MeV sterile neutrinos in low reheating temperature cosmological scenarios
Graciela Gelmini, Efunwande Osoba, Sergio Palomares-Ruiz +1
It is commonly assumed that the cosmological and astrophysical bounds on the mixings of sterile with active neutrinos are much more stringent than those obtained from laboratory me…
Model-Independent Bound on the Dark Matter Lifetime
Sergio Palomares-Ruiz
If dark matter (DM) is unstable, in order to be present today, its lifetime needs to be longer than the age of the Universe, t_U ~ 4 10^{17} s. It is usually assumed that if DM dec…
Testing MeV dark matter with neutrino detectors
Sergio Palomares-Ruiz, Silvia Pascoli
MeV particles have been advocated as Dark Matter (DM) candidates in different contexts. This hypothesis can be tested indirectly by searching for the Standard Model (SM) products o…
TeV gamma-rays from photo-disintegration/de-excitation of nuclei in Westerlund 2
Luis A. Anchordoqui, John F. Beacom, Yousaf M. Butt +4
TeV gamma-rays can result from the photo-de-excitation of PeV cosmic ray nuclei after their parents have undergone photo-disintegration in an environment of ultraviolet photons. Th…
Working Group Report on the "TeV Particle Astrophysics and Physics Beyond the Standard Model"
Ivone F. M. Albuquerque, Sergio Palomares-Ruiz, Tom Weiler
This working group focused mainly on the complementarity among particle physics and astrophysics. The analysis of data from both fields will better constrain theoretical models. Mu…
TeV gamma-rays and neutrinos from photo-disintegration of nuclei in Cygnus OB2
Luis A. Anchordoqui, John F. Beacom, Haim Goldberg +2
TeV gamma-rays may provide significant information about high energy astrophysical accelerators. Such gamma-rays can result from the photo-de-excitation of PeV nuclei after their p…
