Putman Columbia University in the City of New N York ------------------------------------------------------------------------------------ Abstract We propose high spatial resolution optical, UV, and narrowband Ha imaging of 6 nearby pairs of dwarf galaxies with enhanced star formation likely driven by a dwarf-dwarf interaction. Dwarf-dwarf interactions dominate galaxy interactions at all redshifts, making this environment essential to our understanding of galaxy assembly and star formation throughout the universe. However, little is known about how galaxy mergers proceed at low mass. The high resolution observations proposed here will resolve individual star clusters (a goal not currently possible from the ground) to explore the role of tidal interactions in triggering clumpy star formation and in promoting the formation of massive star clusters in low metallicity environments. This mode of cluster formation was likely dominant during early galaxy assembly, and the extent to which star formation is clumped is predicted to play a role in the extent to which feedback impacts the interstellar medium. Our sample of isolated dwarf-dwarf interactions offers the only opportunity for a high resolution view of this mode of cluster formation outside the influence of a massive galaxy host. ------------------------------------------------------------------------------------ Observations Description ------------------------ We aim to obtain WFC3/UVIS broadband optical (F621M and F814W), UV (F336W), and narrowband (F665N) imaging for 6 interacting dwarf pairs to resolve individual star clusters and thus determine accurate ages, masses, and distributions. The medium-band F621M images will be used to subtract the continuum to measure Ha fluxes from the (redshifted) narrowband F665N images, in addition to providing an additional data point on the SED. One WFC3/UVIS field of view can be used to observe both dwarfs simultaneously for 5 of the 6 target pairs, but the remaining pair will require two fields of view. To detect clusters of Mstar ~ 10^4 Msun as old as 100 Myr at the distance of our pairs (20-40 Mpc), we set our sensitivity requirement using the magnitudes predicted for clusters of that mass and age by Starburst99 models. Starburst99 predicts an absolute V band magnitude of -10.5. To achieve S/N ratios of 40-50 15087( 7) - 13-Dec-2018 16:43:51 - [ 2] for this magnitude, the ETC determines that we can reach this level of sensitivity in ~25, 9, 4, and 4 minutes of integration time in the Ha (F665N), U (F336W), mediumband (F621M), and I (F814W) broadband respectively at a distance of 20 Mpc which we then scale to the distances of our dwarf pairs. By combining the narrowband Ha and broadband I observations into one orbit (per individual dwarf or dwarf pair) and by combining the broadband U and mediumband optical observations into a second orbit, we have 10-15 minutes remaining per orbit for overhead (including an estimate of 6 minutes to acquire and an additional 0.5 minutes per dither). To make our program as efficient as possible, we place no constraints on the timing or the roll angle of the observations. These are not coordinated observations. ------------------------------------------------------------------------------------ 15087( 7) - 13-Dec-2018 16:43:51 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 INTERACTING- GALAXY, AMORPHOUS RA=16H47M11.0251S, J2000 V = 17.0 +/- 0.5 GAL-164711+2 IRREGULAR, INTERACTING DEC=+21D05'35.68" 10529 GALAXY, STAR FORMING REGION Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 2 INTERACTING- GALAXY, AMORPHOUS RA=15H29M26.9192S, J2000 V = 16.4 +/- 0.5 GAL-152927+2 IRREGULAR, INTERACTING DEC=+25D59'55.99" 60003 GALAXY, STAR FORMING REGION Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 4 INTERACTING- GALAXY, AMORPHOUS RA=12H25M31.5000S, J2000 V = 16.2 +/- 0.5 GAL-122532+5 IRREGULAR, INTERACTING DEC=+50D19'58.50" 01959 GALAXY, STAR FORMING REGION Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 5 INTERACTING- GALAXY, AMORPHOUS RA=12H37M44.8000S, J2000 V = 17.4 +/- 0.5 GAL-123745+1 IRREGULAR, INTERACTING DEC=+18D16'53.54" 81653 GALAXY, STAR FORMING REGION Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 6 GAL-222742-0 GALAXY, AMORPHOUS RA=22H27M41.2753S, J2000 V = 16.2 +/- 0.5 94337 IRREGULAR, INTERACTING DEC=-09D43'36.80" GALAXY, STAR FORMING REGION Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 7 GAL-222731-0 GALAXY, AMORPHOUS RA=22H27M30.7000S, J2000 V = 15.8 +/- 0.5 93954 IRREGULAR, INTERACTING DEC=-09D39'55.90" GALAXY, STAR FORMING REGION Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 8 INTERACTING- GALAXY, AMORPHOUS RA=14H49M49.9000S, J2000 V = 15.9 +/- 0.5 GAL-144950+3 IRREGULAR, INTERACTING DEC=+36D24'24.50" 62425 GALAXY, STAR FORMING REGION Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 15087( 7) - 13-Dec-2018 16:43:51 - [ 4] Visit: 01 (dm1647+21-VISIT1) Visit Requirements: On Hold Comments: Additional Comments: We aim to image the pair of merging dwarf galaxies that fit into one chip (UVIS2).
