Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory
K. Abe, S. Abe, J. Abhir +491
The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…
Grammage of cosmic rays in the proximity of supernova remnants embedded in a partially ionized medium

We investigate the damping of Alfvén waves generated by the cosmic ray resonant streaming instability in the context of the cosmic ray escape and propagation in the proximity of s…
The Second Radio Synchrotron Background Workshop: Conference Summary and Report
J. Singal, N. Fornengo, M. Regis +24
We summarize the second radio synchrotron background workshop, which took place June 15-17, 2022 in Barolo, Italy. This meeting was convened because available measurements of the d…
Non-linear acceleration at supernova remnant shocks and the hardening in the cosmic ray spectrum
S. Recchia, S. Gabici
In the last few years several experiments have shown that the cosmic ray spectrum below the knee is not a perfect power-law. In particular, the proton and helium spectra show a spe…
Multimessenger Search for Sources of Gravitational Waves and High-Energy Neutrinos: Results for Initial LIGO-Virgo and IceCube
The IceCube Collaboration, The LIGO Scientific Collaboration, The Virgo Collaboration +1185
We report the results of a multimessenger search for coincident signals from the LIGO and Virgo gravitational-wave observatories and the partially completed IceCube high-energy neu…
Cosmic ray driven winds in the Galactic environment and the cosmic ray spectrum
S. Recchia, P. Blasi, G. Morlino
Cosmic Rays escaping the Galaxy exert a force on the interstellar medium directed away from the Galactic disk. If this force is larger than the gravitational pull due to the mass e…
A local fading accelerator and the origin of TeV cosmic ray electrons
S. Recchia, S. Gabici, F. A. Aharonian +1
The total cosmic ray electron spectrum (electrons plus positrons) exhibits a break at a particle energy of and extends without any attenuation up to $\rm \sim 20~ T…
Can a cosmic ray carrot explain the ionization level in diffuse molecular clouds?
S. Recchia, V. H. M. Phan, S. Biswas +1
Low energy cosmic rays are the major ionization agents of molecular clouds. However, it has been shown that, if the cosmic ray spectrum measured by Voyager 1 is representative of t…
Cosmic ray driven Galactic winds
S. Recchia, P. Blasi, G. Morlino
The escape of cosmic rays from the Galaxy leads to a gradient in the cosmic ray pressure that acts as a force on the background plasma, in the direction opposite to the gravitation…

Dust-driven streaming instability and magnetic field amplification downstream of supernova remnant shocks
S. Gabici, J. C. Raymond, A. Ciardi +3
The acceleration of cosmic rays up to PeV energies at supernova remnant shocks requires an amplification of the ambient magnetic field. The amplification mechanism must operate ups…
