NGC 4294 is a barred spiral galaxy [2] with flocculent spiral arms [3] located about 55 million light-years away [2] in the constellation Virgo. The galaxy was discovered by astronomer William Herschel on March 15, 1784 [4] and is a member of the Virgo Cluster. [5] [6] [7]

Contents

NGC 4294 appears to be undergoing ram-pressure [8] [9] stripping edge-on. [8]

Physical characteristics

NGC 4294 hosts many H II regions. [10] [3]

Interaction with NGC 4299

NGC 4294 appears to be in a pair with NGC 4299 [11] [12] [10] [13] [9] [14] [15] and may be possibly tidally interacting. [11] [12] [10] [13] [3] [9] [14] [15]

Effects of a tidal interaction on NGC 4294 are evident as the galaxy has a disturbed optical and HI morphology, [12] [10] a high global star formation rate, [13] [3] and has an observed asymmetry in polarized radio continuum emission. [15]

HI tail

Chung et al. identified that NGC 4294 has a one sided [16] [17] 88,000  ly (27  kpc ) tail of neutral atomic hydrogen (HI). [9] [18] The tail points to the southwest [16] [14] and appears to be a result of ram-pressure. [18] [19] [9] The tail has no optical counterpart [9] [16] and is oriented parallel to the HI tail found in NGC 4299. [16]

As the tail has no optical counterpart, this makes the probability of the tail being caused by tidal interaction low. However, NGC 4299 lies 88,000  ly (27  kpc ) from NGC 4294 and the two galaxies have almost the same velocity, with a difference of 120 km/s. This means that the scenario of the tail originating from a tidal interaction cannot be ruled out entirely. [9]

Black Hole

NGC 4294 may harbor an intermediate-mass black hole with an estimated mass ranging from 3,000 (3*10^3) to 20,000 (2*10^4) solar masses. [20]
