A Multiwavelength Interpretation of HESS J1857+026 Emission Using the Fermi-LAT, VERITAS, and HAWC Observatories

Jordan Eagle, Yu Chen, Ramiro Torres-Escobedo +2

We present a new study on the MeV-TeV gamma-ray origin of HESS J1857+026 using data collected from the Fermi-LAT, VERITAS, and HAWC observatories. A spatial and spectral study of H…

Constraining the Photon Intensity of Extragalactic Background Light with the HAWC Observatory for the Blazar Mrk 421

R. Alfaro, C. Alvarez, A. Andrés +79

The blazar Mrk 421 exhibits rapid variability over a wide range of timescales. Spectral differences have been observed during the different emission states of Mrk 421. During the h…

GeV emission in the region of Vela: a new view of the supernova remnant

Miguel Araya, Santiago Ramírez, Diego Bueso +1

The Vela supernova remnant (SNR), G263.9-3.3, and its pulsar wind nebula (PWN), Vela X, is one of the closest such systems, and it has been studied using observations across the el…

Teleios (G305.4-2.2) -- the mystery of a perfectly shaped new Galactic supernova remnant

Miroslav D. Filipovic, Zachary J. Smeaton, Roland Kothes +35

We present the serendipitous radio-continuum discovery of a likely Galactic supernova remnant (SNR) G305.4-2.2. This object displays a remarkable circular symmetry in shape, making…

Diprotodon on the sky. The Large Galactic Supernova Remnant (SNR) G278.94+1.35

Miroslav D. Filipović, S. Lazarević, M. Araya +41

We present a re-discovery of G278.94+1.35 as possibly one of the largest known Galactic supernova remnants (SNR) - that we name Diprotodon. While previously established as a Galact…
