NGC 2935

NGC 2935 is a large intermediate spiral galaxy located in the constellation Hydra. Its speed relative to the cosmic microwave background is 2,601 ± 23 km/s, which corresponds to a Hubble distance of 38.4 ± 2.7 Mpc. It was discovered by German-British astronomer William Herschel on 20 March 1786.
NGC 2935 was used by Gérard de Vaucouleurs as a galaxy of morphological type SABb in his galaxy atlas. The luminosity class of NGC 2935 is II and it has a broad HI line. In addition, it is a star-forming burst galaxy.
To date, 29 studies and measurements based on redshift give a distance of 27.890 ± 3.962 Mpc, which is outside the Hubble distance values. Note that it is with the average value of independent measurements, when they exist, that the NASA/IPAC database calculates the diameter of a galaxy and that consequently the diameter of NGC 2935 could be approximately 78, 1 kpc if we used the Hubble distance to calculate it.

Nuclei disk

Observations from the Hubble Space Telescope have concluded that a star-forming disk is present around the core of NGC 2935. The size of its semi-major axis is estimated at 530 pc at the estimated distance of this galaxy.

Four supernovae have been discovered in NGC 2935:SN 1975F was discovered by Yvonne Dunlap and Justus R. Dunlap of the Corralitos Observatory at Northwestern University on 11 June 1975.SN 1996Z was discovered by Wayne Johnson on 16 May 1996.SN 2021mwj was discovered by ATLAS on 21 May 2021.SN 2021aczp was discovered by ATLAS on 1 November 2021.

NGC 2935 is part of a small group of three galaxies named after it. The other two galaxies in the NGC 2935 group are NGC 2983 and NGC 2986.
