The globular clusters and star formation history of the isolated, quiescent ultra-diffuse galaxy DGSAT I
Steven R. Janssens, Aaron J. Romanowsky, Roberto Abraham +6
We investigate the isolated, quiescent ultra-diffuse galaxy (UDG) DGSAT I and its globular cluster (GC) system using two orbits of Hubble Space Telescope Advanced Camera for Survey…
The PIPER Survey: I. An Initial Look at the Intergalactic Globular Cluster Population in the Perseus Cluster
William E. Harris, Rachel A. Brown, Patrick R. Durrell +7
We describe the goals and first results of a Program for Imaging of the PERseus cluster of galaxies (PIPER). The first phase of the program builds on imaging of fields obtained wit…
The Distribution of Ultra-Diffuse and Ultra-Compact Galaxies in the Frontier Fields
Steven R. Janssens, Roberto Abraham, Jean Brodie +2
Large low surface brightness galaxies have recently been found to be abundant in nearby galaxy clusters. In this paper, we investigate these ultra-diffuse galaxies (UDGs) in the si…
The Dragonfly Wide Field Survey. I. Telescope, Survey Design and Data Characterization
Shany Danieli, Deborah Lokhorst, Jielai Zhang +11
We present a description of the Dragonfly Wide Field Survey (DWFS), a deep photometric survey of a wide area of sky. The DWFS covers 330 in the equatorial GAMA fie…
The Maybe Stream: A Possible Cold Stellar Stream in the Ultra-Diffuse Galaxy NGC1052-DF2
Roberto Abraham, Shany Danieli, Pieter van Dokkum +10
We report tentative evidence for a cold stellar stream in the ultra-diffuse galaxy NGC1052-DF2. If confirmed, this stream (which we refer to as "The Maybe Stream") would be the fir…
The dragonfly nearby galaxies survey. Iv. A giant stellar disk in ngc 2841
Jielai Zhang, Roberto Abraham, Pieter van Dokkum +2
Neutral gas is commonly believed to dominate over stars in the outskirts of galaxies, and investigations of the disk-halo interface are generally considered to be in the domain of…
