3C 249.1 is a Seyfert galaxy located in the constellation Draco . It hosts a powerful radio source [ 3] and is located at redshift 0.3115, with a peculiar radio structure. One of its radio lobes is classified as having a Fanaroff-Riley classification Type II, while the other lobe has no features nor containing hotspots.[ 4]
3C 249.1 contains emission lines [ 5] with an extended emission-line region.[ 6] Its black hole is known to have a high accretion rate.[ 7]
The star formation rate in 3C 249.1 is estimated to be between ranges of ~1–250 M⊙ yr−1 , according to researchers using spectral energy distributions , as well as high resolution mid-infrared spectra of quasars from the Palomar–Green sample.[ 8]
