We present a deep redshift survey in the field of 1ES1553+113, a blazar with a unique combination of ultraviolet (UV)+X-ray spectra for surveys of the circumgalactic/intergalactic medium (CGM/IGM). Nicastro+ (2018Natur.558..406N) reported the detection of two OVII WHIM absorbers at z=0.4339 and 0.3551 in its spectrum, suggesting that the WHIM is metal rich and sufficient to close the missing baryons problem. Our survey indicates that the blazar is a member of a z=0.433 group and that the higher-z OVII candidate arises from its intragroup medium. The resulting bias precludes its use in baryon censuses. The z=0.3551 candidate occurs in an isolated environment 630kpc from the nearest galaxy (with stellar mass logM_*_/M_{sun}_~9.7), which we show is unexpected for the WHIM. Finally, we characterize the galactic environments of broad HI Ly{alpha} absorbers (Doppler widths of b=40-80km/s; T<~4x10^5^K) that provide metallicity-independent WHIM probes. On average, broad Ly{alpha} absorbers are ~2x closer to the nearest luminous (L>0.25L*) galaxy (700kpc) than narrow (b<30km/s; T<~4x10^5^K) ones (1300kpc) but ~2x further than OVI absorbers (350kpc). These observations suggest that gravitational collapse heats portions of the IGM to form the WHIM, but with feedback that does not enrich the IGM far beyond galaxy/group halos to levels currently observable in UV/X-ray metal lines.2019ApJ...884L..31Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/884/L31CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/701/1219 : Galaxy survey in 3 QSO fields (Chen+, 2009)J/ApJS/193/28 : Galaxy survey around 20 UV-bright quasars (Prochaska+, 2011)J/MNRAS/434/1765 : Catalog of galaxies around PKS 0405-123 (Johnson+, 2013)J/A+A/570/A126 : XShooter spectrum of 4 BL Lacs (Landoni+, 2014)J/MNRAS/445/2061 : Absorption in multiphase CGM (Liang+, 2014)J/MNRAS/449/3263 : Extended galaxy halo gas through HI and OVI (Johnson+, 2015)J/ApJ/817/111 : HST/COS survey of z<0.9 AGNs.
