----- Attempting Submission 2 (Mon Nov 25 17:09:57 GMT 2024) -----The first multi-phase survey of the circumgalactic medium of quasar hosts at z<1Feedback from quasars plays a vital role in galaxy evolution, but the relationship between quasars and the circumgalactic medium (CGM) that dominates baryon reservoirs and provides a record of feedback is not well constrained. The cool CGM of quasar hosts observed on 100 kpc scales is strongly correlated with the quasar luminosity and exceeds that of non-AGN galaxies by 2x, even though BH accretion occurs at <1 pc. These observations provide evidence for a connection between AGN activity and the CGM despite the large difference in scale. The observed CGM-quasar connection can result from (1) winds associated with quasar feedback or (2) debris from interactions thought to trigger luminous quasars. If the correlation is due to feedback, the observed low-ionization gas results from entrainment or cooling in a hot wind, predicting significant highly ionized absorption and high metallicity. Lower ionization species will dominate if the correlation is driven by debris from interactions. We propose testing these possibilities through a multi-phase study of the CGM of the only nine quasars at z<1 with NUV-bright background probes at d<160 kpc. The proposed UV spectra will cover the HI Lyman series and a suite of low-to-high ions including CII, CIII, and OVI to enable: (1) accurate measurements of N(HI) and metallicities, (2) comparison of the kinematics of gas in different ionization states, and (3) a multi-phase CGM comparison of the eight quasars with inactive galaxies in the literature. The proposed UV spectra will test the quasar feeding vs. feedback scenarios through ionization analysis and kinematic comparison with nearby galaxies revealed in ongoing ground-based surveys.This program will observe COS FUV spectra with the PSA in medium-resolution mode of background quasars probing the CGM of foreground quasars. The foreground quasars range in redshift between z=0.29 and z=0.7, placing the absorption features of interest (the HI Lyman series, CIII, and OVI, for example) in different parts of the FUV spectral coverage. This requires observations of G130M and/or G160M and associated cenwave settings that are customized for each quasar. The details of the spectroscopic disperser and cenwave choice for each system are given in the comments associated with the visits. In some cases, no features fall in segment gaps, so we observe fewer cenwave settings to minimize overheads without loss of scientific return on the CGM absorption spectra at the redshift of the foreground quasar. In other cases, the observations include multiple cenwave settings to fill the segment gap or cover features near the edges of the G130M or G160M coverage. To ensure spectral quality in the coadded COS spectra, we observe multiple FP-POS settings. We note that the S/N requirement for the proposed Lya observations (when needed) are significantly lower than the metal ions and rest of the HI Lyman series because the Lya observations are only designed to constrain the presence or absence of damping wings, which will be performed on heavily rebinned spectra.
Acquisition: All targets are detected in GAIA and, therefore, have highly accurate coordinates. Moreover, all are detected in GALEX, ensuring good UV brightness constraints. As a result, we use the ACQ/IMAGE acquisition mode which provides good centering of the quasars in the science aperture with minimal overheads. We use Mirror A whenever possible, but use Mirror B when required for brighter sources.
Visit strategy: To minimize overheads while maintaining schedulability, we pack visits with 2-4 orbits each.
The UV bright quasars are not expected to be extended in the FUV channel and a search of the GAIA archive reveals that none have nearby sources that would fall within the 2.5" PSA and contaminate the COS spectrum. We therefore do not set the EXTENDED flag for the sources.PI S. Johnson and co-I's H.-W. Chen, J. Mulchaey, F. Zahedy, G. Rudie, E. Boettcher, Z. Qu, and B. Weiner are experts in studies of the CGM through UV absorption spectroscopy. Collectively, this team has extensive experience with both COS and ground-based echelle spectroscopy. We have published over >20 papers involving HST UV spectra, >10 of which were published in the last five years. Together, this team has the experience and expertise necessary to conduct the proposed absorption spectroscopy, measurements, and ionization modelling.
Co-I's J. Greene, G. Walth and J. Li are experts in studies of galaxy and AGN/quasar populations with extensive experience in multi-wavelength observations including HST imaging and spectroscopy. G. Walth and J. Li in particular is an expert in HST imaging and will lead in analysis involving the archival HST images of the fields.
Co-I J. Schaye is an expert in theoretical models and simulations of galaxy evolution, AGN, and quasars whose contribution will enable comparisons with theoretical expectations and broad context. In particular, J. Schaye is the PI of the EAGLE simulations which will be used to compare our observations with predictions from simulations, including non-equilibrium effects.
S. Johnson, H.-W. Chen, and J. Mulchaey, led the 2015 study of MgII absorption in the CGM of quasars that motivated this proposal.

With institutional access to both Magellan and MMT, we will complement the proposed UV observations and archival HST images with both high resolution echelle spectra of the background quasars, redshift surveys of the field, and deep, wide integral field spectrograph observations of the fields.Supermassive Black Holes and Active GalaxiesIntergalactic Medium and the Circumgalactic Medium6falsetruefalsefalsefalsefalsefalseSUPPORTEDGALAXYQSONOJ2000J2000NUV=18.9GALAXYQSONOJ2000J2000NUV=17.7GALAXYQSONOJ2000J2000NUV=18.7GALAXYQSONOJ2000J2000NUV=19.0GALAXYQSONOJ2000J2000NUV=17.7GALAXYQSONOJ2000J2000NUV=18.8GALAXYQSONOJ2000J2000NUV=18.8GALAXYQSONOJ2000J2000NUV=18.5GALAXYQSONOJ2000J2000NUV=18.8COS/FUVSpectroscopicNoNoG130M1222COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG160M1533COS/FUVSpectroscopicNoNoG160M1577COS/FUVSpectroscopicNoNoG160M1623COS/FUVSpectroscopicNoNoG160M1611COS/FUVSpectroscopicNoNoG160M1600COS/FUVSpectroscopicNoNoG160M1623COS/FUVSpectroscopicNoNoG160M1611COS/FUVSpectroscopicNoNoG160M1600COS/FUVSpectroscopicNoNoG130M1222COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG160M1533COS/FUVSpectroscopicNoNoG160M1533COS/FUVSpectroscopicNoNoG160M1577COS/FUVSpectroscopicNoNoG160M1589COS/FUVSpectroscopicNoNoG160M1533COS/FUVSpectroscopicNoNoG160M1577COS/FUVSpectroscopicNoNoG160M1589COS/FUVSpectroscopicNoNoG130M1222COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG160M1533COS/FUVSpectroscopicNoNoG160M1577COS/FUVSpectroscopicNoNoG160M1589COS/FUVSpectroscopicNoNoG130M1222COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG130M1222COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG160M1533COS/FUVSpectroscopicNoNoG160M1577COS/FUVSpectroscopicNoNoG160M1589COS/FUVSpectroscopicNoNoG130M1222COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG160M1533COS/FUVSpectroscopicNoNoG160M1577COS/FUVSpectroscopicNoNoG160M1533COS/FUVSpectroscopicNoNoG160M1577COS/FUVSpectroscopicNoNoG160M1589COS/FUVSpectroscopicNoNoG160M1533COS/FUVSpectroscopicNoNoG160M1577COS/FUVSpectroscopicNoNoG160M1589COS/FUVSpectroscopicNoNoG130M1222COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG160M1577COS/FUVSpectroscopicNoNoG160M1533The scheduling data was generated by CASM 32.1.3.CASM was run in Phase II mode.3 orbit G130M visit for background quasar J143624.3+353709.4 at redshift z=0.767 probing the CGM of a quasar at z=0.3916.

At this redshift, key features in the G130M spectral coverage covers all desired features except for Lya.
Because the S/N requirement for Lya is low (SNR=3 per resolution element) given that the goal is only to detect broad wings if they are present, we only observe one G160M cenwave with one FP-POS setting.
This visit completes G130M with one orbit and contains both G160M orbits for this target.1742468357000262.4008436849941(Tic-Visit
