SDSS-IV MaNGA: Radial Gradients in Stellar Population Properties of Early-Type and Late-Type Galaxies
Age gradients in LTGs steepen with increasing galaxy mass, from $-0. 05\pm0. 11~\log$ Gyr/R$_e$ for the lowest mass galaxies to $-0. 82\pm0. 08~\log$ Gyr/R$_e$ for the highest mass ones.

Dark Energy Survey Year 1 Results: Cosmological Constraints from Cluster Abundances and Weak Lensing
We perform a joint analysis of the counts and weak lensing signal of redMaPPer clusters selected from the Dark Energy Survey (DES) Year 1 dataset.

The Data Analysis Pipeline for the SDSS-IV MaNGA IFU Galaxy Survey: Overview
We summarize assessments of the precision and accuracy of our measurements as a function of signal-to-noise and other salient metrics, noting that additional analysis and discussion of emission-line diagnostics are provided in our companion paper, Belfiore et al.

Predicting pregnancy using large-scale data from a women's health tracking mobile application
Predicting pregnancy has been a fundamental problem in women's health for more than 50 years.
The clustering of galaxies in the completed SDSS-III Baryon Oscillation Spectroscopic Survey: cosmological analysis of the DR12 galaxy sample
When combined with supernova Ia data, we find H0 = 67. 3+/-1. 0 km/s/Mpc even for our most general dark energy model, in tension with some direct measurements.

The clustering of galaxies in the completed SDSS-III Baryon Oscillation Spectroscopic Survey: tomographic BAO analysis of DR12 combined sample in configuration space
Splitting the sample into multiple overlapping redshift slices to extract the redshift information of galaxy clustering, we obtain a measurement of $D_A(z)/r_d$ and $H(z)r_d$ at nine effective redshifts with the full covariance matrix calibrated using MultiDark-Patchy mock catalogues.

SDSS-III Baryon Oscillation Spectroscopic Survey Data Release 12: galaxy target selection and large scale structure catalogues
We also present the algorithms used to create large scale structure catalogues for the final Data Release (DR12) samples and the associated random catalogues that quantify the survey mask.

Overview of the SDSS-IV MaNGA Survey: Mapping Nearby Galaxies at Apache Point Observatory
MaNGA will investigate the internal kinematic structure and composition of gas and stars in an unprecedented sample of 10, 000 nearby galaxies.
The Clustering of Galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: Measuring H(z) and D_A(z) at z = 0.57 with Clustering Wedges
The baryonic acoustic feature is used to obtain model independent constraints cz/H/r_s = 12. 28 +- 0. 82 (6. 7 per-cent accuracy) and D_A/r_s = 9. 05 +- 0. 27 (3. 0 per-cent) with a correlation coefficient of -0. 5, where r_s is the sound horizon scale at the end of the baryonic drag era.
