NGC 4299 is a featureless spiral galaxy[2] located about 55 million light-years away[3][4] in the constellation Virgo. It was discovered by astronomer William Herschel on March 15, 1784[5] and is a member of the Virgo Cluster.[6][4][7]

NGC 4299 forms an interacting pair with NGC 4294.[8]

Physical characteristics

NGC 4299 has a fairly featureless disk[9] with a very small, weak bulge and weak, asymmetric spiral arms[10] plus numerous bright HII regions.[11][12]

At the center of NGC 4299 lies a nuclear star cluster[13][14] with a diameter of ~5.9 ly (1.8 pc).[15]

Truncated Hα disk

NGC 4299 has a truncated Hα disk with the outer extent of the Hα having an irregular distribution except in the southwest where it forms a well-defined ridge. This appears to be the result of ram-pressure.[12]

Interaction with NGC 4294

As a result of a tidal interaction with NGC 4294, NGC 4299 has a disturbed optical and HI morphology,[16][11] with asymmetric spiral arms, a small, weak bar[10] and a high global star formation rate that appears to have been enhanced by ram-pressure.[12]

HI tail

Chung et al. identified that NGC 4299 has a one sided[17][18] tail of neutral atomic hydrogen (HI).[10][19] The tail points to the southwest[17][8] and appears to be a result of ram-pressure[19][20][10] or by a tidal interaction with NGC 4294.[10] The tail has no optical counterpart[10][17] and is oriented parallel to the HI tail found in NGC 4294.[17]

NGC 4299 appears to have a second tail pointing to the southeast that is much broader and lower in HI surface density than the main tail.[17]

Black Hole

NGC 4299 may harbor an intermediate-mass black hole with an estimated mass ranging from 7,000 (7*10^3) to 200,000 (2*10^5) solar masses.[21]
