Receipt: # 2979-1 ----- Attempting Submission 2 (Fri Mar 25 10:37:08 GMT 2022) ----- HST Phase I Proposal 2979 successfully submitted. Receipt: # 2979-2 The number of orbits used exceeds the number allocated This phase II file is strongly based on the observing strategy of previous HST proposals with the same target goal: obtaining WFC3 UVIS and IR imaging of lensed quasars. The similar proposals are Cycle 25, 15320, P.I. Treu, and Cycle 26, 15652, P.I. Treu. The coordinates of our targets have been checked to be accurate to within an arcsecond. The flash values were increased to reach a total background of at least 12500e/arcsec^2, according to the ETC in both F475X and F814W filters, which I calculate to be the equivalent of the recommended 20 e/pixel. Update 11 April 2023: Added one-orbit visit for J0806+2006 after HOPR submission and TTRB review/acceptance for failed UVIS observations (see Visit 4) due to FGS not acquiring guide stars. Update 21 July 2023: Added two one-orbit visits for J1515+1511 and J1442+4055 after HOPR (92574, 92575) submission and TTRB review/acceptance for failed UVIS observations in Visits 01 and 03 respectively due to FGS not acquiring guide stars. Update 04 September 2023: Added one-orbit visit (12) for J1442+4055 to carry out the proposed UVIS observations (Visit 11) which had failed due to FGS failing to acquire stars (HOPR 92607). This is the second repeat for this orbit. The exposure time of one exposure had to be reduced by 23 seconds, and the FLASH increased by 1, in order to remove errors and warnings. Update 16 July 2024: Added one-orbit visit (13) for J1001+5027 following HOPR 92722 to redo the streaked IR F160W observations, including a short F475X exposure that was equally affected in the original visit. -368712514 ----- Attempting Submission 1 (Mon Jul 11 09:37:59 GMT 2022) ----- ----- Attempting Submission 2 (Tue Apr 11 09:24:12 GMT 2023) ----- HST Phase II Proposal 17199 successfully submitted.

Time-delay Cosmography with Strongly Lensed Quasars: Doubles vs. Quads Time delays of strongly lensed quasars provide an independent cosmological probe that is primarily sensitive to the Hubble constant, H0. The method relies on precise time-delay measurements from photometric monitoring of the quasar images, which has been accomplished so far for only 7 systems, including 6 quadruply imaged quasars (quads) and 1 doubly imaged quasar (double). With deep HST images and ground-based follow-up, the latest results give H0 = 73.7 +/- 1.5 km/s/Mpc, compatible with distance ladder measurements but in tension with Planck. Intriguingly, the one double yields the lowest value of H0. With the present HST WFC3 imaging proposal our goal is to obtain deep and sharp images of 8 doubles with precisely measured time-delays from decade-long monitoring campaigns and all other necessary ancillary data already in hand. This will make the number of doubles useful as cosmological probes comparable to that of quads, and 1- test for modelling systematics by separately considering doubles and quads, 2- demonstrate the potential of doubles, i.e. 85% of the lens population, for time-delay cosmography, which is particularly important in the context of Rubin-LSST, 3- measure H0 to 2.2% precision under the assumption of physically motivated models with doubles alone, 4- in the case of no modelling systematics between quads and doubles, to measure H0 to 1.6% in combination with quads, i.e. competitive to the best probes such as type-Ia supernovae but in a completely independent way. We will obtain multicolour images of a sample of doubly imaged quasars. For each target we will observe approximately 4 exposures in each filter. In the UVIS filters F475X and F814W we will use a 2-point dither pattern and obtain a short (50s) and long exposure at each position to avoid saturating the bright quasar images. In the IR channel filter F160W we use a 4-point dither pattern, and STEP100 readout sequence to guarantee sufficient dynamic range to expose both the bright quasar and the host galaxy. The PI and CoIs have expertise at all levels of time-delay cosmography with lensed quasars and their interpretation in terms of deriving cosmological parameters. This includes time-delay measurements, study of the direct lens environement, spectroscopy of the main lens with slit or IFU, weak lensing mass-mapping, detailed analysis of HST imaging for lens modeling.
