Aims. We investigate the influence of the interstellar medium (ISM) on debris discs using a statistical approach. We probe the effect of the ISM on debris disc...
Environmental effects on the bright end of the galaxy luminosity function in galaxy clusters
Context. The dependence of the luminosity function (LF) of cluster galaxies on the evolutionary state of the parent cluster is still an open question, in...
Environments of galaxies in groups within the supercluster-void network
Context. The majority of all galaxies reside in groups of fewer than 50 member galaxies. These groups are distributed in various large-scale environments from...
Environments of nearby quasars in Sloan Digital Sky Survey
Context: For the first time, spectroscopic galaxy redshift surveys are enabling galaxies to be studied with the nearest quasars. This allows the dependence of...
EROS 2 proper motion survey: a field brown dwarf, and an L dwarf companion to LHS 102
We report the discovery of two L dwarfs (the new spectral class defined for dwarfs cooler than the M type) in a two-epoch CCD proper motion survey of 413 square...
EROs found behind lensing clusters. I. Stellar populations and dust properties of optical dropout EROs and comparison with related objects
Context: On the nature, redshift, stellar populations and dust properties of optically faint or non-detected extremely red objects. Aims: Determining the nature...
EROs found behind lensing clusters. II. Empirical properties, classification, and SED modelling based on multi-wavelength observations
Aims:We study the properties and nature of extremely red galaxies (ERO, R-K≥5.6) found behind two lensing clusters and compare them with other known galaxy...
