DOI: 10.1093/mnras/staa2866
Abstract: Bars are common in low-redshift disk galaxies, and hence quantifying their influence on their host is of importance to the field of galaxy evolution. We determine the stellar populations and star formation histories of 245… read more here.

DOI: 10.1093/mnras/stad1531
Abstract: In this paper we analyze a sample of 46 barred galaxies of MaNGA. Our goal is to investigate the stellar kinematics of these galaxies and obtain their rotation curves. Additionally, we aim to derive the… read more here.

DOI: 10.1093/mnras/stx2398
Abstract: The escape dynamics of the stars in a barred galaxy composed of a spherically symmetric central nucleus, a bar, a flat thin disk and a dark matter halo component is investigated by using a realistic… read more here.

DOI: 10.1093/mnras/sty2715
Abstract: The MaNGA project has obtained IFU data for several thousand nearby galaxies, including barred galaxies. With the two dimensional spectral and kinematic information provided by IFUs, we can measure the pattern speed of a barred… read more here.

DOI: 10.1093/mnras/stz3180
Abstract: We analyse the properties of strongly barred disc galaxies using the TNG100 simulation, a cosmological hydrodynamical realisation of the IllustrisTNG suite. We identify 270 disc galaxies at z = 0 in the stellar mass range… read more here.
