Astronomers probed the origin of optical variability of low-redshift emission-line galaxies

Recently, astronomers from the Shanghai Astronomical Observatory of the Chinese Academy of Sciences used a sample of emission line galaxies in the COSMOS field with two-epoch narrowband imaging separated by 12 years to study their optical variability. Only a small fraction of galaxies was found showing opt...

Astronomers find that denser and more turbulent environments tend to form multiple stars

Astronomers studying stellar nurseries, the birthplace of stars in our galaxy, have found that nearly half of stars in the Galaxy are formed in binary/multiple stellar systems (think twins, triplets, quadruplets)[1]. Despite the prevalence of binary/multiple births previous studies of stellar nurseries hav...
