The quiescent state of the neutron-star X-ray transient GRS 1747-312 in the globular cluster Terzan 6
TL;DR: In this article, the authors studied the transient neutron-star low-mass X-ray binary GRS(1747−312) in its quiescent state after its outburst in August 2004, using an archival XMM-Newton observation.
Multistate observations of the Galactic black hole XTE J1752-223: evidence for an intermediate black hole spin
Rubens Reis,Jon M. Miller,A. C. Fabian,Edward M. Cackett,Dipankar Maitra,Christopher S. Reynolds,Michael P. Rupen,Danny Steeghs,Rudy Wijnands +8 more
TL;DR: In this paper, the authors used a fully relativistic line function in which the black hole spin parameter is a variable, and formally constrained the spin parameter to be 0.52 ± 0.11(1σ ).
A cooling neutron star crust after recurrent outbursts : modelling the accretion outburst history of Aql X-1
TL;DR: In this article, the authors track the thermal evolution of the neutron star in Aql X-1 over the full accretion outburst history from 1996 until 2015, and they find that the envelope composition and shallow heating parameters are allowed to change between outbursts.
Unveiling the hard X-ray spectrum from the ‘burst-only’ source SAX J1753.5-2349 in outburst
M. Del Santo,Lara Sidoli,P. Romano,Angela Bazzano,Rudy Wijnands,Nathalie Degenaar,Sandro Mereghetti +6 more
TL;DR: In this article, the authors presented the first highenergy emission study (above 10 keV) of a so-called burst-only source, SAX J1753.5−2349 was observed for the first time in outburst.
New methods to constrain the radio transient rate: results from a survey of four fields with LOFAR
D. Carbone,A. J. van der Horst,Ralph A. M. J. Wijers,John D. Swinbank,Antonia Rowlinson,J. W. Broderick,Y. Cendes,Adam Stewart,Martin Bell,Rene P. Breton,Stephane Corbel,Jochen Eislöffel,Rob Fender,Jean-Mathias Grießmeier,Jason W. T. Hessels,Peter G. Jonker,Michael Kramer,C.J. Law,James Miller-Jones,M. Pietka,L. H. A. Scheers,Benjamin Stappers,J. van Leeuwen,Rudy Wijnands,Michael W. Wise,P. Zarka +25 more
TL;DR: It is shown that low-frequency radio surveys are more sensitive to steep-spectrum coherent transient sources than GHz radio surveys, and upper limits for the transient surface density for transients of different time-scales are calculated.
