Evolution of the X-ray jets from 4U 1755-33. Kaaret P., Corbel S., Tomsick J.A., Lazendic J., Tzioumis A.K., Butt Y., Wijnands R. <Astrophys. J., 641, 410-417 (2006)> =2006ApJ...641..410K
ADC_Keywords: X-ray sources ; Binaries, X-ray Keywords: black hole physics - stars: individual (4U 1755-33) - stars: winds, outflows - X-rays: binaries Abstract: We report on new X-ray observations of the large-scale jets recently discovered in X-rays from the black hole candidate 4U 1755-33. Our observations in 2004 show that the jets found in 2001 are still present in X-rays. However, sensitive radio observations in 2004 failed to detect the jets. Description: We observed 4U 1755-33 using XMM-Newton beginning on 2004 September 18 (observation B). We also analyzed an archival observation obtained by Angelini & White (2003ApJ...586L..71A) beginning on 2001 March 8 (observation A). On 2004 April 27, we obtained continuum radio observations of 4U 1755-33 using the Australia Telescope Compact Array (ATCA) located in Narrabri, New South Wales, Australia. To determine if the features found in the XMM-Newton X-ray image are point sources or truly diffuse emission, we analyzed two Chandra observations obtained of the same field, on 2003 September 25 and on 2004 June 25.
