Abstract:It is exceedingly rare to find quiescent low-mass galaxies in the field at low redshift. UGC 5205 is an example of such a quenched field dwarf (M
⋆ ∼ 3 × 108
M
⊙). Despite a wealth of cold gas (M
HI ∼ 3.5 × 108
M
⊙) and UV emission that indicates significant star formation in the past few hundred megayears, there is no detection of Hα emission—star formation in the last ∼10 Myr—across the face of the g… Show more
