Redshift constrain of BL Lac PKS 1424+240
Sarira Sahu, D. I. Páez-Sánchez, B. Medina-Carrillo +3
In the period between 2009 and 2015, several very high-energy (VHE GeV) gamma-ray flaring events from the BL Lac object PKS 1424+240 were observed by the Cerenkov telescope…
TeV afterglow from GRB 221009A: photohadronic origin?
Sarira Sahu, B. Medina-Carrillo, D. I. Páez-Sánchez +2
Gamma-ray burst (GRB), GRB 221009A, a long-duration GRB, was observed simultaneously by the Water Cherenkov Detector Array (WCDA) and the Kilometer Squared Array (KM2A) of the Larg…
A photohadronic interpretation of the H.E.S.S. afterglow observations from GRB 221009A
Sarira Sahu, B. Medina-Carrillo, D. I. Páez-Sánchez +2
The High Energy Stereoscopic System (H.E.S.S.) started observing the extremely powerful long-duration gamma-ray burst, GRB 221009A, after 53 hours of the triggering event. The H.E.…
Constraining the redshift of BL Lac VER J0521+211
Sarira Sahu, B. Medina-Carrillo, G. Sánchez-Colón +1
Observation of several very high energy (VHE) flaring events of the BL Lac object VER J0521+211 were reported by the VERITAS and MAGIC collaborations between 2009 and 2014. The red…
Deciphering the ~18 TeV photons from GRB 221009A
Sarira Sahu, B. Medina-Carrillo, G. Sánchez-Colón +1
On 9 October, 2022, an extremely powerful gamma-ray burst, GRB 221009A, was detected by several instruments. Despite being obstructed by the Milky Way galaxy, its afterglow outburs…
Very high energy emission mechanism in the extreme blazar PGC 2402248
B. Medina-Carrillo, Sarira Sahu, G. Sánchez-Colón +1
Extreme high-frequency peaked BL Lacs (EHBLs) are characterized by a synchrotron peak frequency exceeding Hz and a second peak that can be in the energy range of few GeVs…
