    A lower bound on intergalactic magnetic fields from time variability of 1ES 0229+200 from MAGIC and Fermi/LAT observations
    Context. Extended and delayed emission around distant TeV sources induced by the effects of propagation of γ ray s through the intergalactic medium can be used...
  • Publication
    A lower limit to the accretion disc radius in the low-luminosity AGNNGC 1052 derived from high-angular resolution data
    We investigate the central sub-arcsec region of the low-luminosity active galactic nucleusNGC 1052, using a high-angular resolution data set that covers 10...
  • Publication
    A machine learning approach to galaxy properties: joint redshift-stellar mass probability distributions with Random Forest
    We demonstrate that highly accurate joint redshift-stellar mass probability distribution functions (PDFs) can be obtained using the Random Forest (RF) machine...
  • Publication
    A mean redshift of 2.8 for Swift gamma-ray bursts
    The exceptionally high luminosities of gamma-ray bursts (GRBs), gradually emerging as extremely useful probes of star formation, make them promising tools for...
  • Publication
    A measurement of galaxy halo mass from the surrounding H I Lyα absorption
    We measure the dark matter halo masses of ≈ 2.36 UV colour-selected star-forming galaxies by matching the observed median H I Lyα absorption around them, as...
  • Publication
    A mid-infrared spectroscopic atlas of local active galactic nuclei on sub-arcsecond resolution using GTC/CanariCam
    We present an atlas of mid-infrared (mid-IR) ˜ 7.5-13 μm spectra of 45 local active galactic nuclei (AGN) obtained with CanariCam on the 10.4 m Gran Telescopio...
  • Publication
    A mid-infrared statistical investigation of clumpy torus model predictions
    We present new calculations of the Clumpy AGN Tori in a 3D geometry (CAT3D) clumpy torus models, which now include a more physical dust sublimation model as...
  • Publication
    A mid-infrared view of the inner parsecs of the Seyfert galaxy Mrk 1066 using CanariCam/GTC
    We present mid-infrared (MIR) imaging and spectroscopic data of the Seyfert 2 galaxy Mrk 1066 obtained with CanariCam (CC) on the 10.4-m Gran Telescopio...
  • Publication
    A minor merger origin for stellar inner discs and rings in spiral galaxies
    Context. Observations have shown that inner discs and rings (IDs and IRs) are not preferably found in barred galaxies, which indicates that their formation may...
