  • A measurement of the radial anisotropy at a redshift z ≅ 0.8 that is consistent with the standard cosmological-constant model with low matter density and flat geometry is reported, although error bars are still too large to distinguish among alternative origins for the accelerated expansion.

  • Chemical abundances derived from infrared nebular lines reveal strongly depressed metallicities in interacting galaxies, suggesting that in luminous infrared galaxies chemical enrichment and stellar-mass growth take place through mergers, which drive these galaxies out of equilibrium.

  • A selected group of intermediate-redshift galaxies appear similar to primeval galaxies. Analysing spectra of these nearer analogues for chemical abundances and ionization levels gives an improved understanding of galaxies that are too faint to study well.
