Gravitational Self-Lensing in Populations of Massive Black Hole Binaries

Luke Zoltan Kelley, Daniel J. D'Orazio, Rosanne Di Stefano

The community may be on the verge of detecting low-frequency gravitational waves from massive black hole binaries (MBHBs), but no examples of binary active galactic nuclei (AGN) ha…

The NANOGrav 11yr Data Set: Limits on Supermassive Black Hole Binaries in Galaxies within 500Mpc

Zaven Arzoumanian, Paul T. Baker, Adam Brazier +54

Supermassive black hole binaries (SMBHBs) should form frequently in galactic nuclei as a result of galaxy mergers. At sub-parsec separations, binaries become strong sources of low-…

Seeds Don't Sink: Even Massive Black Hole "Seeds" Cannot Migrate to Galaxy Centers Efficiently

Linhao Ma, Philip F. Hopkins, Xiangcheng Ma +3

Possible formation scenarios of supermassive black holes in the early universe include rapid growth from less massive seed black holes (BHs) via super-Eddington accretion or runawa…

The NANOGrav 12.5-year Data Set: Search For An Isotropic Stochastic Gravitational-Wave Background

Zaven Arzoumanian, Paul T. Baker, Harsha Blumer +58

We search for an isotropic stochastic gravitational-wave background (GWB) in the -year pulsar timing data set collected by the North American Nanohertz Observatory for Gravit…

The effect of differential accretion on the Gravitational Wave Background and the present day MBH Binary population

Magdalena S. Siwek, Luke Zoltan Kelley, Lars Hernquist

Massive black hole binaries (MBHBs) form as a consequence of galaxy mergers. However, it is still unclear whether they typically merge within a Hubble time, and how accretion may a…

Considerations for the Observability of Kinematically Offset Binary AGN

Luke Zoltan Kelley

The gravitational waves from Massive black-hole (MBH) binaries are expected to be detected by pulsar timing arrays in the next few years. While they are a promising source for mult…
