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…
Optical counterparts of undetermined type -ray Active Galactic Nuclei with blazar-like Spectral Energy Distributions
G. La Mura, G. Chiaro, S. Ciroi +4
During its first four years of scientific observations, the Fermi Large Area Telescope (Fermi-LAT) detected 3033 -ray sources above a 4 significance level. Although most of t…
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…
Radio-quiet and radio-loud pulsars: similar in Gamma-rays but different in X-rays
M. Marelli, R. P. Mignani, A. De Luca +4
We present new Chandra and XMM-Newton observations of a sample of eight radio-quiet Gamma-ray pulsars detected by the Fermi Large Area Telescope. For all eight pulsars we identify…
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…
