Blueberry Galaxy
Blueberry galaxies (BBs) are Dwarf galaxy, dwarf Starburst galaxy, starburst galaxies that have very high ionization rates and some of the lowest stellar masses and Metallicity, metallicities. They are smaller counterparts of Pea galaxy, Green Pea galaxies (GPs), but * are more compact being less than th the size of the Milky Way, * are less distant, existing in low-density environments that are within the local universe, and * have lower luminosity, luminosities. BBs form one of the youngest classes of star-forming galaxies with median ages ~70 Myr. Two BBs are among the most metal-poor galaxies known within the local universe. BBs were first named in the scientific literature by Yang et al. (2017) as GPs that were at a distance of redshift z=0.05 or less, although similar galaxies had originally been named BBs on the Galaxy Zoo website. While Yang et al. identified a sample of 40 BBs, a much larger sample was acquired using data from the LAMOST DR9 survey. Liu et al ...
