We present the image and catalogue of the 14.3 μm shallow survey of 0.55 square degrees in the region of the Lockman Hole (105203+572146, J2000) with the Infrared Space Observatory (ISO). The data have been analyzed with the recent algorithm by Lari et al. (2001) conceived to exploit ISO data in an optimal way, especially in the case of shallow surveys with low redundancy. Photometry has been a...

We have identified a likely radio counterpart to the low-mass X-ray binary MXB 1730−335 (the Rapid Burster). The counterpart has shown 8.4 GHz radio on/off behavior correlated with the X-ray on/off behavior as observed by the RXTE/ASM during six VLA observations. The probability of an unrelated, randomly varying background source duplicating this behavior is 1–3% depending on the correlation ti...

We have identiÐed a likely radio counterpart to the low-mass X-ray binary MXB 1730[335 (the Rapid Burster). The counterpart has shown 8.4 GHz radio on/o† behavior correlated with the X-ray on/o† behavior as observed by the RXT E/ASM during six VLA observations.

Based on observations with the X-ray observatories Chandra and XMM-Newton we present results from a detailed spectro-imaging and timing analysis of the central compact X-ray source RX J0822-4300 in the supernova remnant Puppis−A. The superior angular resolution of Chandra allows for the first time to pinpoint the point source nature of this object down to 0.59 ± 0.01 arcsec (FWHM) and to determ...

We observed the “micro-quasar” GRS 1758–258 four times with Chandra. Two HRC-I observations were made in 2000 SeptemberOctober spanning an intermediate-to-hard spectral transition (identified with RXTE ). Another HRC-I and an ACIS/HETGS observation were made in 2001 March following a hard-to-soft transition to a very low flux state. The accurate position (J2000) of the X-ray source is RA = 18 0...

The First Look Survey (FLS) is the first scientific product to emerge from the Spitzer Space Telescope. A small region of this field (the verification strip) has been imaged very deeply, permitting the detection of cosmologically distant sources. We present Westerbork Synthesis Radio Telescope (WSRT) observations of this region, encompassing a ∼ 1 sq. deg field, centred on the verification stri...

The HETE-2 FREGATE and WXM instruments detected a short, hard GRB at 00:26:18.72 UT on 31 May 2002. A preliminary localization was reported as a GCN Position Notice 88 min after the burst, and a refined localization was disseminated 123 minutes later. An IPN local-ization of the burst was reported 18 hours after the GRB, and a refined IPN localization was disseminated ≈5 days after the burst. T...

We present a 40GHz (7.5 mm) raster scan image of a 3.6 • × 2 • region centered on the low redshift (z = 0.055) cluster of galaxies Abell 3667. The cluster was observed during the Antarctic winter of 1999 using the Corona instrument (15.7 ′ FWHM beam) on the Viper Telescope at the South Pole. The Corona image of A3667 is one of the first direct (i.e. rather than interferometer) thermal Sunyaev-Z...

State of the art challenges in sustainable management of water resources have created demand for integrated, flexible and easy to use hydrological models which are able to simulate the quantitative and qualitative aspects of the hydrological cycle with a sufficient degree of certainty. Existing models which have been developed to fit these needs are often constrained to specific scales or purpo...

The Combined EIS-NVSS Survey Of Radio Sources (CENSORS) is a 1.4 GHz radio survey selected from the NRAO VLA Sky Survey (NVSS) and complete to a flux-density of 7.2 mJy. It targets the ESO Imaging Survey (EIS) Patch D, which is a 3 by 2 square degree field centred on 09 51 36.0 −21 00 00 (J2000). This paper presents the results of spectroscopic observations of 143 of the 150 CENSORS sources. Th...
