GW241011 and GW241110: Exploring Binary Formation and Fundamental Physics with Asymmetric, High-spin Black Hole Coalescences [PDF]

open access: yesAstrophysical Journal Letters
We report the observation of gravitational waves from two binary black hole coalescences during the fourth observing run of the LIGO–Virgo–KAGRA detector network, GW241011 and GW241110.

Nonquasinormal Modes and Black Hole Physics [PDF]

open access: yesPhysical Review Letters, 2004
The near-horizon geometry of a large class of extremal and near-extremal black holes in string and M theory contains three-dimensional asymptotically anti-de Sitter space. Motivated by this structure, we are led naturally to a discrete set of complex frequencies defined in terms of the monodromy at the inner and outer horizons of the black hole.

Quantum vortex instability and black hole superradiance

open access: yesPhysical Review Research, 2022
Vortices and black holes set the scene for many interesting dynamical processes in physics. Here, we study the dynamical instability of quantized vortices and rotational superradiance around rotating black holes, illustrating in the process that the same

No ensemble averaging below the black hole threshold [PDF]

open access: yesJournal of High Energy Physics, 2022
In the AdS/CFT correspondence, amplitudes associated to connected bulk manifolds with disconnected boundaries have presented a longstanding mystery. A possible interpretation is that they reflect the effects of averaging over an ensemble of boundary ...

Black hole spectroscopy: from theory to experiment [PDF]

open access: yesClassical and quantum gravity
The ‘ringdown’ radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes and comparing them with gravitational-wave (GW) data from compact binary ...

Habemus superstratum! A constructive proof of the existence of superstrata [PDF]

open access: yes, 2015
We construct the first example of a superstratum: a class of smooth horizonless supergravity solutions that are parameterized by arbitrary continuous functions of (at least) two variables and have the same charges as the supersymmetric D1-D5-P black hole.

The role of electron heating physics in images and variability of the Galactic Centre black hole Sagittarius A* [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
The accretion flow around the Galactic Center black hole Sagittarius A* (Sgr A*) is expected to have an electron temperature that is distinct from the ion temperature, due to weak Coulomb coupling in the low-density plasma.

Modeling Reconstructed Images of Jets Launched by SANE Super-Eddington Accretion Flows around SMBHs with the ngEHT

open access: yesGalaxies, 2022
Tidal disruption events (TDEs) around supermassive black holes (SMBHs) are a potential laboratory to study super-Eddington accretion disks and sometimes result in powerful jets or outflows which may shine in the radio and sub-millimeter bands.
