Two decades of X-ray observations of the isolated neutron star RX J1856.5-3754: detection of thermal and non-thermal hard X-rays and refined spin-down measurement
Davide De Grandis, Michela Rigoselli, Sandro Mereghetti +6
The soft X-ray pulsar RX J1856.5-3754 is the brightest member of a small class of thermally-emitting, radio-silent, isolated neutron stars. Its X-ray spectrum is almost indistingui…
The first 7 months of the 2020 X-ray outburst of the magnetar SGR J1935+2154
Alice Borghese, Francesco Coti Zelati, Gian Luca Israel +10
The magnetar SGR J1935+2154 underwent a new active episode on 2020 April 27-28, when a forest of hundreds of X-ray bursts and a large enhancement of the persistent flux were detect…
X-ray observation of the Roche-lobe filling white dwarf plus hot subdwarf system ZTF J213056.71+442046.5
S. Mereghetti, N. La Palombara, T. Kupfer +9
ZTF J213056.71+442046.5 is the prototype of a small class of recently discovered compact binaries composed of a white dwarf and a hot subdwarf that fills its Roche-lobe. Its orbita…
Recurrent X-ray flares of the black hole candidate in the globular cluster RZ 2109 in NGC 4472
A. Tiengo, P. Esposito, M. Toscani +7
We report on the systematic analysis of the X-ray observations of the ultra-luminous X-ray source XMMU J122939.7+075333 located in the globular cluster RZ 2109 in the Virgo galaxy…
The origin of the unfocused XMM-Newton background, its variability and lessons learned for ATHENA
Fabio Gastaldello, Martino Marelli, Silvano Molendi +7
We analyzed the unexposed to the sky outFOV region of the MOS2 detector on board XMM-Newton covering 15 years of data amounting to 255 Ms. We show convincing evidence that the orig…
IKT16: Discovery of a 22 ms energetic rotation-powered pulsar in the Small Magellanic Cloud
C. Maitra, P. Esposito, A. Tiengo +5
We report here on the discovery with XMM-Newton of pulsations at 22 ms from the central compact source associated with IKT16, a supernova remnant in the Small Magellanic Cloud (SMC…
