The Parkes quarter-Jansky flat-spectrum sample 2. New Optical Spectra and Redshift Measurements
I. M. Hook, P. A. Shaver, C. A. Jackson +2
We present optical spectra and redshift measurements for 178 flat-spectrum objects from the Parkes quarter-Jansky flat-spectrum sample. These spectra were obtained in order to comp…
The Hubble Diagram of Type Ia Supernovae as a Function of Host Galaxy Morphology
M. Sullivan, R. S. Ellis, G. Aldering +41
(Abridged) We present new results on the Hubble diagram of distant type Ia supernovae (SNe Ia) segregated according to the type of host galaxy. This makes it possible to check earl…
The Type Ia Supernova 1999aw: a Probable 1999aa-like Event In a Low-Luminosity Host Galaxy
L. -G. Strolger, R. C. Smith, N. B. Suntzeff +39
SN 1999aw was discovered during the first campaign of the Nearby Galaxies Supernova Search (NGSS) project. This luminous, slow-declining (Delta m_{15} (B) = 0.81 \pm 0.03) Type Ia…
Discovery of Radio-loud Quasars with Redshifts above 4 from the PMN sample
I. M. Hook, R. G. McMahon, P. A. Shaver +1
We present results of a new, large survey for high-redshift radio-loud quasars, which targets quasars with z>4. The survey is based on the PMN and NVSS radio surveys, optically ide…
Integral Field Spectroscopy with the Gemini 8-m Telescopes
B. W. Miller, J. Turner, M. Takamiya +2
We give an overview of the current and future IFU capabilities on the Gemini 8-m telescopes. The telescopes are well-suited to integral field spectroscopy and both telescopes will…
The GMOS integral field unit: first integral field spectroscopy with an 8m telescope
Jeremy Allington-Smith, Graham Murray, Robert Content +8
The Gemini Multiobject Spectrograph (GMOS) installed on the Gemini-North telescope has a facility for integral field spectroscopy over the wavelength range 0.4-1.0um. GMOS is conve…
