 2017-09-2008:55 [PUBDB-2017-10908] Report/Journal Article et al The second catalog of flaring gamma-ray sources from the Fermi All-sky Variability Analysis [arXiv:1612.03165] The astrophysical journal 846(1), 34 - (2017) [10.3847/1538-4357/aa8092]   We present the second catalog of flaring gamma-ray sources (2FAV) detected with the Fermi All-sky Variability Analysis (FAVA), a tool that blindly searches for transients over the entire sky observed by the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope. With respect to the first FAVA catalog, this catalog benefits from a larger data set, the latest LAT data release (Pass 8), as well as from an improved analysis that includes likelihood techniques for a more precise localization of the transients.

The current CTA design consists of two arrays of tens of imaging atmospheric Cherenkov Telescopes, comprising Small, Medium and Large-Sized Telescopes, with one array located in each of the Northern and Southern Hemispheres [...] Restricted: PDF PDF (PDFA); 2017-07-1710:51 [PUBDB-2017-07734] Journal Article et al Modelling Jets, Tori and Flares in Pulsar Wind Nebulae Space science reviews 207(1-4), 137 - 174 (2017) [10.1007/s11214-017-0344-x]   In this contribution we review the recent progress in the modelling of Pulsar Wind Nebulae (PWN). We start with a brief overview of the relevant physical processes in the magnetosphere, the wind-zone and the inflated nebula bubble [...] Restricted: PDF PDF (PDFA); 2017-06-1415:45 [PUBDB-2017-04984] Report/Journal Article et al Prospects for Cherenkov Telescope Array Observations of the Young Supernova Remnant RX J1713.7-3946 [arXiv:1704.04136] The astrophysical journal 840(2), 74 (2017) [10.3847/1538-4357/aa6d67]   We perform simulations for future Cherenkov Telescope Array (CTA) observations of RX J1713.7−3946, a young supernova remnant (SNR) and one of the brightest sources ever discovered in very high energy (VHE) gamma rays. Special attention is paid to exploring possible spatial (anti)correlations of gamma rays with emission at other wavelengths, in particular X-rays and CO/H i emission.

Improved $\gamma$/hadron separation for the detection of faint $\gamma$-ray sources using boosted decision trees   Imaging atmospheric Cherenkov telescopes record an enormous number of cosmic-ray background events. Suppressing these background events while retaining $\gamma$-rays is key to achieving good sensitivity to faint $\gamma$-ray sources.

(2016) [10.3204/PUBDB-2017-00337] = Humboldt-Universität zu Berlin, Diss., 2016   In astronomy, many of the observed sources show a transient behavior. Examples aregamma-ray bursts (GRBs) and active galactic nuclei (AGN).

They are thought to be sites of cosmic-ray acceleration, and are predicted to emit $\gamma$-rays in the GeV to TeV range.

Most current results are obtained either from di-rect measurements by balloon- or satellite-borne detectors, or from indirect measurements byair shower detector arrays on the Earth’s surface.
