Luminosity Functions of XMM-LSS C1 Galaxy Clusters (2009)

Alshino, Abdulmonem, Khosroshahi, Habib, Ponman, Trevor, Willis, Jon, Pierre, Marguerite, Pacaud, Florian, ...

CFHTLS optical photometry has been used to study the galaxy luminosity functions of 14 X-ray selected clusters from the XMM-LSS survey. These are mostly groups and poor clusters, with masses...

Combined analysis of weak lensing and X-ray blind surveys (2008)

Bergé, Joel, Pacaud, Florian, Réfrégier, Alexandre, Massey, Richard, Pierre, Marguerite, Amara, Adam, ...

We present a joint weak lensing and X-ray analysis of 4 deg^2 from the CFHTLS and XMMLSS surveys. Our weak lensing analysis is the first analysis of a real survey using shapelets, a new generation...

Combined analysis of weak lensing and X-ray blind surveys (2007)

Bergé, Joel, Pacaud, Florian, Réfrégier, Alexandre, Massey, Richard, Pierre, Marguerite, Amara, Adam, ...

We present a joint weak lensing and X-ray analysis of 4 deg$^2$ from the CFHTLS and XMM-LSS surveys. Our weak lensing analysis is the first analysis of a real survey using shapelets, a new generation...

First Insights into the Spitzer Wide-Area Infrared Extragalactic Legacy Survey (SWIRE) Galaxy Populations (2004)

Lonsdale, Carol, Polletta, Maria Del Carmen, Surace, Jason, Shupe, Dave, Fang, Fan, Xu, C. Kevin, ...

We present sub-millimeter statistical detections of galaxies discovered in the 5'x5' Spitzer Early Release Observations (to 4-15 microJy 5 sigma at 3.6-8 microns, 170 microJy at 24 microns) through a...

First Insights into the SWIRE Galaxy Populations (2004)

Lonsdale, Carol, Polletta, Maria, Surace, Jason, Shupe, David, Fang, Fan, Xu, C. Kevin, ...

We characterize the SWIRE galaxy populations in the SWIRE validation field within the Lockman Hole, based on the 3.6-24$\mu$ Spitzer data and deep U,g',r',r' optical imaging within an area ~1/3 sq....

X-ray Cluster Large Scale Structure and Cosmology (2003)

Pierre, Marguerite

We outline main arguments in favor of cosmological X-ray surveys of galaxy clusters. We summarize recent advances in our understanding of cluster physics. After a short review of past surveys, we...

SWIRE: The SIRTF Wide-Area Infrared Extragalactic Survey (2003)

Lonsdale, Carol J., Smith, Harding E., Rowan-Robinson, Michael, Surace, Jason, Shupe, David, Xu, Cong, ...

The SIRTF Wide-Area Infrared Extragalactic Survey (SWIRE), the largest SIRTF Legacy program, is a wide-area imaging survey to trace the evolution of dusty, star-forming galaxies, evolved stellar...

SWIRE: The SIRTF Wide-area InfraRed Extragalactic Survey (2003)

Lonsdale, Carol J., Smith, Harding E., Rowan-Robinson, Michael, Surace, Jason, Shupe, David, Xu, Cong, ...

The SIRTF Wide-area InfraRed Extragalactic survey (SWIRE), the largest SIRTF Legacy program, is a wide-area, imaging survey to trace the evolution of dusty, star-forming galaxies, evolved stellar...

The XMM-LSS Survey: Mapping hot, luminous, obscured and dark material out to z~1-2 (2001)

Pierre, Marguerite

We review the unique cosmological implications of the XMM-LSS survey in association with its multi-WL follow-up: (1) Large Scale Structures traced by X-ray clusters and AGNs, optical galaxies, weak...

Cosmology with Galaxy Clusters in the XMM Large-Scale Structure Survey (2001)

Refregier, Alexandre, Valtchanov, Ivan, Pierre, Marguerite

The upcoming XMM Large Scale Structure Survey (XMM-LSS) will ultimately provide a unique mapping of the distribution of X-ray sources in a contiguous 64 sq. deg. region. In particular, it will...

Structure Detection in Low Intensity X-Ray Images (1997)

Starck, Jean-Luc, Pierre, Marguerite

In the context of assessing and characterizing structures in X-ray images, we compare different approaches. Most often the intensity level is very low and necessitates a special treatment of Poisson...

X-ray structures in galaxy cluster cores (1997)

Pierre, Marguerite, Starck, Jean-Luc

Using a set of ROSAT HRI deep pointings, we investigate the presence of small-scale structures in the central regions of clusters of galaxies. Our sample comprises 23 objects up to z=0.32, 13 of them...
