NGC 4541

NGC 4541 is an intermediate spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 7,229±25 km/s, which corresponds to a Hubble distance of 347.8 ± 24.4 Mly (106.63 ± 7.47 Mpc).^[1] However, eight non-redshift measurements give a closer mean distance of 312.09 ± 9.57 Mly (95.688 ± 2.933 Mpc).^[2] It was discovered by German-British astronomer William Herschel on 1 January 1786.^[3]

Close

NGC 4541 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.^[4][5] NGC 4541 is also a radio galaxy, i.e. it has giant regions of radio emission extending well beyond its visible structure.^[6][5]
