Black Holes, Mergers, and the Entropy Budget of the Universe [PDF]
JCAP 0311 (2003) 011, 2002 Vast amounts of entropy are produced in black hole formation, and the amount
of entropy stored in supermassive black holes at the centers of galaxies is now
much greater than the entropy free in the rest of the universe.Abrahams A M (Binary Black Hole Grand Challenge Alliance Collaboration), Anninos P, Anninos P, Barr S M, Baumgarte T W, Flanagan E E, Holman R, Janka H T, Kamionkowski M, Macchetto E D, Postnov K A, Rees M J, Saijo M, Shibata M, Silk J, Starkman G D, Thomas W Kephart, Tinto M, Totani T, Valageas P, Wilson J R, Y Jack Ng, Yungelson L +22 morecore +3 more sourcesFormation of supermassive black hole seeds [PDF]
Publications Astronomical Society of Australia, 2016 The detection of quasars at $z>6$ unveils the presence of supermassive black
holes (BHs) of a few billion solar masses. The rapid formation process of these
extreme objects remains a fascinating and open issue.Ferrara, Andrea, Latif, Muhammad A.core +3 more sourcesThe NANOGrav 15 yr Data Set: Constraints on Supermassive Black Hole Binaries from the Gravitational-wave Background [PDF]
Astrophysical Journal Letters, 2023 The NANOGrav 15 yr data set shows evidence for the presence of a low-frequency gravitational-wave background (GWB). While many physical processes can source such low-frequency gravitational waves, here we analyze the signal as coming from a population of G. Agazie, A. Anumarlapudi, A. Archibald, P. Baker, B.

Astrophysical Journal Letters, 2023 Evidence for a low-frequency stochastic gravitational-wave background has recently been reported based on analyses of pulsar timing array data. The most likely source of such a background is a population of supermassive black hole binaries, the loudest ...G. Agazie, A. Anumarlapudi, A. Archibald, Z. Arzoumanian, P. Baker, B. B'ecsy, L.
