Secular effects of ultralight dark matter on binary pulsars

Dark matter (DM) can consist of very light bosons behaving as a classical scalar field that experiences coherent oscillations. The presence of this DM field would perturb the dynamics of celestial bodies, either because the (oscillating) DM stress tensor m ...

Teraelectronvolt pulsed emission from the Crab Pulsar detected by MAGIC

Thomas Günther Bretz

Aims. We investigate the extension of the very high-energy spectral tail of the Crab Pulsar at energies above 400 GeV. Methods. We analyzed similar to 320 h of good-quality Crab data obtained with the MAGIC telescope from February 2007 to April 2014. Resul ...

Deep observation of the NGC1275 region with MAGIC: search of diffuse gamma-ray emission from cosmic rays in the Perseus cluster

Thomas Günther Bretz

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 medium. The nearby Perseus cool-core cluster, identified as the most promising ...

Multiwavelength observations of Mrk 501 in 2008

Xin Chen, Thomas Günther Bretz

Context. Blazars are variable sources on various timescales over a broad energy range spanning from radio to very high energy (>100 GeV, hereafter VHE). Mrk 501 is one of the brightest blazars at TeV energies and has been extensively studied since its firs ...

CFHTLenS: weak lensing calibrated scaling relations for low-mass clusters of galaxies

Jean-Paul Richard Kneib

L(X)We present weak lensing and X-ray analysis of 12 low-mass clusters from the Canada-France-Hawaii Telescope Lensing Survey and XMM-CFHTLS surveys. We combine these systems with high-mass systems from Canadian Cluster Comparison Project and low-mass syst ...

MAGIC reveals a complex morphology within the unidentified gamma-ray source HESS J1857+026

Thomas Günther Bretz

Aims. HESS J1857+026 is an extended TeV gamma-ray source that was discovered by H. E. S. S. as part of its Galactic plane survey. Given its broadband spectral energy distribution and its spatial coincidence with the young energetic pulsar PSR J1856+0245, t ...

Neutrino Analysis Of The 2010 September Crab Nebula Flare And Time-Integrated Constraints On Neutrino Emission From The Crab Using Icecube

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

We present the results of a search for high-energy muon neutrinos with the IceCube detector in coincidence with the Crab Nebula flare reported on 2010 September by various experiments. Due to the unusual flaring state of the otherwise steady source we perf ...

FACT-The first Cherenkov telescope using a G-APD camera for TeV gamma-ray astronomy

Werner Lustermann, Mathieu Ribordy, Thomas Günther Bretz

Geiger-mode Avalanche Photodiodes (G-APD) bear the potential to significantly improve the sensitivity of Imaging Air Cherenkov Telescopes (IACT). We are currently building the First G-APD Cherenkov Telescope (FACT) by refurbishing an old IACT with a mirror ...
