The Evolution Of Carbon, Sulphur, and Titanium Isotopes from High-Redshift to the Local Universe
G. L. Hughes, B. K. Gibson, L. Carigi +3
Recent observations of carbon, sulphur, and titanium isotopes at redshifts z~1 and in the local stellar disc and halo have opened a new window into the study of isotopic abundance…
Chemodynamical Simulations of Elliptical Galaxies
Brad K. Gibson, Patricia Sanchez-Blazquez, Stephanie Courty +1
We review recent developments in the field of chemodynamical simulations of elliptical galaxies, highlighting (in an admittedly biased fashion) the work conducted with our cosmolog…
Stellar populations of early-type galaxies in different environments III. Line-strength gradients
P. Sanchez-Blazquez, J. Gorgas, N. Cardiel
We present line-strength gradients for 22 spectral indices measured in a sample of 82 early-type galaxies in different environments,including the high-density core of the Coma clus…
An Imaging Study of the Globular Cluster Systems of NGC 1407 and NGC 1400
Duncan Forbes, Patricia Sanchez-Blazquez, Anna Phan +3
We present wide-field Keck telescope imaging of the globular cluster (GC) systems around NGC 1407 and NGC 1400 in the Eridanus galaxy cloud. This is complemented by Hubble Space Te…
On the Environmental Dependence of Cluster Galaxy Assembly Timescale
C. Carretero, A. Vazdekis, J. E. Beckman +2
We present estimates of CN and Mg overabundances with respect to Fe for early-type galaxies in 8 clusters over a range of richness and morphology. Spectra were taken from the Sloan…
Rings in the Haloes of Planetary Nebulae
R. L. M. Corradi, P. Sanchez-Blazquez, G. Mellema +2
We present a search for rings or arcs in the haloes of planetary nebulae (PNe). We discovered such structures in eight PNe, tripling the sample of PNe with known rings. This shows…
