NGC 4571 is a spiral galaxy located in the constellation of Coma Berenices that William Herschel thought it could be the object #91 in Charles Messier' catalog of deep-sky objects, before nearly two centuries later that object was determined to be the nearby [2 ] barred spiral galaxy NGC 4548.
Physical properties [ edit ]
The finding of
Cepheids by the Canada France Hawaii Telescope in 1994 has allowed to know this galaxy is a member of the Virgo Cluster. [2 ]
Despite being classified as a
late-type galaxy, NGC 4571 has features more typical of spiral galaxies of earlier Hubble type such as a high color index, both low star formation rate and H-Alpha brightness, and relatively little neutral hydrogen, suggesting it may have lost most of its gas due to interactions with Virgo's [3 ] intragalactic medium and/or past interactions with other galaxies of the cluster. [4 ] [5 ] [5 ] [6 ]
low-surface brightness galaxy Malin 1 is located close to this object. It's totally unrelated, however as it lies at a much higher distance. [7 ]
