The paper describing the EXTraS project is in press in Astronomy & Astrophysics. We give details on the algorithms that were designed and implemented to perform all the steps of our EPIC data analysis; we describe our results and products and give information about their basic statistical properties and advice on their usage. The EXTraS project paper is available here on arXiv.
A new EXTraS paper, "Supergiant Fast X-ray Transients uncovered by the EXTraS project: flares reveal the development of magnetospheric instability in accreting neutron stars", has been accepted for publication on the Monthly Notices of the Royal Astronomical Society. The paper is available on ArXiv and directly from the journal. The Bayesian blocks light curves produced by EXTraS provide a new tool for a systematic characterisation of flares from the sub-class of high mass X-ray binaries called Supergiant Fast X-ray Transients. You can read the news on Media INAF (in Italian).
A new exciting result from EXTraS: a mysterious X-ray flare with a duration of 300s from the center of the globular cluster NGC 6540. During the flare the X-ray luminosity increased by more than a factor 40 with a total emitted energy of 1036erg.
The paper reporting the discovery has been published on the journal Astronomy&Astrophysics. You can read it here, on arXiv or here, on A&A.

During a EXTraS workshop, highschool students discover a mysterious X-ray flare. The discovery led to a publication on the journal Astronomy&Astrophysics that you can read here, on arXiv or here, on A&A.

 

This finding produced a broad echo in the media: you can read more on the journal Nature and on the European Commission websites. You might also want to read the ESA press release (in English) or the news on Media INAF (in Italian).
A new EXTraS paper, "Discovery of periodic dips in the brightest hard X-ray source of M31 with EXTraS", has been accepted for publication on Astrophysical Journal. The paper is available on ArXiv. Starting from EXTraS results on aperiodic variability, publicly available through our archive, the brightest X-ray source in the Andromeda galaxy has revealed its true nature: periodic dips in its light curve point to a LMXB system.
