III Zw 2 is a Seyfert 1 galaxy located in the Pisces constellation. It has a redshift of 0.089 and is notable as the first of its kind to exhibit a superluminal jet.[1][2]
III Zw 2 was first discovered by Fritz Zwicky via a 48-inch Schmidt survey as a stellar object with faint wisps.[3] However, it was confirmed to have a Seyfert morphology with classical broadline characteristic based on further spectroscopic studies.[4] It was also included in Palomar Green quasar sample.[5]
