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.

    The stellar spectral features of nearby galaxies in the near infrared: tracers of thermally pulsing asymptotic giant branch stars?
    We analyse the stellar absorption features in high signal-to-noise ratio (S/N) near-infrared (NIR) spectra of the nuclear region of 12 nearby galaxies, mostly...
