Very high energy gamma-ray emission beyond 10 TeV from GRB 221009A

Zhen Cao, F. Aharonian, Q. An +276

The highest energy gamma-rays from gamma-ray bursts (GRBs) have important implications for their radiation mechanism. Here we report for the first time the detection of gamma-rays…

HAWC Study of the Ultra-High-Energy Spectrum of MGRO J1908+06

HAWC Collaboration, A. Albert, R. Alfaro +97

We report TeV gamma-ray observations of the ultra-high-energy source MGRO J1908+06 using data from the High Altitude Water Cherenkov (HAWC) Observatory. This source is one of the h…

Multiple Galactic Sources with Emission Above 56 TeV Detected by HAWC

HAWC Collaboration, A. U. Abeysekara, A. Albert +99

We present the first catalog of gamma-ray sources emitting above 56 and 100 TeV with data from the High Altitude Water Cherenkov (HAWC) Observatory, a wide field-of-view observator…

Multiwavelength Investigation of Pulsar Wind Nebula DA 495 with HAWC, VERITAS, and NuSTAR

A. Coerver, P. Wilcox, H. Zhang +10

Pulsar Wind Nebula (PWN) DA 495 (G65.7+1.2) was detected in TeV gamma-rays by the High Altitude Water Cherenkov Observatory (HAWC) in 2017 (2HWC J1953+294). Follow-up observations…

Extended gamma-ray sources around pulsars constrain the origin of the positron flux at Earth

A. U. Abeysekara, A. Albert, R. Alfaro +113

The unexpectedly high flux of cosmic ray positrons detected at Earth may originate from nearby astrophysical sources, dark matter, or unknown processes of cosmic-ray secondary prod…

Effect of the diffusion parameters on the observed gamma-ray spectrum of sources and their contribution to the local all-electron spectrum: the EDGE code

R. López-Coto, J. Hahn, S. BenZvi +5

The positron excess measured by PAMELA and AMS can only be explained if there is one or several sources injecting them. Moreover, at the highest energies, it requires the presence…
