The connection between jets and host galaxies of radio loud AGN: Blazars vs NLSy1s
, 2018 This doctoral dissertation discuss the main properties of the host galaxies of those active galactic nuclei (AGN) capable of generating strong relativistic jets (and therefore, capable of emitting up to the γ−ray energy ranges) and with their jets ...

A Universal Physics Defining the Radiation Spectra of Blazars and Gamma-Ray Bursts
The Astrophysical JournalBlazars and gamma-ray bursts (GRBs) are both cosmic beacons of extreme energy release powered by relativistic jets. However, they originate from tremendously different environments. Blazars are the sustained powerhouses driven by supermassive black holes

, 2014 We fit (quasi-)simultaneous multi-waveband spectral energy distributions for a sample of low-synchrotron-peaked (LSP) blazars with a one-zone leptonic model.

Publications of the Astronomical Society of Japan, 2002 Based on the beaming model, a relation between the observed polarization and the Doppler factor was obtained by Fan et al. (1997, AAA068.159.190), who showed that the polarization is associated with the Doppler factor (boosting factor) in BL Lacertae objects (BLs).

The relation between black hole masses and Lorentz factors of the jet components in blazars
, 2009 We explore the relationship between black hole mass (M(BH)) and the motion of the jet components for a sample of blazars. The Very Long Baseline Array (VLBA) 2 cm Survey and its continuation: Monitoring of Jets in active galactic nuclei (AGNs) with VLBA ...

The space density of z>4 blazars [PDF]
, 2019 High-redshift blazars are an important class of active galactic nuclei (AGN) that can provide an independent estimate of the supermassive black hole mass function in high-redshift radio-loud AGN without the bias due to absorption along the line of sight.
