PublicaciónThe S2N2 metallicity calibrator and the abundance gradient of M33
We introduce the log(Hα/[SII]λλ6717+6731) versus log(Hα/[NII]λ6583) (S2N2) diagnostic diagram as a metallicity and ionization parameter indicator for HII...

PublicaciónThe S4G Perspective on Circumstellar Dust Extinction of Asymptotic Giant Branch Stars in M100
We examine the effect of circumstellar dust extinction on the near-IR (NIR) contribution of asymptotic giant branch (AGB) stars in intermediate-age clusters...

PublicaciónThe Sagittarius dwarf irregular galaxy (SagDIG): distance and star formation history
The distance, star formation history and global properties of the Local Group dIrr galaxy SagDIG are derived based on an [I-(V-I)] colour-magnitude diagram of ~...

PublicaciónThe SAMI galaxy survey: stellar population radial gradients in early-type galaxies
We study the internal radial gradients of the stellar populations in a sample comprising 522 early-type galaxies (ETGs) from the SAMI (Sydney-AAO Multi-object...
