A close quasar pair in a disk-disk galaxy merger at z = 2.17
Yu-Ching Chen, Xin Liu, Adi Foord +7
Galaxy mergers produce pairs of supermassive black holes (SMBHs), which may be witnessed as dual quasars if both SMBHs are rapidly accreting. The kiloparsec (kpc)-scale separation…

Lensing in the Darkness: A Bayesian Analysis of 22 Chandra Sources at Shows No Evidence of Lensing
Fabio Pacucci, Adi Foord, Lucia Gordon +1
More than quasars have been detected so far at , with only one showing clear signs of strong gravitational lensing. Some studies call for a missing population of lense…

Massive black hole formation in dense stellar environments: Enhanced X-ray detection rates in high velocity dispersion nuclear star clusters
Vivienne F. Baldassare, Nicholas C. Stone, Adi Foord +2
We analyze Chandra X-ray Observatory imaging of 108 galaxies hosting nuclear star clusters (NSCs) to search for signatures of massive black holes (BHs). NSCs are extremely dense st…
