VCC 479 shows symmetric stellar shells, a strongly HI-deficient and centrally concentrated gas distribution, and a roughly 600 Myr-old central starburst embedded in a disk that quenched about 900 Myr ago, consistent with a gas-poor major merger of dwarfs in the Virgo outskirts.

AVID: Formation and evolution of a coalesced major merger of late-type dwarf galaxies (VCC 479) on the outskirts of the Virgo cluster
VCC 479 shows symmetric stellar shells, a strongly HI-deficient and centrally concentrated gas distribution, and a roughly 600 Myr-old central starburst embedded in a disk that quenched about 900 Myr ago, consistent with a gas-poor major merger of dwarfs in the Virgo outskirts.
