Constraining the Redshift Evolution of FIRST Radio Sources in RCS1 Galaxy Clusters

, 2010
We conduct a statistical analysis of the radio source population in galaxy clusters as a function of redshift by matching radio sources from the Faint Images of the Radio Sky at Twenty-Centimeters (FIRST) catalog with 618 optically-selected galaxy ...

Near-IR search for lensed supernovae behind galaxy clusters: III. Implications for cluster modeling and cosmology

, 2011
Massive galaxy clusters at intermediate redshifts act as gravitational lenses that can magnify supernovae (SNe) occurring in background galaxies. We assess the possibility to use lensed SNe to put constraints on the mass models of galaxy clusters and the

A catalog of Nearby Poor Clusters of Galaxies [PDF]

, 1999
A catalog of 732 optically selected, nearby poor clusters of galaxies covering the entire sky north of $\rm -3^{\circ}$ declination is presented. The poor clusters, called WBL clusters, were identified as concentrations of 3 or more galaxies with ...

Clustering of Submillimetre-Selected Galaxies [PDF]

The Astrophysical Journal, 2004
Using accurate positions from very deep radio observations to guide multi-object Keck spectroscopy, we have determined a substantially complete redshift distribution for very luminous, distant submillimeter(submm)-selected galaxies (SMGs). A sample of 73 redshifts for SMGs in 7 fields contains a surprisingly large number of `associations': systems of ...

Controlling 3D Contractility via Engineered Fibrous Hydrogel Composites

Advanced Functional Materials, EarlyView.
A tunable composite contractile assembly (CCA) is developed that can permit or resist contraction without changing cell‐adhesion and density, unlike collagen whose inherent coupling of these ECM cues limits its use as a platform in contractility studies.

Galaxy Cluster Environments of Radio Sources

, 2011
Using the Sloan Digital Sky Survey (SDSS) and the FIRST (Faint Images of the Radio Sky at Twenty Centimeters) catalogs, we examined the optical environments around double-lobed radio sources. Previous studies have shown that multi-component radio sources

Supermodel Analysis of Galaxy Clusters [PDF]

AIP Conference Proceedings, 2009
[abridged] We present the analysis of the X-ray brightness and temperature profiles for six clusters belonging to both the Cool Core and Non Cool Core classes, in terms of the Supermodel (SM) developed by Cavaliere, Lapi & Fusco-Femiano (2009). Based on the gravitational wells set by the dark matter halos, the SM straightforwardly expresses the ...
