The particle surface of spinning test particles
Yong Song, Yiting Cen, Leilei Tang +4
In this work, inspired by the definition of the photon surface given by Claudel, Virbhadra, and Ellis, we give an alternative quasi-local definition to study the circular orbits of…
Quasi-local studies of the particle surfaces and their stability in general spacetimes
Yong Song, Chuanyu Zhang
In this paper, enlightened by the definition of the photon surface given by Claudel, Virbhadra and Ellis, we give a quasi-local definition of the particle surface. From this defini…
The evolutions of the innermost stable circular orbits in dynamical spacetimes
Yong Song
In this paper, we studied the evolutions of the innermost stable circular orbits (ISCOs) in dynamical spacetimes. At first, we reviewed the method to obtain the ISCO in Schwarzschi…
Toward a more stringent test of gravity with redshift space power spectrum: simultaneous probe of growth and amplitude of large-scale structure
Yong-Seon Song, Yi Zheng, Atsushi Taruya
Redshift-space distortions (RSD) offers an exciting opportunity to test the gravity on cosmological scales. In the presence of galaxy bias, however, the RSD measurement at large sc…
HIR4: Cosmological signatures imprinted on the cross correlation between 21-cm map and galaxy clustering
Feng Shi, Yong-Seon Song, Jacobo Asorey +5
We explore the cosmological multitracer synergies between an emission line galaxy distribution from the Dark Energy Spectroscopic Instrument and a Tianlai Project 21-cm intensity m…
The clustering of LRGs in the DECaLS DR8 footprint: distance constraints from baryon acoustic oscillations using photometric redshifts
Srivatsan Sridhar, Yong-Seon Song, Ashley J. Ross +7
A photometric redshift sample of Luminous Red Galaxies (hereafter LRGs) obtained from The DECam Legacy Survey (DECaLS) is analysed to probe cosmic distances by exploiting the wedge…
