Discovery of TeV -ray emission from the neighbourhood of the supernova remnant G24.7+0.6 by MAGIC
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +151
SNR G24.7+0.6 is a 9.5 kyrs radio and -ray supernova remnant evolving in a dense medium. In the GeV regime, SNR G24.7+0.6 (3FHL\,J1834.1--0706e/FGES\,J1834.1--0706) shows a hard…
Unresolved Gamma-Ray Sky through its Angular Power Spectrum
M. Ackermann, M. Ajello, L. Baldini +107
The gamma-ray sky has been observed with unprecedented accuracy in the last decade by the Fermi large area telescope (LAT), allowing us to resolve and understand the high-energy Un…
Theoretically motivated search and detection of non-thermal pulsations from PSRs J1747-2958, J2021+3651, and J1826-1256
Jian Li, Diego F. Torres, Francesco Coti Zelati +3
Based on a theoretical selection of pulsars as candidates for detection at X-ray energies, we present an analysis of archival X-ray observations done with Chandra and XMM-Newton of…
Ultrahigh-Energy Cosmic Ray Composition from the Distribution of Arrival Directions
Rita C. dos Anjos, Jorge F. Soriano, Luis A. Anchordoqui +8
The sources of ultrahigh-energy cosmic rays (UHECRs) have been difficult to catch. It was recently pointed out that while sources of UHECR protons exhibit anisotropy patterns that…
Discovery and characterization of superefficiency in pulsar wind nebulae
Diego F. Torres, Tingting Lin
We numerically study the radiative properties of the reverberation phase of pulsar wind nebulae. Reverberation brings a significant evolution in a short period of time. We show tha…
VERITAS and Fermi-LAT observations of new HAWC sources
VERITAS Collaboration, A. U. Abeysekara, A. Archer +280
The HAWC (High Altitude Water Cherenkov) collaboration recently published their 2HWC catalog, listing 39 very high energy (VHE; >100~GeV) gamma-ray sources based on 507 days of obs…
