Radio Observations of the Hubble Deep Field South Region IV: Optical Properties of the Faint Radio Population
M. T. Huynh, C. A. Jackson, R. P. Norris +1
The Australia Telescope Hubble Deep Field-South (ATHDFS) survey of the Hubble Deep Field South reaches sensitivities of ~10 miceoJyJy at 1.4, 2.5, 5.2 and 8.7 GHz, making the ATHDF…
Spectral Classification of Quasars in the Sloan Digital Sky Survey: Eigenspectra; Redshift and Luminosity Effects
C. W. Yip, A. J. Connolly, D. E. Vanden Berk +10
We study 16,707 quasar spectra from the SDSS using the Karhunen-Loève (KL) transform (or Principal Component Analysis, PCA). The quasar eigenspectra of the full catalog reveal the…
Distributions of Galaxy Spectral Types in the Sloan Digital Sky Survey
Ching-Wa Yip, Andrew Connolly, Alex Szalay +12
We perform an objective classification of 170,000 galaxy spectra in the Sloan Digital Sky Survey (SDSS) using the Karhunen-Loève (KL) transform. With about one-sixth of the total s…
A new source detection algorithm using FDR
A. M. Hopkins, C. J. Miller, A. J. Connolly +3
The False Discovery Rate (FDR) method has recently been described by Miller et al (2001), along with several examples of astrophysical applications. FDR is a new statistical proced…
Global star formation history: A Local Group perspective
A. M. Hopkins, M. J. Irwin, A. J. Connolly
The global star formation rate (SFR) density is estimated from the star formation histories (SFHs) of Local Group galaxies. This is found to be broadly consistent with estimates of…
Cold gas in elliptical galaxies
A. Georgakakis, A. M. Hopkins, A. Caulton +3
We explore the evolution of the cold gas (molecular and neutral hydrogen) of elliptical galaxies and merger remnants ordered into a time sequence on the basis of spectroscopic age…
