| Abstract: |
We study the spiral pattern in the inner 6.5 arcsec (1arcsec ≅265pc) of the Seyfert 2 nucleus of NGC1241. GEMINI-N K and J bands, as well as HST Paα and (V+R) ones are analysed through 2-D and 1-D Fourier techniques. A small (≅ 500 pc) long bar surrouded by a r = 700pc ring, both emitting in Paα are found. A CR at about r = 350pc is also determined, which lead to a pattern speed of 230 km/sec. The NIR spiral structure is smoother than the optical one, as found in large scale patterns. Other interesting kinematical as well as morphological structures are discussed. |
