Black hole lightning due to particle acceleration at subhorizon scales
MAGIC Collaboration, J. Aleksić, S. Ansoldi +151
Supermassive black holes with masses of millions to billions of solar masses are commonly found in the centers of galaxies. Astronomers seek to image jet formation using radio inte…
An extreme gravitationally redshifted iron line at 4.8 keV in Mrk 876
Eugenio Bottacini, Elena Orlando, Jochen Greiner +3
X-ray spectral lines at unforeseen energies are important because they can shed light on the extreme physical conditions of the environment around the supermassive black holes of a…
Unprecedented study of the broadband emission of Mrk 421 during flaring activity in March 2010
The MAGIC Collaboration, J. Aleksić, S. Ansoldi +251
A flare from the TeV blazar Mrk 421, occurring in March 2010, was observed for 13 consecutive days from radio to very high energy (VHE, E > 100 GeV) gamma-rays with MAGIC, VERITAS,…
Discovery of very high energy gamma-ray emission from the blazar 1ES 0033+595 by the MAGIC telescopes
J. Aleksić, S. Ansoldi, L. A. Antonelli +157
The number of known very high energy (VHE) blazars is , which is very small in comparison to the number of blazars detected in other frequencies. This situation is a hand…
Multiwavelength observations of Mrk 501 in 2008
MAGIC Collaboration, J. Aleksić, S. Ansoldi +256
Mrk 501 is one of the brightest blazars at TeV energies and has been extensively studied since its first VHE detection in 1996. Our goal is to characterize in detail the source gam…
First broadband characterization and redshift determination of the VHE blazar MAGIC J2001+439
MAGIC Collaboration, J. Aleksić, S. Ansoldi +167
We aim to characterize the broadband emission from 2FGL J2001.1+4352, which has been associated with the unknown-redshift blazar MG4 J200112+4352. Based on its gamma-ray spectral p…
