EXTraS discovery of an 1.2-s X-ray pulsar in M 31
P. Esposito, G. L. Israel, A. Belfiore +13
During a search for coherent signals in the X-ray archival data of XMM-Newton, we discovered a modulation at 1.2 s in 3XMM J004301.4+413017 (3X J0043), a source lying in the direct…
The Outburst Decay of the Low Magnetic Field Magnetar SWIFT J1822.3-1606: Phase-resolved Analysis and Evidence for a Variable Cyclotron Feature
Guillermo A. Rodríguez Castillo, Gian Luca Israel, Andrea Tiengo +12
We study the timing and spectral properties of the low-magnetic field, transient magnetar SWIFT J1822.3-1606 as it approached quiescence. We coherently phase-connect the observatio…
Results from DROXO IV. EXTraS discovery of an X-ray flare from the Class I protostar candidate ISO-Oph 85
Daniele Pizzocaro, Beate Stelzer, Roberta Paladini +15
X-ray emission from Young Stellar Objects (YSOs) is crucial to understand star formation. A very limited amount of X-ray results is available for the protostellar (ClassI) phase. A…
A magnetic diverter for charged particle background rejection in the SIMBOL-X telescope
D. Spiga, V. Fioretti, A. Bulgarelli +6
Minimization of charged particle background in X-ray telescopes is a well known issue. Charged particles (chiefly protons and electrons) naturally present in the cosmic environment…
IKT 16: the first X-ray confirmed composite SNR in the SMC
Chandreyee Maitra, Jean Ballet, Miroslav Filipovic +4
Aims: IKT 16 is an X-ray and radio-faint supernova remnant (SNR) in the Small Magellanic Cloud (SMC). A detailed X-ray study of this SNR with XMM-Newton confirmed the presence of a…
Follow-up observations of X-ray emitting hot subdwarf star: the He-rich sdO BD +37° 1977
N. La Palombara, P. Esposito, S. Mereghetti +2
We report on the results of the first XMM-Newton satellite observation of the luminous and helium-rich O-type subdwarf BD +37° 1977 carried out in April 2014. X-ray emission is det…
The X-ray outburst of the Galactic Centre magnetar SGR J1745-2900 during the first 1.5 year
F. Coti Zelati, N. Rea, A. Papitto +17
In 2013 April a new magnetar, SGR 1745-2900, was discovered as it entered an outburst, at only 2.4 arcsec angular distance from the supermassive black hole at the Centre of the Mil…
The study of neutron star magnetospheres with LOFT
R. P. Mignani, F. Bocchino, N. Bucciantini +24
This is a White Paper in support of the mission concept of the Large Observatory for X-ray Timing (LOFT), proposed as a medium-sized ESA mission. We discuss the potential of LOFT f…
