Abstract (from CDS):

We present the first stellar stream discovered with the Vera C. Rubin Observatory, around spiral galaxy M61 (NGC 4303) in Virgo First Look imaging. The stream is narrow, radially-oriented in projection, and ∼ 50 kpc long. It has g-band surface brightness μg ∼ 28 AB mag arcsec–2, color g - z ∼ 1.0, and stellar mass M⋆ ∼ 2 × 108M⊙. This dwarf galaxy interaction may have provoked the M61 starburst, and foreshadows the bounty of accretion features expected in the ten-year Rubin Legacy Survey of Space and Time.
