A transient ultraluminous X-ray source in NGC 55
A. Robba, C. Pinto, F. Pintore +14
Ultraluminous X-ray sources (ULXs) are a class of accreting compact objects with X-ray luminosities above 10 erg s. The average number of ULXs per galaxy is still not…
Multi-messenger and transient astrophysics with the Cherenkov Telescope Array
Ž. Bošnjak, A. M. Brown, A. Carosi +142
The discovery of gravitational waves, high-energy neutrinos or the very-high-energy counterpart of gamma-ray bursts has revolutionized the high-energy and transient astrophysics co…
The multi-outburst activity of the magnetar in Westerlund I
A. Borghese, N. Rea, R. Turolla +17
After two major outbursts in 2006 and 2011, on 2017 May 16 the magnetar CXOU J164710.2-455216, hosted within the massive star cluster Westerlund I, emitted a short (20 ms) burst, w…
The first orbital period of a very bright and fast Nova in M31: M31N 2013-01b
Martino Marelli, Domitilla De Martino, Sandro Mereghetti +5
We present the first X-ray and UV/optical observations of a very bright and fast nova in the disc of M31, M31N 2013-01b. The nova reached a peak magnitude 15 mag and decayed…
A new Ultraluminous X-ray source in the galaxy NGC 5907
F. Pintore, A. Belfiore, G. Novara +14
We report on the serendipitous discovery of a new transient in NGC 5907, at a peak luminosity of 6.4x10^{39} erg/s. The source was undetected in previous 2012 Chandra observations…
