Luminosity and stellar mass functions of discs and spheroids in the SDSS and the supermassive black hole mass function (2007)

Benson, A. J., Džanović, Dajana, Frenk, C. S., Sharples , Ray

Using the galactica (GALaxy Automated ComponenT Image Construction Algorithm) code of Benson et al., we obtain quantitative measurements of spheroid-to-disc ratios for a sample of 8839 galaxies...

Luminosity and stellar mass functions of disks and spheroids in the SDSS and the supermassive black hole mass function (2006)

Benson, A. J., Dzanovic, Dajana, Frenk, C. S., Sharples, Ray

Using the Galactica code of Benson et al., we obtain quantitative measurements of spheroid-to-disk ratios for a sample of 8839 galaxies observed in the Sloan Digital Sky Survey. We carry out...

Gemini/GMOS Spectra of Globular Clusters in the Virgo Giant Elliptical NGC 4649 (2006)

Pierce, Michael, Bridges, Terry, Forbes, Duncan A., Proctor, Robert, Beasley, Michael A., Gebhardt, Karl, ...

NGC 4649 (M60) is one of a handful of giant Virgo ellipticals. We have obtained Gemini/GMOS spectra for 38 GCs associated with this galaxy. Applying the multi-index chi^2 minimisation technique of...

The globular cluster kinematics and galaxy dark matter content of NGC 4649 (M60) (2006)

Bridges, Terry, Gebhardt, Karl, Sharples, Ray, Faifer, Favio R., Forte, Juan C., Beasley, Michael A., ...

From observations with the GMOS multislit spectrograph on the Gemini North telescope, we have obtained spectra for 39 globular cluster (GC) candidates in the Virgo giant elliptical galaxy NGC 4649...

Gemini/GMOS Spectra of Globular Clusters in the Leo Group Elliptical NGC 3379 (2005)

Pierce, Michael, Beasley, Michael A., Forbes, Duncan A., Bridges, Terry, Gebhardt, Karl, Faifer, Favio Raul, ...

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 using the multi-index...

Gemini/GMOS Imaging of Globular Clusters in the Virgo Galaxy NGC 4649 (M60) (2004)

Forbes, Duncan A., Faifer, Favio Raul, Forte, Juan Carlos, Bridges, Terry, Beasley, Michael A., Gebhardt, Karl, ...

We present Sloan g and i imaging from the GMOS instrument on the Gemini North telescope for the globular cluster (GC) system around the Virgo galaxy NGC 4649 (M60). Our three pointings, taken in good...

Globular Clusters in Early-Type Galaxies with GMOS (2003)

Bridges, Terry, Beasley, Mike, Faifer, Favio, Forbes, Duncan, Forte, Juan, Gebhardt, Karl, ...

We present recent results from our long-term Gemini/GMOS study of globular clusters in early-type galaxies. To date, we have obtained photometry and spectroscopy for clusters in NGCs 3379, 4649, 524,...

Multiple Integral Field Spectroscopy (2002)

Wright, Gillian, Ivison, Rob, Hastings, Peter, Wells, Martyn, Sharples, Ray, Allington-Smith, Jeremy, ...

Integral-field spectroscopy is the most effective method of exploiting the superb image quality of the ESO-VLT, allowing complex astrophysical processes to be probed on the angular scales currently...

A Million Element Integral Field Unit (MEIFU) (2001)

Morris, Simon, Content, Robert, Sharples, Ray, Bower, Richard, Davies, Roger, Baugh, Carlton

We describe an instrument concept that will provide simultaneous spectra for a million spatial samples on the sky. With the proposed field of view and spectral resolution, it will be able to measure...

Globular Clusters as Probes of the Virgo gE NGC 4472 (2000)

Bridges, Terry, Ashman, Keith, Beasley, Mike, Sharples, Ray, Geisler, Doug, Hanes, Dave, ...

We present radial velocities for 144 globular clusters around the Virgo gE NGC 4472 (M49), and ages and metallicities from co-added spectra of 131 clusters. We confirm our earlier finding that the...

Multiple object and integral field near-infrared spectroscopy using fibers (1999)

Haynes, Roger, Lee, David, Allington-Smith, Jeremy, Content, Robert, Dodsworth, George, Lewis, Ian, ...

We describe a new system for multiple object spectroscopy and integral field spectroscopy at near-infrared wavelengths using optical fibers. Both modes of the SMIRFS instrument have been tested at...
