redshift evolution of dust extinction (Naveen Reddy (Hubble Fellow, NOAO))


Using the luminosity ratio to illustrate the extinction, galaxies in redshift 2 are brighter than local galaxies with the same extinction. That's why there is extinction correction when plot the SFR vs redshift.


galaxies in redshift 2 are brighter than the local galaxies with the same extinction or metallicity.
