaxies grow through various merging events. Numerical simulations indicate that the mergers can enhance the activity of the central…
A Triple AGN in a Mid-Infrared Selected Late Stage Galaxy Merger
Ryan W. Pfeifle, Shobita Satyapal, Christina Manzano-King +11
The co-evolution of galaxies and the supermassive black holes (SMBHs) at their centers via hierarchical galaxy mergers is a key prediction of CDM cosmology. As gas and dust are…
Buried Black Hole Growth in IR-selected Mergers: New Results from Chandra
Ryan W. Pfeifle, Shobita Satyapal, Nathan J. Secrest +8
Observations and theoretical simulations suggest that a significant fraction of merger-triggered accretion onto supermassive black holes is highly obscured, particularly in late-st…
