Evolution of the Early-Type Galaxy Fraction in Clusters since z = 0.8 (2009)

Simard, Luc, Clowe, Douglas, Desai, Vandana, Dalcanton, Julianne J., Von Der Linden, Anja, Poggianti, Bianca M., ...

We study the morphological content of a large sample of high-redshift clusters to determine its dependence on cluster mass and redshift. Quantitative morphologies are based on bulge+disk...

The evolution of early and late type galaxies in the COSMOS up to z~1.2 (2009)

Pannella, Maurilio, Gabasch, Armin, Goranova, Yuliana, Drory, Niv, Hopp, Ulrich, Noll, Stefan, ...

The Cosmic Evolution Survey (COSMOS) allows for the first time a highly significant census of environments and structures up to redshift one, as well as a full morphological description of the galaxy...

Frequency and properties of bars in cluster and field galaxies at intermediate redshifts (2009)

Barazza, Fabio D., Jablonka, Pascale, Desai, Vandana, Jogee, Shardha, Aragon-Salamanca, Alfonso, De Lucia, Gabriella, ...

We present a study of large-scale bars in field and cluster environments out to redshifts of ~0.8 using a final sample of 945 moderately inclined disk galaxies drawn from the EDisCS project. We...

Dark matter content and internal dynamics of NGC 4697: NMAGIC particle models from slit data and planetary nebulae velocities (2008)

De Lorenzi, Flavio, Gerhard, Ortwin, Saglia, Roberto P., Sambhus, Niranjan, Debattista, Victor P., Pannella, Maurilio, ...

We present a dynamical study of NGC 4697, an almost edge-on, intermediate-luminosity, E4 elliptical galaxy, combining new surface brightness photometry, new as well as published long-slit absorption...

Spectroscopy of clusters in the ESO distant cluster survey (EDisCS).II. Redshifts, velocity dispersions, and substructure for clusters in the last 15 fields (2008)

Milvang-Jensen, Bo, Noll, Stefan, Halliday, Claire, Poggianti, Bianca M., Jablonka, Pascale, Aragon-Salamanca, Alfonso, ...

AIMS. We present spectroscopic observations of galaxies in 15 survey fields as part of the ESO Distant Cluster Survey (EDisCS). We determine the redshifts and velocity dispersions of the galaxy...

1 (2007)

Thomas H. Puzia, Roberto P. Saglia, Markus Kissler-patig, Claudia Maraston, Laura Greggio, Alvio Renzini, ...

Abstract. We present a comprehensive spectroscopic study of the integrated light of metal-rich Galactic globular clusters and the stellar population in the Galactic bulge. We measure line indices...

The build-up of the colour-magnitude relation in galaxy clusters since z~0.8 (2006)

De Lucia, Gabriella, Poggianti, Bianca M., Aragon-Salamanca, Alfonso, White, Simon D. M., Zaritsky, Dennis, Clowe, Douglas, ...

Using galaxy clusters from the ESO Distant Cluster Survey, we study how the distribution of galaxies along the colour-magnitude relation has evolved since z~0.8. While red-sequence galaxies in all...

VLT Spectroscopy of Globular Cluster Systems, II. Spectroscopic Ages, Metallicities, and [alpha/Fe] Ratios of Globular Clusters in Early-Type Galaxies (2005)

Puzia, Thomas H., Kissler-Patig, Markus, Thomas, Daniel, Maraston, Claudia, Saglia, Roberto P., Bender, Ralf, ...

An analysis of ages, metallicities, and [alpha/Fe] ratios of globular cluster systems in early-type galaxies is presented, based on Lick index measurements summarized in Puzia et al. (2004, Paper I...

Integrated Spectroscopy of Bulge Globular Clusters and Fields I. The Data Base and Comparison of Individual Lick Indices in Clusters and Bulge (2002)

Puzia, Thomas H., Saglia, Roberto P., Kissler-Patig, Markus, Maraston, Claudia, Greggio, Laura, Renzini, Alvio, ...

We present a comprehensive spectroscopic study of the integrated light of metal-rich Galactic globular clusters and the stellar population in the Galactic bulge. We measure line indices which are...

Elliptical Galaxies: Detailed Structure, Scaling Relations and Formation (1998)

Bender, Ralf, Saglia, Roberto P.

The last decade of research on elliptical galaxies has produced a wealth of new information concerning both their detailed structure and their global scaling relations. We review the old and new...

The kinematically peculiar cores of the Coma cluster early -- type galaxies NGC 4816 and IC 4051 (1997)

Mehlert, Doerte, Saglia, Roberto P., Bender, Ralf, Wegner, Gary

The Coma cluster is one of the richest known cluster of galaxies, spanning about 4 dex in density. Hence it is the ideal place to study the structure of galaxies as a function of environmental...

Spectroscopic Gradients in Early -- Type Galaxies and Implications on Galaxy Formation (1997)

Mehlert, Dörte, Bender, Ralf, Saglia, Roberto P., Wegner, Gary

The Coma cluster is the ideal place to study galaxy structure as a function of environmental density in order to constrain theories of galaxy formation and evolution. Here we present the spectroscopy...
