Low- and high-redshift H II starburst galaxies obey different luminosity-velocity dispersion relations

Shulei Cao, Bharat Ratra

To determine whether or not H II starburst galaxies (H IIG) are standardizable candles, we study the correlation between the H $β$ luminosity ( $L$ ) and the velocity dispersion ( $σ$ )…
