Modeling features in the redshift-space halo power spectrum with perturbation theory
TL;DR: In this paper, the ability of perturbative models with effective field theory contributions and infra-red resummation to model the redshift space clustering of biased tracers in models where the linear power spectrum has "features" was studied.
Journal ArticleDOI
The BINGO project
TL;DR: The Baryon Acoustic Oscillations from Integrated Neutral Gas Observations (BINGO) radio telescope as discussed by the authors is an instrument designed to detect baryonic acoustic oscillations (BAOs) in the cosmological H I signal, in the redshift interval 0.127 ≤ z ≤ 0.449.

Impact of radio sources and cosmic infrared background on thermal Sunyaev-Zel'dovich - gravitational lensing cross-correlation
TL;DR: In this article, the impact of radio sources and cosmic infrared background (CIB) on observed tSZ-lensing correlation was studied. And the authors showed that the residual correlation of CIB with large-scale structures will be of an order of $2\%$ of expected TSZ lensing correlation from intracluster medium in current lensing surveys.
Journal ArticleDOI
Wide-angle effects for peculiar velocities
TL;DR: Castorina et al. as mentioned in this paper studied how wide-angle effects modify the predicted correlation function and power spectrum for momentum statistics, both in auto-correlation and in crosscorrelation with the density field.
Journal ArticleDOI
Covariance matrices for galaxy cluster weak lensing: from virial regime to uncorrelated large-scale structure
TL;DR: In this article, a combination of analytical calculations and high-resolution N-body simulations is used to derive accurate covariance matrices that span from the virial regime to linear scales of the cluster-matter cross-correlation.

The relationship between infrared, optical, and ultraviolet extinction
TL;DR: In this article, the average extinction law over the 3.5 micron to 0.125 wavelength range was derived for both diffuse and dense regions of the interstellar medium. And the validity of the law over a large wavelength interval suggests that the processes which modify the sizes and compositions of grains are stochastic in nature.
