Astrochemical models are important tools to interpret observations of molecular and atomic species in different environments. However, these models are time...
A fast version of the k-means classification algorithm for astronomical applications
Context. K-means is a clustering algorithm that has been used to classify large datasets in astronomical databases. It is an unsupervised method, able to cope...
A fast, very-high-energy γ-ray flare from BL Lacertae during a period of multi-wavelength activity in June 2015
The mechanisms producing fast variability of the γ-ray emission in active galactic nuclei (AGNs) are under debate. The MAGIC telescopes detected a fast, very...
A feasibility study on the photometric detection of quiescent black hole X-ray binaries
We investigate the feasibility of detecting quiescent black hole X-ray binaries using optical photometric techniques. To test this, we employ a combination of r...
A feather on the hat: tracing the giant stellar stream around the Sombrero galaxy
Recent evidence of extremely metal-rich stars found in the Sombrero galaxy (M104) halo suggests that this galaxy has undergone a recent major merger with a...
A few StePS forward in unveiling the complexity of galaxy evolution: light-weighted stellar ages of intermediate-redshift galaxies with WEAVE
Context. The upcoming new generation of optical spectrographs on four-meter-class telescopes, with their huge multiplexing capabilities, excellent spectral...
A first catalogue of automatically selected ultraviolet-excess sources from the UVEX survey
We present the first catalogue of point-source ultraviolet (UV)-excess sources selected from the UV-Excess Survey of the Northern Galactic Plane (UVEX). UVEX...
A First Glimpse Into the Far-IR Properties of High-z UV-selected galaxies: Herschel/PACS Observations of z ~ 3 LBGs
We present first insights into the far-IR properties for a sample of IRAC and MIPS 24 μm detected Lyman break galaxies (LBGs) at z ~ 3, as derived from...
