Robust mixtures in the presence of measurement errors
Jianyong Sun, Ata Kaban, Somak Raychaudhury
We develop a mixture-based approach to robust density modeling and outlier detection for experimental multivariate data that includes measurement error information. Our model is de…
The Representative XMM-Newton Cluster Structure Survey (REXCESS) of an X-ray Luminosity Selected Galaxy Cluster Sample
H. Boehringer, P. Schuecker, G. W. Pratt +31
The largest uncertainty for cosmological studies using clusters of galaxies is introduced by our limited knowledge of the statistics of galaxy cluster structure, and of the scaling…
Star formation in galaxies along the Pisces-Cetus Supercluster filaments
Scott C. Porter, Somak Raychaudhury
We investigate the variation of current star formation in galaxies as a function of distance along three supercluster filaments, each joining pairs of rich clusters, in the Pisces-…
Finding Young Stellar Populations in Elliptical Galaxies from Independent Components of Optical Spectra
Ata Kaban, Louisa A. Nolan, Somak Raychaudhury
Elliptical galaxies are believed to consist of a single population of old stars formed together at an early epoch in the Universe, yet recent analyses of galaxy spectra seem to ind…
