An Explanation of GRB Fermi-LAT Flares and High-Energy Photons in Stratified Afterglows

Nissim Fraija, Boris Betancourt Kamenetskaia, Antonio Galván-Gámez +6

The second {\itshape Fermi}/LAT gamma-ray burst (GRB) catalog (2FLGC) spanning the first decade of operations by the LAT collaboration was recently released. The closure relations…

Off-axis Afterglow Closure Relations and Fermi-LAT Detected Gamma-Ray Bursts

Nissim Fraija, M. G. Dainotti, D. Levine +2

Gamma-ray bursts (GRBs) are one of the most promising transient events for studying multi-wavelength observations in extreme conditions. Observation of GeV photons from bursts woul…

Closure Relations of Synchrotron Self-Compton in Afterglow stratified medium and Fermi-LAT Detected Gamma-Ray Bursts

Nissim Fraija, Maria G. Dainotti, B. Betancourt Kamenetskaia +2

The Second Gamma-ray Burst Catalog (2FLGC) was announced by the Fermi Large Area Telescope (Fermi-LAT) Collaboration. It includes 29 bursts with photon energy higher than 10 GeV. G…

Evidence of a lepto-hadronic two-zone emission in flare states

E. Aguilar-Ruiz, N. Fraija, A. Galván-G ámez

The BL Lac Markarian 501 exhibited two flaring activities in the very-high-energy (VHE) band in May 2009. The lack of correlation between X-rays and TeV gamma-rays without increasi…

High-Energy Neutrino Fluxes from Hard-TeV BL Lacs

E. Aguilar-Ruiz, N. Fraija, A. Galván-Gámez

Blazars have been pointed out as promising high-energy (HE) neutrinos sources, although the mechanism is still under debate. The blazars with a hard-TeV spectrum, which leptonic mo…
