Galactic Gamma-Ray Diffuse Emission at TeV energies with HAWC Data

Ruben Alfaro, Carlos A. Vargas Álvarez, J. C. Arteaga‐Velázquez, K. P. Arunbabu et autres

The Galactic gamma-ray diffuse emission (GDE) is emitted by cosmic rays (CRs), ultra-relativistic protons and electrons, interacting with gas and electromagnetic radiation fields in the interstellar medium. Here we present the analysis of TeV diffuse emission from a region of the Galactic …

A Contribution of the HAWC Observatory to the TeV era in the High Energy Gamma-Ray Astrophysics: The case of the TeV-Halos

Ramiro Torres-Escobedo, H. Zhou, E. De la Fuente, A. U. Abeysekara et autres

We present a short overview of the TeV-Halos objects as a discovery and a relevant contribution of the High Altitude Water Čerenkov (HAWC) observatory to TeV astrophysics. We discuss history, discovery, knowledge, and the next step through a new and more detailed …

Limits on the Diffuse Gamma-Ray Background above 10 TeV with HAWC

HAWC Collaboration, A. Albert, R. Alfaro, Cesar Omar Ramirez Alvarez et autres

The high-energy Diffuse Gamma-Ray Background (DGRB) is expected to be produced by unresolved isotropically distributed astrophysical objects, potentially including dark matter annihilation or decay emissions in galactic or extragalactic structures. The DGRB has only been observed below 1 TeV; above this energy, …

Spectrum and Morphology of the Very-High-Energy Source HAWC J2019+368

HAWC Collaboration, A. Albert, R. Alfaro, C. Alvarez et autres

The MGRO J2019+37 region is one of the brightest sources in the sky at TeV energies. It was detected in the 2 year HAWC catalog as 2HWC J2019+367 and here we present a detailed study of this region using data from HAWC. …

List of proceedings from the HAWC Collaboration presented at the 36th International Cosmic Ray Conference, 24 July - 1 August 2019, Madison, Wisconsin, USA.

UNDERSTANDING THE VERY HIGH ENERGY γ-RAY EMISSION FROM A FAST SPINNING NEUTRON STAR ENVIRONMENT

C. Brisbois

Pulsars, and their associated pulsar wind nebulae, are factories producing high energy electrons and positrons in our galaxy. The Dragonfly nebula is a Vela-like pulsar wind nebula in the Cygnus region powered by the spin down of PSR J2021+3651. The TeV γ-ray …
