The MUSE-Faint survey. IV. Dissecting Leo T, a gas-rich relic with recent star formation

Understand

Leo T ($M_V = -8.0$) is both the faintest and the least massive galaxy known to contain neutral gas and to display signs of recent star formation.

• We analyse photometry and stellar spectra to identify member stars and to better understand the overall dynamics and stellar content of the galaxy and to compare the properties of its young and old stars.
• We use data from the Multi Unit Spectroscopic Explorer (MUSE) on the VLT.
• We supplement this information with spectroscopic data from the literature and with Hubble Space Telescope (HST) photometry.
