An observational determination of the evolving extragalactic background light from the multiwavelength HST/CANDELS survey in the Fermi and CTA era

Alberto Saldana-Lopez, Alberto Domínguez, Pablo G. Pérez-González +5

The diffuse extragalactic background light (EBL) is formed by ultraviolet (UV), optical, and infrared (IR) photons mainly produced by star formation processes over the history of t…

Unravelling the complex behavior of Mrk 421 with simultaneous X-ray and VHE observations during an extreme flaring activity in April 2013

MAGIC collaboration, V. A. Acciari, S. Ansoldi +237

We report on a multi-band variability and correlation study of the TeV blazar Mrk 421 during an exceptional flaring activity observed from 2013 April 11 to 2013 April 19. The study…

Gamma-ray observations of low-luminosity active galactic nuclei

Raniere de Menezes, Rodrigo Nemmen, Justin D. Finke +2

The majority of the activity around nearby (z ~ 0) supermassive black holes is found in low-luminosity active galactic nuclei (LLAGN), the most of them being classified as low ioni…
