TL;DR: In this article, the authors measured half-light radii for thousands of globular clusters (GCs) belonging to the 100 early-type galaxies observed in the ACS Virgo Cluster Survey and the elliptical galaxy NGC 4697.

TL;DR: The Very Large Array Sky Survey (VLASS) as discussed by the authors is a synoptic, all-sky radio sky survey with a unique combination of high angular resolution (≈2.5"), sensitivity (a 1σ goal of 70 μJy/beam in the coadded data), full linear Stokes polarimetry, time domain coverage, and wide bandwidth (2-4 GHz).

TL;DR: It is confirmed that nearby star-forming dwarf galaxies can indeed form massive black holes, and that by implication so can their primordial counterparts, and the lack of a substantial spheroidal component in Henize 2-10 indicates that supermassive black-hole growth may precede the build-up of galaxy spheroids.

TL;DR: In this article, the authors established a comprehensive database of black hole (and black hole candidate) X-ray binary (BHXB) activity between 1996 and 2015 as revealed by all-sky instruments, scanning surveys, and select narrow-field X -ray instruments aboard the INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL), Monitor of All-Sky Xray Image (MAXI), Rossi X-Ray Timing Explorer (RXTE), and Swift telescopes; the Whole-sky Alberta Time-resolved Comprehensive black-Hole Database Of the

TL;DR: In this article, the radio and X-ray emission of H1743−322 were investigated and it was shown that the inner accretion flow is radiatively efficient during the hard state, in contrast to what is usually assumed for black hole Xray binaries in this spectral state.
