Abstract:
Simultaneous broadband spectral and temporal studies of blazars are an
important tool for investigating active galactic nuclei (AGN) jet
physics.
We study the spectral evolution between quiescent and flaring periods
of 22 radio-loud AGN through multiepoch, quasi-simultaneous broadband
spectra. For many of these sources these are the first broadband
studies.
We use a Bayesian block analysis of Fermi/LAT light curves to
determine time ranges of constant flux for constructing
quasi-simultaneous spectral energy distributions (SEDs). The shapes of
the resulting 81 SEDs are described by two logarithmic parabolas and a
blackbody spectrum where needed.
Description:
The Dynamic SEDs of southern blazars catalog is based on a TANAMI
multiwavelength project that has been monitoring a sample of 22
radio-loud blazars of the southern sky from radio to gamma-ray
wavelengths.

If confidence level values are given as 0.0, the parameter was frozen in
the fit.
If the value itself is given as 0.0 the fit component was not used for
this fit.
