DESCRIPTION:Jellyfish galaxies provide a striking view of the interaction b
 etween galaxies and their surrounding\nenvironment. As galaxies move throug
 h the intracluster medium\, ram-pressure stripping can remove their\ninters
 tellar gas and produce extended\, asymmetric tails. These structures offer 
 a unique opportunity to study how environmental processes shape the evoluti
 on of galaxies\, yet the physical connection between the properties of the 
 host galaxy and those of its stripped material remains poorly understood.\n
 In this work\, we present a new framework to identify and characterize ram-
 pressure-stripped gas in galaxies\nfrom the IllustrisTNG50 cosmological sim
 ulation. We identify Jellyfish galaxies using the MARK–log param-\neter spa
 ce\, which provides a physically motivated characterization of galaxies dom
 inated by ram pressure. We then extend the phase-space approach of Min et a
 l. (2019) by incorporating the local gas density\, allowing the stripped ma
 terial to be identified on a particle-by-particle basis and its physical pr
 operties to be quantified. This approach enables us to move beyond a simple
  Jellyfish/non-Jellyfish classification and investigate the\nphysical prope
 rties of the tails themselves. In particular\, we explore the correlations 
 between the properties of the host galaxies\, their interaction with the in
 tracluster medium\, and the resulting tail properties\, including their ext
 ent and gas content. By connecting the conditions experienced by a galaxy w
 ith the structure produced by ram-pressure stripping\, this framework provi
 des a new way to investigate the physical mechanisms governing the formatio
 n and evolution of Jellyfish tails.\n\nImported from https://www.physik.uni
