Discovery of a magnetar candidate X-ray pulsar in the Large Magellanic Cloud
M. Imbrogno, G. L. Israel, G. A. Rodríguez Castillo +11
During a systematic search for new X-ray pulsators in the XMM-Newton archive, we discovered a high amplitude () periodic () modulation in the…
Probing the nature of the low state in the extreme ultraluminous X-ray pulsar NGC 5907 ULX1
F. Fuerst, D. J. Walton, G. L. Israel +13
NGC 5907 ULX1 is the most luminous ultra-luminous X-ray pulsar (ULXP) known to date, reaching luminosities in excess of 1e41 erg/s. The pulsar is known for its fast spin-up during…
Deep X-ray and radio observations of the first outburst of the young magnetar Swift J1818.0-1607
A. Y. Ibrahim, A. Borghese, N. Rea +23
Swift J1818.0-1607 is a radio-loud magnetar with a spin period of 1.36 s and a dipolar magnetic field strength of B~3E14 G, which is very young compared to the Galactic pulsar popu…
EXTraS discovery of two pulsators in the direction of the LMC: a Be/X-ray binary pulsar in the LMC and a candidate double-degenerate polar in the foreground
F. Haberl, G. L. Israel, G. A. Rodriguez Castillo +10
The EXTraS project to explore the X-ray Transient and variable Sky searches for coherent signals in the X-ray archival data of XMM-Newton. XMM-Newton performed more than 400 pointe…
An accreting pulsar with extreme properties drives an ultraluminous x-ray source in NGC 5907
G. L. Israel, A. Belfiore, L. Stella +20
Ultraluminous x-ray sources (ULXs) in nearby galaxies shine brighter than any X-ray source in our Galaxy. ULXs are usually modeled as stellar-mass black holes (BHs) accreting at ve…
Discovery of a 0.42-s pulsar in the ultraluminous X-ray source NGC 7793 P13
G. L. Israel, A. Papitto, P. Esposito +11
NGC 7793 P13 is a variable (luminosity range ~100) ultraluminous X-ray source (ULX) proposed to host a stellar-mass black hole of less than 15 M in a binary system with o…
The discovery, monitoring and environment of SGR J1935+2154
G. L. Israel, P. Esposito, N. Rea +9
We report on the discovery of a new member of the magnetar class, SGR J1935+2154, and on its timing and spectral properties measured by an extensive observational campaign carried…
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…
Periodic signals from the Circinus region: two new cataclysmic variables and the ultraluminous X-ray source candidate GC X-1
P. Esposito, G. L. Israel, D. Milisavljevic +5
The examination of two 2010 Chandra ACIS exposures of the Circinus galaxy resulted in the discovery of two pulsators: CXO J141430.1-651621 and CXOU J141332.9-651756. We also detect…
CXOU J005047.9-731817: a 292-s X-ray binary pulsar in the Small Magellanic Cloud
P. Esposito, G. L. Israel, L. Sidoli +4
We report on the discovery of a transient X-ray pulsars, located in the Small Magellanic Cloud, with a pulse period of 292 s. A series of Chandra pointings fortuitously recorded in…
Discovery of 47-s pulsations in the X-ray source 1RXS J225352.8+624354
P. Esposito, G. L. Israel, L. Sidoli +5
We report on the discovery of pulsations at a period of ~47 s in the persistent X-ray source 1RXS J225352.8+624354 (1RXS J2253) using five Chandra observations performed in 2009. T…
