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 more accurately the metal-dependent star formation rate is modeled, the larger the predicted excess of binary black hole mergers
Cecilia Sgalletta, Michela Mapelli, Lumen Boco +5
As the number of gravitational-wave detections grows, the merger rate of binary black holes (BBHs) can help us to constrain their formation, the properties of their progenitors, an…
The initial mass-remnant mass relation for core collapse supernovae
C. Ugolini, M. Limongi, R. Schneider +3
The first direct detection of gravitational waves in 2015 marked the beginning of a new era for the study of compact objects. Upcoming detectors, such as the Einstein Telescope, ar…
Constraining the Initial-Mass Function via Stellar Transients
Francesco Gabrielli, Lumen Boco, Giancarlo Ghirlanda +4
The stellar initial-mass function (IMF) represents a fundamental quantity in astrophysics and cosmology, describing the mass distribution of stars from low to very-high masses. It…
The cosmic rate of Pair-Instability Supernovae
Francesco Gabrielli, Andrea Lapi, Lumen Boco +8
Pair-instability supernovae (PISNe) have crucial implications for many astrophysical topics, including the search for very massive stars, the black hole mass spectrum, and galaxy c…
