I will describe the major scientific motivation and outline design concept for a new 2 degree field, 1000 fibre multi-object spectroscopy facility for the WHT...

Radar observation of near-Earth asteroids (NEAs) reveal the size, shape, spin characteristics of the population of small bodies near the Earth. Although...

In a framework where galaxies form hierarchically, extended stellar haloes are predicted to be an ubiquitous feature around Milky Way-like galaxies and to...

Understanding galaxy evolution requires understanding the impact of cosmic time, environment, mass, and halo growth at least, because likely a combination of...

Recent advances in 3D model atmospheres have led to a significant downward revision in photospheric heavy element abundance estimates for the Sun, especially...

Magnetic fields break through the solar surface in a hierarchy of magnetic elements ranging from Earth-sized sunspots down to tiny concentrations that are...

Spectroscopy is a powerful tool to unravel the nature of stellar bodies. For instance, spectra can be used to derive the temperature, gravity, and chemical...

The great energy source of ultraluminous infrared galaxies (ULIRGs) may be the accreting supermassive black holes of active galactic nuclei (AGNs) or intense...

The concordance model of cosmology with its constituents dark matter and dark Energy is an established description of some anomalous observations. However, a...
