Milky Way disc & Bulge in situ populations: ESO white paper - Expanding horizons call
M. Bergemann, G. Kordopatis, G. Casali +11
The formation and evolution of the Milky Way's disc, bar, and bulge remain fundamentally limited by the lack of a contiguous, Galaxy-wide, high-precision chemo-dynamical map. Key o…
GaiaUnlimited: The old stellar disc of the Milky Way as traced by the Red Clump
Shourya Khanna, Jie Yu, Ronald Drimmel +9
We present an exploration of the Milky Way's structural parameters using an all-sky sample of RC giants to map the stellar density from the Galactic disc beyond 3 kpc. These evolve…
Metal-rich stellar counterpart of the Radcliffe Wave and the 3D chemical footprints of the Milky Way spiral arms
Luis Martinez-Medina, Eloisa Poggio, Elizabeth Moreno-Hilario
Mapping the Milky Way spiral arms in the vertical direction remains a challenging task that has received little attention. Taking advantage of recent results that link the position…
The Milky Way as Seen by Classical Cepheids II: Spiral Structure
Ronald Drimmel, Shourya Khanna, Eloisa Poggio +1
As a relatively young and bright population and the archetype of standard candles, classical Cepheids are an ideal population on which to trace the non-axisymmetric structure in th…
The Milky Way as Seen by Classical Cepheids I: Distances Based on Mid-infrared Photometry
Dorota M. Skowron, Ronald Drimmel, Shourya Khanna +3
Classical Cepheids are the archetype of the standard candle, thanks to the period-luminosity relation which allows to measure their intrinsic brightness. They are also relatively y…
The Great Wave: Evidence of a large-scale vertical corrugation propagating outwards in the Galactic disc
E. Poggio, S. Khanna, R. Drimmel +6
We analyse the three-dimensional structure and kinematics of two samples of young stars in the Galactic disc, containing respectively young giants (17000 stars out to he…
