Localizing Momentum Waves on Mazes
Tobi Ramella, Nicholas P. Warner
We examine the proposal and analysis of arXiv:2404.14477 for putting momentum waves on mazes of intersecting M2 and M5 branes by computing a family of simple examples of momentum w…
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…
Can current models predict the local black hole merger rate?
Lumen Boco, Michele Bosi, Cecilia Sgalletta +2
After four observational runs, the Ligo-Virgo-Kagra collaboration estimated a local binary black hole (BBH) merger rate density of $R_{0,\textrm{LVK}}\simeq 14-26\,\textrm{Gpc}^{-3…
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…
Cosmography via stellar archaeology of low-redshift early-type galaxies from SDSS
Carlos A. Ãlvarez, 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…
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…
