PI: Dr. Jacobo Ebrero ESA-European Space Astronomy Centre Y CoI: Dr. Jelle Kaastra Space Research Organization Netherlands N CoI: Dr. Gerard A. Kriss Space Telescope Science Institute N ------------------------------------------------------------------------------------ Abstract AGN mass outflows inject enormous amounts of matter and energy into the interstellar medium of the host galaxy. Their location, structure, and importance as contributors to cosmic feedback processes are not yet fully understood. We propose to observe the Seyfert 1 galaxy NGC 985 with XMM-Newton for 240 ks using RGS as the prime instrument in order to accurately characterize the different ionized phases and kinematic components of the warm absorber. Together with HST/COS we will study the connection between the X-ray and UV absorbers and put stringent limits on the location of these winds in the context of the unification model of AGN. ------------------------------------------------------------------------------------ Observations Description ------------------------ Our program consists of two 5-orbit visits simultaneous with two XMM-Newton observations. The second visit is nominally 12 days after the first XMM observation. For a median historical continuum flux of 2e-14 erg cm^{-2} s^{-1} A^{-1} (Dunn et al. 2006, PASP, 118, 572) the on-line COS Exposure Time Calculator requires 2700 s in G130M/1309 to cover Ly-alpha and N V, 3200 s with G160M/1600 for Si IV and C IV, and 5700 s with G140L/1280 to cover Ly-beta and O VI. In a single 5-orbit visit we can achieve the requisite exposure times with all three gratings. Each visit in our program will consist of multiple spectra for each grating. Since NGC 985 is faint enough, and all historical flux levels are more than a factor of two below safe limits, we will use an imaging target acquisition for each visit. For G130M, we will use three central wavelength settings that avoid placing the gap between segments A and B near the intrinsic absorption complex in NGC 985. At the same time, each central wavelength setting will obtain coverage of the segment gap in the other spectra. For each central wavelength setting, we will use different FP-POS settings, giving us a total of 4 independent grating settings with G130M that will allow us to eliminate all detector features and maximize our S/N in the merged spectrum. For G160M, we will again have 5 independent grating settings, but spread among four central wavelength settings in order to place the gap between the segments in the red wing of C IV as far from line center as possible, so that detector edge effects do not affect the intrinsic absorption lines in the blue wing of C IV. To allow for a broad range of variability in NGC 985, we have chosen BUFFER 13812( 2) - 11-Jul-2014 15:34:28 - [ 2] TIMES significantly shorter than the 2/3 factor recommended in the ETC. We have also chosen the BUFFER TIMES to be integer multiples of (exposure time - 110 s) to minimze the overheads due to buffer readouts between successive exspoures. These observations pose no bright object concerns. All historical flux levels for NGC 985 lie well below the bright object limits for COS. Since Mrk 335 has been observed successfully before with STIS, there are also no surrounding field objects that are too bright. This is confirmed by the BOT tool for GALEX in APT. The violation indicated in the GSC-II BOT check is for the extended host galaxy. ------------------------------------------------------------------------------------ 13812( 2) - 11-Jul-2014 15:34:28 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 NGC-985 GALAXY, SEYFERT RA=02H34M37.8820S +/- 0.43", J2000 V = 14.28 +/- 0.5 1.47e-14 at 1413 A DEC=-08D47'17.02" +/- 0.43" Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the SIMBAD database. ------------------------------------------------------------------------------------------------------------------------------------ 13812( 2) - 11-Jul-2014 15:34:28 - [ 4] Visit: 01 Visit Requirements: SCHED 100% On Hold Comments: Additional Comments: Simultaneous with first XMM-Newton visit.
