Formation of Supermassive Black Hole Seeds [PDF]
Publications of the Astronomical Society of Australia, 2016 AbstractThe detection of quasars at z > 6 unveils the presence of supermassive black holes of a few billion solar masses. The rapid formation process of these extreme objects remains a fascinating and open issue. Such discovery implies that seed black holes must have formed early on, and grown via either rapid accretion or BH/galaxy mergers.

, 2019 Understanding the processes that drive galaxy formation and shape the observed properties of galaxies is one of the most interesting and challenging frontier problems of modern astrophysics. We now know that the evolution of galaxies is critically shaped by the energy injection from accreting supermassive black holes (SMBHs). However, it is unclear how Ruszkowski, Mateusz, Nagai, Daisuke, Zhuravleva, Irina, Brummel-Smith, Corey, Li, Yuan, Hodges-Kluck, Edmund, Yang, Hsiang-Yi Karen, Basu, Kaustuv, Chluba, Jens, Churazov, Eugene, Donahue, Megan, Fabian, Andrew, Faucher-Giguère, Claude-André, GASPARI, MASSIMO, Hlavacek-Larrondo, Julie, McDonald, Michael, McNamara, Brian, Nulsen, Paul, Mroczkowski, Tony, Mushotzky, Richard, Reynolds, Christopher, Vikhlinin, Alexey, Voit, Mark, Werner, Norbert, ZuHone, John, Zweibel, Ellen +25 moreopenaire +4 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.
