Overmassive Black Holes in Dwarf Galaxies Out to z ∼ 0.9 in the VIPERS Survey [PDF]
The Astrophysical Journal Letters, 2023 Supermassive black holes (SMBHs) are thought to originate from early universe seed black holes of mass M _BH ∼ 10 ^2 –10 ^5 M _⊙ and grown through cosmic time. Such seeds could be powering the active galactic nuclei (AGN) found in today’s dwarf galaxies.

Cosmological physics with black holes (and possibly white dwarfs) [PDF]
New Astronomy Reviews, 2008 The notion that microparsec-scale black holes can be used to probe gigaparsec-scale physics may seem counterintuitive, at first. Yet, the gravitational observatory LISA will detect cosmologically-distant coalescing pairs of massive black holes, accurately measure their luminosity distance and help identify an electromagnetic counterpart or a host ...

Tidal Stripping of a White Dwarf by an Intermediate-mass Black Hole [PDF]
The Astrophysical Journal, 2023 Abstract During the inspiralling of a white dwarf (WD) into an intermediate-mass black hole (∼102−5 M ⊙), both gravitational waves (GWs) and electromagnetic (EM) radiation are emitted. Once the eccentric orbit’s pericenter radius approaches the tidal radius, the WD would be tidally stripped upon each ...

The origins of off-centre massive black holes in dwarf galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Massive black holes often exist within dwarf galaxies, and both simulations and observations have shown that a substantial fraction of these may be off-centre with respect to their hosts. We trace the evolution of off-centre massive black holes (MBHs) in dwarf galaxies using cosmological hydrodynamical simulations, and show that

Tidal disruption of white dwarfs by intermediate mass black holes [PDF]
EPJ Web of Conferences, 2012 Modeling ultra-close encounters between a white dwarf and a spinning, intermediate mass black hole requires a full general relativistic treatment of gravity. This paper summarizes results from such a study.

Transmuted Gravity Wave Signals from Primordial Black Holes
Physics Letters B, 2018 Primordial black holes (PBHs) interacting with compact stars in binaries lead to a new class of gravity wave signatures that we explore. A small $10^{-16} - 10^{-7} M_{\odot}$ PBH captured by a neutron star or a white dwarf will eventually consume the ...

Multimessenger Signatures of Massive Black Holes in Dwarf Galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 Recent discoveries of massive black holes (MBHs) in dwarf galaxies suggest that they may have a more common presence than once thought. Systematic searches are revealing more candidates, but this process could be accelerated by predictions from simulations.

AT2018kzr: the merger of an oxygen–neon white dwarf and a neutron star or black hole [PDF]
, 2020 We present detailed spectroscopic analysis of the extraordinarily fast-evolving transient AT2018kzr. The transient's observed lightcurve showed a rapid decline rate, comparable to the kilonova AT2017gfo.
