Probability of primordial black hole formation and its dependence on the radial profile of initial configurations
J. C. Hidalgo, A. G. Polnarev
In this paper we derive the probability of the radial profiles of spherically symmetric inhomogeneities in order to provide an improved estimation of the number density of primordi…
Limits on the speed of gravitational waves from pulsar timing
D. Baskaran, A. G. Polnarev, M. S. Pshirkov +1
In this work, analyzing the propagation of electromagnetic waves in the field of gravitational waves, we show the presence and significance of the so called surfing effect for puls…
CMB Temperature Polarization Correlation and Primordial Gravitational Waves II: Wiener Filtering and Tests Based on Monte Carlo Simulations
N. J. Miller, B. G. Keating, A. G. Polnarev
In this paper we continue our study of CMB TE cross correlation as a source of information about primordial gravitational waves. In an accompanying paper, we considered the zero mu…
CMB Temperature Polarization Correlation and Primordial Gravitational Waves
A. G. Polnarev, N. J. Miller, B. G. Keating
We examine the use of the CMB's TE cross correlation power spectrum as a complementary test to detect primordial gravitational waves (PGWs). The first method used is based on the d…
The Polarization of the Cosmic Microwave Background Due to Primordial Gravitational Waves
Brian G. Keating, Alexander G. Polnarev, Nathan J. Miller +1
We review current observational constraints on the polarization of the Cosmic Microwave Background (CMB), with a particular emphasis on detecting the signature of primordial gravit…
The tidal disruption rate in dense galactic cusps containing a supermassive binary black hole
P. B. Ivanov, A. G. Polnarev, P. Saha
We consider the problem of tidal disruption of stars in the centre of a galaxy containing a supermassive binary black hole with unequal masses. We assume that over the separation d…
