We present new weak-lensing observations of 1E 0657-558 (z= 0.296), a unique cluster
merger, that enable a direct detection of dark matter, independent of assumptions regarding …

We present an analysis of the host properties of 85 224 emission-line galaxies selected from
the Sloan Digital Sky Survey. We show that Seyferts and low-ionization narrow emission-line …

Abstract We analyse az< 0.1 galaxy sample from the Sloan Digital Sky Survey focusing on
the variation in the galaxy colour bimodality with stellar mass and projected neighbour …

We investigate the well-known correlations between the dynamical mass-to-light ratio (M/L)
and other global observables of elliptical (E) and lenticular (S0) galaxies. We construct two …

Using a large galaxy group catalogue constructed from the Sloan Digital Sky Survey Data
Release 2, we investigate the correlation between various galaxy properties and halo mass …

The relationship between galaxies and dark matter (DM) can be characterized by the halo
mass of the central galaxy and the fraction of galaxies that are satellites. Here, we present …

We present the evolution of the luminosity-size and stellar mass-size relations of luminous
(LV≳ 3.4× 10 10 h L☉) and massive (M*≳ 3× 10 10 h M☉) galaxies in the last~ 11 Gyr. We …

We characterize the mass-dependent evolution of more than 8000 galaxies using
spectroscopic redshifts from the DEEP2 Galaxy Redshift Survey in the range 0.4< z< 1.4 and …

Generally the gas metallicity in distant galaxies can only be inferred by using a few
prominent emission lines. Various theoretical models have been used to predict the …

Using integrated optical spectrophotometry for 412 star-forming galaxies at z~ 0, and fiber-
aperture spectrophotometry for 120,846 SDSS galaxies at z~ 0.1, we investigate the Hα …
