TL;DR: In this article, the authors present estimates of stellar population (SP) gradients from stacked spectra of slow (SR) and fast (FR) rotator elliptical galaxies from the MaNGA-DR15 survey.

TL;DR: In this article, an analytic expression for the n-point joint PDF of the SZ power spectrum was derived based on the halo model, which is expressed in an integral form and is applicable to any given survey and any given angular scale.

TL;DR: In this article, a new way of looking at the Baryon Acoustic Oscillation in the large-scale-structure clustering correlation function is proposed, which is called the linear point.

TL;DR: In this article, the authors proposed a survey of under-dense regions of the universe, where the effects of gravity modifications are expected to be more prominent, and provided an unprecedented opportunity to observe and study a so far under-explored galaxy population.

TL;DR: Skibba et al. as mentioned in this paper used mark correlation functions to detect a small dependence of galaxy properties on the environment, quantified by the overdensity 1 + δ, which is difficult to detect by traditional methods, and showed that rank ordering the marks and using the rank as a weight is a simple way of comparing the correlation signals for different marks.
