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.

    Central star formation and metallicity in CALIFA interacting galaxies
    We use optical integral-field spectroscopic (IFS) data from 103 nearby galaxies at different stages of the merging event, from close pairs to merger remnants...

    Circumnuclear Star Formation and AGN Activity: Clues from Surface Brightness Radial Profile of PAHs and [{\rm{S}}\,{\rm{IV}}]
    We studied the circumnuclear mid-IR emission in a sample of 19 local active galactic nuclei (AGNs) with high spatial resolution spectra using T-ReCS (Gemini)...

    Clear evidence for the early triggering of a luminous quasar-like active galactic nuclei in a major, gas-rich merger
    We present deep, intermediate resolution, long-slit Gemini GMOS-S optical spectra of the Sloan Digital Sky Survey (SDSS) type II quasar J002531-104022, which is...

    CO in the ALMA Radio-source Catalogue (ARC): The molecular gas content of radio galaxies as a function of redshift
    To evaluate the role of radio activity in galaxy evolution, we designed a large archival CO survey of radio galaxies (RGs) to determine their molecular gas...

    CO kinematics unveil outflows plausibly driven by a young jet in the gigahertz peaked radio core of NGC 6328
    We report the detection of outflowing molecular gas in the center of the nearby (z = 0.014) massive radio galaxy NGC 6328. The radio core of the galaxy, PKS...
  • Publication
    Cold molecular gas and PAH emission in the nuclear and circumnuclear regions of Seyfert galaxies
    We investigate the relation between the detection of the 11.3 μm polycyclic aromatic hydrocarbon (PAH) feature in the nuclear (∼24-230 pc) regions of 22 nearby...

    Comparative internal kinematics of the H II regions in interacting and isolated galaxies: implications for massive star formation modes
    We have observed 12 interacting galaxy pairs using the Fabry-Perot interferometer GH αFaS (Galaxy H α Fabry-Perot system) on the 4.2-m William Herschel...

    Complex AGN feedback in the Teacup galaxy. A powerful ionised galactic outflow, jet-ISM interaction, and evidence for AGN-triggered star formation in a giant bubble
    Context. The z ∼ 0.1 type-2 QSO J1430+1339, known as the " Teacup", is a complex galaxy showing a loop of ionised gas ∼10 kpc in diameter, co-spatial radio...

    Composite bulges - II. Classical bulges and nuclear discs in barred galaxies: the contrasting cases of NGC 4608 and NGC 4643
    We present detailed morphological, photometric, and stellar-kinematic analyses of the central regions of two massive, early-type barred galaxies with nearly...
