Search for intermediate mass black hole binaries in the first and second observing runs of the Advanced LIGO and Virgo network [PDF]

, 2019
Gravitational-wave astronomy has been firmly established with the detection of gravitational waves from the merger of ten stellar-mass binary black holes and a neutron star binary.

Radiative properties and QPOs around charged black hole in Kalb–Ramond gravity

European Physical Journal C: Particles and Fields
Studies of accretion disc luminosities and quasiperiodic oscillations around black holes may help us understand the gravitational properties of black hole spacetime.

An Intermediate-Mass Black Hole in the Globular Cluster G1: Improved Significance from New Keck and Hubble Space Telescope Observations

, 2005
We present dynamical models for the massive globular cluster G1. The goal is to measure or place a significant upper limit on the mass of any central black hole.

A Tale of Two Black Holes: Multiband Gravitational-wave Measurement of Recoil Kicks

The Astrophysical Journal
The nonlinear dynamics of General Relativity leave their imprint on remnants of black hole mergers in the form of a recoil “kick.” The kick has profound astrophysical implications across the black hole mass spectrum, from stellar-mass to supermassive ...

The GstLAL template bank for spinning compact binary mergers in the second observation run of Advanced LIGO and Virgo [PDF]

, 2018
We describe the methods used to construct the aligned-spin template bank of gravitational waveforms used by the GstLAL-based inspiral pipeline to analyze data from the second observing run of Advanced LIGO and Virgo.

Spectrophotometric Reverberation Mapping of Intermediate-mass Black Hole NGC 4395

The Astrophysical Journal
Understanding the origins of massive black hole seeds and their coevolution with their host galaxy requires studying intermediate-mass black holes (IMBHs) and estimating their mass.

Intermediate Mass Black Hole Induced Quenching of Mass Segregation in Star Clusters [PDF]

, 2008
In many theoretical scenarios it is expected that intermediate-mass black holes (IMBHs, with masses M ~ 100-10000 solar masses) reside at the centers of some globular clusters. However, observational evidence for their existence is limited.

Optical Continuum Reverberation Mapping of a Candidate IMBH in a Nearby Seyfert 1 Galaxy

The Astrophysical Journal
To investigate the short-term variability and determine the size of the optical continuum emitting region of intermediate-mass black holes (IMBHs), we carried out high-cadence, multiband photometric monitoring of a Seyfert 1 galaxy J0249−0815 across two ...

Can the Known Millisecond Pulsars Help in the Detection of Intermediate-Mass Black Holes at the Centers of Globular Clusters?

, 2008
We consider the possibility of detecting intermediate-mass ($10^3-10^4 M_{\odot}$) black holes, whose existence at the centers of globular clusters is expected from optical and infrared observations, using precise pulse arrival timing for the millisecond

Constraints on metric-Palatini gravity from QPO data

European Physical Journal C: Particles and Fields
In this work, we study metric-Palatini gravity extended by the antisymmetric part of the affine curvature. This gravity theory leads to general relativity plus a geometric Proca field.
