Dynamical Simulations of NGC 2523 and NGC 4245
P. Treuthardt, H. Salo, R. Buta
We present dynamical simulations of NGC 2523 and NGC 4245, two barred galaxies (types SB(r)b and SB(r)0/a, respectively) with prominent inner rings. Our goal is to estimate the bar…
Model-based pattern speed estimates for 38 barred galaxies
P. Rautiainen, H. Salo, E. Laurikainen
We have modelled 38 barred galaxies by using near-IR and optical data from the Ohio State University Bright Spiral Galaxy Survey. We constructed the gravitational potentials of the…
Comparison of bar strengths in optical and near-infrared for the OSUBSGS sample
T. Speltincx, E. Laurikainen, H. Salo
We use a gravitational bar torque method to compare bar strengths (the maximum tangential force normalized by radial force) in B and H-band images of 152 galaxies from the Ohio Sta…
Properties of Bars and Bulges in the Hubble Sequence
E. Laurikainen, H. Salo, R. Buta +1
Properties of bars and bulges in the Hubble sequence are discussed, based on the analysis of 216 disk galaxies (S0s and spirals from NIRS0S and OSUBGS surveys, respectively). For t…
