Article Abstract
The next two decades are expected to open the door to the first coincident detections of electromagnetic (EM) and gravitational-wave (GW) signatures associated with massive black-hole (MBH) binaries heading for coalescence. These detections will launch a new era of multimessenger astrophysics by expanding this growing field to the low-frequency GW regime and will provide an unprecedented understanding of the evolution of MBHs and galaxies. They will also constitute fundamentally new probes of cosmology and would enable unique tests of gravity. The aim of this Living Review is to provide an introduction to this research topic by presenting a summary of key findings, physical processes and ideas pertaining to EM counterparts to MBH mergers as they are known at the time of this writing. We review current observational evidence for close MBH binaries, discuss relevant physical processes and timescales, and summarize the possible EM counterparts to GWs in the precursor, coalescence, and afterglow stages of a MBH merger. We also describe open questions and discuss future prospects in this dynamic and quick-paced research area.

A dormant overmassive black hole in the early Universe.
Nature

Recent observations have found a large number of supermassive black holes already in place in the first few hundred million years after the Big Bang, many of which seem to be overmassive relative to their host galaxy stellar mass when compared with local relation. Several different models have been proposed to explain these findings, ranging from heavy seeds to light seeds experiencing bursts of high accretion rate. Yet, current datasets are unable to differentiate between these various scenarios.

The most massive black holes in our Universe form binaries at the centre of merging galaxies. The recent evidence for a gravitational-wave (GW) background from pulsar timing may constitute the first observation that these supermassive black-hole binaries (SMBHBs) merge. Yet, the most massive SMBHBs are out of reach of interferometric GW detectors and are exceedingly difficult to resolve individually with pulsar timing.

We apply a formulation of Einstein's general relativity with only cubic interactions for deriving the metric of a Schwarzschild black hole to all orders in perturbation theory. This cubic interactions formulation coupled to effective worldline action of a massive point particle allows to derive a recursion relation for the form factors of the off-shell graviton emission current. The unique solution to the recursion relation leads to the Schwarzschild black-hole solution in four dimensions.

Article Synopsis
- The article presents a new gravitational Compton amplitude for rotating Kerr black holes applicable to any quantum spin, from zero to infinity.
- It utilizes concepts from higher-spin quantum field theory, such as gauge invariance, to derive classical amplitudes with respect to the spin vector.
- The study emphasizes using a chiral-field approach for clarity in degrees of freedom and simplifies interactions, allowing for comparisons with existing general-relativity results up to eighth order in spin.
Black holes regulate cool gas accretion in massive galaxies.
Nature
August 2024
Kavli Institute for Astronomy and Astrophysics, Peking University, Beijing, China.
Article Synopsis
- Almost all massive galaxies have supermassive black holes (BHs) at their centers, which influence galaxy behavior, particularly star formation.
- Recent studies indicate that the relationship between BH activity and star formation is complex, with some galaxies showing no decrease in gas or star formation despite having active BHs.
- Research analysis reveals a strong correlation between the mass of atomic hydrogen (HI) gas and BH mass, suggesting that BHs play a key role in regulating galaxy gas content and potentially affecting star formation.
