A Multiwavelength Study of ELAN Environments (AMUSE\${\textasciicircum}2\$): Detection of a dusty star-forming galaxy within the enormous Lyman \${\textbackslash}alpha\$ nebula at \$z=2.3\$ sheds light on its origin. Chen, C., Battaia, F. A., Emonts, B. H. C., Lehnert, M. D., & Prochaska, J. X. arXiv:2111.15375 [astro-ph], November, 2021. arXiv: 2111.15375Paper abstract bibtex We present ALMA observations on and around the radio-quiet quasar UM287 at \$z=2.28\$. Together with a companion quasar, UM287 is believed to play a major role in powering the surrounding enormous Ly\${\textbackslash}alpha\$ nebula (ELAN), dubbed the Slug ELAN, that has an end-to-end size of 450 physical kpc. In addition to the quasars, we detect a new dusty star-forming galaxy (DSFG), dubbed the Slug-DSFG, in 2 mm continuum with a single emission line consistent with CO(4-3). The Slug-DSFG sits at a projected distance of 100 kpc south-east from UM287, with a systemic velocity difference of \$-360{\textbackslash}pm30\$ km s\${\textasciicircum}\{-1\}\$ with respect to UM287, suggesting it being a possible contributor to the powering of the Slug ELAN. With careful modeling of SED and dynamical analyses it is found that the Slug-DSFG and UM287 appear low in both gas fraction and gas-to-dust ratio, suggesting environmental effects due to the host massive halo. In addition, our Keck long-slit spectra reveal significant Ly\${\textbackslash}alpha\$ emissions from the Slug-DSFG, as well as a Ly\${\textbackslash}alpha\$ tail that starts at the location and velocity of the Slug-DSFG and extends towards the south, with a projected length of about 100 kpc. Supported by various analytical estimates we propose that the Ly\${\textbackslash}alpha\$ tail is a result of the Slug-DSFG experiencing ram pressure stripping. The gas mass stripped is estimated to be about 10\${\textasciicircum}9\$ M\$_{\textbackslash}odot\$, contributing to the dense warm/cool gas reservoir that is believed to help power the exceptional Ly\${\textbackslash}alpha\$ luminosity.
