Artificial Neural Networks as a Tool for Galaxy Classification
Ofer Lahav
We describe an Artificial Neural Network (ANN) approach to classification of galaxy images and spectra. ANNs can replicate the classification of galaxy images by a human expert to…
Probing Density Fluctuations at Low and High Redshift
Ofer Lahav
We discuss cosmological inference from galaxy surveys at low and high redshifts. Studies of optical and IRAS redshift surveys with median redshift yield measur…
Summary Talk: Multi-Wavelength Sky Surveys (IAU179)
Ofer Lahav
The summary talk of IAU179 'New Horizons from Multi-Wavelengths Sky Surveys', held in Baltimore in August 1996. First I summarize the highlights in different wavelengths as describ…
Present and Future Galaxy Redshift Surveys: ORS, DOGS and 2dF
Ofer Lahav
Three galaxy redshifts surveys and their analyses are discussed. (i) The recently completed Optical Redshift Survey (ORS) includes galaxies larger than 1.9 arcmin and/or brighter t…
