Simulating Black Hole White Dwarf Encounters [PDF]
Computer Physics Communications, 2008 The existence of supermassive black holes lurking in the centers of galaxies and of stellar binary systems containing a black hole with a few solar masses has been established beyond reasonable doubt.

Black dwarf supernova in the far future [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT In the far future, long after star formation has ceased, the universe will be populated by sparse degenerate remnants, mostly white dwarfs, though their ultimate fate is an open question. These white dwarfs will cool and freeze solid into black dwarfs while pycnonuclear fusion will slowly process their composition to iron-56 ...

The Active Fraction of Massive Black Holes in Dwarf Galaxies [PDF]
The Astrophysical Journal, 2021 Abstract The population of massive black holes (MBHs) in dwarf galaxies is elusive, but fundamentally important to understand the coevolution of black holes with their hosts and the formation of the first collapsed objects in the universe.

Hunting for massive black holes in dwarf galaxies [PDF]
Nature Astronomy, 2022 Despite traditional thinking, an appreciable population of massive black holes may be lurking in dwarf galaxies. Prior to the last decade, nearly all massive black holes were found in the nuclei of giant galaxies and the existence of massive black holes in dwarf galaxies was highly controversial.

Constraining Primordial Black Holes with Dwarf Galaxy Heating [PDF]
The Astrophysical Journal Letters, 2021 Abstract Black holes formed in the early universe, prior to the formation of stars, can exist as dark matter and also contribute to the black hole merger events observed in gravitational waves. We set a new limit on the abundance of primordial black holes (PBHs) by considering interactions of PBHs with the interstellar medium, which ...

A Supermassive Black Hole in an Ultracompact Dwarf Galaxy [PDF]
Nature, 2014 Ultracompact dwarf galaxies (UCDs) are among the densest stellar systems in the universe. These systems have masses up to 200 million solar masses, but half light radii of just 3-50 parsecs.

Dwarf galaxies and the black hole scaling relations [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2020 ABSTRACT The sample of dwarf galaxies with measured central black hole masses M and velocity dispersions σ has recently doubled, and gives a close fit to the extrapolation of the M - σ relation for more massive galaxies. We argue that this is difficult to reconcile with suggestions that the scaling relations between galaxies and their ...

Cusp Disruption in Minor Mergers [PDF]
, 2001 We present 0.55 x 10^6 particle simulations of the accretion of high-density dwarf galaxies by low-density giant galaxies, using models that contain both power-law central density cusps and point masses representing supermassive black holes.

Gravitational waves from cosmological compact binaries [PDF]
, 2000 We consider gravitational waves emitted by various populations of compact binaries at cosmological distances. We use population synthesis models to characterize the properties of double neutron stars, double black holes and double white dwarf binaries as
