    Carbon and Oxygen Abundances from Recombination Lines in Low Metallicity H II Regions
    We have measured C II and O II recombination lines in several H II regions of low-metallicity dwarf galaxies. These objects show lower C/O ratios than H II...

    Carbon and oxygen abundances from recombination lines in low-metallicity star-forming galaxies. Implications for chemical evolution
    We present deep echelle spectrophotometry of the brightest emission-line knots of the star-forming galaxies He 2-10, Mrk 1271, NGC 3125, NGC 5408, POX 4, SDSS...

    Carbon and oxygen in H II regions of the Magellanic Clouds: abundance discrepancy and chemical evolution
    We present C and O abundances in the Magellanic Clouds derived from deep spectra of H II regions. The data have been taken with the Ultraviolet-Visual Echelle...

    Carbon, nitrogen, and oxygen abundance gradients in M101 and M31
    We present deep spectrophotometry of 18 H II regions in the nearby massive spiral galaxies M 101 and M 31. We have obtained direct determinations of electron...

    Caught in the act: cluster `k+a' galaxies as a link between spirals and S0s
    We use integral field spectroscopy of 13 disc galaxies in the cluster AC114 at z ˜ 0.31 in an attempt to disentangle the physical processes responsible for the...

    Caught in the act: the winds driven by supermassive black holes directly impact star formation
    Patricia Bessiere, a researcher at the Instituto de Astrofísica de Canarias (IAC), has led research which has used data from the KECK telescope in Hawaii to...

    CAVITY, Calar Alto Void Integral-field Treasury surveY and project extension
    We have learnt in the last decades that the majority of galaxies belong to high density regions interconnected in a sponge-like fashion. This large-scale...

    CAVITY: Calar Alto Void Integral-field Treasury surveY: I. First public data release
    The Calar Alto Void Integral-field Treasury surveY (CAVITY) is a legacy project aimed at characterising the population of galaxies inhabiting voids, which are...

    CCD Hα and R photometry of 334 galaxies (James+, 2004)
    Hα plus [NII] and R-band CCD photometry and derived parameters are presented for the full sample of 334 spiral and irregular galaxies. Galaxy distances are...
