Popcorn in the sky: Identifying primordial black holes in the gravitational-wave background
Eleni Bagui, Sébastien Clesse, Federico De Lillo +2
Primordial black holes (PBHs) are possible sources of a gravitational-wave background (GWB), detectable with the next observing runs of LIGO--Virgo--KAGRA. In case of a detection,…
Probing Cosmic Expansion and Early Universe with Einstein Telescope
Angelo Ricciardone, Mairi Sakellariadou, Archisman Ghosh +52
Over the next two decades, gravitational-wave (GW) observations are expected to evolve from a discovery-driven endeavour into a precision tool for astrophysics, cosmology, and fund…
Unbiased estimation of gravitational-wave anisotropies from noisy data
Nikolaos Kouvatsos, Alexander C. Jenkins, Arianna I. Renzini +2
One of the most exciting targets of current and future gravitational-wave observations is the angular power spectrum of the astrophysical GW background. This cumulative signal enco…
Gravitational-wave event rates as a new probe for dark matter microphysics
Markus R. Mosbech, Alexander C. Jenkins, Sownak Bose +3
We show that gravitational waves have the potential to unravel the microphysical properties of dark matter due to the dependence of the binary black hole merger rate on cosmic stru…
Cosmology with the Laser Interferometer Space Antenna
Pierre Auclair, David Bacon, Tessa Baker +177
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravita…
Probing Anisotropies of the Stochastic Gravitational Wave Background with LISA
Nicola Bartolo, Daniele Bertacca, Robert Caldwell +19
We investigate the sensitivity of the Laser Interferometer Space Antenna (LISA) to the anisotropies of the Stochastic Gravitational Wave Background (SGWB). We first discuss the mai…
Bridging the Hz gap in the gravitational-wave landscape with binary resonance
Diego Blas, Alexander C. Jenkins
Gravitational-wave (GW) astronomy is transforming our understanding of the Universe by probing phenomena invisible to electromagnetic observatories. A comprehensive exploration of…
Primordial black holes from cusp collapse on cosmic strings
Alexander C. Jenkins, Mairi Sakellariadou
Primordial black holes (PBHs) are of fundamental interest in cosmology and astrophysics, and have received much attention as a dark matter candidate and as a potential source of gr…
Probing the gravitational wave background from cosmic strings with LISA
Pierre Auclair, Jose J. Blanco-Pillado, Daniel G. Figueroa +8
Cosmic string networks offer one of the best prospects for detection of cosmological gravitational waves (GWs). The combined incoherent GW emission of a large number of string loop…
Projection effects on the observed angular spectrum of the astrophysical stochastic gravitational wave background
Daniele Bertacca, Angelo Ricciardone, Nicola Bellomo +5
The detection and characterization of the Stochastic Gravitational Wave Background (SGWB) is one of the main goals of Gravitational Wave (GW) experiments. The observed SGWB will be…
Estimating the angular power spectrum of the gravitational-wave background in the presence of shot noise
Alexander C. Jenkins, Joseph D. Romano, Mairi Sakellariadou
There has been much recent interest in studying anisotropies in the astrophysical gravitational-wave (GW) background, as these could provide us with interesting new information abo…
Shot noise in the astrophysical gravitational-wave background
Alexander C. Jenkins, Mairi Sakellariadou
We calculate the noise induced in the anisotropies of the astrophysical gravitational-wave background by finite sampling of both the galaxy distribution and the compact binary coal…
Response to Cusin et al's comment on arXiv:1810.13435
Alexander C. Jenkins, Mairi Sakellariadou, Tania Regimbau +3
We offer a brief response to the criticisms put forward by Cusin et al in arXiv:1811.03582 about our work arXiv:1810.13435 and arXiv:1806.01718, emphasising that none of these crit…
Anisotropies in the astrophysical gravitational-wave background: The impact of black hole distributions
Alexander C. Jenkins, Richard O'Shaughnessy, Mairi Sakellariadou +1
We use population inference to explore the impact that uncertainties in the distribution of binary black holes (BBH) have on the astrophysical gravitational-wave background (AGWB).…
Anisotropies in the astrophysical gravitational-wave background: Predictions for the detection of compact binaries by LIGO and Virgo
Alexander C. Jenkins, Mairi Sakellariadou, Tania Regimbau +1
We develop a detailed anisotropic model for the astrophysical gravitational-wave background, including binary mergers of two stellar-mass black holes, two neutron stars, or one of…

Alexander C. Jenkins, Mairi Sakellariadou
We develop a powerful analytical formalism for calculating the energy density of the stochastic gravitational wave background, including a full description of its anisotropies. Thi…
