Failed jet breakout in the metal-poor broad-lined type Ic supernova 2026gzf
Antonio Martin-Carrillo, Christina C. Thöne, James K. Leung +103
A long-standing question in the death of massive stars is the role of relativistic jets. While many gamma-ray bursts and some fast X-ray transients seem to be associated with broad…
GRB 260310A / SN 2026fgk: A Multi-Wavelength Study of a Nearby Underluminous Long GRB and SN with a Complex Afterglow
Ramandeep Gill, Rosa L. Becerra, Antonio de Ugarte Postigo +65
We present a comprehensive multi-wavelength study of GRB 260310A / SN 2026fgk, a nearby (), long-duration gamma-ray burst (GRB) with an exceptionally underluminous prompt…
Hadronic Clues in Quasars Caught by Fermi-LAT
Antonio Galván, Nissim Fraija, Edilberto Aguilar-Ruiz +3
This work explores whether hadronic processes could be responsible for the high-energy emission seen in quasars identified by the Large Area Telescope (LAT) instrument aboard the F…
Synchrotron Self-Compton Model of TeV Afterglows in Gamma-Ray Bursts
Edilberto Aguilar-Ruiz, Ramandeep Gill, Paz Beniamini +1
The detection of a very-high-energy TeV spectral component in the afterglow emission of gamma-ray bursts (GRBs) has opened a new probe into the energetics of ultra-relativistic bla…
