We present a study of the properties of radial conformal Killing fields (RCKF) in conformally flat space-times, pointing out its interest in kinematical...
Confronting Dark Matter Models with Nearby Dwarf Irregular Galaxies
Dwarf irregular galaxies, due to their lower masses, relative isolation, and high-quality data availability, are ideal laboratories to test various models of...
Confronting hierarchical clustering models with observations of galaxy pairs
We investigate the star formation activity in galaxy pairs in chemical hydrodynamical simulations consistent with a Lambda-CDM scenario. A statistical analysis...
Connecting the central and global structure of early-type galaxies
A new empirical model that accurately describes the inner and outer light-profiles of early-type galaxies is presented. This model effectively unites the Sérsic...
Connecting the Properties of RR Lyrae Stars in the Milky Way and Andromeda with Local Group Dwarf Galaxies
In this new era of extensive variability surveys, classical pulsators such as RR Lyrae stars (RRLs) and Classical Cepheids play a crucial role. We focus our...
Tightly connect tubes used for the circulation of cryogenic fluids is a task that requires some thought and technical experience. ESO is intensively using...
Constellation-X will obtain for the first time high quality X-ray spectra for all classes of X-ray sources, over a wide range of luminosity and distance. It is...
