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 کاملThe complete submillimetre spectrum of NGC 891
Submillimetre maps of NGC 891 have been obtained with the PRONAOS balloonborne telescope and with the ISOPHOT instrument on board the ISO satellite. In this article, we also gather data from IRAS and SCUBA to present the complete submillimetre spectrum of this nearby edge-on spiral galaxy. We derive submillimetre emission profiles along the major axis. The modified blackbody fits, assuming a si...
متن کامل5 X - ray Bright QSO ’ s around NGC 3079
NGC 3079 is a very active, disturbed galaxy which has been observed to have X-ray and radio ejections from it as well as an optical superbubble along its minor axis. Here we show that the brightest X-ray sources within about 40 arcmin are in large excess of background values. The X-ray sources are identified as quasars and AGN's which are aligned and spaced across the Seyfert nucleus to a degre...
متن کاملThe 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 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...
