Recently, Graham et al (2020 arXiv:2006.14122) identified ZTF19abanrhr as a candidate electromagnetic counterpart to the binary black hole merger GW190521. The authors argue that the observations are consistent with a kicked binary black hole interacting with the accretion disk of the active galactic nucleus AGN J124942.3 + 344929. If a real association (rather than happenstance), this has implications for the sources of LIGO/Virgo binary mergers, future prospects for electromagnetic… 
Searching for vector boson-star mergers within LIGO-Virgo intermediate-mass black-hole merger candidates
We present the first systematic search for exotic compact mergers in Advanced LIGO and Virgo events. We compare the short gravitational-wave signals GW190521, GW200220 and GW190426, and the trigger
The Gravity Collective: A Search for the Electromagnetic Counterpart to the Neutron Star–Black Hole Merger GW190814
We present optical follow-up imaging obtained with the Katzman Automatic Imaging Telescope, Las Cumbres Observatory Global Telescope Network, Nickel Telescope, Swope Telescope, and Thacher Telescope
Evidence of Large Recoil Velocity from a Black Hole Merger Signal.
The final black hole left behind after a binary black hole merger can attain a recoil velocity, or a "kick," reaching values up to 5000  km/s. This phenomenon has important implications for
Cosmology and modified gravitational wave propagation from binary black hole population models
A joint hierarchical Bayesian analysis of the binary black hole (BBH) mass function, merger rate evolution and cosmological parameters can be used to extract information on both the cosmological and
Cosmology with LIGO/Virgo dark sirens: Hubble parameter and modified gravitational wave propagation
We present a detailed study of the methodology for correlating `dark sirens' (compact binaries coalescences without electromagnetic counterpart) with galaxy catalogs. We propose several improvements
Hierarchical mergers of stellar-mass black holes and their gravitational-wave signatures
We review theoretical findings, astrophysical modeling, and current gravitational-wave evidence of hierarchical stellar-mass black-hole mergers. While most of the compact binary mergers detected by
Compact Binary Coalescences: Astrophysical Processes and Lessons Learned
On 11 February 2016, the LIGO and Virgo scientific collaborations announced the first direct detection of gravitational waves, a signal caught by the LIGO interferometers on 14 September 2015, and
A Detailed Analysis of GW190521 with Phenomenological Waveform Models
In this paper we present an extensive analysis of the GW190521 gravitational wave event with the current (fourth) generation of phenomenological waveform models for binary black hole coalescences.
A Systematic Exploration of Kilonova Candidates from Neutron Star Mergers during the Third Gravitational-wave Observing Run
We present a comprehensive analysis of 653 optical candidate counterparts reported during the third gravitational-wave (GW) observing run. Our sample concentrates on candidates from the 15 events
Binary Neutron Star Mergers in AGN Accretion Disks: Cocoon and Ejecta Shock Breakouts
Compact binary coalescences are believed to occur in accretion disks around supermassive black holes. Here we show that a putative jet launched from the merger of a binary neutron star (BNS) or a

Candidate Electromagnetic Counterpart to the Binary Black Hole Merger Gravitational-Wave Event S190521g.
TLDR
The first plausible optical electromagnetic counterpart to a (candidate) binary black hole merger in the accretion disk of an active galactic nucleus is reported, and a repeat flare in this source due to a reencountering with the disk is predicted.
Properties and Astrophysical Implications of the 150 M⊙ Binary Black Hole Merger GW190521
The gravitational-wave signal GW190521 is consistent with a binary black hole (BBH) merger source at redshift 0.8 with unusually high component masses, 85 − 14 + 21 M⊙ and 66 − 18 + 17 M⊙, compared
GW190521: A Binary Black Hole Merger with a Total Mass of 150  M_{⊙}.
TLDR
It is inferred that the primary black hole mass lies within the gap produced by (pulsational) pair-instability supernova processes, with only a 0.32% probability of being below 65  M⊙, which can be considered an intermediate mass black hole (IMBH).
Limits on Electromagnetic Counterparts of Gravitational-wave-detected Binary Black Hole Mergers
Unlike mergers of two compact objects containing a neutron star (NS), binary black hole (BBH) mergers are not accompanied by the production of tidally disrupted material and hence lack the most

Gravitational wave observations can be used to accurately measure the Hubble constant $H_0$ and could help understand the present discrepancy between constraints from Type Ia supernovae and the
GW190521 as a Highly Eccentric Black Hole Merger
The stellar-mass black hole merger GW190521 is the heaviest system discovered by LIGO/Virgo so far, with masses unexpected from stellar evolution. The system underwent precession due to its black

Pair-instability supernovae are thought to restrict the formation of black holes in the mass range ∼ 50 – 135 M ⊙ . However, black holes with masses within this “high mass gap” are expected to form
