Context. Post-facto image restoration techniques are essential for improving the quality of ground-based astronomical observations, which are affected by...

We used the CLUMPY torus models and a Bayesian approach to fit the infrared spectral energy distributions and ground-based high angular resolution mid-infrared...

We present a statistical analysis of the properties of the obscuring material around active galactic nuclei (AGN). This study represents the first of its kind...

We characterize for the first time the torus properties of an ultra-hard X-ray (14-195 keV) volume-limited (DL 40 Mpc) sample of 24 Seyfert (Sy) galaxies...

Context: .Observational follow-up programmes for the characterization of ultra-luminous X-ray sources (ULXs) require the construction of clean samples of such...

Big Bear Solar Observatory is building the world's first global earthshine network to measure Earth's large-scale reflectance. Our first remote station was...

Accurate astronomical distance determination is crucial for all fields in astrophysics, from Galactic to cosmological scales. Despite, or perhaps because of...

We present long-slit spectra of the Seyfert 2 galaxy NGC 5252, covering the nucleus and part of the extranuclear emission-line region. All the regions sampled...

The discrepancies between b →s ℓ +ℓ - data and the corresponding Standard Model predictions constitute one of the most significant hints for new physics...
