Bars are ellipsoidal-like structures that appears in the inner regions of a large fraction of discs of galaxies. Bars universal features present at all galactic...
Bar pattern speeds in CALIFA galaxies: ultrafast bars or too long bars?
More than 10% of the barred galaxies with a direct measurement of bar pattern speed host a bar rotating extremely fast. These bars are generally defined as...
Using the gravitational torque indicator Qb, we derive the distribution of bar strengths for a sample of early-type disk galaxies. The sample is part of the...
Bar Strengths in Galaxies as Measured from INGRID Images
We describe results from our study of a sample of spiral galaxies of a wide range of Hubble types on the basis of near-IR imaging obtained with INGRID on the...
Bar-Driven Disk Evolution: Grand-Design Nuclear Spirals
Through observations and modeling, we demonstrate how the recently discovered large-scale bar in NGC 5248 generates spiral structure that continues from 10 kpc...
Bar-Driven Galaxy Evolution at Intermediate Redshifts
Non-axisymmetric features such as bars drive the dynamical and secular evolution of disk galaxies by exerting gravitational torques which redistribute mass and...
Bar-driven Spiral Structure: Statistical Study of Nearby Galaxies in OSUBSGS and NIRS0S Samples
We use the OSUBSGS (Ohio State University Bright Spiral Galaxy Survey, Eskridge et al. 2002) and NIRS0S (Near-IR S0 Survey, Laurikainen et al. 2005) data to...
We know from near-infrared imaging that bars are present in more than three quarters of local disk galaxies. Several studies have recently led to the conclusion...
We use ACS data from the HST Treasury survey of the Coma cluster (z˜0.02) to study the properties of barred galaxies in the Coma core, the densest environment...
