J1000+1242 known as SDSS J1000+1242 or J1000+12 is a radio-quiet type-2 quasar,[1] located in the constellation Leo. It is located 2 billion light years from Earth and is classified as a Seyfert galaxy.[2]

Characteristics

J1000+1242 has disturbed morphology indicating a galaxy merger. A tidal tail is clearly seen elongating away from the host galaxy towards south by 72 kiloparsecs (kpc), terminating at a location of a small source which implies a tidal dwarf galaxy.[3]

Two unique nuclear emission sources are located in the galaxy. They have a projected separation of around 1.5 kpc indicating the merger resulted J1000+1242 having two active galactic nuclei (AGN) or from both sides of its narrow-line region concealed by a torus of gas and warm dust, or a circumnuclear ring.[4] A bright emission line region is also found northeast of the nucleus of J1000+1242, with an irregular morphology indicating an outflowing bi-polar superbubble.[5]

J1000+1242 has features of a typical AGN. This includes a radio core and hotspot.[6] There is a presence of a deflected radio jet producing diffused lobes in both southeast and northwest directions.[7] Not to mention, J1000+1242 has broad line regions producing emission lines with widths reaching to w80 of 850 km s-1.[8] In both around and inside its radio lobes measuring ~ 10 kpc, J1000+1242 has five filamentary molecular gas structures. They seem to wrap around the radio lobes, which ~ 9 percent of the total molecular gas mass is found enclosed within these structures.

Star formation

J1000+1242 has an estimated star formation rate of 50 ± 10 Mʘ yr-1 with infrared luminosity deriving from its star formation in an 8-1000 ɥm range, of 45.0+0.1-0.2 erg s-1.[9]

Black hole

The black hole in J1000+1242 is estimated to be 8.47 ± 0.76 Mʘ based on MBH-σ* relation.[10]
