Simulating the galaxy cluster "El Gordo" and identifying the merger configuration
Congyao Zhang, Qingjuan Yu, Youjun Lu
The observational features of the massive galaxy cluster "El Gordo" (ACT-CL J0102-4915), such as the X-ray emission, the Sunyaev-Zel'dovich (SZ) effect, and the surface mass densit…

On Testing the Kerr Metric of the Massive Black Hole in the Galactic Center via Stellar Orbital Motion: Full General Relativistic Treatment
Fupeng Zhang, Youjun Lu, Qingjuan Yu
The S-stars in the Galactic center (GC) are anticipated to provide unique dynamical constraint on the spin of the GC massive black hole (MBH). In this paper, we develop a fast full…
