Magnetic 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 کاملCold 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 کاملThe ROSAT view of NGC 1365 and the luminous highly variable off-nuclear X-ray source NGC 1365–X1
We present an X-ray spectral and spatial analysis of the composite starburst/Seyfert galaxy NGC1365. Excellent fits of the ROSAT PSPC spectrum are obtained by combining a soft thermal component with a hard powerlaw. The hard component may be either seen directly or can be explained by scattering of the AGN powerlaw at circumnuclear warm high-column-density gas. A compilation of the multi-wavele...
متن کاملA circumnuclear molecular torus in NGC 1365
The central region of NGC 1365 has been mapped in the J = 3 − 2 CO emission line with the 15 m SEST, which has a HPBW of 15′′ at the frequency of this transition. The observing grid has a 5′′-spacing in the inner and a 10′′-spacing in the outer region. A deconvolved map has been produced using the Maximum Entropy Method (MEM). A circumnuclear molecular torus with a radius of about 6. ′′5 is the...
متن کاملThe velocity field of the barred spiral galaxy NGC 1300 revisited ?
The re-reduction, described in Jörsäter & van Moorsel (1995), of NGC 1300 VLA H i observations, originally obtained by M. England, motivates a new analysis of the velocity field and rotation curve. Fitting tilted ring models to the H i velocity data, we find the new values for the orientation parameters of NGC 1300 to be PAlon = 267◦ ± 2◦ and i = 35◦ ± 5◦. Subsequently, the H i rotation curve i...
