NGC 3860 is aspiral galaxy[3] located about 340 millionlight-years away[4] in the constellationLeo.[5] NGC 3860 was discovered by astronomerWilliam Herschel on April 27, 1785.[6] The galaxy is a member of theLeo Cluster[7][8] and is a low-luminosityAGN (LLAGN).[9][10] Gavazzi et al. however classified NGC 3860 as a strongAGN which may have been triggered by asupermassive black hole in the center of the galaxy.[11]

H I deficiency

[edit]

Observations of NGC 3860 show that the galaxy has lost approximately 90% of its originalhydrogen content. This indicates that NGC 3860 has crossed though the core of the Leo Cluster and thatram pressure exerted by the denseintergalactic medium in the cluster stripped most of theneutral atomic hydrogen from the galaxy.[12]

The gas disk of NGC 3860 is truncated, which is an additional indicator that the galaxy is undergoing ram pressure stripping as it falls into the Leo Cluster.[13]
