Fundamental Plane of FSRQs from SDSS DR5 Quasar Catalogue
Ting-Ting Wang C.-Y. Su Z.-F. Chen Y.-P. Qin G.-A. Wang
In this work, we explore a sample of 362 flat-spectrum radio quasars (FSRQs) to investigate the jet formation. We find that the fundamental plane for our FSRQs can be expressed as 𝐿5\;GHz ∝ 𝑀$^{-0.19}_{\text{bh}}$ 𝐿$^{1.08}_{\text{2\; keV}}$. We also find that the 5 GHz luminosities are tightly related to both black hole mass and Eddington ratio, which is established as 𝐿5\;GHz ∝ 𝑀$^{0.67}_{\text{bh}}$ (𝐿bol/𝐿EDD)1.32.

Measurement of Black Hole Mass Radio-Loud Quasars
Cheng-Yue Su Z.-F. Chen R.-L. He C.-H. Zhang T.-T. Wang
In this work, we construct a sample of 1585 radio-loud quasars to measure their black hole masses using broad emission lines. We compare our black hole masses with the virial black hole masses measured by Shen

Continuous Article Publishing mode
Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
