JWST observations of SN 2024abup: First Detection of CO in a broad-lined Type Ic Supernova and Constraints on r-process Nucleosynthesis
Manisha Shrestha, Lindsey A. Kwok, David J. Sand +42
SN 2024abup is a nearby broad-lined Type Ic supernova (SN Ic-bl) in NGC 0681 at a distance of 23.3 \pm 1.6 Mpc. As energetic explosions of massive stars, SNe Ic-bl are considered a…
Prospects for optical detections from binary neutron star mergers with the next-generation multi-messenger observatories
E. Loffredo, N. Hazra, U. Dupletsa +13
Next-generation gravitational wave (GW) observatories, such as the Einstein Telescope (ET) and Cosmic Explorer, will observe binary neutron star (BNS) mergers across cosmic history…
Ni production in long-lived binary neutron star merger remnants
Maximilian Jacobi, Fabio Magistrelli, Eleonora Loffredo +5
We investigate the nucleosynthesis and kilonova emission based on numerical-relativity binary neutron star merger simulations that incorporate a two-moment neutrino-transport schem…
Modeling the emission lines from r-process elements in Supernova nebulae
Giacomo Ricigliano, Kenta Hotokezaka, Almudena Arcones
The origin of heavy r-process elements in the universe is still a matter of great debate, with a confirmed scenario being neutron star (NS) mergers. Additional relevant sites could…
