Bayesian inference of three-dimensional gas maps: I. Galactic CO
Philipp Mertsch, Andrea Vittino
Carbon monoxide (CO) is the best tracer of Galactic molecular hydrogen (H2). Its lowest rotational emission lines are in the radio regime and thanks to Galactic rotation emission a…
Explaining cosmic ray antimatter with secondaries from old supernova remnants
Philipp Mertsch, Andrea Vittino, Subir Sarkar
Despite significant efforts over the past decade, the origin of the cosmic ray positron excess has still not been unambiguously established. A popular class of candidate sources ar…
Searching for axion-like particle decay in the near-infrared background: an updated analysis
Andrea Caputo, Andrea Vittino, Nicolao Fornengo +2
The extragalactic background light is comprised of the cumulative radiation from all galaxies across the history of the universe. The angular power spectrum of the anisotropies of…
Breaks in interstellar spectra of positrons and electrons derived from time-dependent AMS data
Andrea Vittino, Philipp Mertsch, Henning Gast +1
Until fairly recently, it was widely accepted that local cosmic ray spectra were largely featureless power laws, containing limited information on their acceleration and transport.…
The origin of Galactic cosmic rays: challenges to the standard paradigm
Stefano Gabici, Carmelo Evoli, Daniele Gaggero +5
A critical review of the standard paradigm for the origin of Galactic cosmic rays is presented. Recent measurements of local and far-away cosmic rays reveal unexpected behaviours,…
Cosmic-ray propagation with DRAGON2: II. Nuclear interactions with the interstellar gas
Carmelo Evoli, Daniele Gaggero, Andrea Vittino +3
Understanding the isotopic composition of cosmic rays (CRs) observed near Earth represents a milestone towards the identification of their origin. Local fluxes contain all the know…
Cosmic-ray transport in the heliosphere with HelioProp
Andrea Vittino, Carmelo Evoli, Daniele Gaggero
Before being detected at Earth, charged cosmic rays propagate across the Solar System and undergo interactions with the turbulent solar wind and with the heliospheric magnetic fiel…
A signature of anisotropic cosmic-ray transport in the gamma-ray sky
Silvio Sergio Cerri, Daniele Gaggero, Andrea Vittino +2
A crucial process in Galactic cosmic-ray (CR) transport is the spatial diffusion due to the interaction with the interstellar turbulent magnetic field. Usually, CR diffusion is ass…
Theoretical interpretation of Pass 8 Fermi-LAT data
Mattia Di Mauro, Silvia Manconi, Andrea Vittino +12
The flux of positrons and electrons () has been measured by the Large Area Telescope (LAT) in the energy range between 7 GeV and 2 TeV. We discuss a number of in…
Cosmic-ray propagation with DRAGON2: I. numerical solver and astrophysical ingredients
Carmelo Evoli, Daniele Gaggero, Andrea Vittino +5
We present version 2 of the DRAGON code designed for computing realistic predictions of the CR densities in the Galaxy. The code numerically solves the interstellar CR transport eq…
Unveiling the Gamma-ray Source Count Distribution Below the Fermi Detection Limit with Photon Statistics
Hannes-S. Zechlin, Alessandro Cuoco, Fiorenza Donato +2
The source-count distribution as a function of their flux, dN/dS, is one of the main quantities characterizing gamma-ray source populations. We employ statistical properties of the…
AMS-02 electrons and positrons: astrophysical interpretation and Dark Matter constraints
Mattia Di Mauro, Andrea Vittino
We present here a quantitative analysis of the recent AMS-02 data with the purpose of investigating the interplay between astrophysical sources and Dark Matter in their interpretat…
Status of cosmic-ray antideuteron searches
P. von Doetinchem, T. Aramaki, S. Boggs +24
The precise measurement of cosmic-ray antiparticles serves as important means for identifying the nature of dark matter. Recent years showed that identifying the nature of dark mat…
Dark matter vs. astrophysics in the interpretation of AMS-02 electron and positron data
Mattia Di Mauro, Fiorenza Donato, Nicolao Fornengo +1
We perform a detailed quantitative analysis of the recent AMS-02 electron and positron data. We investigate the interplay between the emission from primary astrophysical sources, n…
Review of the theoretical and experimental status of dark matter identification with cosmic-ray antideuterons
T. Aramaki, S. Boggs, S. Bufalino +24
Recent years have seen increased theoretical and experimental effort towards the first-ever detection of cosmic-ray antideuterons, in particular as an indirect signature of dark ma…
Interpretation of AMS-02 electrons and positrons data
M. Di Mauro, F. Donato, N. Fornengo +2
We perform a combined analysis of the recent AMS-02 data on electrons, positrons, electrons plus positrons and positron fraction, in a self-consistent framework where we realize a…
Anti-helium from Dark Matter annihilations
Marco Cirelli, Nicolao Fornengo, Marco Taoso +1
Galactic Dark Matter (DM) annihilations can produce cosmic-ray anti-nuclei via the nuclear coalescence of the anti-protons and anti-neutrons originated directly from the annihilati…
Constraints on particle dark matter from cosmic-ray antiprotons
N. Fornengo, L. Maccione, A. Vittino
Cosmic-ray antiprotons represent an important channel for dark matter indirect-detection studies. Current measurements of the antiproton flux at the top of the atmosphere and theor…
