Theoretically the existence of dusty, massive startbursts at such early epochs is difficult to explain and thorough observational constraints on their properties provides a stringent test of galaxy formation models. Our targets were selected from the Herschel-HerMES survey and have a multitude of far-infrared follow-up data, including the CO spectroscopy that revealed their extreme redshifts. However, deep optical and near-IR observations are currently lacking and we require the resolution and sensitivity of HST at these wavelengths to completely reveal these rare galaxies. We will use the proposed data to measure the physical properties of four z>4 dusty starbursts, including their sizes, stellar masses, and the scale and mode of the star-formation. There is also evidence of gravitational lensing and the HST data are crucial for accurately measuring the lensing amplification and reconstructing the source plane. The wider field data will be used to investigate the environments of these galaxies and determine whether they are protocluster members, as often expected of massive high-redshift galaxies and similarly to some other z>4 starbursts. We will be able to measure the dark matter halo mass scale and thereby consider the evolution and descendent of these galaxies, particularly in comparison with lower redshift dusty starbursts. ------------------------------------------------------------------------------------ Observations Description ------------------------ 13718( 4) - 21-Aug-2014 15:33:31 - [ 2] Observing_Description: We require WFC3 observations with the F105W and F160W filters of four dusty z>4 target galaxies. For three of the targets WFC3 observations in both filters will be completed in a single orbit per target. The final target requires two WFC3 orbits. (Total = 5 WFC3 orbits) We also require ACS F435W observations for three of the four targets to definitively identify any foreground galaxies, which may be gravitationally lensing the z>4 starburst galaxies. These observations require one orbit per target. (Total = 3 ACS orbits). For the WFC3 observations we calculate predicted F105W and F160W fluxes of our targets by scaling the SED of Arp220 to the observed far-infrared fluxes, fixed to the CO redshifts. As described in the proposal, there is some exvidence of the targets being marginally resolved in existing low SNR data, and therefore the required WFC3 exposure times are ~4x those calculated from the fluxes alone, and ~4x those in each of the ETC references. The z>4 SMGs will be undeteced in the ACS observations (due to the redshift and the lyman limit), instead those observations aim to characterise any foreground lensing galaxies. Therefore, the predicted fluxes in the ACS/F435W images are estimated based on non-dusty galaxy SEDs at z = 2, scaled to the flux of the faintest detected stellar components. As described in the proposal, the possible foreground galaxy in exisiting RARE-LSW-102 observations is also marginally resolved and therefore also requires ~4x the exposure calculated from the fluxes alone and in the ETC reference. There are no constraints on observing date or orientation. ------------------------------------------------------------------------------------ 13718( 4) - 21-Aug-2014 15:33:31 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 RARE-LSW-102 GALAXY, HIGH REDSHIFT RA=10H40M50.6160S +/- 0.5", J2000 Z = 5.29 V = 25.0 +/- 1 F435W expected =25.5 GALAXY, STARBURST DEC=+56D06'53.88" +/- 0.5" ABmag, F105W expected=24.1 ABmag, F160W expected =23.4 ABmag Reference Frame: ICRS Comments: F435W flux is estimated for a foreground lens (z=2 assumed) rather than the z~5 target. ------------------------------------------------------------------------------------------------------------------------------------ 2 RARE-FLS-1 GALAXY, HIGH REDSHIFT RA=17H08M17.5872S +/- 1", J2000 Z = 4.29 V = 26.7 +/- 1 F105W expected = 24.6 GALAXY, STARBURST DEC=+58D28'40.46" +/- 0.5" ABmag, F160W expected = 23.9 ABmag Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 3 RARE-HELMS-1 GALAXY, HIGH REDSHIFT RA=00H52M58.5401S +/- 1", J2000 Z = 4.37 V = 26.2 +/- 0.5 F435W expected = 26.7 0 GALAXY, STARBURST DEC=+06D13'19.20" +/- 1" ABmag, F105W expected = 24.0 ABmag, F160W expected= 23.2 ABmag Reference Frame: ICRS Comments: F435W flux is estimated for a foreground lens (z=2 assumed) rather than the z~5 target. ------------------------------------------------------------------------------------------------------------------------------------ 4 RARE-HELMS-2 GALAXY, HIGH REDSHIFT RA=00H44M10.2799S +/- 1", J2000 V = 26.2 +/- 1 F435W expected = 26.7 8 GALAXY, STARBURST DEC=+01D18'22.30" +/- 1" ABmag, F105W expected = 24.0 ABmag, F160W expected = 23.2 ABmag Reference Frame: ICRS Comments: F435W flux is estimated for a foreground lens (z=2 assumed) rather than the z~5 target. ------------------------------------------------------------------------------------------------------------------------------------ 13718( 4) -
