On Planck simulations: towards `2-nd order' analyses
C. Burigana, D. Maino, N. Mandolesi +6
We simulate Planck observations by adopting a detailed model of the microwave sky including monopole, dipole, anisotropies of the cosmic microwave background (CMB) and galactic and…
Extragalactic Radio Sources and CMB anisotropies
L. Toffolatti, G. De Zotti, F. Argüeso +1
Confusion noise due to extragalactic sources is a fundamental astrophysical limitation for experiments aimed at accurately determining the power spectrum of the Cosmic Microwave Ba…
The HI fine structure of HVC187 near NGC3783, gas in the leading bridge of the Magellanic System
B. P. Wakker, B. D. Savage, T. A. Oosterloo +1
We present an analysis of high-resolution HI data of one of the cores of HVC187 Wakker & van Woerden 1991), HVC287+22+240. Structure is present down to the lowest-measurable scale…
Progressive covering in dipping and Comptonization in the spectrum of XB1916-053 from the BeppoSAX observation
M. J. Church, A. N. Parmar, M. Balucinska-Church +3
We report results of a BeppoSAX observation of the low-mass X-ray binary (LMXB) dipping source XB 1916-053. The source joins the small group of LMXB detected at energies ~100 keV.…
Isotopic composition of Hg and Pt in slowly rotating HgMn stars
S. Hubrig, F. Castelli, G. Mathys
Preliminary results from a study of the isotopic compositions of the elements Hg and Pt in a number of HgMn stars are presented. This work represents an improvement over previous s…
High resolution imaging of the X-ray afterglow of GRB970228 with ROSAT
F. Frontera, J. Greiner, L. A. Antonelli +6
We report results of a ROSAT High-Resolution Imager (HRI) observation of the X-ray error box given by the BeppoSAX Wide Field Camera for the gamma-ray burst that occurred on 1997 F…
