The EXTraS Project: Exploring the X-ray transient and variable sky
A. De Luca, R. Salvaterra, A. Belfiore +29
Temporal variability in flux and spectral shape is ubiquitous in the X-ray sky and carries crucial information about the nature and emission physics of the sources. The EPIC instru…
The Ultraluminous X-ray sources population of the galaxy NGC 7456
F. Pintore, M. Marelli, R. Salvaterra +28
Ultraluminous X-ray sources (ULXs) are a class of accreting compact objects with X-ray luminosities above 1e39 erg/s. The ULX population counts several hundreds objects but only a…
A science gateway for Exploring the X-ray Transient and variable sky using EGI Federated Cloud
Daniele D'Agostino, Luca Roverelli, Gabriele Zereik +7
Modern soft X-ray observatories can yield unique insights into time domain astrophysics, and a huge amount of information is stored - and largely unexploited - in data archives. Li…
A citizen science exploration of the X-ray transient sky using the EXTraS science gateway
Daniele D'Agostino, Duncan Law-Green, Mike Watson +6
Modern soft X-ray observatories can yield unique insights into time domain astrophysics, and a huge amount of information is stored - and largely unexploited - in data archives. Li…
Discovery of a 2.8 s pulsar in a 2 d orbit High-Mass X-ray Binary powering the Ultraluminous X-ray source ULX-7 in M51
G. A. Rodríguez Castillo, G. L. Israel, A. Belfiore +26
We discovered 2.8 s pulsations in the X-ray emission of the ultraluminous X-ray source (ULX) M51 ULX-7 within the UNSEeN project, which was designed to hunt for new pulsating ULXs…
Discovery of periodic dips in the brightest hard X-ray source of M31 with EXTraS
M. Marelli, A. Tiengo, A. De Luca +9
We performed a search for eclipsing and dipping sources in the archive of the EXTraS project - a systematic characterization of the temporal behaviour of XMM-Newton point sources.…
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…
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…
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…
