An enigmatic 380 kpc long linear collimated galactic tail
Dennis Zaritsky,Jacob P. Crossett,Richard L. Donnerstein,Ananthan Karunakaran,Donghyeon J. Khim,A. C. C. Lourenço,Kristine Spekkens,Ming Sun,Benedetta Vulcani +8 more
TL;DR: In this article , a serendipitously-detected system consisting of an S 0/a galaxy, referred to as the Kite, and a highly-collimated tail of gas and stars that extends over 380kpc and contains pockets of star formation is presented.

Resolving the Metallicity Distribution of the Stellar Halo with the H3 Survey
Charlie Conroy,Rohan P. Naidu,Dennis Zaritsky,Ana Bonaca,Phillip A. Cargile,Benjamin D. Johnson,Nelson Caldwell +6 more
TL;DR: In this article, the distribution of stellar metallicities as a function of Galactocentric distance and orbital properties for a sample of 4232 kinematically-selected halo giants to 100 kpc is presented.
Signatures of Tidal Disruption in Ultra-Faint Dwarf Galaxies: A Combined HST, Gaia, and MMT/Hectochelle Study of Leo V

TL;DR: In this paper, a combination of high-precision photometry obtained with the Hubble Space Telescope (HST), two epochs of stellar spectra obtained with Hectochelle Spectrograph on the MMT, and measurements from the Gaia mission is used to examine one of the reported stream-like overdensities at large radii and conclude that it is not a true stellar stream, but instead a clump of foreground stars and background galaxies.

A photometric search for transients in galaxy clusters
TL;DR: In this article, the authors used the 2.3m Bok Telescope on Kitt Peak to search for supernovae and other transients in the fields of galaxy clusters with photometric methods.
