Staff from Instituto de Astrofisica de Canarias, Lund Observatory, Physics Department and Larmor Research Institute at Galway, and Tuorla Observatory is collaborating on studies for a 50 m optical and infrared telescope. The telescope concepts are based on the work on extremely large telescopes carried out during 1991-2000 at Lund Observatory, and

We present mid- and far-IR data from the CfA Seyfert sample, obtained with two instruments---ISOCAM and ISOPHOT---on board ISO. The spatial resolution of ISOCAM images allows us to separate the nuclear and extended contributions of the integrated emission. The improved spatial resolution of the ISOPHOT detectors allows us for the first time to

Our main goal is to review: 1) some physical mechanisms which form the observed structures in galactic disks; 2) the discovery of new galactic structures predicted earlier. Specifically in the first part of the paper we discuss some questions associated with spiral structure. The second part is devoted to the prediction and discovery of giant

We present a kinematical comparison of the HI and HII contents of the barred spiral galaxy NGC 3359. Non-circular motions are observed near the strong bar and the spiral arms of the galaxy as seen in the moment one and residual velocity field maps.

New ground based observing opportunities are becoming, or about to become, available to astronomers for QSO research. These, combined with state of the art focal plane instruments, provide unprecedented sensitivity for detecting faint surface brightness features. During the talk I will take the liberty of talking about one of these new large
