We present preliminary results from a survey of cold gas in an intermediate-redshift cluster, Zw Cl0024.1+1652 at z = 0.395, using the EMIR receiver at the IRAM...

One of the most challenging open questions in Astrophysics is how Active Galactic Nuclei (AGNs) are fueled. For this to happen, gas has to be driven from the...

Near-infrared spectroscopy was conducted to search for molecular material around 40 post-AGB stars. We present the detection of molecular emission lines of H2...

We present high spatial resolution ($\approx60$--90 milliarcseconds) images of the molecular hydrogen emission in the Planetary Nebula (PN) NGC~2346.The data...
