Evidence for the First Globular Cluster Stellar Stream beyond the Milky Way
Julie Kiel Holm, Sarah Pearson, Jacob Nibauer +5
The dark matter content of ultra-diffuse galaxies is the subject of considerable debate. Stellar streams, which form when a host galaxy tidally strips stars from an orbiting stella…
Fresh Insights on the Kinematics of M49's Globular Cluster System with MMT/Hectospec Spectroscopy
Matthew A. Taylor, Youkyung Ko, Patrick Côté +10
We present the first results of an MMT/Hectospec campaign to measure the kinematics of globular clusters (GCs) around M49 -- the brightest galaxy in the Virgo galaxy cluster, which…
The Dragonfly Edge-on Galaxies Survey: Shaping the outer disc of NGC 4565 via accretion
Colleen Gilhuly, David Hendel, Allison Merritt +6
We present extremely deep imaging of the well-known edge-on galaxy NGC 4565 (the "Needle Galaxy"), observed as part of the Dragonfly Edge-on Galaxies Survey. Our imaging traces sta…
LSST Cadence Optimization White Paper in Support of Observations of Unresolved Tidal Stellar Streams in Galaxies beyond the Local Group
Seppo Laine, David Martinez-Delgado, Ignacio Trujillo +11
Deep observations of faint surface brightness stellar tidal streams in external galaxies with LSST are addressed in this White Paper contribution. We propose using the Wide--Fast--…
The total mass of the Large Magellanic Cloud from its perturbation on the Orphan stream
D. Erkal, V. Belokurov, C. F. P. Laporte +13
In a companion paper by Koposov et al., RR Lyrae from \textit{Gaia} Data Release 2 are used to demonstrate that stars in the Orphan stream have velocity vectors significantly misal…
Piercing the Milky Way: an all-sky view of the Orphan Stream
S. E. Koposov, V. Belokurov, T. S. Li +13
We use astrometry, broad-band photometry and variability information from the Data Release 2 of ESA's Gaia mission (GDR2) to identify members of the Orphan Stream (OS) across the w…
