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.

An exciting result from EXTraS: the extreme ULX in NGC 5907, one of the best intermediate mass black hole candidates, is truly an accreting neutron star. Other properties of this system must also be extreme to sustain its apparent luminosity, 1000 times beyond its Eddington limit.
The paper reporting the discovery has been accepted for publication by the journal Science and is now in press. You can read it here, on arXiv or here, on Science.

Another result from the EXTraS search for X-ray pulsators: an accreting pulsar orbiting a Be star in the Large Magellanic Cloud. In the same direction, pulsations were detected from a likely double-degenerate polar in our Galaxy. The paper reporting this discovery appeared on the journal Astronomy and Astrophysics . You can read it here, on arXiv or here, in A&A.
