Galaxies In X-Ray Groups. I. Robust Membership Assignment And The Impact Of Group Environments On Quenching

Jean-Paul Richard Kneib

Understanding the mechanisms that lead dense environments to host galaxies with redder colors, more spheroidal morphologies, and lower star formation rates than field populations remains an important problem. As most candidate processes ultimately depend o ...

SPACE: the spectroscopic all-sky cosmic explorer

Rachel Grange, Herbert Shea, Stewart Cole, Fabio Finelli, Jean-Paul Richard Kneib, Yi Wang

We describe the scientific motivations, the mission concept and the instrumentation of SPACE, a class-M mission proposed for concept study at the first call of the ESA Cosmic-Vision 2015–2025 planning cycle. SPACE aims to produce the largest three-dimensio ...

A new window of exploration in the mass spectrum: strong lensing by galaxy groups in the SL2S

Johan Richard, Jean-Paul Richard Kneib

The existence of strong lensing systems with Einstein radii covering the full mass spectrum, from similar to 1-2 '' (produced by galaxy scale dark matter haloes) to >10 '' (produced by galaxy cluster scale haloes) have long been predicted. Many lenses with ...

COSMOS 5921+0638: characterization and analysis of a new strong gravitationally lensed AGN

Jean-Paul Richard Kneib

Context. Strong lens candidates have been newly identified within the COSMOS field. We present VLT/FORS1 spectroscopic follow-up observations and HST/WFPC2 imaging of the system COSMOS 5921+0638, which exhibits quadruply lensed images and a perfect Einstei ...

Redshifts and lens profile for the double quasar QJ 0158-4325

Alexander Patrick Eigenbrod, Jean-Paul Richard Kneib

Aims. We report on the redshift of the lensing galaxy and of the quasar QJ 0158-4325 and on the lens model of the system. ...

On The Contribution Of Large-Scale Structure To Strong Gravitational Lensing

Jean-Paul Richard Kneib, Richard Massey

We study the correlation between the locations of galaxy-galaxy strong-lensing candidates and tracers of large-scale structure from both weak lensing (WL) or X-ray emission. The Cosmological Evolution Survey (COSMOS) is a unique data set, combining deep, h ...

ZEN2: a narrow J-band search for z similar to 9 Ly alpha emitting galaxies directed towards three lensing clusters

Frédéric Courbin, Jean-Paul Richard Kneib

We present the results of a continuing survey to detect Ly alpha emitting galaxies at redshifts z similar to 9: the z equals nine' (ZEN) survey. We have obtained deep VLT Infrared Spectrometer and Array Camera observations in the narrow J-band filter NB119 ...
