The SDSS Galaxy Angular Two-Point Correlation Function [PDF]

, 2013
We present the galaxy two-point angular correlation function for galaxies selected from the seventh data release of the Sloan Digital Sky Survey. The galaxy sample was selected with r-band apparent magnitudes between 17 and 21; and we measure the ...

Primary Current Test Method for Transformer Protection Based on Transient Load

Zhongguo dianli, 2021
When test load is insufficient, the current transformer (TA) secondary circuit test by primary current cannot be completed, which often results in the failure of new transformer protection to be put into normal operation.

Detection of the Baryon Acoustic Peak in the Large-Scale Correlation Function of SDSS Luminous Red Galaxies [PDF]

, 2005
We present the large-scale correlation function measured from a spectroscopic sample of 46,748 luminous red galaxies from the Sloan Digital Sky Survey. The survey region covers 0.72 h-3 Gpc3 over 3816 deg2 and 0.16 < z < 0.47, making it the best sample ...

Effect of Mth coherent state on the interaction between two two-level atoms and two-mode quantized field

Journal of Taibah University for Science, 2022
The objective of this work is to measure the influence of the Mth coherent state on the optics model of two atoms interacting with two-mode quantized field. Also, two atoms interacting together is included in this optics model.

The Aemulus Project. III. Emulation of the Galaxy Correlation Function [PDF]

Astrophysical Journal, 2018
Using the N-body simulations of the Aemulus Project, we construct an emulator for the nonlinear clustering of galaxies in real and redshift space. We construct our model of galaxy bias using the halo occupation framework, accounting for possible velocity

Baryon acoustic oscillations from the complete SDSS-III Ly$\alpha$-quasar cross-correlation function at $z=2.4$ [PDF]

, 2017
We present a measurement of baryon acoustic oscillations (BAO) in the cross-correlation of quasars with the Lyα-forest flux transmission at a mean redshift of z = 2.40.

Correlation function diagnostics for type-I fracton phases [PDF]

, 2017
Fracton phases are recent entrants to the roster of topological phases in three dimensions. They are characterized by subextensively divergent topological degeneracy and excitations that are constrained to move along lower dimensional subspaces ...
