The Peer REview for Publication and Accreditation of Research Data in the Earth sciences (PREPARDE) project is a JISC and NERC funded project which aims to investigate the policies and procedures required for the formal publication of research data, ranging from ingestion into a data repository, through to formal publication in a data journal. It also(More)
Context. Recent results have revised upwards the total X-ray background (XRB) intensity below ∼10 keV, therefore an accurate determination of the source counts is needed. There are also contradicting results on the clustering of X-ray selected sources. Aims. We have studied the X-ray source counts in four energy bands soft (0.5-2 keV), hard (2-10 keV), XID(More)
GRB 031203 was observed by XMM-Newton twice, first with an observation beginning 6 hours after the burst, and again after 3 days. The afterglow had average 0.2–10.0 keV fluxes for the first and second observations of 4.2 ± 0.1 × 10 −13 and 1.8 ± 0.1 × 10 −13 erg cm −2 s −1 respectively, decaying very slowly according to a power-law with an index of −0.55 ±(More)
We introduce a general range of science drivers for using the Virtual Observatory (VO) and identify some common aspects to these as well as the advantages of VO data access. We then illustrate the use of existing VO tools to tackle multi wavelength science problems. We demonstrate the ease of multi mission data access using the VOExplorer resource browser,(More)
The spectrum of the afterglow of GRB 020322 is the highest-quality X-ray spectrum of a GRB afterglow available to date. It was detected by XMM-Newton in an observation starting fifteen hours after the GRB with a mean 0.2–10.0 keV observed flux of 3.5 ± 0.2 × 10 −13 erg cm −2 s −1 , making it the brightest X-ray afterglow observed so far with XMM-Newton.

The availability of workflows for data publishing could have an enormous impact on researchers, research practices and publishing paradigms, as well as on funding strategies and career and research evaluations. We present the generic components of such workflows to provide a reference model for these stakeholders. The RDA-WDS Data Publishing Workflows group(More)
We present optical and X-ray data for a sample of serendipitous XMM-Newton sources that are selected to have 0.5-2 keV vs 2-4.5 keV X-ray hardness ratios which are harder than the X-ray background. The sources have 2-4.5 keV X-ray flux ≥ 10 −14 erg cm −2 s −1 , and in this paper we examine a subsample of 42 optically bright (r < 21) sources; this subsample(More)
