Multi-frequency properties of an interacting narrow-angle tail radio galaxy J0037+18

Abstract

We report multi-wavelength and multi-band observations of a radio galaxy, J0037+18, optical counterpart of which appears to be interacting with the galaxy J003754+182118. We present the map of J0037+18 in various radio frequencies and discuss radio properties of the source using data from the Giant Meterwave Radio Telescope and the Very Large Array. We use optical data to investigate the environment of the host. The angle between the upper lobe and the lower lobe of the radio galaxy is found to be 38 degree near the base of the jets which makes it a narrow-angle tail galaxy. Spectral index based on radio observations between 148 MHz and 1489 MHz exhibit a strong gradient along the jet with flatter spectra near the core and steeper spectra near the outer ends.
