The effects of uncertainties in the structure of the superficial layers of the Sun, such as the helium abundance, opacity and equation of state, on the p-mode...

In recent years there has been some progress towards detecting solar-like oscillations in stars. The goal of this challenging project is to analyse frequency...

The influence of the upper layers of a star on p-mode frequencies can be described asymptotically by means of a phase function, which depends essentially only...

Frequencies of solar acoustic oscillations can be analyzed asymptotically in terms of a function determined by the sound speed in the bulk of the sun and a...

We introduce a method to infer the vertical distribution of stars in the Milky Way using a Poisson likelihood function, with a view to applying our method to...

We use Gaia photometry and astrometry to estimate the vertical spatial structure of the Milky Way at the Solar radius, formally accounting for sample...

M87 has been identified as a displaced supermassive black hole (SMBH) candidate. We investigated this possibility by a temporal analysis of 12 adaptive-optics...

The Photodetector Array Camera and Spectrometer (PACS) is one of the three science instruments on ESA's far infrared and submillimetre observatory. It employs...

Isolated galaxies are important because they probe the lowest density regimes inhabited by galaxies. We define a sample of 36 nearby isolated early-type...
