They probe multiple locations in the inner regions (d<10 kpc) of the massive lensing galaxies, unveiling the complex properties of diffuse gas from interstellar to circumgalatic space. While most massive galaxies are quiescent, recent studies reveal that they can harbor significant cool (T~1E4 K) gas in their halos. Such findings challenge the notion that their lack of star formation is caused by an absence of gas, and imply that complex feedback/environmental processes are at play. We have identified a sample of 8 massive (M_star>1E11 M_sun) lens galaxies at z=0.3-0.8, with 16 lensed QSO images suitable for UV spectroscopy (two per galaxy) situated at d<10 kpc. Two lensed QSOs have UV spectra available in the HST archive. We propose new STIS/UV spectroscopy with the G140L/G230L gratings for the remaining six QSOs. The wide spectral coverage enables detection of the full HI Lyman series, necessary to probe the bulk of the gas content, and various ionic metals tracing multiple gas ionization states. The main objectives are to (1) map N(HI) and its spatial variations on <10 kpc scales, (2) constrain the multiphase gas properties and explore their implications for feedback, and (3) characterize the chemical abundances and resolve the physical origin of the gas (aided by high-resolution spectra from the ground). Our program will provide critical insights into massive galaxy evolution and quadruple the number of massive galaxies at z>0 with spatially resolved multiphase gas properties. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will obtain low-resolution (R~1000) FUV and NUV spectra of six doubly imaged lensed QSOs using the MAMA detector of the Space Telescope Imaging Spectrograph (STIS). The primary goals of the proposed FUV spectroscopic observations are(1) determine N(HI) and its spatial variations in the ISM of the massive elliptical lens galaxies, and (2) constrain the chemical enrichment and physical origins of multiphase gas in massive quiescent galaxies. 17146( 7) - 16-Dec-2025 01:00:24 - [ 2] Depending on the redshift of the lens galaxy (between z=0.31 and z=0.75), we will obtain STIS observations with either (1) the G140L grating or (2) a combination of the G140L and G230L gratings. In each case, the chosen STIS configuration will guarantee full coverage of the entire HI Lyman series and additional ionic metal species for two sightlines per lens galaxy. Because the six gravitationally lensed QSOs have images that are separated by between 1.1'' and 3.0'', the available long-slit mode on STIS allows both QSO images in each system to be observed simultaneously, thereby maximizing observing efficiency (with the exception of target J106+4322AB, for which each of the two images will be observed individually due to scheduling constraints) Observing Strategy: The observations will be performed in a series of individual visits, each consisting of between two and three HST orbits. As we plan to observe both images of each lensed QSO simultaneously, we require the STIS long slit (52''x0.2'') to be aligned along the line connecting the two QSO images on the sky. This slit alignment corresponds to HST orientation (ORIENT) angles of between 45 and 298 degrees, using an offset angle of 45.35 degrees listed on Table 11.2 of the STIS Instrumental Hand Book. Additionally We also specify the alternate +180-deg rotated ORIENT values for the six lensed systems, in case it would help with schedulability. We allow a range of +/-0.5 degree (1-degree range) in the ORIENT angles. Given the 0.2"-wide long slit, the 1.1" to 3" separation of each pair, and the known PSF profile of the MAMA detector, our chosen range should still include a large majority (>80-90%) of the light from both QSO images in the slit while also allowing for flexibility in scheduling. We note that for two of our targets, B1152+199AB and J0246-0825AB, we have imposed a special requirement "SCHEDULABILITY 70%" to ensure schedulability within the cycle 30 observing period. While this choice results in a modest decrease in orbital visibility (a few minutes per orbit), its impact on the expected data quality is minimal. Onboard target acquisition of the brighter QSO image (image A) of each pair will be performed using STIS/CCD and the F28X50LP filter in the first orbit of each visit. We have confirmed that there is no brighter point source within a 5" radius from each of our target. Following guide star acquisition and target acquisition (or guide star reacquisition for subsequent orbits), we request 2 sub-exposures for each orbit, corresponding to 2 dither positions of the STIS-ALONG-SLIT dither pattern. To ensure that all spectra taken in different orbits will fall on different areas of the FUV-MAMA detector, we will employ a four- (for two-orbit visits) or six-point (for three-orbit visits) dither pattern with a separation of 0.3" between successive steps. Note that for target 7 (image B of J1206+4332), we will acquire the target by first acquiring the brighter image A, and then applying a small (~3") offset to reach image B. We have also confirmed that all bright sources within the aperture are safe for observations with the MAMA detector using the Bright Object Tool on APT. ------------------------------------------------------------------------------------ 17146( 7) - 16-Dec-2025 01:00:24 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 B1152+199AB GALAXY, GRAVITATIONAL RA=11H55M18.2900S +/- 0.1", J2000 Z = 1.02 V = 17.7 GALEX FUV(AB) = 18.87; NUV(AB) LENS, QSO, QUASAR DEC=+19D39'42.21" +/- 0.1" = 17.57 Reference Frame: ICRS Extended: NO Comments: Object is a doubly imaged QSO.
