Explaining nonlinearities in black hole ringdowns from symmetries
Explaining nonlinearities in black hole ringdowns from symmetries Authors: Kehagias, Alex ; Perrone, Davide; Riotto, Antonio ; Riva, Francesco. Abstract: It has been recently pointed out that nonlinear effects are necessary to model the ringdown stage of the gravitational waveform produced by the merger of two black holes giving rise to a remnant Kerr black… -
Detection and estimation of the cosmic dipole with the einstein telescope and cosmic explorer
Detection and estimation of the cosmic dipole with the einstein telescope and cosmic explorer Authors: S. Mastrogiovanni, C. Bonvin, G. Cusin, S. Foffa. Abstract: One of the open issues of the standard cosmological model is the value of the cosmic dipole measured from the Cosmic Microwave Background (CMB), as well as from the number count… -
Heavy Primordial Black Holes from Strongly Clustered Light Black Holes
Heavy Primordial Black Holes from Strongly Clustered Light Black Holes Authors: De Luca, Valerio ; Franciolini, Gabriele ; Riotto, Antonio. Abstract: We show that heavy primordial black holes may originate from much lighter ones if the latter are strongly clustered at the time of their formation. While this population is subject to the usual constraints… -
Merging binary black holes formed through double-core evolution
Merging binary black holes formed through double-core evolution Authors: Qin, Y.; Hu, R. -C.; Meynet, G.; Wang, Y. Z.; Zhu, J. -P.; Song, H. F.; Shu, X. W.; Wu, S. C. (2023) Abstract: To date, various formation channels of merging events have been heavily explored with the detection of nearly 100 double black hole (BH)… -
SCATTER: A New Common Envelope Formalism
SCATTER: A New Common Envelope Formalism Authors: Di Stefano, Rosanne ; Kruckow, Matthias U. ; Gao, Yan ; Neunteufel, Patrick G. ; Kobayashi, Chiaki. Abstract: One of the most mysterious astrophysical states is the common envelope (CE) phase of binary evolution, in which two stars are enshrouded by the envelope shed by one of them.… -
High-redshift JWST Observations and Primordial Non-Gaussianity
High-redshift JWST Observations and Primordial Non-Gaussianity Authors: Biagetti, Matteo; Franciolini, Gabriele; Riotto, Antonio. Abstract: Several bright and massive galaxy candidates at high redshifts have been recently observed by the James Webb Space Telescope. Such early massive galaxies seem difficult to reconcile with standard Λ cold dark matter model predictions. We discuss under which circumstances such… -

Forecasting the detection capabilities of third-generation gravitational-wave detectors using GWFAST
Forecasting the detection capabilities of third-generation gravitational-wave detectors using GWFAST Authors: Iacovelli, Francesco; Mancarella, Michele; Foffa, Stefano; Maggiore, Michele (2022) Abstract: GWFAST is a novel Fisher-matrix code for gravitational-wave studies, tuned toward third-generation gravitational-wave detectors such as Einstein Telescope and Cosmic Explorer. The code is used to perform a comprehensive study of the capabilities of… -
