MACs: Multi-Attribute Co-clusters with High Correlation Information
[chapter]
2009
Lecture Notes in Computer Science
Preserved Fulltext
The generalized formula enables us to use correlation information to discover multi-attribute co-clusters (MACs). ...
We develop a novel algorithm MACminer to mine MACs with high correlation information from datasets. ...
(b) Multi-attribute co-clustering. The pair of clusters with horizontal lines form a multi-attribute co-cluster, and so do the pair of clusters with vertical lines. ...

We present high resolution (9^") imaging of the Sunyaev-Zel'dovich Effect (SZE) toward two massive galaxy clusters, MACS J0647.7+7015 (z=0.591) and MACS J1206.2-0847 (z=0.439). ...
For MACS J0647.7+7015, we find a gNFW profile with core slope parameter γ= 0.9 fits the MUSTANG image with χ^2_red=1.005 and probability to exceed (PTE) = 0.34. ...

Our observations have also revealed an ongoing second merger along with a close-by high-speed (1769±^148_359 km s^-1) merger-shock (M=2.02±^17_41), thus providing a possible clue to the halo-relic co-existence ...
Here we present GMRT dual-band (235 and 610 MHz) radio observations of four such merging cluster candidates from the MAssive Cluster Survey (MACS) catalogue. ...
This also informs us about a galaxy cluster merger that has taken place at such an early stages (at high redshift) of structure formation in the Universe. ...

Our Chandra observation of the system yields a total X-ray luminosity of 2.4 x 10^45 erg/s (0.1-2.4 keV) and a global gas temperature of (11.6 +/- 0.7) keV, very high values typical of MACS clusters. ...

For each cluster, our best-fit mass model consists of a single cluster-scale halo, and 57 (170) galaxy-scale halos for MACS J0242 (MACS J0949). ...
