Measurement of redshift dependent cross correlation of HSC clusters and Fermi $\gamma$ rays [PDF]

, 2019
The cross-correlation study of the unresolved $\gamma$-ray background (UGRB) with galaxy clusters has a potential to reveal the nature of the UGRB. In this paper, we perform a cross-correlation analysis between $\gamma$-ray data by the Fermi Large Area ...

Variable G versus the Accelerated Expansion of the Universe

Open Astronomy, 2017
It is shown that the hypothesis of permitting variability of the Newtonian constant G, increasing with the local density of dark matter, implies that there is no need for the introduction of a cosmological constant or accelerated expansion of the ...

The VIMOS VLT Deep Survey: Evolution of the non-linear galaxy bias up to z=1.5 [PDF]

, 2005
We present the first measurements of the Probability Distribution Function (PDF) of galaxy fluctuations in the VIMOS-VLT Deep Survey (VVDS) cone, covering 0.4x0.4 deg between 0 ...

Redshifting rings of power [PDF]

Physical Review D, 2003
The cosmic microwave background (CMB) has provided a precise template for features in the linear power spectrum: the matter-radiation turnover, sound horizon drop, and acoustic oscillations. In a two dimensional power spectrum in redshift and angular space, the features appear as distorted rings, and yield simultaneous, purely geometric, measures of ...

Baryon Acoustic Oscillations in 2D: Modeling Redshift-space Power Spectrum from Perturbation Theory [PDF]

, 2010
We present an improved prescription for matter power spectrum in redshift space taking a proper account of both the non-linear gravitational clustering and redshift distortion, which are of particular importance for accurately modeling baryon acoustic ...

Status of racial disparities between black and white women undergoing assisted reproductive technology in the US

Reproductive Biology and Endocrinology, 2020
Background Numerous studies have demonstrated substantial differences in assisted reproductive technology outcomes between black non-Hispanic and white non-Hispanic women. We sought to determine if disparities in assisted reproductive technology outcomes
