The XMM-Newton Slew view of IGRJ17361-4441: a transient in the globular cluster NGC 6388

open access: yes, 2012
IGRJ17361-4441 is a hard transient recently observed by the INTEGRAL satellite. The source, close to the center of gravity of the globular cluster NGC 6388, quickly became the target of follow-up observations conducted by the Chandra, Swift/XRT and RXTE ...

Testing general relativity during the cruise phase of the BepiColombo mission to Mercury [PDF]

open access: yes, 2015
General relativity (GR) predicts that photons are delayed and deflected by the space curvature produced by any mass. The Post-Newtonian (PN) parameter controlling the curvature induced by a gravitational field is γ, with bending and delay effects ...

Optical identification of X-ray source 1RXS J180431.1-273932 as a magnetic cataclysmic variable

open access: yes, 2012
The X-ray source 1RXS J180431.1-273932 has been proposed as a new member of the symbiotic X-ray binary (SyXB) class of systems, which are composed of a late-type giant that loses matter to an extremely compact object, most likely a neutron star.
