Using SKAO to Understand the Clustering of Gravitational Wave Sources
Michele Bosi, Sarah Libanore, Nicola Bellomo +4
Coalescing Binary Black Holes (BBHs) trace the Large-Scale Structure (LSS) of the Universe, and their clustering properties can be extracted from Gravitational Wave (GW) data. Next…
Cosmography via stellar archaeology of low-redshift early-type galaxies from SDSS
Carlos A. Álvarez, Marcos M. Cueli, Alessandro Bressan +5
Cosmic chronometers offer a model-independent way to trace the expansion history of the Universe via the dating of passively evolving objects. This enables testing the validity of…
Semi-empirical Framework of Supermassive Black Hole Evolution: Highlighting a possible tension between Demographics and Gravitational Wave Background
Andrea Lapi, Francesco Shankar, Michele Bosi +4
The evolution of the supermassive Black Hole (BH) population across cosmic times remains a central unresolved issue in modern astrophysics, due to the many noticeable uncertainties…
StAGE: Stellar Archaeology-driven Galaxy Evolution
Michele Bosi, Andrea Lapi, Lumen Boco +10
We build a semi-empirical framework of galaxy evolution (dubbed StAGE) firmly grounded on stellar archaeology. The latter provides data-driven prescriptions that, on a population s…
