Glossary

Age

age of the stellar population in Myr

Emission line fluxes

corrected for the Galactic dust extinction, expressed in units of 10-17ergs s-1 cm-2. Host dust extinction and stellar Balmer absorption corrections are not applied

Galactic dust extinction

extinction due to dust in the Milky Way along the GRB line of sight , expressed as a color excess EB-V

GRB

gamma-ray burst name

Luminosity distance

for the cosmology with H0= 70 km s-1 Ωm = 0.3 & ΩΛ = 0.7

log(M/M)

stellar mass in solar units, as measured from the optical-NIR photometry

Redshift

redshift of the host galaxy or GRB afterglow

SED

spectral energy distribution of the host galaxy, corrected for the Galactic dust extinction

AV

Optical extinction in the host galaxy, as measured from Balmer decrement

log(Z/Z)

Log of metal content in solar units, as measured from emission lines or absorption lines

SFR

Star formation rate in the host galaxy, in units of M yr-1, as measured from optical emission lines or UV emission

SSFR

Specific star formation rate in the host galaxy (SFR divided by total stellar mass), in units of Gyr-1

T90

Duration of γ-ray emission of GRB, the time interval over which 90% of the total counts are observed
