Aims: We introduce the Chromospheric Telescope (ChroTel) at the Observatorio del Teide in Izaña on Tenerife as a new multi-wavelength imaging telescope for full...
The CIDA-UCM-Yale shallow survey for emission-line galaxies
We present the CIDA-UCM-Yale (Centro de Investigaciones de Astronomía, Universidad Complutense de Madrid, and Yale University) Survey (CUYS) for Hα+[NII] 6549...
The Circular Polarization of the Mn 1 Resonance Lines around 280 nm for Exploring Chromospheric Magnetism
We study the circular polarization of the Mn I resonance lines at 279.56, 279.91, and 280.19 nm (hereafter, UV multiplet) by means of radiative transfer...
In this paper, we study the circumgalactic environment of LINER host galaxies, in a sample of 166 objects drawn from a Multifrequency Catalogue of LINERs by...
The circum-galactic medium of quasars: transverse and line-of-sight absorptions
Quasar projected pairs (QPPs) can be used for investigating the circumgalactic medium of quasars through the study of intervening absorption lines in the...
The circumburst density profile around GRB progenitors: a statistical study
According to our present understanding, long gamma-ray bursts (GRBs) originate from the collapse of massive stars, while short bursts are caused by to the...
The circumnuclear environment of NGC 613: a nuclear starburst caught in the act?
We present near-infrared (H- and K-band) integral-field observations of the inner ˜700 pc of the active spiral galaxy NGC 613, obtained with SINFONI on the Very...
The circumnuclear region in the Seyfert 1 galaxy NGC 3227
This article presents Hα and [O iii] narrow-band images and long-slit optical and near-infrared spectroscopy at position angles 65.5 deg and 25 deg through the...
The circumnuclear region in the Seyfert 2 galaxy NGC 5953
This article presents narrow-band Hα and [OIII] images of the interacting pair of galaxies NGC 5953 (with a Seyfert type 2 nucleus) and NGC 5954 (with a LINER)...
