We conduct a detailed comparison between the kinematics, morpology and excitation conditions of the RW Aur microjet on scales 200 AU with predictions from...
The S2 stream: the shreds of a primitive dwarf galaxy
The S2 stream is a kinematically cold stream that is plunging downwards through the Galactic disc. It may be part of a hotter and more diffuse structure called...

The 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...
The 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...
The 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 ~...
The SAMI Galaxy Survey: Stellar Population Gradients of Central Galaxies
We examine the stellar population radial gradients (age, metallicity, and [α/Fe]) of 96 passive central galaxies up to ∼2 R e in the SAMI Galaxy Survey. The...
The 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...
The SAMI Galaxy Survey: the third and final data release
We have entered a new era where integral-field spectroscopic surveys of galaxies are sufficiently large to adequately sample large-scale structure over a...
