AGN as Potential Factories for Eccentric Black Hole Mergers
J. Samsing, I. Bartos, D. J. D'Orazio +6
There is some weak evidence that the black hole merger named GW190521 had a non-zero eccentricity. In addition, the component black holes' masses exceeded the limit predicted by st…
Using Gravitational Wave Parallax to Measure the Hubble Parameter with Pulsar Timing Arrays
Daniel J. D'Orazio, Abraham Loeb
We demonstrate how pulsar timing arrays (PTAs) can, in principle, yield a purely gravitational wave (GW) measurement of the luminosity distance and comoving distance to a supermass…
Evolution of gas disc-embedded intermediate mass ratio inspirals in the LISA band
A. Derdzinski, D. D'Orazio, P. Duffell +2
Among the potential milliHz gravitational wave (GW) sources for the upcoming space-based interferometer LISA are extreme- or intermediate-mass ratio inspirals (EMRI/IMRIs). These e…
Chandra Observations of Candidate Sub-Parsec Binary Supermassive Black Holes
M. Lynne Saade, Daniel Stern, Murray Brightman +10
We present analysis of Chandra X-ray observations of seven quasars that were identified as candidate sub-parsec binary supermassive black hole (SMBH) systems in the Catalina Real-T…
