Context. Fermi/LAT observations of star-forming galaxies in the∼0.1-100 GeV range have made possible a first population study . Evidence was found for a correlation between -ray luminosity and tracers of the star formation activity. Studying galactic cosmic rays (CRs) in various global conditions can yield information about their origin and transport in the interstellar medi um (ISM). Aims. This work addresses the question of the scaling laws that can be expected for the interstellar -ray…

Gamma rays as probes of cosmic-ray propagation and interactions in galaxies
Continuum gamma-ray emission produced by interactions of cosmic rays with interstellar matter and radiation fields is a probe of non-thermal particle populations in galaxies. After decades of
Prospects of newly detecting nearby star-forming galaxies by the Cherenkov Telescope Array
Prospects of the Cherenkov Telescope Array (CTA) for the study of very high energy gammaray emission from nearby star-forming galaxies are investigated. In the previous work, we constructed a model
Cosmic rays across the star-forming galaxy sequence – I. Cosmic ray pressures and calorimetry
In the Milky Way, cosmic rays (CRs) are dynamically important in the interstellar medium, contribute to hydrostatic balance, and may help regulate star formation. However, we know far less about the
Observations of M31 and M33 with the Fermi Large Area Telescope: A Galactic Center Excess in Andromeda?
The Fermi Large Area Telescope (LAT) has opened the way for comparative studies of cosmic rays (CRs) and high-energy objects in the Milky Way (MW) and in other, external, star-forming galaxies. Using
Deep view of the Large Magellanic Cloud with six years of Fermi -LAT observations
The nearby Large Magellanic Cloud (LMC) provides a rare opportunity of a spatially resolved view of an external star-forming galaxy in gamma-rays. The LMC was detected at 0.1-100GeV as an extended
Cosmic rays and non-thermal emission in simulated galaxies – II. γ-ray maps, spectra, and the far-infrared–γ-ray relation
The γ-ray emission of star-forming (SF) galaxies is attributed to hadronic interactions of cosmic ray (CR) protons with the interstellar gas and contributions from CR electrons via bremsstrahlung and
The Large Magellanic Cloud with the Cherenkov Telescope Array
The Large Magellanic Cloud (LMC) is a spiral galaxy, satellite of the Milky way with a high star formation activity. It represents a unique laboratory for studying an extended and spatially resolved
Theoretical predictions for dark matter detection in dwarf irregular galaxies with gamma rays
We investigate dwarf irregular(dIrr) galaxies as a new category of targets for indirect Dark Matter(DM) searches with gamma-rays. In the framework of point-like analysis, dwarf spheroidal(dSph)
Nonthermal particles and photons in starburst regions and superbubbles
Starforming factories in galaxies produce compact clusters and loose associations of young massive stars. Fast radiation-driven winds and supernovae input their huge kinetic power into the
Breaking the radio – gamma-ray connection in Arp 220
Recent analyses of the gamma-ray spectrum from the ultra-luminous infrared galaxy Arp 220 have revealed a discrepancy in the cosmic ray energy injection rates derived from the gamma-rays versus the


Diffuse Gamma Rays from Local Group Galaxies
Diffuse γ-ray radiation in galaxies is produced by cosmic-ray interactions with the interstellar medium. With the completion of EGRET observations, the only extragalactic object from which there has
A connection between star formation activity and cosmic rays in the starburst galaxy M82
A cosmic-ray density of 250 eV cm-3 in the starburst core, which is about 500 times the average Galactic density is determined, and suggests that supernovae and massive-star winds are the dominant accelerators.

How cosmic rays sample the multi-phase interstellar medium (ISM) in starburst galaxies has important implications for many science goals, including evaluating the cosmic ray calorimeter model for
Fermi large area telescope observations of local group galaxies: detection of M 31 and search for M 33
Cosmic rays (CRs) can be studied through the galaxy-wide gamma-ray emission that they generate when propagating in the interstellar medium. The comparison of the diffuse signals from different
