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…
Revisiting the enigmatic sixth star cluster in the Fornax dwarf spheroidal galaxy
Chiara Crociati, Annette M. N. Ferguson, Raffaele Pascale +7
The Fornax dwarf spheroidal (dSph) galaxy is one of only two Local Group dSphs that host a population of globular star clusters (GCs), the present-day properties of which have ofte…
A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE) XX. Star formation in the tidal tail of NGC 4254
A. Boselli, A. Lupi, P. Serra +26
ALMA 12CO(1-0) observations of 42 star-forming regions located outside the disc of the Virgo Cluster galaxy NGC4254 within an HI gas tail produced during the galaxy's interaction w…
Euclid: Early Release Observations -- The star-formation history of massive early-type galaxies in the Perseus cluster
S. Martocchia, A. Boselli, J. -C. Cuillandre +157
The Euclid Early Release Observations (ERO) programme targeted the Perseus galaxy cluster in its central region over 0.7deg. We combined the exceptional image quality and depth…
