The first method called FLens integrates an inpainting concept to invert the shear field with possible gaps, and a multi-scale entropy denoising proce- dure to remove the noise contained in the final reconstruction, that arises mostly from the random intrinsic shape of the galaxies. The second and third methods are based on a model of the density field made of a multi-scale grid of radial basis functions. In one case, the model parameters are computed with a linear inversion involving a singular value decomposition. In the other case, the model parameters are estimated using a Bayesian MCMC optimization implemented in the lensing software Lenstool. Methods are compared on simulated data with varying galaxy density fields. We pay particular attention to the errors estimated with resampling. We find the multi-scale grid model optimized with MCMC to provide the best results, but at high computational cost, especially when considering resampling.

Une recherche ambitieuse doit se poursuivre. Organisé pour déve- lopper les grands programmes pour le nucléaire et par le nucléaire, le CEA est bien armé pour concevoir et mettre au point les instruments destinés à explorer, en coopération avec les autres organismes de recherche, les confins de l'infiniment petit et ceux de l'infinimenf grand. La recherche fondamentale évolue et par essence ne doit pas avoir de frontières. Le Département d'astrophysique, de physique des particules, de physique nucléaire et de l'instrumentation associée (Dapnia) a été créé pour abolir les cloisons entre la physique nucléaire, la physique des particules et l'as- trophysique, tout en resserrant les liens entre physiciens, ingénieurs et techniciens au sein de la Direction des sciences de la matière (DSM). Le Dapnia est unique par sa pluridisciplinarité. Ce regroupement a permis de lancer des expériences se situant aux frontières de ces disciplines tout en favorisant de nou- velles orientations et les choix vers les programmes les plus prometteurs. Tout en bénéficiant de l'expertise d'autres départements du CEA, la recherche au Dapnia se fait princi- palement au sein de collaborations nationales et internationales. Les équipes du Dapnia, de I'IN2P3 (Institut national de physique nucléaire et de physique des particules) et de l'Insu (Institut national des sciences de l'Univers) se retrouvent dans de nombreuses grandes collaborations internationales, chacun apportant ses compétences spécifiques afin de renforcer l'impact de nos contributions.

    Is the Butcher-Oemler Effect a Function of the Cluster Redshift? S. Andreon

    THE ASTROPHYSICAL JOURNAL, 516:647È659, 1999 May 10 ( 1999. The American Astronomical Society. All rights reserved. Printed in U.S.A. IS THE BUTCHER-OEMLER EFFECT A FUNCTION OF THE CLUSTER REDSHIFT? S. ANDREON Osservatorio Astronomico di Capodimonte, via Moiariello 16, 80131 Napoli, Italy; andreon=na.astro.it AND S. ETTORI Institute of Astronomy, Madingley Road, Cambridge CB3 0HA, England, UK; settori=ast.cam.ac.uk Received 1998 May 29; accepted 1998 December 18 ABSTRACT Using PSPC ROSAT data, we measure the X-ray surface brightness proÐles, size, and luminosity of the Butcher-Oemler (BO) sample of clusters of galaxies. The cluster X-ray size, as measured by the Pet- rosianrg/2 radius, does not change with redshift and is independent of X-ray luminosity. On the other hand, the X-ray luminosity increases with redshift. Considering that fair samples show no evolution, or negative luminosity evolution, we conclude that the BO sample is not formed from the same class of objects observed at di†erent look-back times. This is in conÑict with the usual interpretation of the Butcher-Oemler as an evolutionary (or redshift dependent) e†ect, based on the assumption that we are comparing the same class of objects at di†erent redshifts. Other trends present in the BO sample reÑect selection criteria rather than di†erences in look-back time, as independently conÐrmed by the fact that trends lose strength when we enlarge the sample with an X-rayÈselected sample of clusters. The variety of optical sizes and shapes of the clusters in the Butcher-Oemler sample and the Malmquist-like bias are the reasons for these selection e†ects that mimic the trends usually interpreted as changes due to evolu- tion.

De Petris1, A. Conte1, L. Lamagna1 and S. De Gregori1 1Sapienza University of Rome, Department of Physics, P.le A. Moro, 2 Rome, Italy Accepted for publication in MNRAS ABSTRACT We explore the scaling relation between the flux of the Sunyaev-Zel’dovich (SZ) ef- fect and the total mass of galaxy clusters using already reduced Chandra X-ray data present in the ACCEPT (Archive of Chandra Cluster Entropy Profile Tables) cata- logue. The analysis is conducted over a sample of 226 objects, examining the relatively small scale corresponding to a cluster overdensity equal to 2500 times the critical density of the background universe, at which the total masses have been calculated exploiting the hydrostatic equilibrium hypothesis. Core entropy (K0) is strongly corre- lated with the central cooling time, and is therefore used to identify cooling-core (CC) objects in our sample. Our results confirm the self-similarity of the scaling relation between the integrated Comptonization parameter (Y ) and the cluster mass, for both CC and NCC (non-cooling-core) clusters. The consistency of our calibration with re- cent ones has been checked, with further support for Y as a good mass proxy. We also investigate the robustness of the constant gas fraction assumption, for fixed overden- sity, and of the YX proxy (Kravtsov et al. 2007) considering CC and NCC clusters, again sorted on K0 from our sample.
