Anomalous anisotropic cross-correlations between WMAP CMB maps and SDSS galaxy distribution and implications on the dark flow scenario
Zhigang Li, Pengjie Zhang, Xuelei Chen
We search for the dark flow induced diffuse kinetic Sunyaev Zel'dovich (kSZ) effect through CMB-galaxy cross correlation. Such angular correlation is anisotropic, with a unique $co…

Type Ia supernovae as speed sensors at intermediate redshifts
Pengjie Zhang, Xuelei Chen
The application of large scale peculiar velocity (LSPV), as a crucial probe of dark matter, dark energy and gravity, is severely limited by measurement obstacles. We show that fluc…

Detecting First Star Lyman- Spheres through Gravitational Telescopes
Guoliang Li, Pengjie Zhang, Xuelei Chen
Lyman- spheres, i.e. regions around the first stars which are illuminated by Lyman- photons and show 21cm absorption feature against the CMB, are smoking guns at the dawn of…
