... Galaxies rotate and move in clusters as if a tremendous amount of unseen matter is present. But does dark matter exist in the greater universe too -- and if so, where? ...

K-band Arcetri Obscured Supernova Search . What is the KAOSS Project? W hat is the KAOSS Project? Some recent surveys aimed at detecting Supernovae (SNe) in the optical have found that starburst galaxies do not show evidence for an enhanced SN rate, with respect to quiescent galaxies (Richmond et al. ... A similar result was obtained by Navasardyan et al. (2001) who looked for SNe in interacting galaxies, finding no evidence for correlations between SN rate and galaxy properties. ...

Study of galaxies in a nearby Lynx-Cancer Void: project and first results Pustilnik S.A. and Tepliakova A.L. (SAO) Dwarf galaxies residing in the very low density environment (voids) are expected in the frame of modern cosmological CDM models to form later and to evolve more slowely in respect of their counterparts in a more typical environment. The available data on evolution of void population are rather scarce and indirect. ...

View from Armagh looking towards the North-West at 10.00 p.m. on 30th March 1997. The comet is best seen with binoculars, but viewed with the naked eye both the head and tail should be easily visible. To get your bearings, note the bright star Capella, in the constellation of Auriga high in the west, the prominent "W" of stars that make up the constellation of Cassiopeia, and the outline of Perseus. ... Viewed with the naked eye the Pleiades cluster appears as a haze of stars. ...

... We present a photometric and spectroscopic study of the unique isolated nearby galaxy KKR25. The isolated dwarf spheroidal (dSph) galaxy KKR25 was discovered by Karachentseva, Karachentsev Richter (1999, A , 135, 221) during the search of dwarf galaxies in the direction of the Local Void. In spite of its isolation KKR 25 has no gas and looks like a normal dwarf spheroidal system. ... This is the first known planetary nebula in a dwarf spheroidal galaxy outside the Local Group. ...

... Clustering of AGN and QSOs at z=1 . Using galaxies from the DEEP2 Redshift Survey and AGN from the AEGIS/Chandra survey and QSOs from SDSS, I present the cross-correlation function of AGN/QSOs and 'normal' galaxies at z=1. Using the known clustering of DEEP2 galaxies, this leads to an estimate of the bias and typical host dark matter halo mass of AGN/QSOs as a function of X-ray luminosity, which constrains AGN formation models. oral . ...

... arXiv.org . astro-ph . ... We fit the near-infrared to radio spectral energy distributions of 30 luminous and ultra-luminous infrared galaxies with pure starburst models or models that include both starburst and AGN components to determine important physical parameters for this population of objects. In particular we constrain the optical depth towards the luminosity source, the star formation rate, the star formation efficiency and the AGN fraction. ...

... Table of Contents - Index - PS reprint - PDF reprint . ... All RXTE telemetry will be archived in a hierarchical database consisting entirely of FITS Binary Tables. We describe an interactive tool, the XTE Data Finder (XDF). ... Our basic design contains a three level hierarchy: Master Index, Subsystem Index, and Data Table. ... The Master Index acts as an observation catalog with references to Subsystem Indices, while the latter contain configuration information and references to the Data Tables. ...
