Evidence for Supermassive Black Hole Binaries
Martin G. H. Krause, Martin A. Bourne, Silke Britzen +10
We review the state of the evidence for the existence and observational appearance of supermassive black hole binaries. Such objects are expected from standard hierarchical galaxy…
Searching for the Highest-z Dual AGN in the Deepest Chandra Surveys
Brandon Sandoval, Adi Foord, Steven W. Allen +9
We present an analysis searching for dual AGN among 62 high-redshift () X-ray sources selected from publicly available deep Chandra fields. We aim to quantify the fr…
Surveying the onset and evolution of supermassive black holes at high-z with AXIS
Nico Cappelluti, Adi Foord, Stefano Marchesi +8
The nature and origin of supermassive black holes (SMBHs) remain an open matter of debate within the scientific community. While various theoretical scenarios have been proposed, e…
Tracking Supermassive Black Hole Mergers from kpc to sub-pc Scales with AXIS
Adi Foord, Nico Cappelluti, Tingting Liu +8
We present an analysis showcasing how the Advanced X-ray Imaging Satellite (AXIS), a proposed NASA Probe-class mission, will significantly increase our understanding of supermassiv…
Massive Black Hole Binaries as LISA Precursors in the Roman High Latitude Time Domain Survey
Zoltán Haiman, Chengcheng Xin, Tamara Bogdanović +27
With its capacity to observe faint active galactic nuclei (AGN) out to redshift , Roman is poised to reveal a population of b…
