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…
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…
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…
FACT - Threshold prediction for higher duty cycle and improved scheduling
T. Bretz, A. Biland, J. Buß +22
The First G-APD Cherenkov telescope (FACT) is the first telescope using silicon photon detectors (G-APD aka. SiPM). The use of Silicon devices promise a higher photon detection eff…
