Multi-wavelength radiation models for low-luminosity GRBs, and the implications for UHECRs
Annika Rudolph, Željka Bošnjak, Andrea Palladino +2
We study the prompt phase of low-luminosity Gamma-Ray Bursts (ll-GRBs) as potential source of very-high-energy (VHE) gamma rays and Ultra-High-Energy Cosmic Rays (UHECRs). Within t…
Extragalactic magnetic field constraints from ultra-high-energy cosmic rays from local galaxies
Arjen van Vliet, Andrea Palladino, Andrew Taylor +1
We interpret the correlation between local star-forming galaxy positions and ultra-high-energy cosmic ray (UHECR) directions, recently detected by the Pierre Auger Observatory (PAO…
Neutrino telescopes and high-energy cosmic neutrinos
Andrea Palladino, Maurizio Spurio, Francesco Vissani
In this review paper, we present the main aspects of high-energy cosmic neutrino astrophysics. We begin by describing the generic expectations for cosmic neutrinos, including the e…
Modelling the spread of Covid19 in Italy using a revised version of the SIR model
Andrea Palladino, Vincenzo Nardelli, Luigi Giuseppe Atzeni +5
In this paper, we present a model to predict the spread of the Covid-19 epidemic and apply it to the specific case of Italy. We started from a simple Susceptible, Infected, Recover…
EeV Astrophysical neutrinos from FSRQs?
C. Righi, A. Palladino, F. Tavecchio +1
Flat Spectrum Radio Quasars (FSRQ) are the most powerful blazars in the gamma-ray band. Although they are supposed to be good candidates in producing high energy neutrinos, no secu…
AGN jets as the origin of UHECRs and perspectives for the detection of astrophysical source neutrinos at EeV energies
Xavier Rodrigues, Jonas Heinze, Andrea Palladino +2
We demonstrate that a population of Active Galactic Nuclei (AGN) can describe the observed spectrum of ultra-high-energy cosmic rays (UHECRs) at and above the ankle, and that the d…
Can astrophysical neutrinos trace the origin of the detected ultra-high energy cosmic rays?
Andrea Palladino, Arjen van Vliet, Walter Winter +1
Since astrophysical neutrinos are produced in the interactions of cosmic rays, identifying the origin of cosmic rays using directional correlations with neutrinos is one of the mos…
Multi-messenger interpretation of the neutrinos from TXS 0506+056
Walter Winter, Shan Gao, Xavier Rodrigues +3
We discuss possible interpretations of the neutrinos observed from the AGN blazar TXS 0506+056 in the multi-messenger and multi-wavelength context, including both the 2014-15 and 2…
The flavor composition of astrophysical neutrinos after 8 years of IceCube: an indication of neutron decay scenario?
Andrea Palladino
In this work we present an updated study of the flavor composition suggested by astrophysical neutrinos observed by IceCube. The main novelties compared to previous studies are the…
Leptohadronic blazar models applied to the 2014-15 flare of TXS 0506+056
Xavier Rodrigues, Shan Gao, Anatoli Fedynitch +2
We investigate whether the emission of neutrinos observed in 2014-15 from the direction of the blazar TXS 0506+056 can be accommodated with leptohadronic multi-wavelength models of…
IceCube Neutrinos from Hadronically Powered Gamma-Ray Galaxies
Andrea Palladino, Anatoli Fedynitch, Rasmus W. Rasmussen +1
In this work we use a multi-messenger approach to determine if the high energy diffuse neutrino flux observed by the IceCube Observatory can originate from -ray sources powered…
Introduction to neutrino astronomy
Andrea Gallo Rosso, Carlo Mascaretti, Andrea Palladino +1
This writeup is an introduction to neutrino astronomy, addressed to astronomers and written by astroparticle physicists. While the focus is on achievements and goals in neutrino as…
Interpretation of the diffuse astrophysical neutrino flux in terms of the blazar sequence
Andrea Palladino, Xavier Rodrigues, Shan Gao +1
We study if the diffuse astrophysical neutrino flux can come from blazar jets -- a subclass of Active Galactic Nuclei (AGNs) -- while it, at the same time, respects the blazar stac…
The importance of observing astrophysical tau neutrinos
Andrea Palladino, Carlo Mascaretti, Francesco Vissani
The evidence of a new population of diffuse high-energy neutrinos, obtained by IceCube, has opened a new era in the field of neutrino physics. Up to now the events detected are sti…
A Multi-Component Model for the Observed Astrophysical Neutrinos
Andrea Palladino, Walter Winter
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 interact…
On the compatibility of the IceCube results with an universal neutrino spectrum
Andrea Palladino, Carlo Mascaretti, Francesco Vissani
There is mounting evidence that the IceCube findings cannot be described simply invoking a single power-law spectrum for cosmic neutrinos. We discuss which are the minimal modifica…
A multi-component model for the IceCube neutrino events
Andrea Palladino
The IceCube neutrino telescope has observed for the first time a diffuse flux of high energy neutrinos, with a possible astrophysical origin. Up to now there are no evidence of sou…
Can BL Lac emission explain the neutrinos above 0.2 PeV?
Andrea Palladino, Francesco Vissani
Multi-messenger astronomy can help to investigate the sources of the high-energy neutrinos observed by the high-energy neutrino telescope IceCube. We consider the hypothesis that t…

On the IceCube spectral anomaly
Andrea Palladino, Maurizio Spurio, Francesco Vissani
Recently it was noted that different IceCube datasets are not consistent with the same power law spectrum of the cosmic neutrinos: this is the IceCube spectral anomaly, that sugges…
Neutrinos and γ-rays from the Galactic Center Region After H.E.S.S. Multi-TeV Measurements
Silvia Celli, Andrea Palladino, Francesco Vissani
The hypothesis of a PeVatron in the Galactic Center, emerged with the recent γ-ray measurements of H.E.S.S., motivates the search for neutrinos from this source. The effect of γ-ra…
