Supercritical McKean-Vlasov SDE driven by cylindrical $\alpha$-stable process

Autor: Hao, Zimo, Ren, Chongyang, Wu, Mingyan

In this paper, we study the following supercritical McKean-Vlasov SDE, driven by a symmetric non-degenerate cylindrical $\alpha$-stable process in $\mathbb{R}^d$ with $\alpha \in (0,1)$: $$ \mathord{{\rm d}} X_t = (K * \mu_{t})(X_t)\mathord{{\rm d}}t

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

Autor: Zeng, Lujun, Zhang, Mengqing, Ren, Chongyang, Zhang, Pengfei, Yan, Jingzhi

LS 5039 is one of a handful of $\gamma$-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 conducted a data analysis using approximately 16 year of Fermi-LAT ob

Heat kernel estimates for kinetic SDEs with drifts being unbounded and in Kato's class

Autor: Ren, Chongyang, Zhang, Xicheng

In this paper we investigate the existence and uniqueness of weak solutions for kinetic stochastic differential equations with H\"older diffusion and unbounded singular drifts in Kato's class. Moreover, we also establish sharp two-sided estimates for

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

Autor: Ren, Chongyang, Sun, Sisi, Zhang, Pengfei

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 redshift of 1.34 with the data from the Zwicky Transient Facility (ZTF)
