Quantifying the unwinding due to ram pressure stripping in simulated galaxies
Rubens E. G. Machado, Caroline F. O. Grinberg, Elvis A. Mello-Terencio
Galaxies moving through the gas of the intracluster medium (ICM) experience ram pressure stripping, which can leave behind a gas tail. When a disk galaxy receives the wind edge-on,…
Investigating the clumpy star formation in an interacting dwarf irregular galaxy
Augusto E. Lassen, Ana L. Chies-Santos, Rogerio Riffel +9
Clumpy morphologies are more frequent in distant and low-mass star-forming galaxies. Therefore the less numerous nearby galaxies presenting kpc-sized clumps represent unique labora…
Accuracy of analytic potentials for orbits of satellites around a Milky Way-like galaxy: comparison with -body simulations
Rubens E. G. Machado, Giovanni C. Tauil, Nicholas Schweder-Souza
To study the orbits of satellites, a galaxy could be modelled either by means of a static gravitational potential, or by live -body particles. Analytic potentials allow for fast…
Bar properties as a function of wavelength in TNG50: analysis of mock images
Gustavo F. Gonçalves, Rubens E. G. Machado, Karín Menéndez-Delmestre +1
Recent studies used TNG50 galaxies to study bar formation, evolution, and properties like length, strength, and pattern speed. In simulations, these are typically derived from part…
