Cold dust in the giant barred galaxy NGC 1365
Constraining the physcial properties of dust requires observations at submm wavelengths. This will provide important insight into the gas content of galaxies. We mapped NGC 1365 at 870 μm with LABOCA, the Large APEX Bolometer Camera, allowing us to probe the central mass concentration as well as the rate at which the gas flows to the center. We obtained the dust physical properties both globall...
متن کاملMagnetic fields in barred galaxies . IV . NGC 1097 and NGC 1365
We present λ3.5 cm and λ6.2 cm radio continuum maps in total and polarized intensity of the barred galaxies NGC 1097 (at 2 ′′ –15 ′′ resolution) and NGC 1365 (at 9 ′′ –25 ′′ resolution). A previously unknown radio galaxy southwest of NGC 1097 is reported. Apart from a smooth faint envelope and a bright central region, both galaxies exhibit radio ridges roughly overlapping with the massive dust ...
متن کاملThe Mass Inflow Rate in the Barred Galaxy NGC 1530
Mass inflow in barred galaxies has been invoked to account for a wide variety of phenomena, but until now direct evidence for inflow has been lacking. We present Fabry-Perot Hα observations of the barred spiral galaxy NGC 1530 from which we determine velocities of the ionized gas for the entire region swept by the bar. We compare the velocity field to models of gas flow in barred spirals and sh...
متن کاملA counterrotating central component in the barred galaxy NGC 5728
We present a detailed study of the stellar kinematics in the barred galaxy NGC 5728 based on I-band photometry and long-slit spectroscopic observations in the region of the near-IR Ca II triplet. The analysis of the stellar line-of-sight velocity distribution (LOSVD) has revealed, in the central regions of the bar, the presence of a cold (v/σ ∼2.5) prograde S-shaped velocity component that coex...
متن کاملMass distribution and kinematics of the barred galaxy NGC 2336
For the intermediate-type barred galaxy NGC 2336 stationary models are constructed which reproduce in a consistent manner the observed distribution of the luminous matter and the observed gas kinematics in those regions affected by the bar. We present 2D fits to the observed NIR-band lumi-nosity distribution that consist of three components: a bulge, a bar, and a disk. The brightness distributi...
