The question of the anomalies in the neutrino sector is gaining increasing interest. Together with the longstanding short-baseline anomalies, new anomalous results are emerging and consolidating at long baselines. This is the case of the tension observed between NOvA and T2K, which persists since 2020. We will discuss the possible role of new matter effects BSM as a possible explanation of...

Primordial black holes (PBHs) may constitute part of all the Dark Matter, and as they evaporate they should emit an all particle spectrum, including neutrinos. The recently suggested theoretical framework of "memory burden" would allow the survival until today of PBHs with masses low enough to evaporate into particles of energy at the PeV and above.

In this talk, we present our recent work on cosmic antiproton and antideuteron signatures from primordial black holes (PBHs).

Light PBHs may have formed in the early Universe and could contribute to the dark matter content of our Galaxy. Their Hawking evaporation can lead to the production of antinuclei, which propagate through the Galaxy and reach Earth as cosmic rays with fluxes peaking at... -

Light Primordial Black Holes (LPBHs) with masses in the range

$10\mathrm{g} \leq M_{\rm BH} \leq 10^{9}\mathrm{g}$, although they evaporate before Big Bang Nucleosynthesis, can play a significant role in the production of both Dark Matter and Dark Radiation. In particular, LPBHs can evaporate into light axions or axion-like particles (ALPs) with masses $m_a \lesssim \mathrm{MeV}$,... -

Magnetic monopoles arise in many beyond Standard Model scenarios, restore the symmetry of Maxwell's equations, and explain the quantization of electric charge. In this work, we explore monopole-induced oscillations of the intergalactic magnetic field (IGMF). We show that these oscillations lead to a collimating effect on the trajectories of electrically charged particles, reducing the usual...

Astrophysical jets from powerful active galactic nuclei (AGN) have recently been proposed as promising probes of dark matter (DM) in the sub-GeV mass range. AGN launch relativistic jets that accelerate cosmic rays (CRs) to very high energies, which can then interact with their surroundings and produce multiwavelength (MW) emission spanning from radio frequencies to TeV $\gamma$-rays. If DM...

Neutrinos from blazars can originate from inelastic scatterings between the protons within their jets and sub-GeV dark matter (DM) around them. I will show how this mechanism can potentially account for both the IceCube detections of neutrinos from the blazar TXS 0506+056, that are otherwise challenging for astrophysical models of its jet, and also saturate the measured diffuse astrophysical...
