dc.description.abstract | The flat spectrum radio quasar (FSRQ) PKS 1510-089 (z=0.361) is known for its complex multiwavelength
behavior. It has been monitored regularly at very high energy (VHE, E > 100GeV)
gamma-rays with H.E.S.S. since its discovery in 2009 in order to study the unknown behavior
of FSRQs in quiescence at VHE, as well as the flux evolution around flaring events. Given the
expected strong cooling of electrons and the absorption of VHE emission within the broad-line
region, a detection of PKS 1510-089 at VHE in a quiescent state would be an important result, implying
an acceleration and emission region on scales beyond the broad-line region. The H.E.S.S.
monitoring has been intensified since 2015 and is complemented by monitoring at high energy
(E > 100MeV) gamma-rays with Fermi, at X-rays with Swift-XRT, and at optical frequencies
with ATOM. The dense lightcurves allow for the first time detailed comparison studies between
these energy bands. The source has been active in several frequency bands for a large fraction of
the observation time frames. Yet, we do not find obvious correlations between the VHE and the
other bands over the observed time frame indicating a non-trivial interplay of the acceleration,
cooling and radiative processes. It also implies a rich variety in flaring behavior, which makes
this source difficult to interpret within a unique theoretical framework | en_US |
