Its kinematics, ionization state, and metal enrichment place vital constraints on the baryon cycle, including the amount of metals produced by previous generations of stars and the dispersal of metals though feedback processes. The CIV doublet is a strong tracer of warm-ionized outflows. It is also the strongest ionic probe at z>2 and the only high-ionization transition available at z>6, but poorly constrained at z<2 when the cosmic star formation rate density declines rapidly. This proposal will fill a prominent gap between low- and high-redshift CGM studies by targeting CIV with STIS E230M, which offers higher spectral resolution and higher efficiency than the COS NUV channel. It leverages existing FUV spectra and deep galaxy surveys to provide the most comprehensive census of cosmic enrichment to date. The proposed STIS NUV E230M data (which trace 2 ionization states of C and 3 of Si) combined with archival FUV spectra will resolve the complex, multiphase CGM. The program will deliver a legacy galaxy-absorber sample, covering more than four decades in stellar mass and two decades in projected distance, for studying the cosmic baryon cycle. It will (1) establish the census of heavy elements (C and Si) in warm-ionized gas from z~0 through the epoch of reionization, (2) characterize CGM chemical enrichment and 17517( 9) - 21-Jul-2025 18:13:50 - [ 2] its connection to galaxy properties over the full cosmic history, and (3) resolve the ionization states and thermodynamics of the turbulent CGM. JWST has just begun to unravel the CIV CGM properties at z~6, highlighting the urgent need to complete the census of metals across cosmic time. ------------------------------------------------------------------------------------ Observations Description ------------------------ Summary of Program Goals: This program aims to obtain high-quality NUV spectra of 15 QSOs, using STIS and the E230M grating to cover the wavelength from 2000 Ang to 2800 Ang with a spectral reolution of ~ 10 km/s. All 15 NUV bright QSOs have been previously and successfully observed with COS. The primary scientific objectives are to: (1) provide a census of the cosmic carbon and silicon mass budgets based on surveys of the CIV 1548, 1550 and SiIV 1392, 1402 absorption transitions at redshift z~0.4-0.8, (2) characterize the cosmic evolution of the circumgalactic medium and its connection to galaxy properties, and (3) constrain the thermal and ionization states of the multiphase gas around galaxies based on spectrally-resolved absorption profiles. STIS Configuration and visit schedules: The program will employ the E230M grating with a central wavelength of 2415 Ang and the 0.2"x0.2" aperture to reach a spectral resolving power of R~30000 (or equivalently FWHM~10 km/s). The central wavelength is selected to provide the spectral coverage of 2000-2800 Ang necessary for observing the CIV 1548, 1550 doublet at redshift z<~0.8. The STIS MAMA dark monitor pages shows ~25% increase in the dark current level after the high voltage is on for two hours and remains at the same level up to eight hours. With a constant 25% increase in the dark current over the 8 hours after the high voltage is turned on (https://www.stsci.edu/hst/instrumentation/stis/performance/monitoring), we request our observations to be scheduled and completed within 8 hours of turning on the MAMA detector. Because this is point source spectroscopy, no orient constraint is necessary. The total exposure time for each QSO ranges from 2 to 15 orbits. Following the recommendations stated in the STIS instrument handbook (https://hst-docs.stsci.edu/stisihb/chapter-2-special-considerations-for-cycle- 31/2-6-scheduling-efficiency-and-visit-orbit-limits), the observations will be carried out in visits of 2 to 3 orbits. Target Acquisition: The quasar coordinates are known to better than 0.1" and all 15 NUV bright QSOs have been previously and successfully observed with COS. An ACQ sequence is sufficient to center the quasar in the 0.2"x0.2" aperture at the beginning of each visit. The GALEX NUV magnitudes of the quasars range from AB(NUV)=15.5 to AB(NUV)=16.9. Using the STIS Target Acquisition ETC, we find that S/N >~ 40 can be reached over durations of 0.2 to 0.7 seconds. ------------------------------------------------------------------------------------ 17517( 9) -
