The IRAS PSCz Dipole
M. Rowan-Robinson, J. Sharpe, S. J. Oliver +12
We use the PSCz IRAS galaxy redshift survey to analyze the cosmological galaxy dipole out to a distance 300 h Mpc. The masked area is filled in three different ways, firstly…
Total intensity and polarized emission of the parsec-scale jet in 3C345
E. Ros, J. A. Zensus, A. P. Lobanov
We have studied the parsec-scale structure of the quasar 3C345 at λλ1.3, 2, 3.6, and 6 cm, using total intensity and linear polarization images from 3 epochs of VLBA observations m…
The puzzling theoretical predictions for the luminosity of clumping He burning stars
V. Castellani, S. Degl'Innocenti, L. Girardi +3
This paper deals with theoretical predictions for He burning models in a range of masses covering the so-called Red Giant Branch phase transition. Taking as a guideline the observa…
Evidence for X-ray emission from a large-scale filament of galaxies ?
Caleb Scharf, Megan Donahue, G. Mark Voit +2
Cosmological simulations predict that a large fraction of the baryonic mass of the Universe exists as 10^5-10^7 K diffuse, X-ray emitting gas, tracing low density filament and shee…
ROSAT PSPC observations of T Tauri stars in MBM12
T. Hearty, R. Neuhauser, B. Stelzer +4
We present the ROSAT PSPC pointed and ROSAT All-Sky Survey (RASS) observations and the results of our low and high spectral resolution optical follow-up observations of the T Tauri…
X-ray/TeV-gamma-ray observations of several strong flares of Mkn 501 during 1997 and implications
H. Krawczynski, P. S. Coppi, T. Maccarone +1
During more than 6 months in 1997, the BL Lac object Mkn 501 was in an exceptionally bright state, both in the X-ray band and in the Very High Energy (VHE) band. In this paper we p…
