Abstract:
Observations of the gamma-ray sky with Fermi led to significant
advances towards understanding blazars, the most extreme class of
active galactic nuclei. A large fraction of the population detected
by Fermi is formed by BL Lacertae (BL Lac) objects, whose sample has
always suffered from a severe redshift incompleteness due to the
quasi-featureless optical spectra.
Our goal is to provide a significant increase of the number of
confirmed high-redshift BL Lac objects contained in the 2 LAC
Fermi/LAT catalog.
Description:
For 103 Fermi/LAT blazars, photometric redshifts using spectral energy
distribution fitting have been obtained. The photometry includes 13
broad-band filters from the far ultraviolet to the near-IR observed
with Swift/UVOT and the multi-channel imager GROND at the MPG/ESO 2.2m
telescope. Data have been taken quasi-simultaneously and the remaining
source-intrinsic variability has been corrected for.
