Galaxy cluster mergers are energetic events, where the shock front can reach temperatures of tens of keV. AS0592, located at
Ram pressure is directly related to the local density a galaxy interacts with, actively stripping its gas and forming the distinctive trails seen in jellyfish galaxies. Sloshing spirals are a common phenomenon observed in clusters that present significant density and temperature discontinuities that may impact the evolution of jellyfish galaxies crossing them. We aim to quantify how crossing...
Cosmological simulations, such as IllustrisTNG, are widely used to study the formation and evolution of galaxies on different scales, using parameters and physical models with a high degree of detail. However, the direct comparison of the results from N-body and smoothed particle hydrodynamics simulations with data from observational astronomy is not a straightforward step, presenting...
Obsevational data constraints from the eROSITA mission have estimated X-ray surface brightness profile ranges of the gas in the circumgalactic medium (CGM) in M31-like and Milky Way-like galaxies. Temperatures and gas density from similar galaxies in the Illustris TNG simulation have also been characterized. During a galactic interaction, it is possible that the presence of a CGM may affect...
Galaxy clusters are the universe's largest bound structures, and their use as a cosmological probe depends on their mass estimates, which cannot be measured directly. One of the most promising mass proxies is the surface mass density and related quantities (such as the reduced shear) from gravitational weak lensing. Its theoretical modeling depends on the halo mass density profile, which is...
