Neutrino flavor instabilities intermediate between slow and fast
Nicolas Viaux, Lucas Johns
The neutrino flavor composition in supernovae and neutron star mergers is shaped by flavor instabilities, which are commonly classified into three types: slow (SFI), fast (FFI), an…
Non-Monotonic Rotation Imprint on Time-Integrated Neutrino Spectral Moments in a 15\, Core-Collapse Supernova Sequence
Nicolas Viaux
We study the early post-bounce neutrino signal of the published Garching rotating core-collapse supernova (CCSN) sequence consisting of non-rotating (NR), slowly rota…
An Analytic Threshold for LESA-Driven Negative ELN Flux Directions in Core-Collapse Supernovae: Derivation and Population Census
Nicolás Viaux, Lucas Johns
In core-collapse supernovae (CCSNe), deleptonization normally favors over emission. However, lepton-number emission self-sustained asymmetry (LESA) can make the ene…
Which Neutron Stars Reach the Stiffening Regime? Multimessenger Constraints on Core Sound Speed and Stellar-Mass Thresholds
Nicolás Viaux, Sebastián Mendizabal
We present a concise multimessenger inference of the neutron-star core sound-speed profile using GW170817 and three \textit{NICER} mass--radius posteriors (PSR J00300451, PSR J0…
Refining the Greisen Profile for Low-Energy Cosmic Gamma-Rays: Quantifying Deviations Across Altitudes and Zenith Angles
Constanza Valdivieso, Bárbara Gutierrez, Nicolás Viaux M +3
This study refines the Greisen formalism by comparing the classical Greisen profile and a modified Greisen profile, which incorporates an empirical correction to the shower age par…
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…
