Chemistry in the dIrr galaxy Leo A
We present chemical abundance determinations of two H II regions in the dwarf irregular (dIrr) galaxy Leo A from Gran Telescopio Canarias (GTC) Optical System...
Chemoarchaeological downsizing in a hierarchical universe: impact of a top-heavy IGIMF
We make use of a semi-analytical model of galaxy formation to investigate the origin of the observed correlation between [α/Fe] abundance ratios and stellar...
Chromospheric polarimetry through multiline observations of the 850 nm spectral region III: Chromospheric jets driven by twisted magnetic fields
We investigate the diagnostic potential of the spectral lines at 850 nm for understanding the magnetism of the lower atmosphere. For that purpose, we use a...
Chromospheric polarimetry through multiline observations of the 850-nm spectral region - II. A magnetic flux tube scenario
In this publication, we continue the work started in Quintero Noda et al., examining this time a numerical simulation of a magnetic flux tube concentration. Our...
CHRONOSTAR - II. Kinematic age and substructure of the Scorpius-Centaurus OB2 association
The nearest region of massive star formation - the Scorpius-Centaurus OB2 association (Sco-Cen) - is a local laboratory ideally suited to the study of a wide...
Circumgalactic medium of quasars: C IV absorption systems
We investigate the properties of circumgalactic gas in the halo of quasar (QSO) host galaxies from C IV absorption-line systems. We use the optical spectroscopy...
Circumnuclear kinematics in NGC 5248: the origin of nuclear spiral arms
We present for the first time a two-dimensional velocity field of the central region of the grand-design spiral galaxy NGC 5248, at 0.9-arcsec spatial...
Circumnuclear regions in barred spiral galaxies - I. Near-infrared imaging
We present subarcsecond-resolution, ground-based, near-infrared images of the central regions of a sample of 12 barred galaxies with circumnuclear star...
Circumstellar disc geometry constrained by infrared line fluxes
Lenorzer et al. introduce ratios of hydrogen infrared recombination lines as a diagnostic tool to constrain the spatial distribution and physical condition of...
