BZQ J1727+5510 also known as OGC 1369 and GB6 J172722+551059, is a BL Lacertae object located in the constellation of Draco. The redshift of the object is (z) 0.247[1] and it was first discovered in the Cosmic Lens All-Sky Survey (CLASS) in October 2001, by astronomers who classified it as a radio source with a flat radio spectrum.[2] It is the brightest cluster galaxy of the galaxy cluster Abell 2270.[3][4]

Description

[edit]

BZQ J1727+5510 is an elliptical galaxy with an estimated R-band luminosity of 8.2 magnitude based on an R-band luminosity measurement made by the Sloan Digital Sky Survey (SDSS).[5] It is categorized as a Type 2 active galactic nucleus (AGN) displaying emission lines of singly ionized oxygen, doubly ionized oxygen as well as both h-gamma and h-beta in its optical spectrum.[6] The total star formation rate of the galaxy is estimated to be 93.5+69.4−57.3 M☉ per year, with the galaxy having an estimated age of 7.49+1.77−1.81 billion years. The total infrared luminosity of the galaxy is 11.97+0.24−0.41 L☉.[7] The galaxy's stellar mass has been calculated to be 11.73 ± 0.11 M☉ while the central supermassive black hole has a mass of 7.12 M☉.[8] The g –r color offset of the galaxy is -0.39 magnitude.[9]

A study in published in 2026 has reclassified BZQ J1727+5510 as a Type 1 AGN from a Type 2 AGN. It has a radio luminosity of 41.68 erg s−1 that is obtained from the Faint Images of the Radio Sky at Twenty-Centimeters (FIRST) survey conducted at 1.4 GHz frequencies. The galaxy also displays detected doubly ionized oxygen (O III) outflows with the O III emission lines displaying an outflow strength of 510.30 kilometers per second.[8]

Radio imaging made by the Very Long Baseline Interferometry (VLBI) found BQZ J1727+5510 has a parsec-scale jet that is orientated at a position angle of -18° with the median distance of the jet and core components estimated to be 3.6 milliarcseconds based on a standard average deviation.[10] The mean flux density of the galaxy is 236 mJy, with detected variability of 4.1%.[11]
