  The spiral is NGC 7518 (and a whole lot of other names too); it's a member of the Pegasus cluster.

  The radio emission coincides with the nucleus; this is common in galaxies. It may indicate that there's an AGN, or a nuclear starburst, or both; a good (optical) spectrum can usually distinguish these possibilities.

  Hope this helps and happy hunting! 😃
