NGC5846-UDG1: A galaxy formed mostly by star formation in massive, extremely dense clumps of gas
Shany Danieli, Pieter van Dokkum, Sebastian Trujillo-Gomez +10
It has been shown that ultra-diffuse galaxies (UDGs) have higher specific frequencies of globular clusters on average than other dwarf galaxies with similar luminosities. The UDG N…
A Method To Characterize the Wide-Angle Point Spread Function of Astronomical Images
Qing Liu, Roberto Abraham, Colleen Gilhuly +14
Uncertainty in the wide-angle Point Spread Function (PSF) at large angles (tens of arcseconds and beyond) is one of the dominant sources of error in a number of important quantitie…
Reaching for the Edge I: Probing the Outskirts of Massive Galaxies with HSC, DECaLS, SDSS, and Dragonfly
Jiaxuan Li, Song Huang, Alexie Leauthaud +9
The outer light (stellar halos) of massive galaxies has recently emerged as a possible low scatter tracer of dark matter halo mass. To test the robustness of outer light measuremen…
Tidal Distortions in NGC1052-DF2 and NGC1052-DF4: Independent Evidence for a Lack of Dark Matter
Michael A. Keim, Pieter van Dokkum, Shany Danieli +11
Two ultra diffuse galaxies in the same group, NGC1052-DF2 and NGC1052-DF4, have been found to have little or no dark matter and to host unusually luminous globular cluster populati…
