The impact of stellar binaries and star cluster dynamics on pair-instability supernovae
Francesco Gabrielli, Cristiano Ugolini, Lavinia Paiella +12
Pair-instability supernovae (PISNe) are among the most luminous transients in the Universe. However, they have never been confidently observed. Solving this puzzle would have key i…
The impact of envelope binding energies on the merger rate density of binary compact objects
Cecilia Sgalletta, Guglielmo Costa, Giuliano Iorio +8
The common envelope (CE) phase plays a key role in the formation of binary compact object systems. Its final outcome strongly depends on the envelope binding energy, but this quant…
Assessing Performance and Porting Strategies for Gravitational -Body Simulations on the RISC-V-Based Tenstorrent Wormhole\textsuperscript{\texttrademark}
Jenny Lynn Almerol, Elisabetta Boella, Mario Spera +1
While RISC-V-based accelerators were initially designed with artificial intelligence applications in mind, they are increasingly being recognized as promising platforms for high pe…
Accelerating Gravitational -Body Simulations Using the RISC-V-Based Tenstorrent Wormhole
Jenny Lynn Almerol, Elisabetta Boella, Mario Spera +1
Although originally developed primarily for artificial intelligence workloads, RISC-V-based accelerators are also emerging as attractive platforms for high-performance scientific c…
Assembling GW231123 in star clusters through the combination of stellar binary evolution and hierarchical mergers
Lavinia Paiella, Cristiano Ugolini, Mario Spera +2
GW231123 is the most massive binary black hole (BBH) merger detected to date by the LIGO-Virgo-KAGRA collaboration. With at least one black hole (BH) in the upper-mass gap and both…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
