Receipt: # 6369-3 For the best data quality, it is generally required to use all four FP-POS positions at a given COS cenwave (or 2 positions for certain exception cases). See extended explanation in the diagnostic browser. submitting revised PhaseII for the repeat observation of previously failed Orbit 1, Visit 4. The repeat observation is now named as "visit 8" -1940484254 ----- Attempting Submission 1 (Thu Aug 14 04:44:25 GMT 2025) ----- ----- Attempting Submission 2 (Tue Aug 26 21:43:47 GMT 2025) ----- ----- Attempting Submission 3 (Tue Jun 09 06:00:39 GMT 2026) ----- I am resubmitting phase II for the previoulsy orbit of failed visit 4. I have kept the same configurations of that failed orbit. The APT is throwing an error of using all FP-POS, which I do for the entire visit combined. But this is just part of the visit. I cannot make the error go away but hopefully this is not an issue COS-RAD: Where Radio Jets Meet the Halo gas We propose COS-RAD, a 26-orbit HST/COS program to conduct the first UV absorption-line survey of the circumgalactic medium (CGM) in powerful FRII radio galaxies at z<0.6. While JWST is now exposing how radio jets disturb gas on ISM scales, COS-RAD will reveal their large (halo)-scale impact-- probing how mechanical jet-driven feedback alters the ionization, kinematics, and mass of multiphase gas in the CGM. We will observe 7 carefully selected radio galaxies using bright background quasars whose sightlines pass through the jet-inflated shocked cocoon region, aligned near the jet axis where feedback effects are strongest. Using primarily the G130M/1291 grating, we will detect the full suite of UV absorption lines, from neutral species to highly ionized tracers like OVI, capturing the CGM's thermal structure, ionization state, and gas flows. COS-RAD addresses two fundamental science goals: (1) Constrain the extent, ionization, and metal content of shocked gas in jet-inflated cocoons, and (2) Test whether radio jets dynamically disturb or accelerate CGM gas, producing distinct kinematic signatures compared to non-jetted systems. These observations will deliver the first direct, multiphase constraints on how radio-mode feedback reshapes galaxy halos, which is crucial for anchoring jet feedback models in cosmological simulations. Only HST/COS provides access to the UV diagnostics needed to probe the CGM gas across a range of ionization potentials and densities, and to uncover this hidden phase of AGN feedback. We select a sample of classical FRII radio galaxies from combined FIRST+VLASS surveys, and cross matched with SDSS quasars to build a sample of background quasars with foreground radio galaxies. Radio galaxies of interest lie between 0.2 < z < 0.4 with one source at z = 0.7, and the background quasar targets are at redshifts z~0.49 to 1.33. The background quasars have GALEX FUV mags between 18.5 - 19.33. For the target acquisition, we ask for SN = 40 for a point source of flat continuum SED, and flux normalized by the known GALEX magnitudes of each target. we ask for MIRRORA configuration. This yields Target acquisition times of ~6 to 9 seconds. For spectroscopy of 6 out of 7 sources, we use G130M/1291 setting to cover all the key emission lines of the Radio galaxies. We require SN ~8-10 at 1250 A where most lines line, and a minimum SN > 5 at 1400 A where throughput is the lowest. Using COS ETC, we find that the required times range from 3 to 5 orbits. For the 7th source, we use G160M/1611. We request total 26 orbits to observe 7 quasar sightlines, which probes the CGM of 7 FRII radio galaxies in absorption.
