Characterization of Orbits in Bars in Disc Galaxies Using Fourier Frequencies
A. Silva-Castro, I. Puerari, D. Valencia-Enríquez
Bars are among the most prominent dynamical structures in disc galaxies, yet their long-term evolution and the orbital families that sustain them remain only partially understood.…
Peculiar galaxies I: A Catalog of Polar-Ring Galaxies from the TNG50 Simulation
Josué G. López-Castillo, Manuel Zamora-Avilés, Gilberto C. Gómez +2
The hydrodynamic cosmological simulation, TNG50, is employed to conduct an analysis of multi-spin galaxies that exhibit ringed structures composed of gas and stars that orbit nearl…
Ferrers bar response models: a grid calculation for Galactic models
A. Silva-Castro, I. Puerari
This study numerically investigates the dynamics of barred spiral galaxies using 3D Ferrers bar response models. A total of 708 models were analyzed, incorporating variations in th…
The cluster initial mass function of the M82 disk Super Star Clusters
Bolivia Cuevas-Otahola, Divakara Mayya, Jesus Arriaga-Hernandez +2
The presence of a population of a large number (400) of almost coeval (100--300 Myr) super star clusters (SSCs) in the disk of M82 offers an opportunity to construct the Clus…
Orbital Structure Evolution in Self-Consistent N-body Simulations
Diego Valencia-Enríquez, Ivânio Puerari, Leonardo Chaves-Velasquez
The bar structure in disk galaxies models is formed by different families of orbits; however, it is not clear how these families of orbits support the bar throughout its secular ev…
Colour jumps across the spiral arms of Hubble Ultra Deep Field galaxies
Eric E. Martínez-García, Rosa A. González-Lópezlira, Ivânio Puerari
We have measured, at various wavelengths, the spiral arm pitch angles of a sample of distant spiral galaxies from the Hubble Space Telescope eXtreme Deep Field (XDF). According to…
