Probing the Black Hole Metric. I. Black Hole Shadows and Binary Black-Hole Inspirals

no code implementations3 Dec 2020 Dimitrios Psaltis, Colm Talbot, Ethan Payne, Ilya Mandel

In General Relativity, the spacetimes of black holes have three fundamental properties: (i) they are the same, to lowest order in spin, as the metrics of stellar objects; (ii) they are independent of mass, when expressed in geometric units; and (iii) they are described by the Kerr metric.

Common Envelope Wind Tunnel: The Effects of Binary Mass Ratio and Implications for the Accretion-Driven Growth of LIGO Binary Black Holes

1 code implementation29 Oct 2019 Soumi De, Morgan MacLeod, Rosa Wallace Everson, Andrea Antoni, Ilya Mandel, Enrico Ramirez-Ruiz

We demonstrate that the mass and spin accrued by these black holes per unit orbital tightening are directly related to the ratio of accretion to drag coefficients.

STROOPWAFEL: Simulating rare outcomes from astrophysical populations, with application to gravitational-wave sources

1 code implementation2 May 2019 Floor S. Broekgaarden, Stephen Justham, Selma E. de Mink, Jonathan Gair, Ilya Mandel, Simon Stevenson, Jim W. Barrett, Alejandro Vigna-Gómez, Coenraad J. Neijssel

We implement the algorithm in the binary population synthesis code COMPAS, and compare the efficiency of our implementation to the standard method of Monte Carlo sampling from the birth probability distributions.
