A near-IR survey of luminous asymptotic giant branch stars in the satellites and stellar halo of M31
Jess M. Howell, Annette M. N. Ferguson, Olivia C. Jones +5
We investigate the dwarf spheroidal (dSph) satellites and stellar halo of M31 using near-infrared imaging from the Wide-Field Camera on the UKIRT 3.8 m telescope. Our homogeneous a…
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…
Characterising the Globular Cluster Systems of Three Local Group Dwarf Galaxies: NGC6822, NGC147 and NGC185
Gracie McGill, Annette M. N. Ferguson, Dougal Mackey +8
We present deep HST photometry for 26 globular clusters (GCs) residing in three Local Group dwarf galaxies: the isolated dwarf irregular (dIrr) galaxy, NGC6822, and the M31 dwarf e…
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…
