We present the results of a recently conducted mm-experiment at the IRAM 30m telescope. We searched in two QSO hosts for the HCN(J=1-0) line emission tracing the dense regions of gas. Our goal is to probe the HCN-CO line ratio in QSO hosts for the first time and to compare the results with recent findings of quiescent galaxies. These findings indicate a strong correlation between the star formation efficiency and the HCN-CO line ratio over several orders of magnitudes in infrared luminosities.
We present ALMA observations of the CO(6-5) and [CII] emission lines and the sub-millimeter continuum of the $zsim6$ quasi-stellar object (QSO) SDSS J231038.88+185519.7. Compared to previous studies, we have analyzed a synthetic beam that is ten time
We present observations with the IRAM Plateau de Bure Interferometer of three QSOs at z>5 aimed at detecting molecular gas in their host galaxies as traced by CO transitions. CO (5-4) is detected in SDSSJ033829.31+002156.3 at z=5.0267, placing it amo
Recent surveys of the Galactic plane in the dust continuum and CO emission lines reveal that large ($gtrsim 50$~pc) and massive ($gtrsim 10^5$~$M_odot$) filaments, know as giant molecular filaments (GMFs), may be linked to galactic dynamics and trace
We present the 3 mm wavelength spectra of 28 local galaxy merger remnants obtained with the Large Millimeter Telescope. Fifteen molecular lines from 13 different molecular species and isotopologues were identified, and 21 out of 28 sources were detec
High-Velocity Clouds (HVCs) have radial velocities that cannot be explained by the global Galactic rotation; their distances remain mostly unknown, and their true nature and origin are still a mystery. Some of them could be of galactic origin, or bel
