Gravitational-Wave Signals for Supernova Explosions of Three-Dimensional Progenitors

Alessandro Lella, Giuseppe Lucente, Daniel Kresse +3

Core-collapse supernovae (SNe) are sources of gravitational waves (GWs) produced by hydrodynamical instabilities and highly time-dependent anisotropies of the neutrino radiation. I…

Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory

K. Abe, S. Abe, J. Abhir +491

The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…

-process in Core-Collapse Supernovae: Imprints of General Relativistic Effects

Alexander Friedland, Derek J. Li, Giuseppe Lucente +2

The origin of a number of proton-rich isotopes in the solar system has been a long-standing puzzle. A promising explanation is the -process, which is posited to operate in the…

Flavor Equilibration of Supernova Neutrinos: Exploring the Dynamics of Slow Modes

Ian Padilla-Gay, Heng-Hao Chen, Sajad Abbar +2

Neutrinos experience collective flavor conversion in extreme astrophysical environments such as core-collapse supernovae (CCSNe). One manifestation of collective conversion is slow…

Puzzling Variation of Gamma Rays from the Sun over the Solar Cycle Revealed with Fermi-LAT

A. Acharyya, A. Adelfio, M. Ajello +100

The steady-state gamma-ray emission from the Sun is thought to consist of two emission components due to interactions with Galactic cosmic rays: (1) a hadronic disk component, and…
