Multi-messenger prospects for black hole - neutron star mergers in the O4 and O5 runs Authors: Colombo, Alberto ; Duqué, Raphaël ; Salafia, Om Sharan ; Broekgaarden, Floor S. ; Iacovelli, Francesco ; Mancarella, Michele ; Andreoni, Igor ; Gabrielli, Francesco ; Ragosta, Fabio ; Ghirlanda, Giancarlo ; Fragos, Tassos ; Levan, Andrew J. ;…

Can we identify primordial black holes? Tidal tests for subsolar-mass gravitational-wave observations Authors: Crescimbeni, Francesco ; Franciolini, Gabriele ; Pani, Paolo ; Riotto, Antonio. Abstract: The detection of a subsolar object in a compact binary merger is regarded as one of the smoking gun signatures of a population of primordial black holes (PBHs). We critically…

The PTA Hellings and Downs correlation unmasked by symmetries Authors: Kehagias, A. ; Riotto, A. Abstract: The Hellings and Downs correlation curve describes the correlation of the timing residuals from pairs of pulsars as a function of their angular separation on the sky and is a smoking-gun signature for the detection of an isotropic stochastic…

Computing Challenges for the Einstein Telescope project Authors: S. Bagnasco, A. Bozzi, T. Fragos, A. Gonzalvez, S. Hahn, G. Hemming, L. Lavezzi, P. Laycock, G. Merino, S. Pardi, S. Schramm, A. Stahl, A. Tanasijczuk, N. Tonello, S. Vallero, J. Veitch, P. Verdier. Abstract: The discovery of gravitational waves, first observed in September 2015 following the…

The weak gravity conjecture, overcharged shells and gravitational traps Authors: A. Kehagias, K. Kokkotas, A. Riotto, J. Taskas, G. Tringas. Abstract: The Weak Gravity Conjecture (WGC) predicts that in quantum gravity there should exist overcharged states, that is states with charge larger than their mass. Extending this to large masses and charges, we are expecting…

X-ray luminosity function of high-mass X-ray binaries: Studying the signatures of different physical processes using detailed binary evolution calculations Authors: Misra, Devina ; Kovlakas, Konstantinos ; Fragos, Tassos ; Lazzarini, Margaret ; Bavera, Simone S. ; Lehmer, Bret D. ; Zezas, Andreas ; Zapartas, Emmanouil ; Xing, Zepei ; Andrews, Jeff J. ; Dotter, Aaron…

Cosmology and Astrophysics with Standard Sirens and Galaxy Catalogs in View of Future Gravitational Wave Observations Authors: N. Borghi, M. Mancarella, M. Moresco, M. Tagliazucchi, F. Iacovelli, A. Cimatti, M. Maggiore. Abstract: With the growing number of gravitational wave (GW) detections and the advent of large galaxy redshift surveys, a new era in cosmology is…

The Future of Primordial Black Holes: Open Questions and Roadmap Authors: Riotto, Antonio ; Silk, Joe. Abstract: We discuss some of the the open questions and the roadmap in the physics of primordial black holes. Black holes are the only dark matter candidate that is known to actually exit. Their conjectured primordial role is admittedly…

Román-Garza, J.  Andrews, A. Dotter, K. Kovlakas, D. Misra, P. Srivastava, K. Rocha, M. Sun, E. Zapartas. Abstract: Neutron star - black hole (NSBH) merger events…

Exploring the nature of ultra-luminous X-ray sources across stellar population ages using detailed binary evolution calculations Authors: D. Misra, K.  Kovlakas, T. Fragos, J.  Andrews, S. Bavera, E. Zapartas, Z. Xing, A. Dotter, K. Rocha, P. Srivastava, M. Sun. Abstract: Context. Ultra-luminous X-ray sources (ULXs) are sources observed to have extreme X-ray luminosities exceeding the…
