RBS 1467 also known as J1508.6+2709, is a BL Lacertae object located in the constellation of Boötes. The redshift of the object is (z) 0.269[1] and it was first discovered from the ROSAT Bright Survey as a point-like source by astronomers in October 1998 where it is designated as 1RXS J150842.2+270910.[2]

Description

RBS 1467 is BL Lac object with a B-band apparent magnitude of 18.8 magnitude with its total radio flux density estimated to be 39.9 mJy at 1.4 GHz frequencies.[3] The V-band magnitude is estimated to be 18.50 magnitude while the flux density calculated by ROSAT band is 3.92 erg cm-2 s-1.[4]

It is also categorized as a high-energy-peaked BL Lac object (HBL) based on its synchrotron peaked frequency of 17.3.[5] A study published in 2012, has found it is a blazar detected by Fermi Gamma-ray Space Telescope with its gamma-ray photon flux measured to be 4.1 ± 1.1 × 10-10 photons cm-2 s-1 and has a gamma-ray photon spectral index of 1.97 ± 0.27 Γγ. The total X-ray flux density at 1 keV is found to be 1.01E-0.6 mJy.[6]

Evidence found RBS 1467 is a radio-loud gamma-ray active galaxy. It has a presence of a radio jet, with the jet power being estimated to be 45.2 erg s-1. The radius of the radio emission contained within a spherical region is found to be 16.8 centimeters while the magnetic field strength is -1.68 Gs.[7] A study published in 2022, has detected a parsec-scale jet with the jet position angle of -131° and has a median distance of 2.9 milliarcseconds between its jet components and its radio core.[8] A central supermassive black hole is found and estimated as 8.30 Mʘ. The accretion disk luminosity is 43.95 erg/s.[9]
