H I spin temperature in the Fermi-LAT era
Gudlaugur Johannesson, Igor Moskalenko, Seth Digel
The diffuse high-energy gamma-ray emission of the Milky Way arises from interactions of cosmic-rays (CRs) with interstellar gas and radiation field in the Galaxy. The neutral hydro…
Very Local Impact on the Spectrum of Cosmic-Ray Nuclei below 100 TeV
Mikhail Malkov, Igor Moskalenko, Patrick Diamond +1
Recent measurements of primary and secondary CR spectra, their arrival directions, and our improved knowledge of the magnetic field geometry around the heliosphere allow us to set…
All-sky Medium Energy Gamma-ray Observatory: Exploring the Extreme Multimessenger Universe
Julie McEnery, Juan Abel Barrio, Ivan Agudo +182
The All-sky Medium Energy Gamma-ray Observatory (AMEGO) is a probe class mission concept that will provide essential contributions to multimessenger astrophysics in the late 2020s…
Dark Matter Interpretation of the Fermi-LAT Observations Toward the Outer Halo of M31
Chris Karwin, Simona Murgia, Igor Moskalenko +3
An excess -ray signal toward the outer halo of M31 has recently been reported. Although other explanations are plausible, the possibility that it arises from dark matter (DM) i…
Fermi-LAT Observations of Gamma-Ray Emission Towards the Outer Halo of M31
Chris Karwin, Simona Murgia, Sheldon Campbell +1
The Andromeda Galaxy is the closest spiral galaxy to us and has been the subject of numerous studies. It harbors a massive dark matter (DM) halo which may span up to ~600 kpc acros…
The Fourth Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope -- Data Release 3
LAT collaboration, Marco Ajello, Luca Baldini +100
An incremental version of the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi-Large Area Telescope is presented. This version (4LAC-DR3) derives from the thir…
