IC 4588

IC 4588 is a type E^[1] elliptical galaxy located in the constellation Serpens.^[2][3] It is located 729 million light-years from the Solar System^[4] and has a dimension of 0.30 x 0.3 arcmin meaning its diameter is 64,000 light-years across.^[5] IC 4588 was discovered by Stephane Javelle on July 15, 1903.^[6]

In some galactic catalogues, NGC 6051 and IC 4588 have been listed as the same object.^[7] However, O'Sullivan and associates (2011) have them as separate entities, with NGC 6051 being the central dominant galaxy of a cluster.^[8]

Supernova

One supernova has been discovered in IC 4588 so far: SN 2023ifv.

SN 2023ifv

SN 2023ifv was discovered on May 13, 2023^[9] by ATLAS (Asteroid Terrestrial-impact Last Alert System) which was developed by the University of Hawaii.^[10] It was reported by multiple astronomers from University of Hawaii, South African Astronomical Observatory, ESO, UAI Obstech, Oxford/QUB, Queen's University Belfast, Oxford and Harvard; via a cyan-ATLAS filter which was taken using ATLAS Haleakala telescope.^[11] The supernova reached a magnitude of 18.^[12]

On May 19, 2023, C. Fremling, D. Neill, and Y. Sharma on the behalf of the SDEM Team from Caltech and the Zwicky Transient Facility, confirmed SN 2023ifv to be a Type Ia supernova.^[13][14] The supernova probably resulted from the destruction of a white dwarf in a binary system.^[15][16]
