Recent HST and Swift observations found the broadband spectral energy distribution was well described by an irradiated accretion disc plus a stellar population. However, degeneracies in the models resulted in two acceptable solutions with dramatically different parameter values. We request two observations to be performed with XMM-Newton and the HST at different X-ray luminosities in order to break these model degeneracies using the variability of the disc emission. With these two 5 orbit observations we will be able to determine the nature of the environment around the black hole, test formation theories for HLX-1, and rule out beaming as the origin of the extreme luminosities. ------------------------------------------------------------------------------------ Observations Description ------------------------ We have been awarded 10 orbits of HST time with the ACS/SBC, WFC3/UVIS, and WFC3/IR cameras. We will observe the candidate intermediate mass black hole HLX-1 in the galaxy ESO 243-49 with simultaneous X-ray observations to be performed with the XMM-Newton telescope. We will split our orbits as such: 5 orbits during the mid-luminosity X-ray state and 5 orbits during the low-luminosity X-ray state. Real Time Justification ----------------------- We request that our HST and XMM-Newton observations be peformed as close together as possible (preferably within +/- 2 days). Calibration Justification ------------------------- 12979( 3) - 26-Sep-2012 18:53:48 - [ 2] Additional Comments ------------------- During a previous set of HST observations of this source with a similar instrument setup, we were advised that there were issues with suitable guide stars in the field for both the ACS/SBC and WFC3/UVIS/IR cameras. To avoid this problem we assigned the ACS/SBC exposure to a separate visit that was performed 10 days apart from the WFC3 exposures. Our previous observation was triggered at short notice following an X-ray outburst. The new observations in this program will not be triggered, but will instead be scheduled during specific time windows when the source is expected to be in the mid and low luminosity X-ray states. We have separated our ACS/SBC and WFC3 exposures in a similar way as previously in order to maximise schedulability, but we request that if possible they be performed within +/- 2 days of each other (i.e. +/-2 days between visit 1 and visit 2, and +/- 2 days between visit 3 and visit 4). If this is not feasible, for example due to a lack of guide stars, please let us know so we can investigate alternative possibilities. ------------------------------------------------------------------------------------ 12979( 3) - 26-Sep-2012 18:53:48 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 HLX-1 STELLAR CLUSTER, RA=01H10M28.3000S +/- 0.3", J2000 Z = V = 23.83 +/- 0.08 far-UV=24.11+/-0.05, ACCRETION DISK, STAR DEC=-46D04'22.30" +/- 0.3" 0.0223 H=24.4+/-0.3 FORMING REGION Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 12979( 3) - 26-Sep-2012 18:53:48 - [ 4] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 1 Primary_Pattern Secondary_Pattern Pattern_Type ACS-SBC-DITHER-BOX Pattern_Purpose DITHER Number_Of_Points 4 Point_Spacing 0.179 Line_Spacing 0.116 Coordinate_Frame POS-TARG Pattern_Orient 20.02 Angle_Between_Sides 63.65 Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 4 Primary_Pattern Secondary_Pattern Pattern_Type WFC3-IR-DITHER-LINE-3PT Pattern_Purpose DITHER Number_Of_Points 3 Point_Spacing 0.605 Line_Spacing Coordinate_Frame POS-TARG Pattern_Orient 41.788 Angle_Between_Sides Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 5 Primary_Pattern Secondary_Pattern Pattern_Type WFC3-UVIS-DITHER-LINE-3PT Pattern_Purpose DITHER Number_Of_Points 3 Point_Spacing 0.135 Line_Spacing Coordinate_Frame POS-TARG Pattern_Orient 46.84 Angle_Between_Sides Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ 12979( 3) - 26-Sep-2012 18:53:48 - [ 5] Visit: 01 Visit Requirements: SCHED 100%; BETWEEN 15-NOV-2012:00:00:00 AND 15-DEC-2012:00:00:00; GROUP 01, 02 WITHIN 2D On Hold Comments: Additional Comments: First far-UV exposure with the ACS/SBV during the mid-luminosity state.
