CONSTRAINTS ON THE MINIMUM ELECTRON LORENTZ FACTOR AND MATTER CONTENT OF JETS FOR A SAMPLE OF BRIGHT FERMI BLAZARS

Abstract: We fit the (quasi-)simultaneous multi-waveband spectral energy distributions (SEDs) for a sample of low-synchrotron-peaked (LSP) blazars with a one-zone leptonic model. The seed photons that predominantly come from broad line region (BLR) and infrared (IR) molecular torus are considered respectively in external Compton process. We find that the modeling with IR seed photons is systematically better than that with BLR photons based on a χ 2 test, which suggest that γ-ray emitting region most possibly stay outsi… Show more

“…Of course, that means that in those cases the precise value is ill-constrained, as at these high values changes in the cutoff value lead to very small changes in the light curves, but that does not invalidate the general conclusion that these flows do not have particle energy spectra extending far below the energy responsible for the centimeter-band emission. The values found in this analysis are in agreement with the range of values found by Kang et al (2014) (from 5 to 160, with a median of 55).…”

“…For the model description, see the Appendix for detail (see also Chen et al 2012;Kang et al 2014). During our modeling, the Doppler beaming factor is assumed to be same as that in Baloković et al (2016), i.e., δ = 25.…”

“…These lowest-energy electrons will IC scatter the soft seed photons and emit at the X-ray band. Therefore, careful SED modeling (especially modeling the IC X-ray spectra) is widely used to estimate the minimal electron energy and furthermore to calculate, for example, the jet power (see, e.g., Celotti & Ghisellini 2008;Chen et al 2010;Kang et al 2014;Ghisellini et al 2014). …”

“…In order to minimize hardening introduced from EBL absorption corrections, we adopt the absorption optical depth that derived from the EBL model proposed by Domínguez et al (2011) in our calculations. In our SED modeling of Figure 1, we assume the model prediction as the intrinsic emission and correct it to our local universe using equation (2), and compare it with the observational data (e.g., Zheng & Zhang 2011;Zheng et al , 2014Kang et al 2014). …”
