<i>Planck</i> 2018 results

We present cosmological parameter results from the final full-mission Planck measurements of the cosmic microwave background (CMB) anisotropies, combining information from the t...

<i>Planck</i>2015 results

We present results based on full-mission Planck observations of temperature and polarization anisotropies of the CMB. These data are consistent with the six-parameter inflationa...

Stellar population synthesis at the resolution of 2003

We present a new model for computing the spectral evolution of stellar populations at ages between 100,000 yr and 20 Gyr at a resolution of 3 A across the whole wavelength range...

A Universal Density Profile from Hierarchical Clustering

We use high-resolution N-body simulations to study the equilibrium density profiles of dark matter halos in hierarchically clustering universes. We find that all such profiles h...

The Chemical Composition of the Sun

The solar chemical composition is an important ingredient in our understanding of the formation, structure, and evolution of both the Sun and our Solar System. Furthermore, it i...

Evolutionary models for low-mass stars and brown dwarfs: Uncertainties and limits at very young ages

We analyse pre-Main Sequence evolutionary tracks for low mass stars with masses $m \, \le \, 1.4 \, M_\odot$ based on the Baraffe et al. ([CITE]) input physics. We also extend t...

Spin-ordering in a planar classical Heisenberg model

Star formation, metallicity and dust properties derived from the StromloAPM galaxy survey spectra

We have derived star formation rates (SFRs), gas-phase oxygen abundances and effective dust absorption optical depths for a sample of galaxies drawn from the Stromlo—APM redshif...
