Strange Quasar Candidates with Abnormal Astrometric Characteristics from Gaia EDR3 and SDSS (SQUAB-II): Optical Identifications

Xiang Ji, Zhen-Ya Zheng, Qiqi Wu +7

There are some strange quasars with multiple Gaia detections or observed with abnormal astrometric characteristics, such as with large proper motions or significant astrometric noi…

Discovery of Five Green Pea Galaxies with Double-peaked Narrow [OIII] Lines

Ruqiu Lin, Zhen-Ya Zheng, Jun-Xian Wang +9

Although double-peaked narrow emission-line galaxies have been studied extensively in the past years, only a few are reported with the green pea galaxies (GPs). Here we present our…

SQUAB I: The first release of Strange QUasar candidates with ABnormal astrometric characteristics from Gaia EDR3 and SDSS

Qi-Qi Wu, Shi-Long Liao, Xiang Ji +4

Given their extremely large distances and small apparent sizes, quasars are generally considered as objects with near-zero parallax and proper motion. However, some special quasars…

Variations of Broad Emission Lines from periodicity QSOs under the interpretation of supermassive binary black holes with misaligned circumbinary broad line regions

Xiang Ji, Junqiang Ge, Youjun Lu +1

Quasars with periodic light curves are considered as candidates of supermassive binary black hole (BBH) systems. One way for further confirmations may be searching for other charac…

Variation of Broad Emission Lines from QSOs with Optical/UV Periodicity to Test the Interpretation of Supermassive Binary Black Holes

Xiang Ji, Youjun Lu, Junqiang Ge +2

Periodic quasars have been suggested to host supermassive binary black holes (BBHs) in their centers, and their optical/UV periodicities are interpreted as caused by either the Dop…

Broad-line region configuration of the supermassive binary black hole candidate PG1302-102 in the relativistic Doppler boosting scenario

Zihao Song, Junqiang Ge, Youjun Lu +2

PG1302-102 is thought to be a supermassive binary black hole (BBH) system according to the periodical variations of its optical and UV photometry, which may be interpreted as being…

Galaxy Optical Variability of Virgo Cluster: New Tracer for Environmental Influences on Galaxies

Fan Yang, Richard J. Long, Su-Su Shan +6

We investigate the relationship between the optical variability of galaxies and their distances from the centre of the Virgo Cluster using Palomar Transient Factory data. We define…

Testing the relativistic Doppler boost hypothesis for supermassive binary black holes candidates via broad emission line profiles

Zihao Song, Junqiang Ge, Youjun Lu +1

Optical periodicity QSOs found by transient surveys are suggested to be sub-parsec supermassive binary black holes (BBHs). An intriguing interpretation for the periodicity of some…
