The intracluster light as a tracer of the total matter density distribution: a view from simulations
By using deep observations of clusters of galaxies, it has been recently found that the projected stellar mass density closely follows the projected total (dark...
The intriguing H I gas in NGC 5253: an infall of a diffuse, low-metallicity H I cloud?
We present new, deep H I line and 20-cm radio-continuum data of the very puzzling blue compact dwarf galaxy NGC 5253, obtained with the Australia Telescope...
The intrinsic alignment of red galaxies in DES Y1 redMaPPer galaxy clusters
Clusters of galaxies trace the most non-linear peaks in the cosmic density field. The weak gravitational lensing of background galaxies by clusters can allow us...
The intrinsic three-dimensional shape of galactic bars
We present the first statistical study on the intrinsic three-dimensional (3D) shape of a sample of 83 galactic bars extracted from the CALIFA survey. We use...
The ionized gas at the centre of IC 10: a possible localized chemical pollution by Wolf-Rayet stars
We present results from integral field spectroscopy with the Potsdam Multi-Aperture Spectrograph at the 3.5-m telescope at Calar Alto Observatory of the intense...
The ionizing radiation from massive stars and its impact on HII regions: results from modern model atmospheres
We present a detailed comparison of the ionizing spectral energy distributions (SEDs) predicted by four modern stellar atmosphere codes, TLUSTY, CMFGEN, WM...
The IPHAS catalogue of Hα emission-line sources in the northern Galactic plane
We present a catalogue of point-source Hα emission-line objects selected from the INT/WFC Photometric Hα Survey (IPHAS) of the northern Galactic plane. The...
The isotopic mixture of barium in the metal-poor subgiant HD 140283
Analyses of the abundances of neutron-capture elements have led to the belief that these elements in metal-poor stars are r-process products with relative...
