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]

Discovery

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]

Characteristics

The host galaxy of III Zw 2 was initially classified as a spiral galaxy.[6] However according to a recent study made on its budge and disk decomposition via Hubble Space Telescope in 2009, it has since been reclassified as an elliptical galaxy.[7] It has a star-forming tidal bridge feature indicating a merger with a companion galaxy.[8] Furthermore, III Zw 2 belongs to a class of radio-intermediate quasars and is a member of a triple galaxy system.[9]

Active nucleus

The nucleus of III Zw 2 is active. In additional, to its superluminal jet, the galaxy shows two distinctive γ-ray flares happening between November 2009 and May 2010, according to observations by Fermi-LAT. It is also known to have a highly variable radio core flux density between factor of 20-30.[10]

Black hole

III Zw 2 contains a supermassive black hole[11] of 7.4 × 108 M⊙.[12] The black hole is responsible for producing an ionized wind outflow with a velocity of (−1780 ± 670) km s−1.[13] Approximately every five years the galaxy emits dramatic radio outbursts.[14]
