Long-slit spectroscopy of starburst galaxies
The Astrophysical Journal, 1988 We present high-resolution, long-slit spectra of nine optically bright nuclear star-burst galaxies (SBGs) selected from the sample of Balzano from which we measure line strengths, line widths, and velocity profiles along the slit in the Hα, [N II], and [S II] emission lines.

Spectroscopy of Luminous Infrared Galaxies [PDF]
Symposium - International Astronomical Union, 1999 A review of recent optical and infrared spectroscopic results on luminous infrared galaxies is presented. The main emphasis is on the ultraluminous objects. Possible correlations with infrared luminosity are identified. These results are used to constrain the nature of the dominant energy source in luminous infrared galaxies, and to test whether these ...

Spectroscopy of the galaxy components of N and Seyfert galaxies [PDF]
Publications of the Astronomical Society of the Pacific, 1987 Nuclear and off-nuclear spectra of nine active galaxies are presented. The sample consists of four Seyfert galaxies, two N galaxies, one Seyfert radio galaxy, and one liner/Seyfert 2 galaxy. All of the objects show continuum emission off the nucleus. Four clearly show absorption features from a stellar population.

JHK Spectra of the z=2.39 Radio Galaxy 53W002 [PDF]
, 2001 We present low-resolution, near-IR JHK spectra of the weak z=2.39 radio galaxy 53W002, obtained with the OH-airglow Suppressor spectrograph (OHS) and Cooled Infrared Spectrograph and Camera for OHS (CISCO) on the Subaru Telescope.

Slit and integral-field optical spectroscopy of the enigmatic quasar HE0450-2958 [PDF]
, 2008 Interest in the quasar HE0450-2958 arose following the publication of the non-detection of its expected massive host, leading to various interpretations. This article investigates the gaseous and stellar contents of the system through additional VLT/FORS

Spectroscopy of Three SBS Galaxies [PDF]
Symposium - International Astronomical Union, 1996 Three galaxies from Second Byurakan Sky Survey have been studied. The spectra of these galaxies were obtained at 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences. For these objects line widths and emission line ratios were measured and ionization mechanism and chemical abundances were determined.
