Vector Dark Matter from Extra Dimensions
Arturo de Giorgi, Stefan Vogl
In this work, we propose a new natural dark matter candidate: Kaluza-Klein towers of vectors from extra-dimensional models. Their naturalness follows from two key feature…
Dark Photons from Red Dwarfs
Stefan Vogl, Xun-Jie Xu
Light dark photons can be produced in stellar systems and thus contribute to the stellar cooling rate. The additional cooling changes the evolution of the star and has an impact on…
Less structure on Mpc scales from decaying sterile neutrino dark matter
María Dias Astros, Lukáš Gráf, Stefan Vogl
Late decays of dark matter to a lighter, warm dark matter component are a known way to reduce the amplitude of the matter power spectrum on scales of Mpc. However, only very fe…
Neutrino transition dipole moments in light of the KM3NeT event
Alejandro Muñoz-Ovalle, Stefan Vogl
In 2023, KM3NeT observed the highest energy neutrino seen to date. The most probable estimate places the energy of the neutrino at an extreme value of 220 PeV, and energies up to 2…
Freeze-in leptogenesis with sterile neutrino self-interactions
Maria Dias Astros, Stefan Vogl
Sterile neutrinos are a simple yet compelling addition to the Standard Model. For right-handed neutrinos with masses below the electroweak scale, leptogenesis can proceed through C…
Heating the dark matter halo with dark radiation from supernovae
Stefan Vogl, Xun-Jie Xu
Supernova explosions are among the most extreme events in the Universe, making them a promising environment in which to search for the effects of light, weakly coupled new particle…
Gravity-Matter Sum Rules in models with a single extra-dimension
A. de Giorgi, S. Vogl
We prove a set of sum rules needed for KK-graviton pair production from matter in orbifolded extra-dimensional models. The sum rules can be found in full generality by considering…
Testing secret interaction with astrophysical neutrino point sources
C. Döring, S. Vogl
Recently, the IceCube collaboration observed a neutrino excess in the direction of NGC 1068 with high statistical significance. This constitutes the second detection of an astrophy…
