Time dependent hadronic modeling of flat spectrum radio quasars
(American Astronomical Society, 2015)
We introduce a new time-dependent lepto-hadronic model for blazar emission that takes into account the radiation
emitted by secondary particles, such as pions and muons, from photo hadronic interactions. Starting from ...
H.E.S.S. reveals a lack of TeV emission from the supernova remnant Puppis A
(EDP Sciences, 2015)
Context: Puppis A is an interesting ~4 kyr-old supernova remnant (SNR) that shows strong evidence of interaction between the forward shock and a molecular cloud. It has been studied in detail from radio frequencies to ...
Discovery of variable VHE γ-ray emission from the binary system 1FGL J1018.6-5856
(EDP Sciences, 2015)
Re-observations with the HESS telescope array of the very high-energy (VHE) source HESS J1018–589 A that is coincident with the Fermi-LAT γ-ray binary 1FGL J1018.6–5856 have resulted in a source detection significance of ...
Probing cluster environments of blazars through γγ absorption
(EDP Sciences, 2015)
Most blazars are known to be hosted in giant elliptic galaxies, but their cluster environments have not been thoroughly investigated. Cluster environments may contain radiation fields of low-energy photons created by nearby ...
Hadronic models of blazars require a change of the accretion paradigm
(Oxford University Press, 2015)
We study hadronic models of broad-band emission of jets in radio-loud active galactic nuclei, and their implications for the accretion in those sources. We show that the models that account for broad-band spectra of blazars ...
