GMRT Observations of NGC 3079
We present new observations at three frequencies (326 MHz, 615 MHz, and 1281 MHz) of the radio lobe spiral galaxy, NGC 3079, using the Giant Metrewave Radio Telescope. These observations are consistent with previous data obtained at other telescopes and reveal the structure of the nuclear radio lobes in exquisite detail. In addition, new features are observed, some with HI counterparts, showing...
متن کاملVLBI imaging of OH absorption : The puzzle of the nuclear region of NGC 3079
Broad hydroxyl (OH) absorption-lines in the 1667 MHz and 1665 MHz transition towards the central region of NGC3079 have been observed at high resolution with the European VLBI Network (EVN). Velocity fields of two OH absorption components were resolved across the unresolved nuclear radio continuum of ∼ 10 parsecs. The velocity field of the OH absorption close to the systemic velocity shows rota...

15 صفحه اولThe obscured circumnuclear region of the outflow galaxy NGC 3079
Images of the central region of the almost edge-on Sc galaxy NGC 3079 in the J , H and K-bands and in the v = 1→0 S(1) line of molecular hydrogen are presented. The inner few kiloparsecs of NGC 3079 exhibit a large range of nearinfrared colours caused by varying contributions from direct and scattered stellar light, emission from hot dust and extinction gradients. Our results show that interpre...
متن کاملObservations of the Hα/radio Lobe Galaxy Ngc 3079: Gas Dynamics in a Weak Bar Potential and Central Massive Core
We present CO (1-0) observations in the central 4.5 kpc (1) of the Hα/Radio lobe galaxy NGC 3079 with the Nobeyama Millimeter Array. The molecular gas shows four components: a main disk, spiral arms, a nuclear disk, and a nuclear core. The main disk extends along the galaxy major axis. We detected its central 2 kpc radius, while its full extent is beyond our spatial coverage. Molecular gas is s...
