| we analyze the optical counterpart to the ultra - compact high velocity cloud agc 226067 , utilizing imaging taken with the advanced camera for surveys ( acs ) on the _ hubble space telescope_. the color magnitude diagram of the main body of agc 226067 reveals an exclusively young stellar population , with age @xmath0750 myr and [ fe / h]@xmath0@xmath10.3 , and is consistent with a distance of @xmath2@xmath317 mpc , suggesting an association with the virgo cluster . a secondary stellar system located @xmath01.6 ( @xmath08 kpc ) away in projection has a similar stellar population . the lack of an old red giant branch ( @xmath45 gyr ) is contrasted with a serendipitously discovered virgo dwarf in the acs field of view ( dw j122147 + 132853 ) , and the total diffuse light from agc 226067 is consistent with the luminosity function of the resolved @xmath0750 myr stellar population . the main body of agc 226067 has a @xmath5=@xmath111.3@xmath60.3 , or @xmath7=5.4@xmath61.3@xmath810@xmath9 @xmath10 given the stellar population . we searched 20 deg@xmath11 of imaging data adjacent to agc 226067 in the virgo cluster , and found two similar stellar systems dominated by a blue stellar population , far from any massive galaxy counterpart if this population has similar star formation properties as agc 226067 , it implies @xmath00.1 @xmath10 yr@xmath12 in virgo intracluster star formation . given its unusual stellar population , agc 226067 is likely a stripped remnant and is plausibly the result of compressed gas from the ram pressure stripped m86 subgroup ( @xmath0350 kpc away in projection ) as it falls into the virgo cluster . |
