Another X-ray UFO without a momentum-boosted molecular outflow

Abstract: We present Atacama Large Millimetre/submillimetre Array (ALMA) CO(1–0) observations of the nearby infrared luminous (LIRG) galaxy pair IRAS 05054+1718 (also known as CGCG 468-002), as well as a new analysis of X-ray data of this source collected between 2012 and 2021 using the Nuclear Spectroscopic Telescope Array (NuSTAR), Swift, and the XMM-Newton satellites. The western component of the pair, NED01, hosts a Seyfert 1.9 nucleus that is responsible for launching a powerful X-ray ultra-fast outflow (UFO). Our … Show more

“…UFOs probe nuclear flows, and they therefore most likely belong to the momentum-driven regime. It is thus expected that most of the sources in compilations of UFOs and galaxy-scale outflows are compatible with momentum-driven flows (e.g., Bonanomi et al 2023). Because nuclear wind is likely short lived, the observed UFOs may well not be causally related with the more long-lived galaxy-scale winds.…”
