The power of infrared AGN selection in mergers: a theoretical study
Laura Blecha, Gregory F. Snyder, Shobita Satyapal +1
The role of galaxy mergers in fueling active galactic nuclei (AGN) is still debated, owing partly to selection effects inherent to studies of the merger/AGN connection. In particul…
Single Sources in the Low-Frequency Gravitational Wave Sky: properties and time to detection by pulsar timing arrays
Luke Zoltan Kelley, Laura Blecha, Lars Hernquist +2
We calculate the properties, occurrence rates and detection prospects of individually resolvable 'single sources' in the low frequency gravitational wave (GW) spectrum. Our simulat…
Buried AGNs in Advanced Mergers:Mid-infrared color selection as a dual AGN finder
Shobita Satyapal, Nathan J. Secrest, Claudio Ricci +7
A direct consequence of hierarchical galaxy formation is the existence of dual supermassive black holes (SMBHs), which may be preferentially triggered as active galactic nuclei (AG…
The Gravitational Wave Background from Massive Black Hole Binaries in Illustris: spectral features and time to detection with pulsar timing arrays
Luke Zoltan Kelley, Laura Blecha, Lars Hernquist +2
Pulsar Timing Arrays (PTA) around the world are using the incredible consistency of millisecond pulsars to measure low frequency gravitational waves from (super)Massive Black Hole…
Growing supermassive black holes in the late stages of galaxy mergers are heavily obscured
C. Ricci., F. E. Bauer, E. Treister +10
Mergers of galaxies are thought to cause significant gas inflows to the inner parsecs, which can activate rapid accretion onto supermassive black holes (SMBHs), giving rise to Acti…
