A Star-forming Galaxy in the Localization Region of FRB 110214
Abstract
FRB 110214 is among the smallest dispersion measure fast radio bursts (FRBs) that allow investigation of possible host galaxies thanks to its nearby nature z < 0.14. Here we present the discovery of a star-forming galaxy, WISE J012010.70-495041.5, in the 1σ localization region of FRB 110214. This star-forming galaxy can be seen from the optical and near-infrared archival data presented in Petroff et al. Based on optical, near-infrared, and mid-infrared imaging, WISE J0120-4950 is similar to the host of the repeating FRB 121102 both in morphology and spectral energy distribution (SED). From multiwavelength photometry, we compare its SED to the host of FRB 121102, and found a redshift of z ∼ 0.1, within the range of z < 0.14 constrained by the dispersion measure.
