cds-question@unistra.frgalaxiescatalogsvisible-astronomyspectroscopyredshiftedsurveysquasarsWe describe the survey for galaxies in the fields surrounding nine sightlines to far-UV bright, z~1 quasars that define the COS Absorption Survey of Baryon Harbors (CASBaH) program. The photometry and spectroscopy that comprise the data set come from a mixture of public surveys (SDSS, DECaLS) and our dedicated efforts on private facilities (Keck, MMT, LBT). We report the redshifts and stellar masses for 5902 galaxies within ~10 comoving-Mpc of the sightlines with a median of \bar{z}=0.28 and \bar{M}_*_~10^10.1^M_{sun}_. This data set, publicly available as the CASBaH specDB, forms the basis of several recent and ongoing CASBaH analyses. Here, we perform a clustering analysis of the galaxy sample with itself (auto-correlation) and against the set of O VI absorption systems (cross-correlation) discovered in the CASBaH quasar spectra with column densities N(O^+5^)>=10^13.5^/cm^2^. For each, we describe the measured clustering signal with a power-law correlation function {xi}(r)=(r/r_0_)^-{gamma}^ and find that (r_0_,{gamma})=(5.48+/-0.07h_100_^-1^Mpc,1.33+/-0.04) for the auto-correlation and (6.00_-0.77_^+1.09^h_100_^-1^Mpc,1.25+/-0.18) for galaxy-OVI cross-correlation. We further estimate a bias factor of b_gg_=1.3+/-0.1 from the galaxy-galaxy auto-correlation, indicating the galaxies are hosted by halos with mass M_halo_~10^12.1+/-0.05^M_{sun}_. Finally, we estimate an OVI-galaxy bias factor b_OVI_=1.0+/-0.1 from the cross-correlation which is consistent with OVI absorbers being hosted by dark matter halos with typical mass M_halo_~10^11^M_{sun}_. Future works with upcoming data sets (e.g., CGM2) will improve upon these results and will assess whether any of the detected OVI arises in the intergalactic medium.2019ApJS..243...24Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/243/24CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/317 : The CFHTLS Survey (T0007 release) (Hudelot+ 2012)II/314 : UKIDSS-DR8 LAS, GCS and DXS Surveys (Lawrence+ 2012)II/319 : UKIDSS-DR9 LAS, GCS and DXS Surveys (Lawrence+ 2012)I/337 : Gaia DR1 (Gaia Collaboration, 2016)II/347 : KiDS-ESO-DR3 multi-band source catalog (de Jong+, 2017)V/147 : The SDSS Photometric Catalogue, Release 12 (Alam+, 2015)J/A+AS/108/287 : Atomic data (Verner+, 1994)J/ApJ/508/200 : QSO low-z Ly{alpha} absorbers (Tripp+, 1998)J/ApJS/177/39 : Survey of low-redshift OVI absorbers (Tripp+, 2008)J/ApJ/701/1219 : Galaxy survey in 3 QSO fields (Chen+, 2009)J/ApJ/704/898 : Photometry of the Hercules dwarf galaxy (Sand+, 2009)J/ApJS/182/378 : HI and OVI absorbers in nearby Universe (Wakker+, 2009)J/MNRAS/405/2302 : Improved redshifts for SDSS quasar spectra (Hewett+, 2010)J/ApJS/193/28 : Galaxy survey around 20 UV-bright quasars (Prochaska+, 2011)J/ApJ/740/91 : Ly{alpha} & OVI in galaxies around QSOs (Prochaska+, 2011)J/ApJ/736/42 : HST QSO Catalog (Ribaudo+, 2011)J/ApJ/770/138 : Metallicities of Lyman limit systems and DLA (Lehner+, 2013)J/A+A/559/A85 : 1D Lya forest power spectrum (Palanque-Delabrouille+, 2013)J/ApJ/776/136 : QPQ VI.
