Quasar in the constellation of Coma Berenices
3C 275.1 is aquasar located in theconstellation ofComa Berenices with aredshift of (z) 0.555.[ 1] It was first discovered in 1986 byastronomers , and is situated in the center of a richgalaxy cluster .[ 2] Its host is classified as a giantelliptical galaxy , described as either a proto-cD orType-cD galaxy with an emissionnebula surrounding it.[ 3] [ 4] [ 5]
3C 275.1 is classified as agamma-ray lobe-dominated quasar.[ 6] It has a radio structure consisting of an elongated core with a narrowjet heading in northwards direction based on a super-resolved radio imaging made by theVery Long Baseline Array (VLBA).[ 7] Radio mapping at 15GHz with a 5-kilometertelescope shows 3C 275.1 to contain a double component showing one side as compact and the other being slightly extended.[ 8] A study also described the southern component of the quasar as distorted, indicating the quasar is stronglyinteracting with a companion galaxy.[ 9] [ 10]
Observations made in 1986 revealed the presence of a rotatinggas cloud around 3C 275.1 with adiameter of more than 100kiloparsecs (Kpc). Based on observations, it was found to be the largest known to surround a quasar and is likely remnants created bytidal interactions or material that is accumulated viacooling flows originating from the cluster.[ 11] A more detailed study published in 2024, showed the cloud to be a nebula, containingionized gas tails that extends up to 170 kiloparsecs, typical ofJellyfish galaxies .[ 12] The nebula is described as having aconical shape with a bar-shaped extension that is located southwards from the nucleus[ 13] with an extended component having anX-ray emission of 7.6 x 1043 erg s−1 .[ 14]
In the center of 3C 275.1, there is asupermassive black hole estimated to have a mass of about 200 millionsolar masses based on a black hole-spheroid mass ratio calculated foractive galactic nuclei .[ 15] [ 12] The quasar itself is paired with the nearby galaxyNGC 4651 , due to the radio emitter alignment at the rear of the latter's outergalactic disk .[ 16]
