On the lack of stellar bars in Coma dwarf galaxies
J. Mendez-Abreu, R. Sanchez-Janssen, J. A. L. Aguerri
We present a study of the bar fraction in the Coma cluster galaxies based on a sample of ~190 galaxies selected from the SDSS-DR6 and observed with the Hubble Space Telescope (HST)…
Thin discs, thick dwarfs, and the importance of feedback effects
R. Sánchez-Janssen, J. Méndez-Abreu, J. A. L. Aguerri
We investigate the role of stellar mass in shaping the intrinsic thickness of faint systems by determining the probability distribution of apparent axis ratios for two different sa…
A Study of Catalogued Nearby Galaxy Clusters in the SDSS-DR4. II. Cluster Substructure
J. Alfonso L. Aguerri, Ruben Sanchez-Janssen
According to the current cosmological paradigm, large scale structures form hierarchically in the Universe. Clusters of galaxies grow through a continuous accretion of mass. Nevert…
Thin discs, thick dwarfs and the effects of stellar feedback
R. Sanchez-Janssen, J. Mendez-Abreu, J. A. L. Aguerri
We investigate the role of stellar mass in shaping the intrinsic thickness of galaxy discs by determining the probability distribution of apparent axis ratios (b/a) for two differe…
Which galaxies host bars and disks? A study of the Coma cluster
J. Mendez-Abreu, R. Sanchez-Janssen, J. A. L. Aguerri
We present a study of the bar fraction in the Coma cluster galaxies based on a sample of galaxies selected from the Sloan Digital Sky Survey Data Release 6 (SDSS-DR6) an…
