Mapping the Extended Ly α Emission within the Circumgalactic Medium of Quasars Hosted by Dusty Starbursts with CubeCarve

We thank Jay Gonzalez Lobos for helpful discussions related to the original SMG-QSO MUSE targets and their useful comments on an advanced draft of this work. We also thank the anonymous referee for the detailed comments that helped improve the paper. We also want to thank Rosalie McGurk for support during the observations. This work is supported by the National Science Foundation (NSF) grants AST-1614326 and AST-2103251. Based on observations collected at the European Organisation for Astronomical Research in the Southern Hemisphere under ESO programs 0103.A-0296(A), 0102.A-0403(A), and 0102.A-0428(A), available from the ESO Science Archive Facility https://archive.eso.org/. The authors wish to recognize and acknowledge the very significant cultural role and reverence that the summit of Maunakea has always had within the indigenous Hawaiian community. We are most fortunate to have the opportunity to conduct observations from this mountain. Python functions and a Jupyter Notebook implementing CubeCarve v1.0.0 are publicly available on GitHub2 2 https://github.com/kevhall23/CubeCarve and on Zenodo doi:10.5281/zenodo.19056748 (K.
