The effects of dust are degenerate with those of the galaxy's star formation history, because stellar populations of different ages can be subject to different levels of attenuation in the presence of patchy dust. We propose to separate the variations of the ultraviolet-to-nearIR (UV-to-NIR) dust attenuation from those of the star formation history in star-forming galaxies, by leveraging the multi-wavelength and high resolution capabilities of HST. We will complement archival HST data with new ACS and WFC3 broad and narrow-band imaging to probe the SEDs of the stars and the hydrogen recombination lines of H-alpha and Pa-beta to model the spatially-resolved stellar populations, gas emission, and dust in five nearby galaxies hosting central starbursts. The five starbursts are selected based on their global far-infrared and UV emission properties, which deviate from those of typical starbursts in the local Universe, making them puzzling outliers. FUV (1600 Angstrom) to NIR (~1.6 micron) SEDs of individual star clusters and HII regions will provide necessary constraints to separate variations of stellar ages in patchy dust from variations of the shape and normalization of the dust attenuation curve. Our study will provide a benchmark for dust attenuation corrections directly applied to UV-to-NIR SEDs. This will remain the only viable option to derive physical parameters for the large high-redshift galaxy surveys produced by the JWST, Roman, Euclid, and ELTs. ------------------------------------------------------------------------------------ Observations Description ------------------------ Target Selection: Our targets are selected to be starbursts with IRX values 2 sigma or more below those of the IRX-beta relation marked by the SB curve and to span a range in beta, to probe the attenuation curve along the locus marked by the SMC curve. We impose a distance limit of 10 Mpc to achieve spatial resolution better than 5 pc with HST. Observational Set--Up and Exposure Times. 17225( 8) - 07-Jun-2024 17:52:52 - [ 2] Instrument/filter combinations are chosen to complete the archival datasets and cover the full FUV-H range for each target. Our template source is a 5000 M_sun, 4 Myr old star cluster with a conservative A_V=1.5~mag (F(1600)=2.5x10-1 ~erg/s/cm^2/AA and Sigma(Pa-beta)=2x10^-16 erg/s/cm^2/arcse$^2 at 4.5 Mpc distance). ACS/SBC 2x2 mosaics in F150LP are planned for NGC4214 and NGC5236 to cover the UV--emitting starburst regions, while one pointing only is required for NGC3351. S/N=5 is expected to be achieved for the above template cluster in 600 s per mosaic tile in NGC4214 and NGC5236 and in 2, 400 s for NGC3351 (located at twice the distance of the other two galaxies). WFC3/UVIS observations for NGC3351 (F218W), NGC4214 and NGC5236 (F275W), and NGC5253 (F657N+F547M) will be obtained with S/N>=10 for our template cluster in 2, 500 s (F218W), 2, 000 s (F275W), 2, 000 s (F657N). WFC3/IR observations will be obtained for NGC5474 in F110W, F128N, F160W, with S/N>=10 in 900 s, 2300 s, and 900 s, respectively. F547M and F110W are observed with S/N>20 to ensure that the subtraction of the stellar continuum from the narrow-band filter does not dominate the noise budget. Each WFC3 exposure is divided into 3-4 dither patterns to remove CRs and fill the chip gap. The WFC3 UV/U and H-alpha exposures include 20 s post--flash. The S/N in the FUV is sufficient to discriminate between individual attenuation slopes to >5 sigma; the combination of SBC/F150LP, WFC3/F218W (or F225W) and F275W separates mean UV slopes from effects of the 2175 A bump to >10 sigma. ------------------------------------------------------------------------------------ 17225( 8) - 07-Jun-2024 17:52:52 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 NGC-3351 GALAXY, SPIRAL, RA=10H43M57.7310S, J2000 V = 11.92 STARBURST DEC=+11D42'13.24" Reference Frame: Other: NED Comments: This object was generated by the targetselector and retrieved from the NED database.
