NGC 4061 is an elliptical galaxy located 310 light-years away[2] in the constellation Coma Berenices.[3] It was discovered by astronomer William Herschel on April 27, 1785. It was rediscovered by John Herschel on April 29, 1832. It is listed both as NGC 4061 and NGC 4055.[4] NGC 4061 is a member of the NGC 4065 Group[5][6][7][8][9][10][11][12][13] and forms an interacting[14][15] pair with its companion, NGC 4065[8][14] as evidenced by distortions in their optical isophotes.[15][9]
NGC 4061 is classified as a radio galaxy[7][15][9][16][17][18][11][19] with a Fanaroff and Riley classification of type I.[20]
Radio Jets
[edit]NGC 4061 has two radio jets that appear to be very straight and that dramatically oppose each other. At a distance of 26,000 ly (8 kpc) from the core the jets appear to suddenly sweep back. This sudden bending of the jets suggest that they are leaving the interstellar medium (ISM) of NGC 4061 and entering into the intracluster medium (ICM). After the sharp bending, the jets continue to open for about 82,000 ly (25 kpc) and extend into a "U" or horseshoe morphology similar to NGC 1265, with each jet having a length of 160,000 ly (50 kpc). This morphology is thought to be due to the motion of NGC 4061 through the ICM with sufficient velocity to bend the jets by ram-pressure stripping.[15]
The interaction with NGC 4065 may have also contributed to bending the jets.[9]
Dust Disk
[edit]Supermassive black hole
[edit]NGC 4061 has a supermassive black hole with a mass in the range of 1-9 billion M☉.[22][23]
SN 2008bf
[edit]On February 18, 2008 a type Ia supernova designated as SN 2008bf was discovered in NGC 4061.[24][25][26][27] However, the Open Supernova Catalog suggests that the host galaxy may be the nearby NGC 4065.[27]

[edit]Notes
[edit]- 1.^ This was determined by multiplying the given scale length in the paper of 0.55 arcseconds=820 ly (250 pc) by 9.1 to get the diameter of the dust disk.
