When galaxies cross cold fronts: wind tunnel simulations of ram pressure stripping
Elvis A. Mello-Terencio, Rubens E. G. Machado, Richards P. Albuquerque
Cluster collisions and mergers are among the most energetic phenomena in the low redshift Universe. These interactions disturb the intracluster medium creating regions with density…
The contribution of the color space in LSST-like photometry for the selection of extragalactic globular cluster candidates
Nicholas Schweder-Souza, Ana L. Chies-Santos, Rafael S. de Souza +16
Globular clusters (GCs) are excellent tracers of their host galaxies' evolutionary histories. Traditional methods for identifying GCs in galaxies rely on cuts over photometric cata…
Bar properties as a function of wavelength in TNG50: analysis of mock images
Gustavo F. Gonçalves, Rubens E. G. Machado, KarÃn 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…
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…
