We will study the connection between the X-ray and UV absorber, mapping the ionization structure, kinematic behavior and elemental abundances. Finally we will quantify the AGN feedback by directly measuring the metal enrichment by C, N, O, and Fe and the kinetic luminosity of the outflow. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will observe I Zw1 with HST-COS for 8 orbits organized into 2 identical visits. Both visits should be within days of each other, and coordinated with an approved XMM-Newton observation of I Zw 1. This will allow us to study the combined UV-X-ray properties of the outflowing gas, not not only in the strong Ly alpha and CIV troughs, but also among others such as N V (1238, 1242 A) and Si IV(1393, 1402 A) transitions. A large number of ions will put more stringent constraints on the ionization parameter of the multi-kinetic components of the UV gas. The sensitivity of COS will also allow us to study metastable levels such as CIII* at =1176 A. These excited levels have a similar ionization of the UVX-ray absorbers and provide valuable density (and therefore distance) diagnostic measurements. We will reanalyze the FUSE data with updated methods for an estimate of the CIII ground level transition (977 A). Even a non-detection of CIII will put useful upper limit on the gas density. I Zw1 has been recently observed (Nov 2012) using the G130M grating of COS for a total of only 1.8 ks. A preliminary look at the data highlights the broad Ly alpha trough, outflowing at 2000 km s^{-1}, tentatively confirming the existence of the long-lived UV-X-ray outflow, which possibly varies only in ionization state. CIII* 1176 is tentatively identified, possibly outflowing, but the present quality of the data makes it difficult to disentagle it from other intrinsic and Galactic lines. We will therefore observe I Zw 1 using both the G130M grating for ~6 ks and the G160M grating for ~11 ks in order to reach a S/N of 20 in the continuum. This will assure a S/N=10 in the bottom of the UV 13811( 2) - 18-Jul-2014 14:05:04 - [ 2] absorption troughs, which will enable us to determine the covering fraction of the absorbing gas to an accuracy of 10%. The enhanced exposure time for G160M relative to G130M is needed to compensate for its lower sensitivity. We based our ETC calculations using the fluxes of the COS data already acquired, considering a flux of 1e-14 erg cm^{-2} s^{-1} A^{-1} at 1440 A. We use multiple central wavelength settings and multiple FP-POS positions to bridge the gap between detector segments, and to avoid detector and flat-field artifacts. Central wavelengths and FP-POS positiopns were chosen to avoid placing the gap in wavelength regions corresponding to features of interest, as described in our comments for each exposure. To allow for source variability, we have chosen BUFFER 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 I Zw 1 lie below the bright object limits for COS (see Dunn et al. 2006, PASP, 118, 572). Since I Zw 1 has been observed successfully before, there are also no surrounding field objects that are too bright. This is confirmed by the BOT tool for GALEX in APT. ------------------------------------------------------------------------------------ 13811( 2) - 18-Jul-2014 14:05:04 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 IZW1 GALAXY, ACCRETION DISK, RA=00H53M34.9300S +/- 0.2", J2000 Z = V = 14.1 +/- 0.1 1.0e-14 at 1440 A BLR, NLR, NUCLEUS, DEC=+12D41'36.19" +/- 0.2" 0.0589 SEYFERT Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 13811( 2) - 18-Jul-2014 14:05:04 - [ 4] Visit: 01 Visit Requirements: SCHED 100% On Hold Comments: Additional Comments: Visit 1 should be scheduled within days of Visit 2.
