The impact of mass-transfer physics on the observable properties of field binary black hole populations [PDF]

open access: yesAstronomy & Astrophysics, 2020
We study the impact of mass-transfer physics on the observable properties of binary black hole populations that formed through isolated binary evolution. We used the POSYDON framework to combine detailed MESA binary simulations with the COSMIC population

A Detailed View of Low-frequency Quasi-periodic Oscillation in the Broadband 0.2–200 keV with Insight-HXMT and NICER

open access: yesThe Astrophysical Journal, 2023
We report the X-ray timing results of the black hole candidate MAXI J1820+070 during its 2018 outburst using the Hard X-ray Modulation Telescope (Insight-HXMT) and Neutron Star Interior Composition Explorer Mission (NICER) observations.

Gravitational Collider Physics via Pulsar–Black Hole Binaries [PDF]

open access: yesAstrophysical Journal, 2020
We propose to use pulsar–black hole binaries as a probe of gravitational collider physics. Induced by the gravitation of the pulsar, the atomic transitions of the boson cloud around the black hole backreact on the orbital motion.

UV–Optical Disk Reverberation Lags despite a Faint X-Ray Corona in the Active Galactic Nucleus Mrk 335

open access: yesThe Astrophysical Journal, 2023
 We present the first results from a 100-day Swift, NICER, and ground-based X-ray–UV–optical reverberation mapping campaign of the Narrow-line Seyfert 1 Mrk 335, when it was in an unprecedented low X-ray flux state.

Critical point in the phase diagram of primordial quark-gluon matter from black hole physics [PDF]

open access: yes, 2017
Strongly interacting matter undergoes a crossover phase transition at high temperatures $T\ensuremath{\sim}{10}^{12}\text{ }\text{ }\mathrm{K}$ and zero net-baryon density.

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 ...

Burns space and holography

open access: yesJournal of High Energy Physics, 2023
We elaborate on various aspects of our top-down celestial holographic duality wherein the semiclassical bulk spacetime is a 4d asymptotically flat, self-dual Kähler geometry known as Burns space.

Minimum Length Effects in Black Hole Physics [PDF]

open access: yes, 2014
We review the main consequences of the possible existence of a minimum measurable length, of the order of the Planck scale, on quantum effects occurring in black hole physics.

Carrollian physics at the black hole horizon [PDF]

open access: yesClassical and quantum gravity, 2019
We show that the geometry of a black hole horizon can be described as a Carrollian geometry emerging from an ultra-relativistic limit where the near-horizon radial coordinate plays the role of a virtual velocity of light tending to zero.

Sharp Signals of Boson Clouds in Black Hole Binary Inspirals. [PDF]

open access: yesPhysical Review Letters, 2022
Gravitational waves (GWs) are an exciting new probe of physics beyond the standard models of gravity and particle physics. One interesting possibility is provided by the so-called "gravitational atom," wherein a superradiant instability spontaneously ...
