The Milky Way has no in-situ halo other than the heated thick disc. Composition of the stellar halo and age-dating the last significant merger with Gaia DR2 and APOGEE
P. Di Matteo, M. Haywood, M. D. Lehnert +5
Previous studies based on the analysis of Gaia DR2 data have revealed that accreted stars, possibly originating from a single progenitor satellite, are a significant component of t…
The echo of the bar buckling: phase-space spirals in Gaia DR2
Sergey Khoperskov, Paola Di Matteo, Ortwin Gerhard +5
Using a single N-body simulation () we explore the formation, evolution and spatial variation of the phase-space spirals similar to those recently discovered by…
The Galactic warp revealed by Gaia DR2 kinematics
E. Poggio, R. Drimmel, M. G. Lattanzi +14
Using Gaia DR2 astrometry, we map the kinematic signature of the Galactic stellar warp out to a distance of 7 kpc from the Sun. Combining Gaia DR2 and 2MASS photometry, we identify…
Gaia Data Release 2: Mapping the Milky Way disc kinematics
Gaia Collaboration, D. Katz, T. Antoja +12
To illustrate the potential of GDR2, we provide a first look at the kinematics of the Milky Way disc, within a radius of several kiloparsecs around the Sun. We benefit for the firs…
