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…
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…
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…
