NGC 4203

NGC 4203 is a lenticular galaxy located approximately 30 million light-years away in the constellation Coma Berenices. It is a member of the Coma I Group, a small galaxy group associated with the larger Virgo Supercluster.

NGC 4203 is classified as type S0, indicating it possesses a prominent bulge and a flattened disk, but lacks well-defined spiral arms. The galaxy exhibits a smooth, featureless appearance in most optical images.

Observations of NGC 4203 have revealed a weak active galactic nucleus (AGN) at its center, suggesting the presence of a supermassive black hole that is accreting matter, albeit at a low rate. The AGN is classified as a LINER (Low-Ionization Nuclear Emission-line Region).

Studies of the stellar populations within NGC 4203 suggest a complex star formation history, with evidence of both old and relatively young stars. The presence of a dust lane crossing the galaxy's central region is also notable.

NGC 4203 has been the subject of various studies aimed at understanding the properties of lenticular galaxies, the nature of AGN activity in low-luminosity galaxies, and the distribution of dark matter in galaxy halos. Its relatively nearby location makes it a valuable target for detailed astronomical observations.
