Quiescent and active galactic nuclei as factories of merging compact objects in the era of gravitational-wave astronomy
read the original abstract
Galactic nuclei harbouring a central supermassive black hole (SMBH), possibly surrounded by a dense nuclear cluster (NC), represent extreme environments which house a complex interplay of many physical processes that uniquely affect stellar formation, evolution, and dynamics. The discovery of gravitational waves (GW) emitted by merging black holes (BHs) and neutron stars (NSs), funnelled a huge amount of work focused on understanding how compact object binaries (COBs) can pair-up and merge together. Here, we review from a theoretical standpoint how different mechanisms concur to the formation, evolution, and merger of COBs around quiescent SMBHs and active galactic nuclei (AGNs), summarizing the main predictions for current and future (GW) detections and outlining the possible features that can clearly mark a galactic nuclei origin.

Constraints on Line-of-Sight Acceleration from O1-O4
All gravitational-wave binaries analyzed through O4a are consistent with zero line-of-sight acceleration, measured with a new time-domain Doppler method applicable to any waveform model.

Orbital evolution of asymmetric binaries within accreting environments
Disk-induced dissipation drives rapid orbital plane alignment followed by slower eccentricity damping in extreme mass-ratio inspirals, with relativistic effects producing accumulating deviations from Keplerian orbits ...

Binary disruptions driven by massive disks around massive black holes
Disk torques can drive stellar binaries around a massive black hole to tidal disruption, and the Milky Way's young stellar disk likely caused ~10^2 such events ~5 Myr ago.

Constraints on Line-of-Sight Acceleration from O1-O4
All known compact binary mergers show line-of-sight accelerations consistent with zero under a new time-domain Doppler-shift model, with current detectors only sensitive to high-acceleration scenarios.

GW231123: A Possible Primordial Black Hole Origin
GW231123's masses and high spins are consistent with primordial black holes that accreted mass and angular momentum in the early universe within the standard PBH framework.

The Chirp-Mass Ladder: A New Rung Emerges
GWTC-5 chirp-mass peaks form a ~1.9-spaced ladder with a new ~19 M⊙ rung matching predicted 2G+3G mergers, unifying prior 1G+2G spin-transition groups under one hierarchical scenario.

The Chirp-Mass Ladder: A New Rung Emerges
The chirp-mass distribution of GW-detected binary black holes shows a ladder of peaks doubling in mass, with a new intermediate peak at 19 solar masses confirming a prior prediction from the hierarchical merger model.

The Hierarchical Merger Scenario for GW231123
GW231123 is claimed to be a 2G+2G hierarchical merger, but only under the NRSur7dq4 waveform; the conclusion flips with IMRPhenomXO4a.

January Food Benchmark (JFB): A Public Benchmark Dataset and Evaluation Suite for Multimodal Food Analysis
The abstract promises a food-image benchmark and a winning model, but the manuscript pages contain only a different paper on primordial black holes, leaving every benchmark claim unsubstantiated.
