Multiband variability studies and novel broadband SED modeling of Mrk 501 in 2009
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +290
We present an extensive study of the BL Lac object Mrk 501 based on a data set collected during the multi-instrument campaign spanning from 2009 March 15 to 2009 August 1 which inc…
Observations of Sagittarius A* during the pericenter passage of the G2 object with MAGIC
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +153
Context. We present the results of a multi-year monitoring campaign of the Galactic Center (GC) with the MAGIC telescopes. These observations were primarily motivated by reports th…
A search for spectral hysteresis and energy-dependent time lags from X-ray and TeV gamma-ray observations of Mrk 421
A. U. Abeysekara, S. Archambault, A. Archer +220
Blazars are variable emitters across all wavelengths over a wide range of timescales, from months down to minutes. It is therefore essential to observe blazars simultaneously at di…
Very High-Energy Gamma-Ray Follow-Up Program Using Neutrino Triggers from IceCube
IceCube Collaboration, M. G. Aartsen, K. Abraham +537
We describe and report the status of a neutrino-triggered program in IceCube that generates real-time alerts for gamma-ray follow-up observations by atmospheric-Cherenkov telescope…
Cosmic ray composition measurements and cosmic ray background free gamma-ray observations with Cherenkov telescopes
A. Neronov, D. V. Semikoz, Ie. Vovk +1
Muon component of extensive air showers (EAS) initiated by cosmic ray particles carries information on the primary particle identity. We show that the muon content of EAS could be…
Detection of very high energy gamma-ray emission from the gravitationally-lensed blazar QSO B0218+357 with the MAGIC telescopes
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +151
Context. QSO B0218+357 is a gravitationally lensed blazar located at a redshift of 0.944. The gravitational lensing splits the emitted radiation into two components, spatially indi…
