We report the first detection of the `convective-transition gap' (also known as `M-dwarf gap') in the globular cluster 47 Tuc (NGC 104) thanks to Euclid data. This feature, linked…

Hidden deep in the halo: selection of a reduced proper motion halo catalogue and mining retrograde streams in the velocity space
Akshara Viswanathan, Else Starkenburg, Helmer H. Koppelman +3
The Milky Way halo is one of the few galactic haloes that provides a unique insight into galaxy formation by resolved stellar populations. Here, we present a catalogue of 47…
