Cosmological Budget of Entropy from Merging Black Holes
Siyuan Chen, Karan Jani, Thomas W. Kephart
Black holes contain more entropy than any other component of the observable universe. Gravitational-wave observations from LIGO and Virgo have shown evidence of a previously unknow…

Deep Neural Emulation of the Supermassive Black-hole Binary Population
Nima Laal, Stephen R. Taylor, Luke Zoltan Kelley +13
While supermassive black-hole (SMBH)-binaries are not the only viable source for the low-frequency gravitational wave background (GWB) signal evidenced by the most recent pulsar ti…

Distinguishing the Demographics of Compact Binaries with Merger Entropy Index
Siyuan Chen, Karan Jani
The coalescence of binary black holes and neutron stars increases the entropy in the universe. The release of entropy from the inspiral stage to the merger depends primarily on the…
