TL;DR
This study models the ram pressure stripping of galaxy ESO 137-001, reproducing multi-wavelength observations and predicting gas distributions and galaxy orbit within the Norma cluster.
Contribution
The paper introduces new dynamical simulations and analytical estimates of gas mixing, providing detailed models that match observed emissions and constrain the galaxy's orbit.
Findings
Models reproduce observed CO, Halpha, and X-ray features.
Ram pressure acts more face-on with an angle of 60-75 degrees.
Predicted HI distributions and galaxy orbit are consistent with observations.
Abstract
Ram pressure stripping of the spiral galaxy ESO 137-001 within the highly dynamical intracluster medium (ICM) of the Norma cluster lead to spectacular extraplanar CO, optical, H, UV, and X-ray emission. The Halpha and X-ray tails extend up to 80 kpc from the galactic disk. Dynamical simulations of the ram pressure stripping event are presented to investigate the physics of the stripped gas and its ability to from stars, to predict HI maps, and to constrain the orbit of ESO 137-001 within the Norma cluster. Special care was taken for the stripping of the diffuse gas. In a new approach, we analytically estimate the mixing between the intracluster and interstellar media. Different temporal ram pressure profiles and the ICM-ISM mixing rate were tested. Three preferred models show most of the observed multi-wavelength characteristic of ESO 137-001. Our highest-ranked model best…
