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…
Fermion scattering in a Bose-Einstein condensate
César E. EchevarrÃa, José F. Nieves, Francisco Orbe +1
In a recent work, we considered the propagation of fermions in the background of a scalar Bose-Einstein (BE) condensate. Using some illustrative Yukawa-type coupling models between…
Plasmon damping in a charged Bose-Einstein condensate model
José F. Nieves, Sarira Sahu
In this work we consider the calculation of the imaginary part of the dispersion relations of the propagating modes in a model of a charged scalar Bose-Einstein (BE) condensate, as…
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…
