Gemini/GMOS Spectra of Globular Clusters in the Leo Group Elliptical NGC 3379
Michael Pierce, Michael A. Beasley, Duncan A. Forbes +8
We have obtained Gemini/GMOS spectra for 22 GCs associated with NGC 3379. We derive ages, metallicities and alpha-element abundance ratios from simple stellar population models usi…
The 2dF Galaxy Redshift Survey: correlation with the ROSAT-ESO Flux Limited X-ray (REFLEX) galaxy cluster survey
Matt Hilton, Chris Collins, Roberto De Propris +25
The ROSAT-ESO Flux Limited X-ray (REFLEX) galaxy cluster survey and the 2dF Galaxy Redshift Survey (2dFGRS) respectively comprise the largest, homogeneous X-ray selected cluster ca…
New Light on the Formation and Evolution of M31 and its Globular Cluster System
Thomas H. Puzia, Kathy M. Perrett, Terry J. Bridges
We present spectroscopic ages, metallicities, and [alpha/Fe] ratios for 70 globular clusters in M31 that were derived from Lick line-index measurements. In addition to a population…
The 2dF Galaxy Redshift Survey: Power-spectrum analysis of the final dataset and cosmological implications
S. Cole, W. J. Percival, J. A. Peacock +28
We present a power spectrum analysis of the final 2dF Galaxy Redshift Survey, employing a direct Fourier method. The sample used comprises 221,414 galaxies with measured redshifts.…
