Our approach is data-driven and relies on theoretical assumptions as little as possible. [...] OpenAccess: PDF PDF (PDFA); 2018-03-1214:09 [PUBDB-2018-01459] Journal Article/Contribution to a conference proceedings et al A state-of-the-art calculation of atmospheric lepton fluxes 35th International Cosmic Ray Conference, ICRC2017, Meeting locationBexco, South Korea, 10 Jul 2017 - 20 Jul 2017 Proceedings of Science (ICRC2017), 1019 (2017) [10.3204/PUBDB-2018-01459]   Atmospheric leptons are of continuous interest for several scientific communities. At low and intermediate energies, atmospheric neutrinos are the signal for studies of fundamental neutrino properties and at high energies, they constitute the background for the characterization of the features of the astrophysical neutrino flux [...] OpenAccess: PDF PDF (PDFA); 2018-03-1214:04 [PUBDB-2018-01458] Journal Article/Contribution to a conference proceedings Winter, W. Nuclear physics aspects of relevance to the sources of UHECRs 35th International Cosmic Ray Conference, ICRC217, Meeting locationBexco, South Korea, 10 Jul 2017 - 20 Jul 2017 Proceedings of Science (ICRC2017), 559 (2017) [10.3204/PUBDB-2018-01458]   Although the accelerators of ultra-high energy cosmic rays (UHECR) are still not identified, we have new hope to constrain their properties using a multi-messenger approach. Every astrophysical environment, where UHECR nuclei are accelerated and interact with the dense photon fields, will also emit neutrinos [...] OpenAccess: PDF PDF (PDFA); 2018-03-1213:59 [PUBDB-2018-01456] Journal Article/Contribution to a conference proceedings et al Exploring potential cosmic ray accelerators with neutrinos: what do we learn by injecting nuclei in Gamma-Ray Bursts? 35th International Cosmic Ray Conference, Meeting locationBexco, South Korea, 10 Jul 2017 - 20 Jul 2017 Proceedings of Science (ICRC2017), 1064 (2027) [10.3204/PUBDB-2018-01456]   Neutrino stacking analysis constrains the paradigm that Gamma-Ray Bursts (GRBs) are the sources of the Ultra-High Energy Cosmic Rays (UHECRs). However, most of the literature has focused on a pure proton composition of UHECRs, which has been disfavored by recent composition measurements of the Pierre Auger Observatory.

Expected neutrino fluence from short Gamma-Ray Burst 170817A and off-axis angle constraints [arXiv:1712.00449] Monthly notices of the Royal Astronomical Society 476, 1191 – 1197 (2018) [10.1093/mnras/sty285]   We compute the expected neutrino fluence from SGRB 170817A, associated with the gravitational wave event GW 170817, directly based on Fermi observations in two scenarios: structured jet and off-axis (observed) top-hat jet. While the expected neutrino fluence for the structured jet case is very small, large off-axis angles imply high radiation densities in the jet, which can enhance the neutrino production efficiency.

A Multi-Component Model for the Observed Astrophysical Neutrinos [arXiv:1801.07277]   We propose a multi-component model for the observed diffuse neutrino flux, including the residual atmospheric backgrounds, a Galactic contribution (such as from cosmic ray interactions with gas), an extra-galactic contribution from pp interactions (such as from starburst galaxies) and a hard extragalatic contribution from photo-hadronic interactions at the highest energies (such as from Tidal Disruption Events or Active Galactic Nuclei). We demonstrate that this model can address the key problems of astrophysical neutrino data, such as the different observed spectral indices in the high-energy starting and through-going muon samples, a possible anisotropy due to Galactic events, the non-observation of point sources, and the constraint from the extragalatic diffuse gamma-ray background.

We compute the nuclear cascade in the jet for both BL Lac objects and flat-spectrum radio quasars (FSRQs), and in the ambient radiation zones for FSRQs as well.

J. Attenuation of TeV $\gamma$-rays by the starlight photon field of the host galaxy Monthly notices of the Royal Astronomical Society 465(3), 3767 - 3774 (2017) [10.1093/mnras/stw3032]   The absorption of TeV $\gamma$-ray photons produced in relativistic jets by surrounding soft photon fields is a long-standing problem of jet physics. In some cases, the most likely emission site close to the central black hole is ruled out because of the high opacity caused by strong optical and infrared photon sources, such as the broad-line region.
