galstreams: A Library of Milky Way Stellar Stream Footprints and Tracks
Cecilia Mateu
Nearly a hundred stellar streams have been found to date around the Milky Way and the number keeps growing at an ever faster pace. Here we present the galstreams library, a compend…
The Sagittarius stream in Gaia eDR3 and the origin of the bifurcations
P. Ramos, T. Antoja, Z. Yuan +6
The Sagittarius dwarf spheroidal (Sgr) is a dissolving galaxy being tidally disrupted by the Milky Way (MW). Its stellar stream still poses serious modelling challenges, which hind…
The RR Lyrae Delay-Time Distribution: A Novel Perspective on Models of Old Stellar Populations
Sumit K. Sarbadhicary, Mairead Heiger, Carles Badenes +6
The delay-time distribution (DTD) is the occurrence rate of a class of objects as a function of time after a hypothetical burst of star formation. DTDs are mainly used as a statist…
The outer disc in shambles: blind detection of Monoceros and ACS with Gaia's astrometric sample
P. Ramos, T. Antoja, C. Mateu +5
The astrometric sample of Gaia allows us to study the outermost Galactic disc, the halo and their interface. It is precisely at the very edge of the disc where the effects of exter…
Revealing the Structure and Internal Rotation of the Sagittarius Dwarf Spheroidal Galaxy with Gaia and Machine Learning
Andrés del Pino, Mark A. Fardal, Roeland P. van der Marel +3
We present a detailed study of the internal structure and kinematics of the core of the Sagittarius dwarf spheroidal galaxy (Sgr). Using machine-learning techniques, we have combin…
Discovery of Extended Tidal Tails around the Globular Cluster Palomar 13
Nora Shipp, Adrian Price-Whelan, Kiyan Tavangar +2
We use photometry from the DECam Legacy Survey to detect candidate tidal tails extending ~5 deg on either side of the Palomar 13 globular cluster. The tails are aligned with the pr…
