Position-dependent power spectrum: a new observable in the large-scale structure
Chi-Ting Chiang
We present a new observable, position-dependent power spectrum, to measure the large-scale structure bispectrum in the squeezed configuration, where one wavenumber is much smaller…
Surveying Galaxy Proto-clusters in Emission: A Large-scale Structure at z=2.44 and the Outlook for HETDEX
Yi-Kuan Chiang, Roderik A. Overzier, Karl Gebhardt +12
Galaxy proto-clusters at z >~ 2 provide a direct probe of the rapid mass assembly and galaxy growth of present day massive clusters. Because of the need of precise galaxy redshifts…
Position-dependent correlation function from the SDSS-III Baryon Oscillation Spectroscopic Survey Data Release 10 CMASS Sample
Chi-Ting Chiang, Christian Wagner, Ariel G. Sánchez +2
We report on the first measurement of the three-point function with the position-dependent correlation function from the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS) Dat…
The angle-averaged squeezed limit of nonlinear matter N-point functions
Christian Wagner, Fabian Schmidt, Chi-Ting Chiang +1
We show that in a certain, angle-averaged squeezed limit, the -point function of matter is related to the response of the matter power spectrum to a long-wavelength density pert…
