PHYSICAL REVIEW D   97(6)    Mar 2018   [Refereed]
We investigate gravitational redshifts (signals of gravitational potential) in measurements of the redshifts of cosmological objects, i.e., central and satellite galaxies in clusters of galaxies, intracluster gas, as well as galaxies associated wi...

PHYSICAL REVIEW D   95(2)    Jan 2017   [Refereed]
We investigate the quantum radiation produced by an Unruh-DeWitt detector in a uniformly accelerating motion coupled to the vacuum fluctuations. Quantum radiation is nonvanishing, which is consistent with the previous calculation by Lin and Hu [Ph...

PHYSICAL REVIEW D   95(4)    Feb 2017   [Refereed]
We present an analytic formula for the galaxy bispectrum in redshift space on the basis of the halo approach description with the halo occupation distribution of central galaxies and satellite galaxies. This work is an extension of a previous work...
