Investigating the Potential of LS 5039 as a Triple System Using Fermi-LAT Data

Lujun Zeng, Mengqing Zhang, Chongyang Ren +2

LS 5039 is one of a handful of $γ$ -ray binary systems in the Milky Way, comprising a pulsar and a massive O-type companion star with an orbital period of 3.9 day. Recently, we cond…

A Possible Optical Quasi-periodic Oscillation of 134~day in the Radio-loud Narrow-line Seyfert 1 Galaxy TXS 1206+549 at $z = 1.34$

Chongyang Ren, Sisi Sun, Pengfei Zhang

Here we report an optical quasi-periodic oscillation (QPO) with a period of $\sim$ 134~day detected in g- and r-band light curves of a narrow-line Seyfert 1 galaxy TXS 1206+549 at r…
