Description |
I will talk about the Spectral Energy Distribution (SED) modeling
of the blazar BL Lacertae for the period starting from 9th May
to 8th July, 2011, when it was in a relatively high state in gamma
rays. I will present the broadband energy spectrum using data from
the Fermi-LAT, the RXTE-PCA, the Swift-XRT and the Swift-
UVOT, with special emphasis on the LAT data. The broadband
SED is then modeled using a one zone leptonic model considering
synchrotron and synchrotron self Compton processes. Our present
model fails to reproduce the observed spectrum. I will also speak a
few words about the data analysis of the HAGAR telescope system
at Hanle,Ladakh.
