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.

    Differences between CO- and calcium triplet-derived velocity dispersions in spiral galaxies: evidence for central star formation?
    We examine the stellar velocity dispersions (σ) of a sample of 48 galaxies, 35 of which are spirals, from the Palomar nearby galaxy survey. It is known that for...

    Diffuse interstellar bands λ5780 and λ5797 in the Antennae Galaxy as seen by MUSE
    Context. Diffuse interstellar bands (DIBs) are faint spectral absorption features of unknown origin. Research on DIBs beyond the Local Group is very limited and...

    DIMMA -Automatic Differential Image Motion Monitor
    Improvement and modernisation of the seeing monitor, which was developed at the IAC and has been in regular use since 1995.

    Disc galaxies are still settling. Discovery of the smallest nuclear discs and their young stellar bars
    When galactic discs settle and become massive enough, they are able to form stellar bars. These non-axisymmetric structures induce shocks in the gas, causing it...

    Discovery of an old nova remnant in the Galactic globular cluster M 22
    A nova is a cataclysmic event on the surface of a white dwarf in a binary system that increases the overall brightness by several orders of magnitude. Although...

    Disk Galaxies Are Self-similar: The Universality of the H I-to-Halo Mass Ratio for Isolated Disks
    Observed scaling relations in galaxies between baryons and dark matter global properties are key to shed light on the process of galaxy formation and on the...

    Dissemination of scientific and technological capabilities, and socio-economic impact of the IAC
    One of IAC’s primary objectives is to improve its own scientific and technological capabilities. The promotion of these capacities, both nationally and...

    Do AGN triggering mechanisms vary with radio power? - I. Optical morphologies of radio-intermediate HERGs
    Active galactic nuclei (AGNs) with intermediate radio powers are capable of driving multiphase outflows in galaxy bulges, and are also more common than their...

    Do AGN triggering mechanisms vary with radio power? - II. The importance of mergers as a function of radio power and optical luminosity
    Investigation of the triggering mechanisms of radio active galactic nuclei (radio AGN) is important for improving our general understanding of galaxy evolution...
