How Barred is the NIR Nearby Universe? An analysis using 2MASS
K. Menendez-Delmestre, K. Sheth, N. Scoville +4
We determine a firm lower limit to the bar fraction of 0.58 in the nearby universe using J+H+Ks-band images for 134 spirals from 2MASS. With a mean deprojected semi-major axis of 5…
Using Bars As Signposts of Galaxy Evolution at High and Low Redshifts
K. Sheth, K. Menendez-Delmestre, N. Scoville +5
An analysis of the NICMOS Deep Field shows that there is no evidence of a decline in the bar fraction beyond z~0.7, as previously claimed; both bandshifting and spatial resolution…
Dust penetrated arm classes: insight from rising and falling rotation curves
Marc S. Seigar, David L. Block, Ivanio Puerari
We present near-infrared K-band images of 15 galaxies. We have performed a Fourier analysis on the spiral structure of these galaxies in order to determine their pitch angles and d…
Gravitational bar and spiral arm torques from K_s-band observations and implications for the pattern speeds
D. L. Block, R. Buta, J. H. Knapen +3
We have obtained deep near-infrared K_s-band William Herschel Telescope observations of a sample of 15 nearby spiral galaxies having a range of Hubble types and apparent bar streng…
