Integrated Optical Polarization of nearby Galaxies
TL;DR: In this paper, the authors performed an integrated optical polarization survey of 70 nearby galaxies to study the relationship between linear polarization and galaxy properties and found that dust scattering is the main source of optical polarization.

The Baryon Fraction in the Perseus Cluster: Results from Spartan 1
Raymond G. Cruddace,Michael P. Kowalski,G. G. Fritz,W. A. Snyder,E. E. Fenimore,Melville P. Ulmer +5 more
TL;DR: In this article, X-ray observations of the Perseus cluster in the 1-10 keV band were made by the Spartan 1 instrument, which revealed that the dark matter comprises 60% of the total mass and is concentrated toward the cluster center.

Large scale extinction maps with UVIT
TL;DR: In this paper, the authors studied the efficacy of UVIT observations for interstellar extinction measurements and found that in the best case scenario, the UVIT can measure the reddening to an accuracy of about 0.02 magnitudes, which combined with the derived distances to the stars, will enable the three-dimensional distribution of extinction in our Galaxy.

TL;DR: In this paper, a detailed study of the F-type detached eclipsing binary BK Peg, based on new photometric and spectroscopic observations, is presented, where the two components, which have evolved to the upper half of the main-sequence band, are quite different with masses and radii of (1.414 +/- 0.007 Msun, 1.988 +/- 0.,008 Rsun) and (1257 +/- 0,017 Rsun), respectively.

Sizing up the milky way: a bayesian mixture model meta-analysis of photometric scale length measurements
TL;DR: In this paper, a Bayesian meta-analysis was performed to determine an improved, aggregate estimate for the exponential scale length of the Milky Way's (MW's) disk, utilizing a mixture-model approach to account for the possibility that any one measurement has not properly accounted for all statistical or systematic errors.
