Voyager 1 Data Reveals Signatures of the Local Gas and Cosmic-Ray Source Distributions
Troy A. Porter, Igor V. Moskalenko, Alan C. Cummings +1
We investigate the effects of the nearby interstellar medium (ISM) on the locally measured cosmic-ray (CR) spectra. Using the GALPROP code we explore how variations in the local ga…
Combined dark matter search towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS
LAT Collaboration, S. Abdollahi, L. Baldini +586
Dwarf spheroidal galaxies (dSphs) are excellent targets for indirect dark matter (DM) searches using gamma-ray telescopes because they are thought to have high DM content and a low…
Puzzling Variation of Gamma Rays from the Sun over the Solar Cycle Revealed with Fermi-LAT
A. Acharyya, A. Adelfio, M. Ajello +100
The steady-state gamma-ray emission from the Sun is thought to consist of two emission components due to interactions with Galactic cosmic rays: (1) a hadronic disk component, and…
Fermi detection of gamma-ray Emission from the Hot Coronae of Radio-quiet Active Galactic Nuclei
Jun-Rong Liu, Jian-Min Wang, Fermi-LAT Collaboration
Relativistic jets around supermassive black holes (SMBHs) are well-known powerful -ray emitters. In absence of the jets in radio-quiet active galactic nuclei (AGNs), how the SM…
A Systematic Search for MeV-GeV Pulsar Wind Nebulae without Gamma-ray Detected Pulsars
Jordan Eagle, Daniel Castro, Wei Zhang +3
An increasing number of pulsar wind nebulae (PWNe) are being identified in the TeV band by ground-based Imaging Air Cherenkov Telescopes such that they constitute the dominant sour…
Cosmic-ray and Interstellar Gas Properties in the Solar Neighborhood Revealed by Diffuse Gamma Rays
Tsunefumi Mizuno, Katsuhiro Hayashi, Hinako Ochi +3
To investigate the interstellar medium (ISM) and Galactic cosmic rays (CRs) in the solar neighborhood, we analyzed -ray data by Fermi Large Area Telescope (LAT) for five nearby…
