And yet, the complex interplay between outflows and their host galaxy remains largely unconstrained at relevant physical scales. The lack of direct observational measurements of small-scale energetic properties of the multiphase ISM is a big hurdle for constraining feedback prescriptions for the next generation cosmological models. Since July, new JWST results shed light on the dust-obscured energy sources in nearby (U)LIRGs, prompting the question of what the total contribution to the energy budget from shocks due to said sources across entire galaxies. Here we propose deep narrowband imaging of key near-infrared diagnostic lines for a pilot sample of 3 galaxy mergers with newly published JWST results that represent the best laboratories to explore the starburst-AGN-shocks connection in the nearby universe. Resolving the shocked gas in ionized outflows with wide-field, 17285( 2) - 19-Dec-2022 20:39:38 - [ 2] high-resolution WFC3 images, this study aims to address: 1. How AGN and stellar feedback drive shocks across the ISM; and 2. How winds impact star formation and chemical enrichment within the host galaxy. Our proposed study will tackle complex feedback physics in high gas content environments, commonplace among star-forming galaxies near the cosmic noon. Leveraging a rich ancillary data set including ground-based optical and newly analyzed JWST infrared imaging and integral-field observaions, the new HST observations will yield unique insights into the role of feedback in galaxy evolution and establish the significance of near-infrared diagnostics in the early JWST era. ------------------------------------------------------------------------------------ Observations Description ------------------------ WFC3 provides a set of narrowband filters in the J-band, unavailable to JWST/NIRCam, that is uniquely suited to image [Fe ii] (1.26um) and Pab (1.28um) among nearby objects. We will use a combination of narrow- (F126N, F128N, F130N, F132N) and wide-band (F110W and F160W) filters, since continuum subtraction works better and more efficiently given the color correction as determined from two wide-band images than that from an off-line narrowband filter. We estimated exposure times using ancillary groundbased APO/TripleSpec spectra of our targets, where available, centered on the body of the galaxy with extraction aperture width of 7.5". We estimate that the emission line at the 10 kpc outskirts would be 2 orders of magnitude fainter based on the dynamic range in typical outflows. With the WFC3/IR ETC aiming for a target SNR of 10 per resolution element (2 px x 2 px), we calculate the exposure time needed to reach our S/N limit. We request 3 exposures / dithers per filter for robust cosmic-ray removal. Two of our 3 targets have one narrowband or wideband images available in the archive; we have checked and found that the depth of the archival data sufficient for our study. Therefore, the corresponding narrowband or wideband data will not be requested; instead, we will incorporate the archival data into our analysis to enhance the legacy value of HST data sets. Overhead estimates include setup + filter changes + readout (1 min per each of 3 exposures), dithering (1-6 min per offset), and guide star (re)acquisition (6 min at the first orbit, 5 min after in non-CVZ). These calculations amount to 1-2 orbits being requested for each source. Accounting for orbital visibility, we request a total of 4 new orbits for the complete set of narrow- and wide-band images for our pilot sample. ------------------------------------------------------------------------------------ 17285( 2) - 19-Dec-2022 20:39:38 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 NGC-7469 GALAXY, INTERACTING RA=23H03M16.6595S, J2000 V = 12.34 GALAXY, SEYFERT DEC=+08D52'45.94" Reference Frame: Other: SIMBAD Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.
