Meet the Parents: The Progenitor Binary for the Supermassive Black Hole Candidate in E1821+643
The Astrophysical Journal Letters, 2023 The remnants of binary black hole mergers can be given recoil kick velocities up to 5000 km s ^−1 due to anisotropic emission of gravitational waves. E1821+643 is a recoiling supermassive black hole candidate with spectroscopically offset, broad emission

Origin of supermassive black holes [PDF]
arXiv, 2007 The origin of supermassive black holes in the galactic nuclei is quite uncertain in spite of extensive set of observational data. We review the known scenarios of galactic and cosmological formation of supermassive black holes. The common drawback of galactic scenarios is a lack of time and shortage of matter supply for building the supermassive black ...

A Unified, Merger-driven Model of the Origin of Starbursts, Quasars, the Cosmic X-Ray Background, Supermassive Black Holes, and Galaxy Spheroids [PDF]
, 2005 We present an evolutionary model for starbursts, quasars, and spheroidal galaxies in which mergers between gas-rich galaxies drive nuclear inflows of gas, producing starbursts and feeding the buried growth of supermassive black holes (BHs) until feedback

Massive and supermassive black holes in the contemporary and early Universe and problems in cosmology and astrophysics [PDF]
, 2017 We discuss recent astronomical data showing that the role of massive primordial black holes in the Universe is much more significant than previously thought, both for the present Universe and for redshifts of the order of 10.

THE SUPERMASSIVE BLACK HOLE IN M84 REVISITED [PDF]
The Astrophysical Journal, 2010 The mass of the central black hole in the giant elliptical galaxy M84 has previously been measured by two groups using the same observations of emission-line gas with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope, giving strongly discrepant results: Bower et al. (1998) found M_BH = (1.5^{+1.1}_{-0.6}) x 10^9 M_sun, while

The Astrophysical JournalMany stellar-mass black holes (sBHs) are expected to orbit supermassive black holes at galactic centers. For galaxies with active galactic nuclei, it is likely that the sBHs reside in a disk.

To test dual supermassive black hole model for broad line AGN with double-peaked narrow [OIII] lines [PDF]
arXiv, 2016 In this manuscript, we proposed an interesting method to test the dual supermassive black hole model for AGN with double-peaked narrow \oiii lines (double-peaked narrow emitters), through their broad optical Balmer line properties. Under the dual supermassive black hole model for double-peaked narrow emitters, we could expect statistically smaller ...

SWIFT COALESCENCE OF SUPERMASSIVE BLACK HOLES IN COSMOLOGICAL MERGERS OF MASSIVE GALAXIES [PDF]
, 2016 Supermassive black holes (SMBHs) are ubiquitous in galaxies with a sizable mass. It is expected that a pair of SMBHs originally in the nuclei of two merging galaxies would form a binary and eventually coalesce via a burst of gravitational waves.

A Comparison of the X-Ray Polarimetric Properties of Stellar and Supermassive Black Holes
The Astrophysical JournalX-ray polarization provides a new way to probe accretion geometry in black hole systems. If the accretion geometry of black holes is similar regardless of mass, we should expect the same to be true of their polarization properties.
