0 Assigned ID: 1057 ----- Attempting Submission 1 (Fri Apr 10 23:39:49 GMT 2015) ----- I have incorporated additional suggestions from my contact scientist. Specifically, I am now using the WFC3-IR-DITHER-BOX-MIN pattern for all WFC3-IR patterns, adding 1 extra exposure (same exposure requirements) to maintain the 5 exposure total for Visits 1, 6, 8 and 10. I have also added ORIENT constraints to Visits 2 and 6, as also suggested. -271342703 ----- Attempting Submission 1 (Tue Jul 21 04:40:45 GMT 2015) ----- HST Phase II Proposal 14068 (APT_proposal_phaseII.apt) successfully submitted.

Receipt: # 14068-3 ----- Attempting Submission 4 (Fri Dec 04 00:55:54 GMT 2015) ----- Resolving the Nuclear Regions of Confirmed Offset AGN We propose HST observations of 10 SDSS galaxies that host X-ray detected active galactic nuclei (AGN) that are significantly spatially offset from the SDSS galaxy nucleus. Since the off-nuclear nature of an AGN can only result from a galaxy merger, these systems are confirmed mergers hosting AGN and give us the unique opportunity to study the connection between galaxy mergers and supermassive black hole (SMBH) growth. However, the resolution of the SDSS is insufficient to resolve the nuclear regions of these mergers, and the combined resolution, sensitivity and multi-band capabilities of HST are now necessary to utilize this sample for studies of galaxy and SMBH co-evolution. By also developing a carefully defined control sample from archival data, our proposed multi-band HST/WFC3 observations will permit us to measure the star-formation rates in the nuclear regions, facilitating a comparison between the triggering of AGN and star-formation in galaxy mergers and an investigation into the role mergers play in the co-evolution of galaxies and SMBHs. By resolving the stellar cores associated with the merging galaxies, we can determine the preference of major versus minor mergers in the triggering of AGN. This study can only be accomplished with HST because 1) the resolution of HST is necessary to resolve the nuclear regions of these merging systems; 2) the sensitivity of HST is necessary to detect the stellar cores if the merger is of a minor classification; and 3) the multi-band imaging is necessary to estimate star-formation rates. Our proposed HST observations will reveal the nature of the nuclear regions of galaxy mergers hosting an AGN. The resolution of HST/WFC3 will easily permit the isolation of both stellar nuclei, and the requested exposures will be deep enough to detect the minor nucleus down to a conservatively low depth. Furthermore, the requested multi-band imaging will allow for a detection of any recent star formation associated with the merger. Camera and Filter Choice: The WFC3 camera in IR and UVIS modes is our instrument of choice as it will enable us to cover the entire wavelength range needed with the highest sensitivity and finest pixel scale. To estimate star-formation rates, we will need multiple filters in order to disentangle, both spectrally and spatially, variations in stellar populations. These requirements will ensure that we can achieve our science goals. In the blue we choose F438W (B) to avoid contamination from Hbeta emission, while in the red we choose F814W (broad I) because of its high throughput and to avoid contamination from emission lines such as [OIII]5007. In the near-infrared, we request F160W (broad H), which will also be optimal for detecting stellar cores. Observational Plan: Using the WFC3 IR and UVIS Exposure Time Calculators, we estimated our science exposure times with the goals of detecting stellar nuclei at IR wavelengths and measuring reliable stellar population magnitudes in all three bands. We request one orbit (54 min) per target, which will provide the exposure times needed to reveal faint secondary nuclei and get the multi-band imaging for stellar population modeling. Consequently, we request 10 orbits of HST observations for our 10 targets. For the IR band (F160W): the exposure time is based on (1) the assumption that the brighter stellar nucleus is two magni- tudes fainter than the total host galaxy; (2) the assumption that the mass ratio, which is unknown, could be as small as 500:1 for the 7 brightest targets (see Figure 3) and as small as 100:1 for the 3 faintest target; and (3) the requirement that each stellar nucleus be detected at a signal-to-noise ratio~20. For the UVIS bands (F438W and F814W): the exposure times are based on the requirement that features 10 times fainter than the integrated galaxy magnitude be detected at S/N~20. The exposure times will be 3x350 sec for F438W, 3x300 sec for F814W, and 4x30 sec for F160W. For each target, there will be 16.5 min of overhead (6 min for guide-star acquisition, 7 min for readout, 2.5 min for dithering, and 1 min to change from IR to UVIS) and the total time spent on science exposures and overhead is 54 min. In the UVIS, we will use a three-point dither pattern to facilitate cosmic-ray and hot-pixel removal. In the IR, we will use the WFC3-IR-DITHER-BOX in order to properly sample the PSF. We will use subarrays (1kx1k for UVIS and IRSUB512 for IR) to avoid buffer dumps, and our readout mode (STEP25 with NSAMP=6) will prevent saturation.
