NGC 4298 is aflocculent[3][4][5][6]spiral galaxy located about 53 millionlight-years away[7] in the constellationComa Berenices. The galaxy was discovered by astronomerWilliam Herschel on April 8, 1784[8] and is a member of theVirgo Cluster.[9][10][11]

NGC 4298 may harbor anintermediate-mass black hole with an estimated mass ranging from 20,000 (2×104M☉) to 500,000 (5×105M☉)solar masses.[12]

Interaction with NGC 4302

[edit]

NGC 4298 appears to form a pair with[13][14][15] and appears tointeract withNGC 4302.[13][2][14][16][15][17][18][4] Evidence for an interaction between the two galaxies are that NGC 4298 exhibits a lopsided, asymmetrical distribution of stars,[4][16][15] a tidal bridge that connects it toNGC 4302,[18][17][2] a prodigious rate ofstar formation[19] and an HI-tail. However, the tail is also the result ofram pressure.[3]

The two galaxies are separated from a projected distance of ~36,000 ly (11 kpc).[20][15][3]

Ram-pressure stripping

[edit]

The presence of a truncated gas disc,[3][4] an asymmetric 6 cm polarized radio continuum distribution,[13] an HI-tail,[3] and asymmetries of gas in a similar direction as theram pressure stripped gas inNGC 4302 suggest that NGC 4298 is undergoingram pressure.[2]
