Following the discovery by Chandra of radio/X-ray jets in five microquasars, it becomes clear that X-ray jets are probably much more common than previously thought, and they offer an exciting new way to probe the physics of relativistic jets from black holes and their feedback on the ISM. The proposed ToO observations are optimized to discover and study (flux evolution, morphology, SED, proper motion, ...) new X-ray jets from microquasars, triggered by their detection as radio lobes. This will have implications not only for the study of jets from Galactic X-ray binaries, but also for our understanding of relativistic jets from active galactic nuclei (AGN). ------------------------------------------------------------------------------------ Observations Description ------------------------ HST observations in the IR will complement the measurements of the extended jets in the radio and X-rays and be used to bridge the gap in the spectral energy distribution. We will use WFC3 with the F160W. The observations will be 1 HST orbit for the first two Chandra observations and 2 HST orbits for the two final observations when we expect the jets to be much fainter and more extended. On each orbit, we will observe with the WFC3/F160W with 2 dither positions. The response for HST is longer than 3 weeks, therefore not constraining for HST. The separation between observations will be approximately by one month, except for the last observation which will 2 months after the third. ------------------------------------------------------------------------------------ 17871( 3) - 12-Nov-2024 14:10:36 - [ 2] TARGET LIST Generic Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Selection Criteria | Flux data No | Name | Description | | ------------------------------------------------------------------------------------------------------------------------------------ 1 XRAY-JETS OTHER: DISCOVERY OF A NEW, V = 20 +/- 1 VARIABLE RADIO SOURCE AT LEAST 2 ARCSEC FROM A KNOWN BLACK HOLE CANDIDATE. Comments: Since the flux information is used to check for over-illumination of sensitive detectors, we give the V-mag for the central black hole. It will be a point source and be significantly brighter than the extended jets that are the science focus of the proposal. In the decaying phases of the outburst, i.e. when the transient radio jets are observed, the black hole should be dimmer than 19th magnitude in V. The extended jet should have a flux around 1E-6 Jy at 1.5 microns over 1.2 arcsecond diameter region and a spectrum with a F_nu index of -0.7 and reddening of A_V = 4.75. ------------------------------------------------------------------------------------------------------------------------------------ 17871( 3) -
