The mass profile and dynamical status of the z~0.8 galaxy cluster LCDCS 0504
L. Guennou, A. Biviano, C. Adami +34
Constraints on the mass distribution in high-redshift clusters of galaxies are not currently very strong. We aim to constrain the mass profile, M(r), and dynamical status of the $z…
Structure and substructure analysis of DAFT/FADA galaxy clusters in the [0.4-0.9] redshift range
L. Guennou, C. Adami, F. Durret +29
We analyse the structures of all the clusters in the DAFT/FADA survey for which XMM-Newton and/or a sufficient number of galaxy redshifts in the cluster range is available, with th…
The baryon budget on the galaxy group/cluster boundary
Alastair J. R. Sanderson, Ewan O'Sullivan, Trevor J. Ponman +4
We present a study of the hot gas and stellar content of 5 optically-selected poor galaxy clusters, including a full accounting of the contribution from intracluster light (ICL) an…
Cl 1103.7-1245 at z=0.96: the highest redshift galaxy cluster in the EDisCS survey
Benedetta Vulcani, Alfonso Aragón-Salamanca, Bianca M. Poggianti +6
We present new spectroscopic observations in a field containing the highest redshift cluster of the ESO Distant Cluster Survey (EDisCS). We measure galaxy redshifts and determine t…
Evolution of the Red Sequence Giant to Dwarf Ratio in Galaxy Clusters out to z ~ 0.5
C. Bildfell, H. Hoekstra, A. Babul +9
We analyze deep g' and r' band data of 97 galaxy clusters imaged with MegaCam on the Canada-France-Hawaii telescope. We compute the number of luminous (giant) and faint (dwarf) gal…
Detection of Outflowing and Extraplanar Gas in Disks in an Assembling Galaxy Cluster at z=0.37
E. Freeland, K-V. Tran, T. Irwin +5
We detect ionized gas characteristics indicative of winds in three disk-dominated galaxies that are members of a super-group at z=0.37 that will merge to form a Coma-mass cluster.…
Intracluster light in clusters of galaxies at redshifts 0.4<z<0.8
L. Guennou, C. Adami, C. Da Rocha +27
The study of intracluster light can help us to understand the mechanisms taking place in galaxy clusters, and to place constraints on the cluster formation history and physical pro…
How Typical Are The Local Group Dwarf Galaxies?
Daniel R. Weisz, Andrew E. Dolphin, Julianne J. Dalcanton +11
We compare the cumulative star formation histories (SFHs) of Local Group (LG) dwarf galaxies with those in the volume-limited ACS Nearby Galaxy Survey Treasury (ANGST) sample (D <…
The fundamental plane of EDisCS galaxies - The effect of size evolution
R. P. Saglia, P. Sanchez-Blazquez, R. Bender +15
We study the evolution of spectral early-type galaxies in clusters, groups and the field up to redshift 0.9 using the EDisCS dataset. We measure Re, Ie, and sigma for 154 cluster a…
A Deeper Look at Leo IV: Star Formation History and Extended Structure
D. J. Sand, A. Seth, E. W. Olszewski +3
We present MMT/Megacam imaging of the Leo~IV dwarf galaxy in order to investigate its structure and star formation history, and to search for signs of association with the recently…
Photometric redshifts and cluster tomography in the ESO Distant Cluster Survey
R. Pello, G. Rudnick, G. De Lucia +17
This paper reports the results obtained on the photometric redshifts measurement and accuracy, and cluster tomography in the ESO Distant Cluster Survey (EDisCS) fields. Photometric…
Spatially Correlated Cluster Populations in the Outer Disk of NGC 3184
S. Herbert-Fort, D. Zaritsky, J. Moustakas +9
We use deep (~27.5 mag V-band point-source limiting magnitude) V- and U-band LBT imaging to study the outer disk (beyond the optical radius R_25) of the non-interacting, face-on sp…
Evolution of Cluster Red-Sequence Galaxies from redshift 0.8 to 0.4: ages, metallicities and morphologies
P. Sanchez-Blazquez, P. Jablonka, S. Noll +14
We present a comprehensive analysis of the stellar population properties (age, metallicity and the alpha-element enhancement [E/Fe]) and morphologies of red-sequence galaxies in 24…
