The Mass Structure of the Galaxy Cluster Cl0024+1654 from a Full Lensing Analysis of Joint Subaru and ACS/NIC3 Observations (2009)

Umetsu, Keiichi, Medezinski, Elinor, Broadhurst, Tom, Zitrin, Adi, Okabe, Nobuhiro, Hsieh, Bau-Ching, ...

We derive an accurate mass distribution of the rich galaxy cluster Cl0024+1654 (z=0.395) based on deep Subaru BR_{c}z' imaging and our recent comprehensive strong lensing analysis of HST/ACS/NIC3...

Detailed Cluster Mass and Light profiles of A1703, A370 and RXJ1347-11 from Deep Subaru Imaging (2009)

Medezinski, Elinor, Broadhurst, Tom, Umetsu, Keiichi, Oguri, Masamune, Rephaeli, Yoel, Benítez, Narciso

We carefully examine the luminous content of three high mass clusters, A1703 (z=0.258), A370 (z=0.375) and RXJ1347-11 (z=0.45), with deep Subaru imaging. Accurate three-colour data allows us to...

New Multiply-Lensed Galaxies Identified in ACS/NIC3 Observations of Cl0024+1654, Using an Improved Mass Model (2009)

Zitrin, Adi, Broadhurst, Tom, Umetsu, Keiichi, Coe, Dan, Benítez, Narciso, Ascaso, Begoña, ...

We present an improved strong-lensing analysis of Cl0024+1654 ($z$=0.39) using deep HST/ACS/NIC3 images, based on 33 multiply-lensed images of 11 background galaxies. These are found with a model...

Preprint typeset using LATEX style emulateapj v. 10/10/03 MASS AND HOT BARYONS IN MASSIVE GALAXY CLUSTERS FROM SUBARU WEAK LENSING AND AMIBA SZE OBSERVATIONS 1 (2009)

Keiichi Umetsu, Mark Birkinshaw, Guo-chin Liu, Elinor Medezinski, Tom Broadhurst, ...

We present a multiwavelength analysis of a sample of four hot (TX> 8keV) X-ray galaxy clusters (A1689, A2261, A2142, and A2390) using joint AMiBA Sunyaev-Zel’dovich effect (SZE) and Subaru weak...

Mass and Hot Baryons in Massive Galaxy Clusters from Subaru Weak Lensing and AMiBA SZE Observations (2008)

Umetsu, Keiichi, Birkinshaw, Mark, Liu, Guo-Chin, Wu, Jiun-Huei Proty, Medezinski, Elinor, Broadhurst, Tom, ...

We present a multiwavelength analysis of a sample of four hot (T_X>8keV) X-ray galaxy clusters (A1689, A2261, A2142, and A2390) using joint AMiBA Sunyaev-Zel'dovich effect (SZE) and Subaru weak...

Comparison of Cluster Lensing Profiles with Lambda CDM Predictions (2008)

Broadhurst, Tom, Umetsu, Keiichi, Medezinski, Elinor, Oguri, Masamune, Rephaeli, Yoel

We derive lens distortion and magnification profiles of four well known clusters observed with Subaru. Each cluster is very well fitted by the general form predicted for Cold Dark Matter (CDM)...

Using Weak Lensing Dilution to Improve Measurements of the Luminous and Dark Matter in A1689 (2006)

Medezinski, Elinor, Broadhurst, Tom, Umetsu, Keiichi, Coe, Dan, Benitez, Narciso, Ford, Holland, ...

The E/SO sequence of a cluster defines a boundary redward of which a reliable weak lensing signal can be obtained from background galaxies, uncontaminated by cluster members. For bluer colors, both...
