This article presents an on-line tool (rttools.irap.omp.eu) and its accompanying software ressources for the numerical solution of basic radiation transfer out of local thermodynamic equilibrium (LTE)....
View ArticleParameter-space metric for all-sky semicoherent searches for...
The sensitivity of all-sky searches for gravitational-wave pulsars is primarily limited by the finite availability of computing resources. Semicoherent searches are a widely-used method of maximizing...

This paper describes the Polarization Spectroscopic Telescope Array (PolSTAR), a mission proposed to NASA's 2014 Small Explorer (SMEX) announcement of opportunity. PolSTAR measures the linear...
View ArticleOff-disk straylight measurements for the Swedish 1-meter Solar Telescope
Context. Accurate photometry with ground based solar telescopes requires characterization of straylight. Scattering in Earth's atmosphere and in the telescope optics are potentially significant sources...

Modern radio telescopes are favoring densely packed array layouts consisting of large numbers of antennas ($N_\textrm{a}\gtrsim 1000$). Since the complexity of traditional correlators scales as...
View ArticleA Statistical Definition of Image Resolution Based on the Correlation of Pixels
Resolution, usually defined by the Rayleigh criterion or the Full Width at Half Maximum of a Point Spread Function, is a basic property of an image. Here, we present a new statistical definition of...

We demonstrate that it is possible to measure metallicity from the SDSS five-band photometry to better than 0.1 dex using supervised machine learning algorithms. Using spectroscopic estimates of...
View ArticleVersatile Directional Searches for Gravitational Waves with Pulsar Timing Arrays
By regularly monitoring the most stable millisecond pulsars over many years, pulsar timing arrays (PTAs) are positioned to detect and study correlations in the timing behaviour of those pulsars....
