GEMINI + GMOS and Chandra emission-line spectroscopy reveal that the Fanaroff-Riley II radio-source J133658.3- 295105 is a local object behind the barred-spiral galaxy M83 that is projected onto the galaxy?s disk at about 60" from the galaxy?s optica

Two-dimensional kinematics of the central region of M 83 (NGC 5236) were obtained through three-dimensional NIR spectroscopy with the Gemini South telescope. The spatial region covered by the integral field unit (∼ 5 ×13 or∼ 90×240 pc) was cent

Context. Bright knots along arms are observed in K-band images of many grand-design spiral galaxies. They are identified as young starforming complexes using K-band spectra which show strong Brγ emission. Their alignment with spiral arms and ages

We present Gemini optical imaging and spectroscopy of the radio source J 133658.3–295105. This source has been suggested to be the core of an FR II radio source with two detected lobes. J 133658.3–295105 and its lobes are aligned with the optical

We observationally investigate the properties of disk galaxies undergoing minor merger or capture events. In this context, the properties of two double-nucleus candidate galaxies, ESO 381–IG23 andMCG 3-35-14, are analyzed. Both are disk-dominated S

Context. Many grand design spiral galaxies show strings of bright knots along their arms on near-infrared K-band images. The alignment of such knots suggests a relation to the spiral pattern and possibly to a large-scale, star-forming front associate

We studied the spiral pattern in the inner 6".5 (1" = 257 pc) central regions of the interacting active nucleus galaxy NGC 1241 using Gemini North Telescope high-resolution Ks- and J-band images and Hubble Space Telescope (HST) Paα and H- and (V+R)-
