A Haro galaxy is a blue galaxy similar to a Markarian galaxy, often elliptical or lenticular
in form, whose spectrum shows bright, sharp emission
lines. The emission may be from an active galactic
nucleus or from a recent burst of star
formation. These galaxies are named after Guillermo Haro,
who discovered them in 1956.
