Search for Quasar Pairs with Astrometric Data. III. Discovery of 9 dual and projected quasars
Qihang Chen, Zizhao He, Zhuojun Deng +3
We report the low-resolution long-slit spectroscopic observations and confirmations of 11 quasar pair candidates, which are selected from the MGQPC catalog presented in the first p…
Search for quasar pairs with Gaia astrometric data. II. Photometric redshift prediction with machine learning for the MGQPC catalogue
Xingyu Zhu, Qihang Chen, Liang Jing +4
The identification of physically associated kiloparsec-scale quasar pairs is important for understanding galaxy evolution, the growth of supermassive black holes, and their co-evol…
Search for quasar pairs with Gaia astrometric data IV. Confirmation of 17 dual quasars and 143 projected quasars
Zhuojun Deng, Qihang Chen, Liang Jing +2
Dual quasars separated at the kiloparsec scale are widely regarded as precursors to binary supermassive black holes and offer a key insight into the dynamical evolution of galaxy m…
Dual AGNs on 100 kpc Scales from the Million Quasar Catalog
Zhuojun Deng, Cheng Xiang, Qihang Chen +3
Research on dual active galactic nuclei (AGNs) is crucial for understanding the coevolution of galaxies and supermassive black holes. However, the current number of dual AGNs remai…
On type 1 active galactic nuclei with double-peaked [O~{\sc iii}]. II. properties of long-term optical variability
Qi Zheng, Xingyv Zhu, Xueguang Zhang +1
Double-peaked \oiii~profiles could potentially indicate kiloparsec-scale dual AGNs. We analyze long-term optical light curves of 35 type 1 AGNs with such features from our recent c…
A Quasar Pair Sample Compiled from DESI DR1
Liang Jing, Qihang Chen, Zhuojun Deng +4
Interacting quasar pairs (QPs, either dual or binary) provide crucial insights into galaxy mergers, black hole growth, and large-scale structure formation. The current literature r…
Search for Quasar Pairs with Astrometric Data. I. Method and Candidates
Qihang Chen, Liang Jing, Xingyu Zhu +5
Quasar pairs, a special subclass of galaxy pairs, are valuable in the investigation of quasar interaction, clustering, co-evolution between the two quasars' host galaxies, the grow…
SDSS J1042-0018 a broad line AGN but mis-classified as a HII galaxy in the BPT diagram by flux ratios of narrow emission lines
Cao Yi, Zhao SiDan, Zhu XingYu +3
In the manuscript, we discuss properties of the SDSS J1042-0018 which is a broad line AGN but mis-classified as a HII galaxy in the BPT diagram (SDSS J1042-0018 called as a mis-cla…
