X-ray emission from the microquasar S26 observed by XMM-Newton

Romero, G. E.; Rizzo, F. N.; Sotomayor Checa, P.

S26 is the microquasar with the most powerful jets observed in accreting stellar sources. The estimated kinetic power for its jets is of the order of the bolometric luminosity of some ultraluminous X-ray sources. If this power is coupled to the matter accretion onto the compact object, then S26 must be a super-accreting binary, similar to the gala…

Observaciones del remanente de supernova G296.5+10.0 con el satélite XMM-Newton

Combi, J. A.; Eppens, L. K.; Reynoso, E. M.

G296.5+10.0 is a 90' × 65'-size supernova remnant (SNR) that displays a bilateral distribution in the radio band with the symmetry axis perpendicular to the Galactic Plane. The remnant shows two emission peaks at the South-East and South-West of the radio shell. In addition, the EXOSAT instrument detected an extended X-ray plasma with an axisymmet…
