The effect of aberration on partial-sky measurements of the cosmic microwave background temperature power spectrum
Donghui Jeong, Jens Chluba, Liang Dai +2
Our motion relative to the cosmic-microwave-background (CMB) rest frame deflects light rays giving rise to shifts as large as L -> L(1+beta), where beta=0.00123 is our velocity (in…
Reconstructing primordial power spectrum using Planck and SDSS-III measurements
Xin Wang, Gong-Bo Zhao
We develop an accurate and efficient Bayesian method to reconstruct the primordial power spectrum in a model-independent way, and apply it to the latest cosmic microwave background…
Kinematic Morphology of Large-scale Structure: Evolution from Potential to Rotational Flow
Xin Wang, Alex Szalay, Miguel A. Aragon-Calvo +2
As an alternative way of describing the cosmological velocity field, we discuss the evolution of rotational invariants constructed from the velocity gradient tensor. Compared with…
BSG alignment of SDSS galaxy groups
Zhigang Li, Yougang Wang, Xiaohu Yang +3
We study the alignment signal between the distribution of brightest satellite galaxies (BSGs) and the major axis of their host groups using SDSS group catalog constructed by Yang e…
