Supermassive Black Holes in Galactic Nuclei: Past, Present and Future Research

SUPERMASSIVE BLACK HOLES AND THEIR HOST SPHEROIDS. II. THE RED AND BLUE SEQUENCE IN THE MBH–M*,SPH DIAGRAM

“…This "rough scaling" was a premature version of the early correlations between black hole mass, M , BH and host spheroid luminosity, L , sph and also host spheroid mass, M sph (Kormendy & Richstone 1995;Magorrian et al 1998;Marconi & Hunt 2003;Häring & Rix 2004). These initial studies were dominated by high-mass, early-type galaxies, for which they too reported a quasi-linear M M diagrams (Ferrarese & Ford 2005;Graham 2007;Lauer et al 2007a;Gültekin et al 2009;Sani et al 2011;Beifiori et al 2012;Erwin & Gadotti 2012;van den Bosch et al 2012;Vika et al 2012;Kormendy & Ho 2013;McConnell & Ma 2013) continued to use galaxy samples dominated by highmass, early-type systems with M M 0.5 10 , BH 8 ´ and they too recovered a near-linear relation. However, the consensus about a linear M M BH sph -correlation was not unanimous.…”

The cosmological constant puzzle

“…Using the Hubble telescope, SMBH candidates have been observed in about 100 galaxies. There are strong correlations (scaling relations) between the masses of these supermassive black holes and the global properties of their host galaxies (including dark matter contributions) [18]. SMBHs have profound effects on both the dynamical and structure properties of the entire galaxy in which they reside, suggesting that they play an important role in the galaxy formation process.…”

Search for gamma rays from dark matter annihilations around intermediate mass black holes with the HESS experiment

“…IMBHs are compact objects with masses comprised between that of the heaviest remnant of a stellar collapse, $20M [49,50], and the lower end of the mass range of supermassive black holes (SMBH) $10 6 M [51,52].…”
