WebNeutral hydrogen (H I) was first detected in galaxies in 1953 by Kerr and coworkers in the 21-cm (1420.40575 MHz) radio emission line. Since then it has been found that almost every spiral and irregular galaxy contains considerable neutral gas. In spiral galaxies, the H I emission distribution usually shows a central minimum and peaks in a ring ... WebAn irregular galaxy is a galaxy that does not have a distinct regular shape, like a spiral or an elliptical galaxy. The shape of an irregular galaxy is uncommon – they do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure. … can a man survive without a prostate
