Not all those missing are lost: leveraging galaxy clustering in incomplete catalogs to unleash dark sirens cosmology
Riccardo Barbieri, Marios Kalomenopoulos, Matteo Tagliazucchi +2
Gravitational waves offer a unique opportunity to solve the Hubble tension. In order to do so, we have to extract as much information as possible from cross correlating gravitation…

Padé Approximants for cosmic Dispersion Measures
Marios Kalomenopoulos, Jiaming Zhuge
Fast Radio Bursts (FRBs) have become an indispensable tool for studying the ``missing baryons'', the Universe's ionisation properties, as well as the cosmological parameters. This…

Hawking Radiation from non-evaporating primordial black holes cannot enable the formation of direct collapse black holes
Jonathan Regan, Marios Kalomenopoulos, Kelly Kosmo O'Neil
The formation of supermassive black holes (SMBHs) in the early Universe is a subject of significant debate. In this study, we examine whether non-evaporating primordial black holes…
