Here we intend to extend studies of this kind to the most massive lens galaxies known to date, well outside the mass limits investigated by previous lensing surveys. This will allow us to probe the physics of the likely descendants of the most violent episodes of star formation and of the compact massive galaxies at high redshift. We propose WFC3 imaging (F438W and F160W) of four extremely massive early-type lens galaxies at z ~ 0.5, in order to put them into context with the evolutionary trends of ellipticals as a function of mass and redshift. These systems were discovered in the SDSS and show one single main lens galaxy with a stellar mass above 1.5x10^12 Msun and large Einstein radii. Our high-resolution spectroscopic follow-up with VLT/X-shooter provides secure lens and source redshifts, between 0.3 and 0.7 and between 1.5 and 2.5, respectively, and confirm extreme stellar velocity dispersions >~400 km/s for the lenses. The excellent angular resolution of the proposed WFC3 imaging - not achievable from the ground - is the remaining indispensable piece of information to : (1) Resolve the lens structural parameters and obtain robust measurements of their stellar mass distributions, (2) Model the amount and distribution of the lens total masses and measure their M/L ratios and stellar IMF with joint strong lensing and stellar dynamics analyses, (3) Enhance our on-going lens models through the most accurate positions and morphologies of the blue multiply-imaged sources. This program aims to image the 4 ultra-massive lens galaxies in the target list. Each target is imaged in 2 filters (WFC3/UVIS F438W and WFC3/IR F160W), with 1 orbit per filter. All the orbits can be run independently of each other. One of the targets, CSWA31, falls about 50 arcsec away from a bright star with H~11. Since the primary targets (the lens and background lensed galaxies) are much fainter, we want to avoid the diffraction spikes of the bright star. Table 7.4 in P2PI specifies that to place the target along rows in UVIS, the orientation is target_angle +221 deg. For the IR aperture the angle is target_angle +224 deg. CSWA31 has a position angle of ~170 deg, which leads to the following orientation angles (with a +/-10 deg flexibility): ------- IR ORIENT: 170 +224 = 394 (= 34). Allow a +/-90 and-180 ORIENT and a +/-10 deg range. Allowed ORIENT ranges: 24 - 44 , 114 - 134, 204 - 224, 294 - 314 ------- UVIS ORIENT: 170 +221 = 391 ( =31 ). Allow a +90 and -180 ORIENT and a +/-10 deg range. Allowed ORIENT ranges: 21 - 41, 111 -131, 201 - 221, 291-311 Galaxies and the IGM Cosmology 6 false false false false false 0.0 0.0 false SUPPORTED GALAXY EINSTEIN RING ELLIPTICAL GRAVITATIONAL LENS J2000 J2000 g-band AB-mag from the SDSS: 21.48 +/- 0.12 GALAXY EINSTEIN RING ELLIPTICAL GRAVITATIONAL LENS J2000 J2000 g-band AB-mag from the SDSS: 22.52 +/- 0.44 GALAXY EINSTEIN RING ELLIPTICAL GRAVITATIONAL LENS J2000 J2000 g-band AB-mag from the SDSS: 19.38 +/- 0.02 GALAXY EINSTEIN RING ELLIPTICAL GRAVITATIONAL LENS J2000 J2000 g-band AB-mag from the SDSS: 19.70 +/- 0.04 WFC3/UVIS Imaging No No F438W WFC3/UVIS Imaging No No F438W WFC3/UVIS Imaging No No F438W WFC3/UVIS Imaging No No F438W WFC3/IR Imaging No No F160W WFC3/IR Imaging No No F160W WFC3/IR Imaging No No F160W WFC3/IR Imaging No No F160W POS-TARG DITHER 0.173 LINE 0.112 false false 81.785 4 23.884 WFC3-UVIS-DITHER-BOX 1 false POS-TARG DITHER 0.572 LINE 0.365 false false 74.653 4 18.528 WFC3-IR-DITHER-BOX-MIN 2 false /home/rcanameras/Documents/postdoc/proposals/HST/OP-cache/HST_prop_phaseII-v01.xml The scheduling data was generated by CASM 25.2.
