Metallicity Gradients at Large Galactocentric Radii Using the Near-infrared Calcium Triplet
Caroline Foster, Robert N. Proctor, Duncan A. Forbes +3
We describe a new spectroscopic technique for measuring radial metallicity gradients out to large galactocentric radii. We use the DEIMOS multi-object spectrograph on the Keck tele…
Probing the 2-D kinematic structure of early-type galaxies out to 3 effective radii
Robert N. Proctor, Duncan A. Forbes, Aaron J. Romanowsky +5
We detail an innovative new technique for measuring the 2-D velocity moments (rotation velocity, velocity dispersion and Gauss-Hermite coefficients h and h) of the stellar…
The mass-metallicity gradient relation of early-type galaxies
Max Spolaor, Robert N. Proctor, Duncan A. Forbes +1
We present a newly observed relation between galaxy mass and radial metallicity gradients of early-type galaxies. Our sample of 51 early-type galaxies encompasses a comprehensive m…
