Progenitors and companions of stripped-envelope supernovae Authors: E. Zapartas, O. Fox , T. Fragos,  M. Renzo,  J. Andrews,  S. S. Bavera,  A. Dotter, M. Drout, S. van Dyk, D.  Milisavljevic,  K. Kovlakas, D. Misra, K. Rocha, N. Smith,  B. Williams, Z. Xing. Abstract: In this poster, using the POSYDON code, we present results on binary…

Dynamical tides in binaries: Inconsistencies in the implementation of Zahn's prescription Authors: L. Sciarini,  S. Ekström, P. Eggenberger, G. Meynet,  T. Fragos,  H. F. Song. Abstract: Binary evolution codes are essential tools to help in understanding the evolution of binary systems. They contain a great deal of physics, for example stellar evolution, stellar interactions, mass…

Detecting the Undetected: Overcoming Biases in Gravitational-wave Population Studies Authors: R. Raikman, S. Bavera, T. Fragos. Abstract: In the flourishing field of gravitational-wave astronomy, accurately inferring binary black hole merger formation channels is paramount. The Bayesian hierarchical model selection analysis offers a promising methodology (see, e.g., "One Channel to Rule Them All"). However, recently, Cheng…

Sign of non-Gaussianity and the primordial black holes abundance Authors: H. Firouzjahi, A. Riotto. Abstract: The abundance of primordial black holes changes in the presence of local non-Gaussianity. A positive nonlinear parameter fNL increases the abundance while a negative one reduces it. We show that in nonattractor single-field models of inflation which enhance the curvature…

BinCodex: a common output format for binary population synthesis Authors: Valli, Ruggero ; Graziani, Luca ; the LISA Synthetic UCB Catalogue Group. Abstract: This document describes BinCodex, a common format for the output of binary population synthesis (BPS) codes agreed upon by the members of the LISA Synthetic UCB Catalogue Group. The goal of the…

Combining chirp mass, luminosity distance, and sky localization from gravitational wave events to detect the cosmic dipole Authors: N. Grimm, M. Pijnenburg, S. Mastrogiovanni, C .Bonvin, S. Foffa, G. Cusin. Abstract: A key test of the isotropy of the Universe on large scales consists in comparing the dipole in the cosmic microwave background (CMB) temperature…

Nuclear physics constraints from binary neutron star mergers in the Einstein Telescope era Authors: Francesco Iacovelli, Michele Mancarella, Chiranjib Mondal, Anna Puecher, Tim Dietrich, Francesca Gulminelli, Michele Maggiore, and Micaela Oertel. Abstract: The next generation of ground-based gravitational-wave detectors, Einstein Telescope (ET) and Cosmic Explorer (CE), present a unique opportunity to put constraints on dense…

Searching for primordial black holes with the Einstein Telescope: Impact of design and systematics Authors: Gabriele Franciolini, Francesco Iacovelli, Michele Mancarella, Michele Maggiore, Paolo Pani, and Antonio Riotto. Abstract: Primordial black holes (PBHs) have recently attracted much attention, as they may explain some of the LIGO/Virgo/KAGRA observations and significantly contribute to the dark matter in…

Science with the Einstein Telescope: a comparison of different designs Authors: Marica Branchesi, Michele Maggiore, David Alonso, Charles Badger, Biswajit Banerjee, Freija Beirnaert, Enis Belgacem, Swetha Bhagwat, Guillaume Boileau, Ssohrab Borhanian. Abstract: The Einstein Telescope (ET), the European project for a third-generation gravitational-wave detector, has a reference configuration based on a triangular shape consisting of…
