The central engine of these quasars is a black hole of ~1e9 solar masses. In the local universe, such massive black holes only reside in the most massive galaxies. Detailed optical IFU observations VLT/MUSE have indeed revealed massive and extended gaseous reservoirs fueling intense episodes of star formation in z>6 quasar hosts. At the same time, high-resolution ALMA observations unveiled highly massive and star forming galaxies. However, to date, the host starlight remain elusive at such early cosmic times, due to surface brightness and wavelength range limitations. Here we propose to perform a survey of a sample of 9 QSOs at z>6 to image their host galaxy starlight in the rest-frame optical emission (which is a robust tracer of the stellar mass). For all these objects deep MUSE and ALMA observations shows the presence of extended gas reservoirs and dust. The ultimate goal of the project is to have direct constraints on the stellar distribution in these early active galaxies, and relate this information to the spatial distribution of gas and dust. This will allow us to investigate the interplay between star formation and the gas cycle in 16740( 8) - 05-Apr-2022 17:40:04 - [ 2] these systems. ------------------------------------------------------------------------------------ Observations Description ------------------------ We aim to characterize the rest-frame UV properties of 9 faint (J>26) host galaxies located underneath the central (unresolved) emission of 9 bright (J<21) QSOs at z>6. To achieve the required accuracy in the PSF modelling and in the detection of the low surface brightness emission from the QSO hosts we will image each field for one orbit with WFC3/IR F140W to achieve an AB magnitude of ~27 at 5-sigma. We will use the default 4-step box dither pattern (WFC3-IR-DITHER-BOX-MIN) with an increased dither step to avoid possible self-persistence issues due to the bright QSOs. This dither step will give adequate subpixel sampling to reconstruct nyquist-sampled (2pix/FWHM) images and it is a commonly used patthern for high-redshift studies, easing the search for PSF reference with the same sampling for PSF subtraction purposes. Each visit is divided in 4 Sub Exposures to facilitate the removal of cosmic rays. ------------------------------------------------------------------------------------ 16740( 8) - 05-Apr-2022 17:40:04 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 P323+12 GALAXY, QSO, QUASAR RA=21H32M33.1910S, J2000 Z = V = 35 J_AB=19.74 DEC=+12D17'55.26" 6.5881 Reference Frame: ICRS Extended: NO Comments: Two bright stars located withing the WFC3/IR FoV at: 21:32:30.15 +12:17:26.0 (i_AB~9.8mag) 21:32:35.21 +12:17:52.9 (i_AB~11.7mag) Nearby galaxy with K_AB=20.3mag located 1.6 arcsec NNE from the target QSO. ------------------------------------------------------------------------------------------------------------------------------------ 2 P036+03 GALAXY, QSO, QUASAR RA=02H26M1.8760S, J2000 Z = V = 35 J_AB=19.51 DEC=+03D02'59.39" 6.5412 Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 3 J2329-0301 GALAXY, QSO, QUASAR RA=23H29M8.2750S, J2000 Z = V = 35 J_AB=21.56 DEC=-03D01'58.80" 6.4164 Reference Frame: ICRS Extended: NO Comments: One bright star located at the edge of the WFC3/IR FoV at: 23:29:12.23 -03:02:29.05 (i_AB~10.2mag) ------------------------------------------------------------------------------------------------------------------------------------ 4 J1030+0524 GALAXY, QSO, QUASAR RA=10H30M27.0980S, J2000 Z = V = 35 J_AB=19.79 DEC=+05D24'55.00" 6.3000 Reference Frame: ICRS Extended: NO Comments: One bright star located within the WFC3/IR FoV at: 10:30:25.59, +05:24:25.71 (i_AB~12.5mag) ------------------------------------------------------------------------------------------------------------------------------------ 5 P065-26 GALAXY, QSO, QUASAR RA=04H21M38.0520S, J2000 Z = V = 35 J_AB=19.32 DEC=-26D57'15.60" 6.1877 Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 6 P359-06 GALAXY, QSO, QUASAR RA=23H56M32.4550S, J2000 Z = V = 35 J_AB=19.85 DEC=-06D22'59.26" 6.1722 Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 7 P340-18 GALAXY, QSO, QUASAR RA=22H40M48.9970S, J2000 Z = V = 35 J_AB=20.28 DEC=-18D39'43.81" 6.0100 Reference Frame: ICRS Extended: NO Comments: One bright star located withing the WFC3/IR FoV at: 22:40:48.77 -18:39:27.7 (i_AB~15.7mag) ------------------------------------------------------------------------------------------------------------------------------------ 8 P009-10 GALAXY, QSO, QUASAR RA=00H38M56.5220S, J2000 Z = V = 35 J_AB=19.93 DEC=-10D25'53.90" 6.0039 Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 9 J2228+0110 GALAXY, QSO, QUASAR RA=22H28M43.5350S, J2000 Z = V = 35 J_AB=20.90 DEC=+01D10'32.20" 5.9030 Reference Frame: ICRS Extended: NO Comments: One fairly faint star located close to the target: 22:28:43.03 +01:10:38.89 (i_AB~18.1mag) 16740( 8) - 05-Apr-2022 17:40:04 - [ 4] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------------------------------------------ 16740( 8) - 05-Apr-2022 17:40:04 - [ 5] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 1 Primary_Pattern Secondary_Pattern Pattern_Type WFC3-IR-DITHER-BOX-MIN Pattern_Purpose DITHER Number_Of_Points 4 Point_Spacing 4.004 Line_Spacing 4.015 Coordinate_Frame POS-TARG Pattern_Orient 18.528 Angle_Between_Sides 74.653 Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ 16740( 8) - 05-Apr-2022 17:40:04 - [ 6] Visit: 01 (P323+12) Visit Requirements: ORIENT 21.7D TO 39.6 D;
