A sub-ppm upper limit on the cosmological variations of the fine structure constant alpha
S. Muller, A. Beelen, M. Guelin +9
Absorption spectroscopy toward high-redshift quasars provides strong constraints on the putative variation of fundamental constants of physics on cosmological time scales. The subm…
High resolution mapping of molecular tori with ALMA
F. Combes, A. Audibert, S. Garcia-Burillo +11
Recent high resolution mapping of the circum-nuclear regions of Active Galactic Nuclei (AGN) has revealed the existence of geometrically thin nuclear disks, in general randomly ori…
Millimeter emission from supermassive black hole coronae
S. del Palacio, C. Yang, S. Aalto +28
Active Galactic Nuclei (AGN) host accreting supermassive black holes (SMBHs). The accretion can lead to the formation of a hot, X-ray emitting corona close to the SMBH capable of a…
High resolution ALMA observations of HS in LIRGS (Dense gas and shocks in outflows and CNDs)
M. T. Sato, S. Aalto, S. König +14
Molecular gas plays a critical role in regulating star formation and nuclear activity in galaxies. Sulphur bearing molecules, such as H2S, are sensitive to the physical and chemica…
