Euclid: Data Release 1 (DR1) -- Fornax-7, an ultra-faint companion to the Fornax dwarf spheroidal galaxy? A remote star cluster or dwarf satellite of the Fornax dSph

T. Saifollahi, A. Lançon, A. M. N. Ferguson +165

We report the discovery of an ultra-faint stellar system in the vicinity of the Fornax dwarf spheroidal (dSph) galaxy in Euclid DR1. This system, which we designate Fornax-7, is lo…

Euclid: The convective-transition gap of 47 Tuc

M. Libralato, M. Griggio, R. Gerasimov +140

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…

Euclid: Early Release Observations -- Internal kinematics and the convective-transition gap of NGC 6397

M. Griggio, M. Libralato, R. Gerasimov +130

We present a 'multiple-pass' data-reduction tool designed for Euclid, based on software developed for the Hubble Space Telescope (HST), which improves the astrometric and photometr…

Low surface brightness dwarf galaxies and their globular cluster populations around the low-density environment of our closest S0 NGC3115

Marco A. Canossa-Gosteinski, Ana L. Chies-Santos, Cristina Furlanetto +12

Understanding faint dwarf galaxies is fundamental to the development of a robust theory of galaxy formation on small scales. Since the discovery of a population of ultra diffuse ga…

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…

Dynamics in the outskirts of four Milky Way globular clusters: it's the tides that dominate

Zhen Wan, Anthony D. Arnold, William H. Oliver +17

We present the results of a spectroscopic survey of the outskirts of 4 globular clusters -- NGC 1261, NGC 4590, NGC 1904, and NGC 1851 -- covering targets within 1 degree from the…
