Lines of instrumentation: Visible instrumentation

Visible instrumentation

From its origins, the Instrumentation Division has participated in the construction of instrumentation to detect and analyze light in the visible range of the spectrum. Cameras, spectrographs, polarization analyzers, optical fibers fed systems, among others, have been designed, built, integrated and verified in our facilities.

    Spotting the differences between active and non-active twin galaxies on kpc-scales: a pilot study
    We present a pilot study aimed to identify large-scale galaxy properties that could play a role in activating a quiescent nucleus. To do so, we compare the...

    Stellar activity analysis of Barnard's Star: very slow rotation and evidence for long-term activity cycle
    The search for Earth-like planets around late-type stars using ultrastable spectrographs requires a very precise characterization of the stellar activity and...

    Stellar kinematics across the Hubble sequence in the CALIFA survey: general properties and aperture corrections
    We present the stellar kinematic maps of a large sample of galaxies from the integral-field spectroscopic survey CALIFA. The sample comprises 300 galaxies...

    Stellar populations and physical properties of starbursts in the antennae galaxy from self-consistent modelling of MUSE spectra
    We have modelled the stellar and nebular continua and emission-line intensity ratios of massive stellar populations in the Antennae galaxy using high resolution...

    STEPAR: an automatic code to infer stellar atmospheric parameters
    Context. STEPAR is an automatic code written in Python 3.X designed to compute the stellar atmospheric parameters Teff, log g, [Fe/H], and ξ of FGK-type stars...

    Strong lensing reveals jets in a sub-microJy radio-quiet quasar
    We present e-MERLIN and European VLBI Network observations which reveal unambiguous jet activity within radio-quiet quasar HS 0810+2554. With an intrinsic flux...

    Sub-arcsec mid-IR observations of NGC 1614: Nuclear star formation or an intrinsically X-ray weak AGN?
    We present new mid-infrared (mid-IR) N-band spectroscopy and Q-band photometry of the local luminous IR galaxy NGC 1614, one of the most extreme nearby...

    Survival of the Obscuring Torus in the Most Powerful Active Galactic Nuclei
    Dedicated searches generally find a decreasing fraction of obscured active galactic nuclei (AGN) with increasing AGN luminosity. This has often been interpreted...

    Synapses of active galactic nuclei:. Comparing X-ray and optical classifications using artificial neural networks
    Context. Many classes of active galactic nuclei (AGN) have been defined entirely through optical wavelengths, while the X-ray spectra have been very useful to...
