NGC 3735 is a spiral galaxy in the constellation of Draco. Its velocity with respect to the cosmic microwave background is 2,776±6 km/s, which corresponds to a Hubble distance of 133.5 ± 9.4 Mly (40.94 ± 2.87 Mpc).[1] Additionally, 19 non-redshift measurements give a closer mean distance of 123.87 ± 3.81 Mly (37.979 ± 1.167 Mpc).[2] It was discovered by German-British astronomer William Herschel on 7 December 1801.[3][4]
NGC 3735 is a Seyfert II galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.[5][6]
Supermassive black hole
[edit]Based on measurements of the near-infrared K-band luminosity of the galaxy's bulge, NGC 3735 has a supermassive black hole with a mass of 1×107.6M☉ (40 million solar masses).[7]
Nuclear maser source
[edit]A survey conducted in 1996 and 1997 for H2O maser emission in the active galactic nuclei of 29 galaxies found one new maser in NGC 3735.[8]
NGC 3735 group
[edit]NGC 3735 is a member the NGC 3735 group (also known as LGG 240), which contains three galaxies, including UGC 6552 [d] and UGC 6711 [d].[9][10]
Supernova
[edit]One supernova has been observed in NGC 3735:
