The ability of any Machine Learning method to classify the spectra of galaxies depending on the properties of the stellar component rests on the information...
The entropy of galaxy spectra: how much information is encoded?
The inverse problem of extracting the stellar population content of galaxy spectra is analysed here from a basic standpoint based on information theory. By...
The ESPRESSO transmission spectrum of HD189733 b: Extracting the planetary sodium and lithium signatures amid stellar contamination
Context. While transmission spectroscopy has allowed us to detect many atomic and molecular species in exoplanet atmospheres, the improvement in resolution and...
The evolution of the binary population in globular clusters: a full analytical computation
I present a simplified analytical model that simulates the evolution of the binary population in a dynamically evolving globular cluster. A number of...
The First Billion Years project: proto-galaxies reionizing the Universe
The contribution of stars in galaxies to cosmic reionization depends on the star formation history in the Universe, the abundance of galaxies during...
The First Billion Years project: the escape fraction of ionizing photons in the epoch of reionization
Protogalaxies forming in low-mass dark matter haloes are thought to provide the majority of ionizing photons needed to reionize the Universe, due to their high...
The First Billion Years simulation project. Galactic outflows and metal enrichment
The First Billion Years is one of the largest and most comprehensive cosmological, hydrodynamical simulation of the early Universe to date. It studies the...
The first release of data from the Herschel ATLAS: the SPIRE images
We have reduced the data taken with the Spectral and Photometric Imaging Receiver (SPIRE) photometer on board the Herschel Space Observatory in the Science...
