Photometric and Morphological Analysis of Fornax Galaxies through S-PLUS
A. V. Smith Castelli, A. R. Lopes, A. Cortesi +10
The photometric and morphological analysis of galaxies in clusters provides invaluable information regarding the evolutionary stage of the cluster itself. In addition, it helps to…
Spontaneous formation of double bars in dark matter dominated galaxies
Kanak Saha, Witold Maciejewski
Although nearly one-third of barred galaxies host an inner, secondary bar, the formation and evolution of double barred galaxies remain unclear. We show here an example model of a…
Spinning dark matter halos promote bar formation
Kanak Saha, Thorsten Naab
Stellar bars are the most common non-axisymmetric structures in galaxies and their impact on the evolution of disc galaxies at all cosmological times can be significant. Classical…
Secular evolution and cylindrical rotation in boxy/peanut bulges: impact of initially rotating classical bulges
Kanak Saha, Ortwin Gerhard
Boxy/peanut bulges are believed to originate from galactic discs through secular processes. A little explored question is how this evolution would be modified if the initial disc w…
Meridional tilt of the stellar velocity ellipsoid during bar buckling instability
Kanak Saha, Daniel Pfenniger, Ronald E. Taam
The structure and evolution of the stellar velocity ellipsoid plays an important role in shaping galaxies undergoing bar driven secular evolution and the eventual formation of a bo…
Spin-up of low mass classical bulges in barred galaxies
Kanak Saha, Inma Martinez-Valpuesta, Ortwin Gerhard
Secular evolution is one of the key routes through which galaxies evolve along the Hubble sequence. Not only the disk undergoes morphological and kinematic changes, but also a pree…
