The Pisces-Cetus Supercluster: a remarkable filament of galaxies in the 2dF Galaxy Redshift Survey and Sloan Digital Sky surveys
Scott C. Porter, Somak Raychaudhury
The Pisces-Cetus supercluster (redshift z~0.06) is one of the richest nearby (z<0.1) superclusters of galaxies, and emerges as a remarkable filament of galaxies at the edges of the…
X-ray observations of the edge-on star-forming galaxy NGC891 and its supernova SN1986J
Rowan Temple, Somak Raychaudhury, Ian Stevens
We present XMM-Newton observations of NCG891, a nearby edge-on spiral galaxy. We analyse the extent of the diffuse emission emitted from the disk of the galaxy, and find that it ha…
A Chandra Observation of the Nearby Lenticular Galaxy NGC 5102: Where are the X-ray Binaries?
R. P. Kraft, L. A. Nolan, T. J. Ponman +2
We present results from a 34 ks Chandra/ACIS-S observation of the nearby (d=3.1 Mpc) lenticular galaxy NGC 5102, previously shown to have an unusually low X-ray luminosity. We dete…
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…
