Deciphering the VHE gamma-rays spectra of Extreme High-Frequency peaked BL Lac Objects through a Photohadronic Model
Sarira Sahu, D. I. Páez-Sánchez, A. U. Puga Oliveros +7
Extreme high-frequency peaked BL Lac objects (EHBLs) have their synchrotron peak above keV and their inverse Compton peak extends up to several TeVs. Due to low luminosity…
Rapid Variability and Broadband Spectral Modeling in the Flaring Activity of BL Lacertae
Xin Chang, Dingrong Xiong, Chenxu Liu +17
We report a multi-wavelength study of two flaring episodes of the blazar BL Lacertae during MJD 60500-60800 (9 July 2024 - 5 May 2025). The source reached a daily-averaged -ray…
Constraining the redshift of PG 1553+113 using the photohadronic model
Sarira Sahu, R. de J. Pacheco-Aké, G. Sánchez-Colón +3
Between 2005 and 2015, the BL Lacertae object PG 1553+113 exhibited multiple very high-energy (VHE; > 100 GeV) gamma-ray flares, which were detected by the Cherenkov telescopes, Hi…
Temporary EHBL-like behavior of Markarian 501 during July 2014 VHE flaring
Sarira Sahu, A. U. Puga Oliveros, D. I. Páez-Sánchez +6
Markarian 501, a BL Lac object well-known as a high energy gamma-ray source, has exhibited several epochs of very high energy (VHE) gamma-ray flaring events when its synchrotron pe…
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…
