Search for Gamma-ray Spectral Lines from Dark Matter Annihilation in Dwarf Galaxies with the High-Altitude Water Cherenkov Observatory
The HAWC Collaboration
Local dwarf spheroidal galaxies (dSphs) are nearby dark-matter dominated systems, making them excellent targets for searching for gamma rays from particle dark matter interactions.…
Constraints on Lorentz invariance violation from HAWC observations of gamma rays above 100 TeV
HAWC Collaboration, A. Albert, R. Alfaro +90
Due to the high energies and long distances to the sources, astrophysical observations provide a unique opportunity to test possible signatures of Lorentz invariance violation (LIV…
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…
Search for very-high-energy emission with HAWC from GW170817 event
Antonio Galvan-Gamez, Nissim Fraija, M. Magdalena Gonzalez
The detection of the gravitational wave GW170817 defined a breakthrough in multi-messenger astronomy. For the first time, a gravitational wave transient detected by the Laser Inter…
Optical polarimetric and multiwavelength flaring activity of blazar 3C279
N. Fraija, E. Benítez, D. Hiriart +5
An exhaustive analysis of 9-year optical R-band photopolarimetric data of the flat-spectrum radio quasar 3C279 from 2008 February 27 to 2017 May 25 is presented, alongside with mul…
Study of PeV neutrinos around dwarf galaxies near giant lobes of Centaurus A
E. Aguilar-Ruiz, N. Fraija, A. Galván-Gámez +2
The origin of recently discovered PeV neutrinos is an unsolved problem. In this work we consider a hadronic scenario to produce PeV neutrinos from a region around giant lobes of Ce…
Description of atypical bursts seen slightly off-axis
N. Fraija, F. De Colle, P. Veres +5
The detection of gravitational waves together with their electromagnetic counterpart, in the gamma-ray burst GRB 170817A, marked a new era of multi-messenger astronomy. Several the…
Modeling the observations of GRB 180720B: From radio to sub-TeV gamma-rays
N. Fraija, S. Dichiara, A. C. Caligula do E. S. Pedreira +6
Early and late multiwavelength observations play an important role in determining the nature of the progenitor, circumburst medium, physical processes and emitting regions associat…
Analysis and modelling of the multi-wavelength observations of the luminous GRB 190114C
N. Fraija, S. Dichiara, A. C. Caligula do E. S. Pedreira +4
Very-high-energy (VHE; GeV) photons are expected from the nearest and brightest Gamma-ray bursts (GRBs). VHE photons, at energies higher than 300 GeV, were recently repor…
