XMM AO15 proposal: X-ray large scale survey of the nearby galaxy cluster Abell2199

2015-10: Submitted.

We use XMM to map the cluster Abell 2199 intermediate region (<3 p="" virial="">radius) and search X-ray faint substructures in a wide spacial range from
a galaxy to a cluster and larger sizes. We observed this area with SUZAKU
and found a number of structures and a hint of asymmetric large scale emission.
These substructures along with unresolved background sources should be
resolved spatially and covered fully with XMM imaging. Errors of the EPIC
background will be reduced by our SUZAKU deep spectra. These X-ray maps will
be compared with our wide area weak-lensing data observed with SUBARU Hyper
suprime-Cam. The XMM observations provide uniquely a direct comparison among
structures of galaxies, ICM, and dark matter.

Suzaku AO10 proposal: 2D Mapping of Abell2199

We have performed a Suzaku key project, "Distribution of Temperature and Entropy of Intracluster Medium of nearby clusters up to Virial Radius" in AO6 and observed the galaxy cluster Abell2199. This along with other pointings covers a large area reaching to the virial radius. We propose to complete this mapping by additional 10 pointings. This provides a wide, deep and complete X-ray view of a nearby relaxed cluster. This should be the highest quality cluster data set in the Suzaku archive. We measure the two-dimensional and large-scale properties of the ICM to understand thermal history of large-scale structure formation.We also compare the ICM distribution with our deep galaxy catalog and probe local and global galaxy-ICM interations.

suzaku AO9: 2D Mapping of Abell~2199

A suzaku proposal for AO9.

We have performed a Suzaku key project, "Distribution of Temperature and Entropy of Intracluster Medium of nearby clusters up to Virial Radius" in AO6 and observed the galaxy cluster Abell2199. This covers a large area reaching to the virial radius in 16 pointings. We propose to complete this mapping by additional 8 pointings. This provides a deep, wide and complete X-ray view of a nearby relaxed cluster. This should be highest quality cluster data set in the Suzaku archive. We measure the two-dimensional properties of the ICM, compare it with galaxy distribution, and study dynamical history of structure formation.
