RomAndromeda: The Roman Survey of the Andromeda Halo
Arjun Dey, Joan Najita, Carrie Filion +50
As our nearest large neighbor, the Andromeda Galaxy provides a unique laboratory for investigating galaxy formation and the distribution and substructure properties of dark matter…
Pisces VII/Triangulum III -- M33's second dwarf satellite galaxy
Michelle L. M. Collins, Noushin Karim, David Martinez-Delgado +6
Pisces VII/Triangulum III (Pisc~VII) was discovered in the DESI Legacy Imaging Survey and was shown to be a Local Group dwarf galaxy with follow-up imaging from the 4-m Telescopio…
A detailed star formation history for the extremely diffuse Andromeda XIX dwarf galaxy
Michelle L. M. Collins, Benjamin F. Williams, Erik J. Tollerud +3
We present deep imaging of the ultra-diffuse Andromeda XIX dwarf galaxy from the Advance Camera for Surveys on the Hubble Space Telescope which resolves its stellar populations to…
Observational constraints on stellar feedback in dwarf galaxies
Michelle L. M. Collins, Justin I. Read
Feedback to the interstellar medium (ISM) from ionising radiation, stellar winds and supernovae is central to regulating star formation in galaxies. Due to their low mass ($M_{*} <…
The nature of the Eastern Extent in the outer halo of M31
Janet Preston, Michelle Collins, R. Michael Rich +3
We present the first comprehensive spectroscopic study of the Andromeda galaxy's Eastern Extent. This ~4 degree long filamentary structure. located 70-90 kpc from the centre of M31…
Pisces VII: Discovery of a possible satellite of Messier 33 in the DESI Legacy Imaging Surveys
David Martinez-Delgado, Noushin Karim, Emily J. E. Charles +5
We report deep imaging observations with DOLoRes@TNG of an ultra-faint dwarf satellite candidate of the Triangulum galaxy (M33) found by visual inspection of the public imaging dat…
