The Low X-Ray State of LS 5039 / RX J1826.2-1450
A. Martocchia, C. Motch, I. Negueruela
Recent XMM-Newton and Chandra observations of the high mass X-ray binary LS 5039 / RX J1826.2-1450 caught the source in a faint X-ray state. In contrast with previous RXTE observat…
The proper motion of the isolated neutron star RX J1605.3+3249
C. Motch, K. Sekiguchi, F. Haberl +3
We obtained deep optical imaging of the thermally emitting X-ray bright and radio-quiet isolated neutron star RX J1605.3+3249 with the Subaru telescope in 1999 and 2003. Together w…
The isolated neutron star X-ray pulsars RX J0420.0-5022 and RX J0806.4-4123: new X-ray and optical observations
F. Haberl, C. Motch, V. E. Zavlin +6
We report on the analysis of new X-ray data obtained with XMM-Newton and Chandra from two ROSAT-discovered X-ray dim isolated neutron stars. RX J0806.4-4123 was observed with XMM-N…
X-ray flares from the ultra-luminous X-ray source in NGC 5408
R. Soria, C. Motch, A. M. Read +1
We have studied an ultra-luminous X-ray source (ULX) in the dwarf galaxy NGC 5408 with a series of XMM-Newton observations, between 2001 July and 2003 January. We find that its X-r…
A variable ultra-luminous X-ray source in the colliding galaxy NGC 7714
Roberto Soria, Christian Motch
We studied the colliding galaxy NGC 7714 with two XMM-Newton observations, six months apart. The galaxy contains two bright X-ray sources: we show that they have different physical…
