Modeling and validation of losses due to unbalanced loading of stand-alone generators
(IEEE, 2017)
The goal of this paper is to evaluate the possibility of deriving a simple lumped electrical model of the additional losses in stand-alone synchronous generators due to unbalanced loading. An in depth analysis will reveal ...
Analysis of PM transverse-flux outer rotor machines with different configuration
(IEEE, 2017)
This paper presents the electromagnetic analysis of two permanent magnet transverse-flux outer rotor machines with and without magnetic shunts. The research started with designing and analyzing a permanent magnet transverse-flux ...
Probing Vela pulsar down to 20 GeV with H.E.S.S. II observations
(AIP, 2017)
Observations of the Vela pulsar (PSR B0833-45) with the High Energy Stereoscopic System phase II array (H.E.S.S. II) have resulted in a high-significance detection of its pulsed emission down to 20 GeV. The very low-energy ...
Implications of time-dependent injection in relativistic jets
(AIP, 2017)
Rapid blazar flaring events and their rich behavior require time-dependent modeling. One important approach is time-dependent injection causing non-linear cooling effects, since the inevitable SSC cooling depends on the ...
The extended jet in AP Librae as the source of the VHE γ-ray emission
(AIP, 2017)
Most modeling attempts of blazars use a small emission zone located close to the central black hole in order to explain the broad-band spectral energy distribution. Here we present a case where additionally to the small ...
The H.E.S.S. II GRB observation scheme
(AIP, 2017)
Gamma-ray bursts (GRBs) are some of the Universe’s most enigmatic and exotic events. However, at energies above 10 GeV their behaviour remains largely unknown. Although space based telescopes such as the Fermi-LAT have ...
The complex VHE and multiwavelength flaring activity of the FSRQ PKS 1510-089 in May 2015
(AIP, 2017)
The blazar PKS 1510-089 was the first of the flat spectrum radio quasar type, which had been detected simultaneously by a ground based Cherenkov telescope (H.E.S.S.) and the LAT instrument on board the Fermi satellite. ...
Target of opportunity observations of blazars with H.E.S.S.
(AIP, 2017)
The very high energy (VHE, E > 100 GeV) sky is dominated by blazars, radio-loud active galactic nuclei whose relativistic jet is closely aligned with the line of sight. Blazars are characterized by rapid variability at all ...
Diagnosing relativistic particle acceleration in AGN jets
(AIP, 2017)
Mildly relativistic, oblique shocks are generally considered to be among the most plausible sites of relativistic particle acceleration and the subsequent production of strongly variable, polarized multi-wavelength emission ...
