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…
First Study of Combined Blazar Light Curves with FACT and HAWC
Daniela Dorner, Robert J. Lauer, : +28
For studying variable sources like blazars, it is crucial to achieve unbiased monitoring, either with dedicated telescopes in pointing mode or survey instruments. At TeV energies,…
Super-orbital variability of LS I +61°303 at TeV energies
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +150
The gamma-ray binary LS I +61303 is a well established source from centimeter radio up to very high energy (VHE; E100 GeV). Its broadband emission shows a periodicity…
Multi-Wavelength Observations of the Blazar 1ES 1011+496 in Spring 2008
The MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +158
The BL Lac object 1ES 1011+496 was discovered at Very High Energy gamma-rays by MAGIC in spring 2007. Before that the source was little studied in different wavelengths. Therefore…
Insights into the emission of the blazar 1ES 1011+496 through unprecedented broadband observations during 2011 and 2012
J. Aleksić, S. Ansoldi, L. A. Antonelli +161
1ES 1011+496 was discovered in very high energy (VHE, E >100 GeV) -rays with MAGIC in 2007. The absence of simultaneous data at lower energies led to a rather incomp…
Investigating the peculiar emission from the new VHE gamma-ray source H1722+119
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +159
The MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov) telescopes observed the BL Lac object H1722+119 (redshift unknown) for six consecutive nights between 2013 May 17 and 22,…
MAGIC observations of the February 2014 flare of 1ES 1011+496 and ensuing constraint of the EBL density
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +144
In February-March 2014, the MAGIC telescopes observed the high-frequency peaked BL Lac 1ES 1011+496 (z=0.212) in flaring state at very-high energy (VHE, E>100GeV). The flux reached…
Limits to dark matter annihilation cross-section from a combined analysis of MAGIC and Fermi-LAT observations of dwarf satellite galaxies
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +154
We present the first joint analysis of gamma-ray data from the MAGIC Cherenkov telescopes and the Fermi Large Area Telescope (LAT) to search for gamma-ray signals from dark matter…
Deep observation of the NGC 1275 region with MAGIC: search of diffuse gamma-ray emission from cosmic rays in the Perseus cluster
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +154
Clusters of galaxies are expected to be reservoirs of cosmic rays (CRs) that should produce diffuse gamma-ray emission due to their hadronic interactions with the intra-cluster med…
