Reply to Critical revision of the ZEPLIN-I sensitivity to WIMP interactions
TL;DR: Benoit et al. as mentioned in this paper showed that the ZEPLIN I limit can be explained by misunderstandings of the calibration data and procedure, and a misreading of the data in one of the referenced papers.

TL;DR: ZEPLIN II and ZEPLIN III detectors were designed for direct detection of cold dark matter in the form of Weakly Interacting Massive Particles (WIMP) as mentioned in this paper.
Journal ArticleDOI
Fluctuations in the Diffuse Soft X-ray Background; Probably of Galactic Halo Origin
TL;DR: In this paper, the soft X-ray background data from the ROSAT PSPC was fitted by a model including emission from the local bubble, embedded hot gas within the disk, hot gas in the Galactic halo and extra-galactic emission, together with local and disk absorption.
Proceedings ArticleDOI
50–500 MeV γ‐ray emission in the early phase of SN1987A

TL;DR: In this article, a 3σ upper bound to the steady γ-ray flux of 7×10−4 ph cm−2 s−1 in the 50−500 MeV range was derived.
Journal ArticleDOI
Rosat wide field camera data and the temperature of the interstellar medium
TL;DR: In this article, the shadowing effects of the molecular clouds in the nearby interstellar medium on the soft x-ray background was investigated, using ROSAT WFC data in conjunction with previous rocket B and C band surveys.
