However, studying these inherently multiphase environments from a multiphase perspective, i.e., systematically characterizing the diffuse cool and hot gas in groups and clusters, has remained elusive due to the relatively small numbers of X-ray detected halos to target in UV absorption line experiments. The eROSITA All Sky Survey (eRASS) is dramatically changing the landscape with an order-of-magnitude increase in the number of X-ray detected groups and clusters after only the first year of observations. We propose to obtain HST/COS spectra of quasars probing a sample of eRASS-detected galaxy groups and clusters spanning two orders of magnitude in X-ray luminosity, representing the first study of its kind and tripling the previously 17774( 5) - 11-Feb-2026 17:11:18 - [ 2] existing samples. First, we will track the cool gas, traced by H I Ly-alpha and Si III, contents in and around these halos as a function of the X-ray derived properties. Using ongoing follow-up spectroscopic surveys for these groups/clusters, we will characterize the CGM contents of galaxies near the sightlines to investigate the impact of increasing hot gas density and temperature (via the X-ray measurements) on these galaxies. Hydrodynamical simulations have been highly inconsistent in reproducing the few existing observations, and the dataset from our program will stand as a critical benchmark for state-of-the-art models that attempt to capture the salient multiphase gas physics in massive halos. ------------------------------------------------------------------------------------ Observations Description ------------------------ To achieve our science goals, we will employ the G130M grating providing ~20 km s^-1 spectral resolution. We will primarily target H I Lya at the cluster's redshifts. The G130M central wavelength configurations chosen for each target ensures coverage of not only Lya, but also some transitions of silicon. Mission critical for our science is coverage of Lya with sufficient S/N; we have chosen grating configurations to maximize throughput at the H I Lya line. We will also cover Si III 1206 Ang, and additional metal lines (Si II 1190, 1193 Ang, and Si II 1260 Ang for a majority of our targets) will supplement our key scientific objectives but are not the focus of this proposal. Our orbit requests are derived from an S/N = 10 requirement at Lya, which corresponds to a limiting equivalent width ~40 mAng assuming a line width of 6 pixels, with exposure time estimates determined by the COS ETC. We do not require coverage of Lyb because we expect most of the H I Lya absorption to be optically thin. Even in the conditions where this is not the case, we can place reliable lower limits on N (H I). We will employ a routine observing sequence for COS. We will acquire the targets in the near-UV with an ACQ/IMAGE exposure then switch to TIME-TAG for our science exposures. To comply with guidelines as outlined in the COS Handbook and minimize flat-field artifacts, we will use multiple FP-POS settings during each visit. ------------------------------------------------------------------------------------ 17774( 5) - 11-Feb-2026 17:11:18 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 2MASSJ104437 GALAXY, QSO RA=10H44M37.4735S +/- 0.08950", J2000 V = 17.428 FUV=17.90416145 48-0705162 DEC=-07D05'16.19" +/- 0.08950" Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 2 2MASXJ083703 GALAXY, QSO, QUASAR RA=08H37M3.2990S +/- 0.11325", J2000 V = 18.353 FUV=18.27466202 34+2508153 DEC=+25D08'15.23" +/- 0.11175" Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 3 B21229+29 GALAXY, QSO, QUASAR RA=12H31M43.5685S +/- 0.0835", J2000 V = 17.415 FUV=18.17481613 DEC=+28D47'49.70" +/- 0.082" Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 4 EQSB1255-014 GALAXY, QSO, QUASAR RA=12H58M15.2192S +/- 0.10075", J2000 V = 17.561 FUV=17.83533859 3 DEC=-01D59'18.69" +/- 0.10050" Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 5 LEONX-1 GALAXY, QSO, QUASAR RA=05H19M36.3293S +/- 0.08950", J2000 V = 17.45 FUV=18.03486061 DEC=-60D48'3.96" +/- 0.08700" Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 6 MS10302-2757 GALAXY, QSO, QUASAR RA=10H32M36.0689S +/- 0.08350", J2000 V = 16.414 FUV=16.50211716 DEC=-28D13'26.90" +/- 0.08300" Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 7 PGC3095905 GALAXY, QSO, QUASAR RA=09H54M29.5818S +/- 0.07975", J2000 V = 15.436 FUV=17.85335732 DEC=-16D06'51.21" +/- 0.07800" Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 8 PGC955931 GALAXY, QSO, QUASAR RA=03H03M15.5743S +/- 0.08750", J2000 V = 16.695 FUV=18.46393776 DEC=-12D13'29.84" +/- 0.08325" Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 9 SDSSJ101314.
