Subaru Suprime-Cam Weak Lensing Survey over 33 deg
Under the currently popular CDM model, mass plays the major role in evolution of large scale structure of the universe. In order to examine the paradigm based on observations, it would be ideal to use purely mass selected object catalog. Weak lensing surveys enable a blind search of cluster scale objects, and thus could provide such catalogs. We are working on a weak lensing survey using Subaru...
متن کاملStructure and Population of the Andromeda Stellar Halo from a Subaru/suprime-cam Survey
We present a photometric survey of the stellar halo of the nearest giant spiral galaxy, Andromeda (M31), using Suprime-Cam on the Subaru Telescope. A detailed analysis of V I color-magnitude diagrams of the resolved stellar population is used to measure properties such as line-of-sight distance, surface brightness, metallicity, and age, and these are used to isolate and characterize different c...
متن کاملWeak Lensing and the Sdss
While the strategy for the first applications of weak lensing has been to “go deep” it is equally interesting to use one’s telescope time to instead “go wide”. The Sloan Survey (SDSS) provides a natural framework for a very wide area weak lensing survey. Probing of the mass distribution using the distortion of galaxy image shapes by the intervening gravitational field this mass produces is a po...
متن کاملProbing the Cluster Mass Distribution Using Subaru Weak Lensing Data
We present results from a weak lensing analysis of the galaxy cluster A1689 (z = 0.183) based on deep wide-field imaging data taken with Suprime-Cam on Subaru telescope. A maximum entropy method has been used to reconstruct directly the projected mass distribution of A1689 from combined lensing distortion and magnification measurements of red background galaxies. The resulting mass distribution...
متن کاملA Subaru/suprime-cam Survey of M31’s Spheroid along the South-east Minor Axis
We have used Suprime-Cam on the Subaru Telescope to conduct a V and I-band imaging survey of fields sampling the spheroid of the Andromeda galaxy along its south-east minor axis. Our photometric data are deep enough to resolve stars down to the red clump. Based on a large and reliable sample of red giant stars available from this deep wide-field imager, we have derived metallicity distributions...
