MUSE-ALMA Haloes VII: Survey Science Goals & Design, Data Processing and Final Catalogues

Monthly Notices of the Royal Astronomical Society, Volume 516, Issue 4, November 2022, Pages 5618-5636 November 2022 The gas cycling in the circumgalactic regions of galaxies is known to be multi-phase. The MUSE-ALMA Haloes survey gathers a large multi-wavelength observational sample of absorption and emission data with the goal to significantly advance our understanding of the physical properties of such CGM gas. A key component of the MUSE-ALMA Haloes survey is the multi-facility observational campaign conducted with VLT/MUSE, ALMA and HST. MUSE-ALMA Haloes targets comprise 19 VLT/MUSE IFS quasar fields, including 32 $z_{\rm abs}
