Paper doi abstract bibtex Cool gas (T\${\textbackslash}sim\$10\${\textasciicircum}\{4\}\$\textasciitildeK) traced by hydrogen Ly\${\textbackslash}alpha\$ emission is now routinely detected around \$z{\textbackslash}sim3\$ quasars, but little is known about their molecular gas reservoirs. Here, we present an APEX spectroscopic survey of the CO(6-5), CO(7-6) and [CI](2-1) emission lines for 9 quasars from the QSO MUSEUM survey which have similar UV luminosities, but very diverse Ly\${\textbackslash}alpha\$ nebulae. These observations (\${\textbackslash}langle{\textasciitilde}{\textbackslash}rm rms{\textasciitilde}{\textbackslash}rangle=2.6\$\textasciitildemJy in 300\textasciitildekm\textasciitildes\${\textasciicircum}\{-1\}\$) detected three CO(6-5) lines with 3.4\${\textbackslash}leq I_\{{\textbackslash}rm CO(6-5)\} {\textbackslash}leq\$5.1\textasciitildeJy\textasciitildekm\textasciitildes\${\textasciicircum}\{-1\}\$, 620\${\textbackslash}leq\$FWHM\${\textbackslash}leq\$707\textasciitildekm\textasciitildes\${\textasciicircum}\{-1\}\$, and three [CI](2-1) lines with 2.3\${\textbackslash}leq I_\{{\textbackslash}rm [CI](2-1)\} {\textbackslash}leq\$15.7\textasciitildeJy\textasciitildekm\textasciitildes\${\textasciicircum}\{-1\}\$, 329\${\textbackslash}leq\$FWHM\${\textbackslash}leq\$943\textasciitildekm\textasciitildes\${\textasciicircum}\{-1\}\$. For the CO and [CI] detected sources, we constrain the molecular gas reservoirs to be \${\textbackslash}rm M_\{H_\{2\}\} = (0.4-6.9) {\textbackslash}times 10{\textasciicircum}\{11\} M_\{{\textbackslash}odot\}\$, while the non-detections imply \${\textbackslash}rm M_\{H_\{2\}\} {\textless} 1.1{\textbackslash}times 10{\textasciicircum}\{11\} M_\{{\textbackslash}odot\}\$. We compare our observations with the extended Ly\${\textbackslash}alpha\$ properties to understand the link between the cool and the molecular gas phases. We find large velocity shifts between the bulk of Ly\${\textbackslash}alpha\$ and the molecular gas systemic redshift in five sources (from \${\textbackslash}sim\$-400 to \${\textbackslash}sim+\$1200\textasciitildekm\textasciitildes\${\textasciicircum}\{-1\}\$). The sources with the largest shifts have the largest Ly\${\textbackslash}alpha\$ line widths in the sample, suggesting more turbulent gas conditions and/or large-scale inflows/outflows around these quasars. We also find that the brightest (\$I_\{{\textbackslash}rm[CI](2-1)\}=15.7{\textbackslash}pm3.7{\textasciitilde}{\textbackslash}rm Jy{\textasciitilde}km{\textasciitilde}s{\textasciicircum}\{-1\}\$) and the widest (FWHM\${\textbackslash}sim\$900\textasciitildekm\textasciitildes\${\textasciicircum}\{-1\}\$) lines are detected for the smallest and dimmest Ly\${\textbackslash}alpha\$ nebulae. From this, we speculate that host galaxy obscuration can play an important role in reducing the ionizing and Ly\${\textbackslash}alpha\$ photons able to escape to halo scales, and/or that these systems are hosted by more massive halos.
