Impact of Population III stars on the astrophysical gravitational-wave background
Nikolaos Kouvatsos, Mairi Sakellariadou
We probe the astrophysical gravitational-wave background resulting from compact binary coalescences, focusing on Population III binary black holes. We exploit results of state-of-t…

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…

Angular power spectrum of gravitational-wave transient sources as a probe of the large-scale structure
Yanyan Zheng, Nikolaos Kouvatsos, Jacob Golomb +3
We present a new, simulation-based inference method to compute the angular power spectrum of the distribution of foreground gravitational-wave transient events. As a first applicat…
