VLBI observations of seven BL Lac objects from RGB sample

Zhongzu Wu, D. R. Jiang, Minfeng Gu +1

We present EVN observations of seven BL Lac objects selected from the RGB sample. To investigate the intrinsic radiation property of BL Lac objects, we estimated the Doppler factor…

EVN observations of eleven GHz-Peaked-Spectrum radio sources at 2.3/8.4GHz

L. Xiang, D. Dallacasa, P. Cassaro +2

We present results of EVN observations of eleven GHz-Peaked-Spectrum (GPS) radio sources at 2.3/8.4 GHz. These sources are from the classical ''bright'' GPS source samples with pea…

The Center of Activity in the CSS Superluminal Source 3C 138

Z. -Q. Shen, L. -L. Shang, H. -B. Cai +7

We present the results from the first quasi-simultaneous multi-frequency (2.3, 5.0, 8.4 and 15 GHz) Very Long Baseline Interferometry (VLBI) observations of a compact steep spectru…

Relation between radio core length and black hole mass for active galactic nuclei

Xinwu Cao, D. R. Jiang

We explore the relation between the linear length of radio core and the central black hole mass for a sample of radio-loud active galactic nuclei (AGNs). An empirical relation betw…

On the masses of black-holes in radio-loud quasars

Minfeng Gu, Xinwu Cao, D. R. Jiang

The central black-hole masses of a sample of radio-loud quasars are estimated by using the data of line-width and the optical continuum luminosity. The vast majority of the q…

Relation between blue/UV continuum shape and the ratio of radio to optical emission for B3-VLA quasars

Minfeng Gu, Xinwu Cao, D. R. Jiang +1

The low frequency radio luminosity is believed to be an indicator of jet power, while the optical/UV emission is probably from accretion discs in the nuclei of steep-spectrum radio…

The relation between extended radio and line emission for radio-loud quasars

Xinwu Cao, D. R. Jiang

We explore the relationship between the extended radio and line emission for a radio-loud quasar sample including both core-dominated and lobe-dominated quasars. A strong correlati…

Correlation between radio and broad-line emissions in radio-loud quasars

Xinwu Cao, D. R. Jiang

Radio emission is a good indicator of the jet power of radio-loud quasars, while the emission in broad-line can well represent the accretion disc radiation in quasars. We compile a…

Relation between millimeter wavelengths emission and high-energy emission for active galactic nuclei

L. H. Huang, D. R. Jiang, Xinwu Cao

After comparing the flux densities of a sample of active galactic nuclei detected by energetic gamma-ray experiment telescope at 90 and 230 GHz with the -ray emissions detected…
