PI: Dr. Andrew Goulding Princeton University Y CoI: Prof. Jenny Emma Greene Princeton University N CoI: Dr. Ai-Lei Sun Princeton University N CoI: Aida Behmard Princeton University N CoI: Kristina Pardo Princeton University N ------------------------------------------------------------------------------------ Abstract The impact of active galactic nuclei on gas dynamics and star formation holds immense implications for galaxy formation models. We propose high spatial resolution HST imaging observations of SDSS J1000+1242 and SDSS J1010+1413, two luminous obscured AGN that seemingly host powerful galaxy-scale outflows indicative of on-going radiatively-driven feedback. Based on our previous long-slit spectroscopy with Magellan IMACS, the high velocity (~1000km/s) outflows in these objects are extended on 5-10 kpc scales, and hence, are capable of strong interactions with the host galaxy. Analogous to SDSS J1356+1026, which we have previously confirmed to have spatially resolved hot X-ray emitting gas regions coincident with [OIII] emission, both our targets likely host ionized gas super-bubbles. Our proposed observations will provide morphologies of the ionized gas outflows seen in [OIII] emission, as well as measurements of the scattered light fraction that provides crucial information for determining the total gas mass and energetics of the outflows. When combined with previous multi-wavelength data, these observations will allow a complete multi-phase, multi-scale investigation of AGN feedback, and the ability to test the coupling of outflowing material and the central AGN. ------------------------------------------------------------------------------------ Observations Description ------------------------ Here we propose 2 orbits of Hubble Space Telescope imaging of SDSSJ1000+1242 and SDSSJ1010+1413, two z=0.1-0.2 extremely luminous AGN outflow candidates, to probe fine morphological details in outflow features, such as ionized gas superbubbles, and clumps in both ionized gas and scattered light. Only HST can provide sufficiently high resolution imaging to constrain the physics of gas outflows in the efforts of shedding light on outflow origins and effects. To achieve our primary goals, we must: (1) detect the [OIII] emission out to 10 kpc with SNR > 8 per resolution element, and (2) map the stellar light distribution. The exposure times for each filter are as follows: 1. UVIS On-band: To capture the [OIII] emission line, we use the FQ575N band for target SDSS J1000+1242 (z = 0.1481) and the F621M band for SDSS J1010+1413 14730( 5) - 18-Jul-2016 15:42:04 - [ 2] (z = 0.1993). We will use exposure times of 1520 sec and 1380 sec for the two targets, respectively. These observations will achieve S/N=8 per resolution element in the final reconstructed line image. 2. UVIS Off-band: To subtract the continuum from the line-band, we need to measure the continuum level using the off-bands F621M (J1000+1242) and F689M (J1010+1413). To achieve a SNR 6 and 11 for optimum continumm subtraction, we request exposure times of 480 and 650 sec, respectively. 3. IR F160W: This band allows us to map the stellar continuum with high fidelity and no line contamination. We can achieve a SNR of 8 and 6 for SDSS J1000+1242 and SDSS J1010+1413, respectively, for the extended features with 4x24 = 96 sec exposure times. To facilitate cosmic-ray and hot-pixel removal in the UVIS bands, we will use a two point dither for the FQ575N band with the quad array, and for the F621M and F689M bandsm we will use a three-point dither pattern using subarrays (1k x 1k UVIS2-C1K1C-SUB) to avoid buffer dumps, shorten read-out times, and reduce the CTE-losses. In the NIR, we will use the WFC3-IR-DITHER-BOX with a 4-point dither sequence in order to properly sample the PSF. We will use STEP25 with NSAMP=5 to maximize our dynamic range. A subarray configuration of IRSUB512 will also be used to reduce read-out times. Due to our efficient use of sub-arrays, we can perform all three band observations into a single orbit of 54 min for each target, and we need not worry about buffer dumps. Our exposure time calculations include 18 min for overheads (6 min for guide-star acquisition, 4.2 min for dithering, 1.5 min for filter change, 5.6 min for readout, 1 min to change from UVIS to IR). ------------------------------------------------------------------------------------ 14730( 5) -
