Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +65
The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…
Spectroscopy for asymmetric binary black hole mergers
Jahed Abedi, Collin D. Capano, Shilpa Kastha +5
We study Bayesian inference of black hole ringdown modes for simulated binary black hole signals. We consider to what extent different fundamental ringdown modes can be identified…
A gating-and-inpainting perspective on GW150914 ringdown overtone: understanding the data analysis systematics
Yi-Fan Wang, Collin D. Capano, Jahed Abedi +5
We revisit the recent debate on the evidence for an overtone in the black hole ringdown of GW150914 using an independent data-analysis pipeline. By gating and inpainting the data,…
Search for echoes on the edge of quantum black holes
Jahed Abedi
I perform a template-based search for stimulated emission of Hawking radiation (or Boltzmann echoes) by combining the gravitational wave data from 47 binary black hole merger event…
Firewall black holes and echoes from an action principle
Jahed Abedi
It is often said that there is no gravity theory based on local action principles giving rise to firewall black hole solutions. Additionally, Guo and Mathur 2022 (2205.10921) have…
Estimating False Alarm Rates of Sub-Dominant Quasi-normal Modes in GW190521
Collin D. Capano, Jahed Abedi, Shilpa Kastha +6
A major aim of gravitational wave astronomy is to test observationally the Kerr nature of black holes. The strongest such test, with minimal additional assumptions, is provided by…
GW190521: Search for Echoes due to Stimulated Hawking Radiation from Black Holes
Jahed Abedi, Luís Felipe Longo Micchi, Niayesh Afshordi
Being arguably the most massive binary black hole merger event observed to date, GW190521 deserves special attention. The exceptionally loud ringdown of this merger makes it an ide…
A multimode quasi-normal spectrum from a perturbed black hole
Collin D. Capano, Miriam Cabero, Julian Westerweck +6
When two black holes merge, the late stage of gravitational wave emission is a superposition of exponentially damped sinusoids. According to the black hole no-hair theorem, this ri…
Possibility of primordial black holes as the source of gravitational wave events in the advanced LIGO detector
E. Khalouei, H. Ghodsi, S. Rahvar +1
The analysis of gravitational Wave (GW) data from advanced LIGO provides the mass of each companion of binary black holes as the source of GWs. The mass of events corresponding to…
Quantum Black Holes in the Sky
Jahed Abedi, Niayesh Afshordi, Naritaka Oshita +1
Black Holes are possibly the most enigmatic objects in our Universe. From their detection in gravitational waves upon their mergers, to their snapshot eating at the centres of gala…
Echoes from the Abyss: A Status Update
Jahed Abedi, Niayesh Afshordi
Gravitational wave echoes provide our most direct and surprising observational window into quantum nature of black holes. Three years ago, the first search for echoes from Planck-s…
Comment on: "Low significance of evidence for black hole echoes in gravitational wave data"
Jahed Abedi, Hannah Dykaar, Niayesh Afshordi
In a recent publication (1612.00266), we demonstrated that the events in the first observing run of the Advanced LIGO gravitational wave observatory (aLIGO O1) showed tentative evi…
Echoes from the Abyss: A highly spinning black hole remnant for the binary neutron star merger GW170817
Jahed Abedi, Niayesh Afshordi
The first direct observation of a binary neutron star (BNS) merger was a watershed moment in multi-messenger astronomy. However, gravitational waves from GW170817 have only been ob…
Anomaly induced quantum correction to charged black holes; geometry and thermodynamics
Jahed Abedi, Hessamaddin Arfaei, Alek Bedroya +3
We consider the corrections due to quantum fluctuations of fields on charged black holes induced from the energy-momentum trace anomaly. Although the number of horizons stays uncha…
Echoes from the Abyss: The Holiday Edition!
Jahed Abedi, Hannah Dykaar, Niayesh Afshordi
In a recent paper (arXiv:1612.00266), we reported the results of the first search for echoes from Planck-scale modifications of general relativity near black hole event horizons us…
Echoes from the Abyss: Tentative evidence for Planck-scale structure at black hole horizons
Jahed Abedi, Hannah Dykaar, Niayesh Afshordi
In classical General Relativity (GR), an observer falling into an astrophysical black hole is not expected to experience anything dramatic as she crosses the event horizon. However…
Obstruction of black hole singularity by quantum field theory effects
Jahed Abedi, Hessamaddin Arfaei
We consider the back reaction of the energy due to quantum fluctuation of the background fields considering the trace anomaly for Schwarzschild black hole. It is shown that it will…
Fermionic greybody factors in dilaton black holes
Jahed Abedi, Hessamaddin Arfaei
In this paper the question of emission of fermions in the process of dilaton black hole evolution and its characters for different dilaton coupling constants is studied. The ma…
