Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; Hoang, Kim Dinh ; López Moya, Marcos ; Miener, Tjark ; Miranda Pantoja, José Miguel ; Morcuende, D. ; Peñil del Campo, Pablo ; Saha, Lab ; otros, ... | Wiley | 2020-08Extreme high-frequency BL Lacs (EHBL) feature their synchrotron peak of the broad-band spectral energy distribution (SED) at nu(s) > = 10(17) Hz. The BL Lac object 1ES 2344+514 was included in the EHBL family because of its impressive shift of t[...]texto impreso

In the presence of a sufficient amount of target material, gamma-rays can be used as a tracer in the search for sources of Galactic cosmic rays (CRs). Here we present deep observations of the Galactic center (GC) region with the MAGIC tele[...]texto impreso

A. ; otros, ... | Elsevier Science BV | 2019-09The Cherenkov Telescope Array (CTA) is the major next-generation observatory for ground-based veryhigh-energy gamma-ray astronomy. It will improve the sensitivity of current ground-based instruments by a factor of five to twenty, depending on th[...]texto impreso

They also feature nonthermal gamma-ray emission whose peak lies in the very high-energy (VHE, E > 100 GeV) range, and in som[...]texto impreso
Morcuende, D. ; Rosado, J. ; Contreras González, José Luis ; Arqueros Martínez, Fernando | Elsevier Science BV | 2019-01Atmospheric fluorescence is usually neglected in the reconstruction of the signals registered by Cherenkov telescopes, both IACTs and wide-angle detector arrays. In this paper we quantify the fluorescence contribution to the total light recorded[...]texto impreso

It has become evident that one-zone synchrotron self-Compton models are not always adequate for very high-energy (VHE) gamma-ray-emitting blazars. While two-component models perform better, they are difficult to constrain due to the lar[...]texto impreso
