Solar-System Abundances of -Nuclides Probe Collective Neutrino Oscillations in Supernovae
Alexander Friedland, Derek J. Li, Giuseppe Lucente +3
Direct evidence for collective neutrino oscillations in core-collapse supernovae remains elusive. We show that this quantum phenomenon leaves a footprint on the abundance pattern o…
Millicharged Particle Constraints from Asymptotic Giant Branch Stars
Damiano F. G. Fiorillo, Giuseppe Lucente, Jeremy Sakstein +1
We investigate the effect of millicharged particles (MCPs) with electric charge and mass on the late-stage evolution phases of low-mass stars in globular clusters.…
Enhanced Stellar Production of Weakly Interacting Slim Particles from Non-Thermal Nuclear Cascades
VÃctor Fonoll, Maurizio Giannotti, Giuseppe Lucente
Weakly interacting slim particles (WISPs) can be produced in stars through the conversion of non-thermal photons generated in nuclear reactions. Previous studies have generally tre…
Millicharged Particle Production During Late-Stage Stellar Evolution
Damiano F. G. Fiorillo, Giuseppe Lucente, Jeremy Sakstein +1
Stars are natural sources of feebly interacting particles, including putative particles with mass and electric charge . The emission of such millicharged particles (MCPs…
The Black Hole Mass Gap as a New Probe of Millicharged Particles
Damiano F. G. Fiorillo, Giuseppe Lucente, Jeremy Sakstein +2
We investigate the impact of millicharged particles (MCPs) on massive stars undergoing pulsational pair-instability supernovae and on the location of the lower edge of the black ho…
Axions at the meV Crossroads: Theory, Cosmology, Astrophysics, and Experiments
Michele Cicoli, Francesco D'Eramo, Luca Di Luzio +18
The meV mass range has emerged as a focal point in axion physics, where advances in theory, cosmology, astrophysics, and experimental techniques converge. Axions in this mass range…
