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.

These are 602 570 optical objects which are associated to radio/X-ray detections from the NVSS, FIRST, SUMSS, XMM, Chandra, or ROSAT RASS, PSPC, HRI and WGA survey catalogs. All association detections are shown, across all these catalogs. Also displayed: the calculated probability that the optical object is in turn a quasar, galaxy, star, or erroneous association. The optical object is identified from the literature, if known.

Useful data from a large set of catalogs.

I will use this for identification of X-ray observations of Abell2199.

銀河団外縁部のエントロピー異常の原因の検証

銀河団は大規模構造からの質量降着によって現在も成長していると考えられている。宇宙論的シミュレーショ ンでは、質量降着時の衝撃波によってエントロピーは半径の 1.1 乗に比例して上昇すると考えられていた。しかし 「すざく」衛星による銀河団外縁部までの観測からエントロピーは r500 までしか上昇せず、以降はほぼ一定の値 となることが確認された (e.g., Sato et al. 2012)。 異常の原因の一つとして外縁部の高温ガスの密度むらによっ て密度を過大評価していることが挙げられている (Simionescu et al. 2011)。降着してきたガス塊が銀河団ガスと 十分混ざっていない場合外縁部のガス密度にはむらが生じる。そのためガス塊の存在が確認出来れば密度が受ける影響を評価し得る。ガス塊が十分大きく明るい場合周囲よりも明るい X 線源として観測出来る可能性がある。 近傍の中規模銀河団Abell 2199 (z=0.03, kT=4 keV)は南北に延びるフィラメント上に位置しており、外縁部 でのエントロピー異常を我々は既に報告した (佐藤他、2012 年春季年会)。今回、Abell 2199 銀河団の外縁部に ついて「すざく」衛星によるビリアル半径付近までのマッピング観測に加えて「XMM-Newton」衛星でフィラ メント方向を含む 2 領域を新たに観測した。銀河団外縁部での X 線点源数 (logN-logS 関係) を Lockman hole, COSMOS 領域など、明るい天体のいない領域と比較したところ両者と良く一致した。ただし、検出された X 線 源について詳細なスペクトル解析を行ったところ、少数ながら1-3 keVの熱的プラズマからのスペクトルを示すX 線源が存在した。本講演ではガス塊による密度むらがエントロピーにどれだけ影響し得るかについて議論する。

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.
