We present deep spectroscopy of 17 very low mass (M* similar or equal to 2.0 x 10(6)-1.4 x 10(9) M-circle dot) and low luminosity (M-UV similar or equal to -13.7 to -19.9) gravitationally lensed ga ...

• THE EVOLUTION OF THE GALAXY REST-FRAME ULTRAVIOLET LUMINOSITY FUNCTION OVER THE FIRST TWO BILLION YEARS (2014, background): “The constraints from Lyα emission are heavily model dependent, and studies claiming a very low value of xH II may be assuming a velocity offset of Lyα from systemic that is too high (e.g., Stark et al. 2014).”

Thirteen billion years of stellar mass assembly in ten snapshots (2017, methodology): “Instead of using an exponentially increasing SFH (Maraston et al. 2010) we opt for a multi-component parametrisation (Stark et al. 2014): a constant SFH is superimposed to a delayed τ model with SFR ∝ τ−2te−t/τ (see Simha et al. 2014) where the e-folding time τ is equal to 0.5 Gyr and t = 10−40 Myr…”
