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,…
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…
The major upgrade of the MAGIC telescopes, Part I: The hardware improvements and the commissioning of the system
MAGIC Collaboration, J. Aleksic, S. Ansoldi +162
The MAGIC telescopes are two Imaging Atmospheric Cherenkov Telescopes (IACTs) located on the Canary island of La Palma. The telescopes are designed to measure Cherenkov light from…
The major upgrade of the MAGIC telescopes, Part II: A performance study using observations of the Crab Nebula
MAGIC Collaboration, J. Aleksic, S. Ansoldi +163
MAGIC is a system of two Imaging Atmospheric Cherenkov Telescopes located in the Canary island of La Palma, Spain. During summer 2011 and 2012 it underwent a series of upgrades, in…
Probing the very-high-energy gamma-ray spectral curvature in the blazar PG 1553+113 with the MAGIC telescopes
MAGIC Collaboration, J. Aleksić, S. Ansoldi +152
PG 1553+113 is a very-high-energy (VHE, ) -ray emitter classified as a BL Lac object. Its redshift is constrained by intergalactic absorption lines in the r…
FACT -- Operation of the First G-APD Cherenkov Telescope
T. Bretz, A. Biland, J. Buß +33
Since more than two years, the First G-APD Cherenkov Telescope (FACT) is operating successfully at the Canary Island of La Palma. Apart from its purpose to serve as a monitoring fa…
Signal discovery, limits, and uncertainties with sparse On/Off measurements: an objective Bayesian analysis
Max L. Knoetig
For decades researchers have studied the On/Off counting problem, where a measured rate consists of two parts. One due to a signal process and another due to a background process,…
FACT -- The G-APD revolution in Cherenkov astronomy
T. Bretz, H. Anderhub, M. Backes +53
Since two years, the FACT telescope is operating on the Canary Island of La Palma. Apart from its purpose to serve as a monitoring facility for the brightest TeV blazars, it was bu…
Multifrequency Studies of the Peculiar Quasar 4C +21.35 During the 2010 Flaring Activity
M. Ackermann, M. Ajello, A. Allafort +288
The discovery of rapidly variable Very High Energy (VHE; E > 100 GeV) gamma-ray emission from 4C +21.35 (PKS 1222+216) by MAGIC on 2010 June 17, triggered by the high activity dete…
Calibration and performance of the photon sensor response of FACT -- The First G-APD Cherenkov telescope
A. Biland, T. Bretz, J. Buß +33
The First G-APD Cherenkov Telescope (FACT) is the first in-operation test of the performance of silicon photo detectors in Cherenkov Astronomy. For more than two years it is operat…
