TL;DR: Hosek et al. as mentioned in this paper used multi-epoch Hubble Space Telescope observations to obtain high-precision proper-motion and photometric measurements of the Arches cluster, calculating cluster membership probabilities for stars down to ∼1.8 M o between cluster radii of 0.25 and 3.0 pc.

TL;DR: Hosek et al. as mentioned in this paper used the Hubble Space Telescope observations to measure the optical and near-infrared extinction law (0.8-2.2 μm), which is consistent with a single power law, even when only the nearinfrared filters are considered, and has A F125W/A Ks and A F814W/a Ks values that are 18% and 24% higher than the commonly used Nishiyama et al., respectively.

TL;DR: In this paper, the authors use multi-epochamber Hubble Space Telescope observations to obtain high-precision proper motion and photometric measurements of the Arches cluster, calculating cluster membership probabilities for stars down to 1.8.

TL;DR: In this article, the authors present homogeneous, sub-horizontal branch photometry of twenty dwarf spheroidal satellite galaxies of M31 observed with the Hubble Space Telescope.

TL;DR: In this article, the star formation histories (SFHs) of 20 faint M31 satellites were measured by modeling sub-horizontal branch (HB) depth color-magnitude diagrams constructed from Hubble Space Telescope (HST) imaging.
