    The CARMENES search for exoplanets around M dwarfs: Magnesium and silicon abundances of K7–M5.5 stars
    We present the abundances of magnesium (Mg) and silicon (Si) for 314 dwarf stars with spectral types in the interval K7.0–M5.5 (T eff range ≈ 4200–3050 K)...

    The CARMENES search for exoplanets around M dwarfs: The impact of rotation and magnetic fields on the radial velocity jitter in cool stars
    Context. Radial velocity (RV) jitter represents an intrinsic limitation on the precision of Doppler searches for exoplanets that can originate from both...

    The CARMENES search for exoplanets around M dwarfs: Understanding the wavelength dependence of radial velocity measurements
    Context. Current exoplanet surveys are focused on detecting small exoplanets orbiting in the liquid-water habitable zones of their host stars. Despite recent...

    The central parsecs of active galactic nuclei: challenges to the torus
    Type 2 active galactic nuclei (AGN) are by definition nuclei in which the broad-line region and continuum light are hidden at optical/UV wavelengths by dust...
