UGC 5101

April 10, 2024

UGC 5101 is a galaxy merger located in the constellation Ursa Major. It is located at a distance of about 530 million light years from Earth. It is an ultraluminous infrared galaxy.[1] The total infrared luminosity of the galaxy is estimated to be 1011.95 L☉ and the galaxy has a total star formation rate of 105 M☉ per year.[2]

UGC 5101 has a single nucleus surrounded by spiral isophotes.[3] The nucleus of UGC 5101 has been found to be active and it has been categorised as a type 1.5 Seyfert galaxy or a LINER based on the radio continuum.[4][5] The most accepted theory for the energy source of active galactic nuclei is the presence of an accretion disk around a supermassive black hole. The mass of the black hole in the centre of UGC 5101 is estimated to be 108.2 (160 million) M☉ based on stellar velocity dispersion.[6] The galaxy also hosts a water megamaser, probably originating from the nucleus.[7]

The nucleus emits hard X-rays, which are strongly absorbed, while there is also a soft X-rays component, which could originate from a hidden starburst region.[8] Also NeV emission has been detected in the nucleus, indicating the presence of a hot gas in the coronal line region, while hot dust has been detected around the nucleus, as indicated by the presence of PAH emission and strong silicate absorption.[9][10][11] The nucleus is surrounded by a dust torus with an opening angle larger than 41° which partly obstructs the nucleus with a column density of NHLS about 1.3×1024 cm−2. The hole of the torus is covered with compton thin material.[12] The integrated intensities of HCN to 13CO indicate the gas in the torus is very dense.[13] When observed with very-long-baseline interferometry the galaxy features a ridgeline that could be compact jets generated by the active nucleus.[14]

The galaxy has a tidal tail, seen edge on, and a faint halo of stars that was created during the merger.[15] A second tidal tail appears to loop around the nucleus, forming a ring.[3]
