Star Formation — the Tai Chi between Gravity, Turbulence and Magnetic Fields (Webinar, Friday 11th September @ 11:30)

Li Hua-bai (Chinese University of Hong Kong) Since 1980’s, astronomers realized that gravity, turbulence and magnetic fields may all take part in the process of star formation. But how exactly these three forces interact with each other and result in the observed, e.g., star formation rate, efficiency, and stellar mass distribution remains as one of …

Importance of WN stars on the ionisation and chemical evolution of galaxies (Webinar, Friday 22nd May @ 11:30)

Arpita Roy (Australian National University) Massive stars are primary sources of chemical yields and mechanical and ionization luminosity budgets. Therefore, understanding massive stars’ evolution is crucial to have a complete understanding of the chemical and ionization evolution of galaxies. Moreover, with the advent of instruments like MUSE, JWST (upcoming), HST, etc., we have (/are going …

Receiving Credit for Research Software (Webinar, Friday 15th of May @11:30)

Alice Allen (Editor of the Astrophysics Source Code Library – ASCL ascl.net) Journal articles detail the general logic behind new results and ideas, but often the source codes that enable these results remain hidden from public view and those who author these computational methods have not always received credit for their work. This presentation will …

On the origin of Lithium

Paolo Molaro (Astronomical Observatory of Trieste) Abstract: Li is the element with the largest number of astrophysical nucleosynthetic processes. Although a primordial element, it is also produced by spallation processes in the interstellar medium, in a slow process lasting billions of years. The Li abundance in the old halo population of the Galaxy, however, is …

Tensions in cosmological data: impact of non standard models and systematic effects

Matteo Martinelli (Instituto de Fisica Teorica UAM/CSIC) Abstract: In recent years, measurements of cosmological parameters coming from different observables have shown tensions between each other, the most striking the approximately 4.5 sigma tension on the Hubble constant between CMB and local measurements. In this talk I will briefly review the status of these tensions and …
