Limits on dark matter WIMPs using upward-going muons in the MACRO detector
The MACRO Collaboration, M. Ambrosio et al
We perform an indirect search for Weakly Interacting Massive Particles (WIMPs) using the MACRO detector to look for neutrino-induced upward-going muons resulting from the annihilat…
BeppoSAX observations of an orbital cycle of the X-ray binary pulsar GX301-2
M. Orlandini, D. Dal Fiume, F. Frontera +4
We present preliminary results on our campaign of observations of the X-ray binary pulsar GX301-2. BeppoSAX observed this source six times in January/February 1998: at the periastr…
Probing the Cosmic Large-Scale Structure with the REFLEX Cluster Survey : Profile of an ESO Key Programme
H. Böhringer, L. Guzzo, C. A. Collins +11
The paper describes the goals and first results of the ROSAT ESO Flux-Limited X-ray (REFLEX) Cluster Survey, a redshift survey of the X-ray brightest galaxy clusters in the ROSAT A…
Results from the REFLEX Cluster Survey
H. Böhringer, L. Guzzo, C. A. Collins +11
Based on the ROSAT All-Sky Survey we have conducted a large redshift survey as an ESO key programme to identify and secure redshifts for the X-ray brightest clusters found in the s…
BeppoSAX Observations of Bright Seyfert 2 Galaxies: Measuring the Intrinsic Continuum Emission
L. Bassani, M. Cappi, G. Malaguti +19
We report broad band (0.1-200 keV) X-ray observations, made by BeppoSAX, of a sample of bright Seyfert 2 galaxies: NGC7172, NGC2110, NGC4507, Mkn 3 and NGC7674. These spectra provi…
Diffuse Thermal Emission from Very Hot Gas in Starburst Galaxies: Spectral Results
M. Cappi, M. Persic, S. Mariani +12
New BeppoSAX observations of the nearby archetypical starburst galaxies (SBGs) NGC253 and M82 are presented. The main observational result is the unambiguous evidence that the hard…
