NGC 3509 known as Arp 335, is a barred spiral galaxy[1] located in the constellation Leo.[2] [3] It is located 340 million light-years from the Solar System.[4] [5] NGC 3509 was discovered by astronomer William Herschel on December 30, 1786.[6]

Characteristics

NGC 3509 is a large galaxy. With a diameter of 215,000 light-years, it is much bigger than the Milky Way, which only has a diameter of at least 100,000 light-years. Its luminosity class is II-III and it has a broad HII region. Additionally, NGC 3509 is a peculiar galaxy showing an interesting detail.[7] It has a sweeping tidal tail feature, which seems to offer hints of evolution[8] and makes the galaxy resemble a tadpole.[9] A further study proves that this is not the case since NGC 3509 has a single undisturbed nucleus which is surrounded by dust lanes. This means it has not undergone a major disk-to-disk merger and instead had a minor merger with a smaller satellite galaxy. As the galaxy interaction between NGC 3509 and the galaxy occurs, certain starbursts are triggered [10] in regions along its spiral arms which causes it to actively create new stars.[11]

Another study proves that a galactic halo is growing in NGC 3509 through accretion of smaller galaxies, in which they leave a spur behind as they are tidally disrupted by their host galaxy.[12]

NGC 3509 is designated as Arp 335 in the Atlas of Peculiar Galaxies by Halton Arp,[13] in which it is placed into the Miscellaneous category, M82 being the well-known galaxy in this classification.[14]

Supernova

One supernova has been discovered in NGC 3509: SN 2010bi.

SN 2010bi

SN 2010bi[15] was discovered on March 24, 2010, by G. Piginata and M. Cifuentes along with other astronomers from University of North Carolina at Chapel Hill on the behalf of the CHASE project (CHilean Automatic Supernova sEarch).[16] SN 2010bi was found via an unfiltered image taken using the 0.41-m 'PROMPT 5' telescope located at Cerro Tololo. It was located 28".4 east and 34".6 north of the nucleus.[17] The supernova was Type IIP in which its progenitor might be a 8-16 solar mass red supergiant.
