From Scaling Relations to Physical Laws: Constraining the Physics of Star Formation Across Local Galaxies

Jakob den Brok, Cecilia Bacchini, Leindert A. Boogaard +21

The conversion of cold dense gas, traced by molecular line emission, into stars remains one of the fundamental unsolved problems in galaxy evolution. Observations over the past dec…

Tracking the flow of interstellar gas across scales: from galaxies to star clusters

Ana Duarte-Cabral, Maxime Valeille-Manet, Mathilde Bouvier +30

While the baryon cycle of the interstellar medium - and its ability to form stars - plays a key role in galaxy evolution, unravelling the physical processes driving its evolution r…

The molecular diversity of the ISM in galaxies across cosmic time

Mathilde Bouvier, Yiqing Song, Michael Romano +7

Submillimetre molecular lines (e.g., CO, HCN, SiO) provide a uniquely powerful view of the physical and chemical processes that govern star formation (SF) and galaxy evolution. Yet…

A vision for ground-based astronomy beyond the 2030s: How to build ESO's next big telescope sustainably

Laurane Fréour, Mathilde Bouvier, Tony Mroczkowski +8

Astronomy is the study of the Universe and all the objects that it comprises. Our attention is therefore usually focused beyond Earth, home to the only form of life known today. Ho…
