[Astronomy seminar announcements]

Dear all,

The next SU astronomy departmental seminar will take place on Friday May 5th at 10:30 in room FC61 (AlbaNova building, 6th floor) and on zoom (https://stockholmuniversity.zoom.us/s/61002076352 <https://stockholmuniversity.zoom.us/s/61002076352>).

Title: The formation of star clusters in low-metallicity environments
https://www.albanova.se/event/astronomy-departmental-seminar-natalia-lahen-mpia/ <https://www.albanova.se/event/astronomy-departmental-seminar-kelley-hess-csic/>

Abstract:
Despite the efforts of observational surveys to map the formation sites 
of globular clusters (GCs) at redshifts beyond z~2, the spatial 
resolution even in the deepest lensing surveys will still be limited to 
scales of parsecs. Numerical experiments with star forming environments 
typical to high-redshift Universe are therefore needed to probe the 
formation of GCs down to the details of their internal structure. In the 
GRIFFIN project, we model the formation of stars, star clusters and GCs 
in low-metallicity gas-rich dwarf galaxies. We use the SPHGal code, 
modified from GADGET-3, that includes a chemical network to model the 
low-temperature cooling of the multiphase ISM. Star formation and 
feedback prescriptions include a fully realized IMF and feedback from 
single stars. Using isolated and merging dwarf galaxy models, we are 
able to follow the formation and evolution of star clusters within their 
full galactic environments. I will discuss how massive star clusters up 
to the mass range of GCs form in the most extreme star-forming 
environments probed by our simulations. In our new simulations, we 
implement the element-by-element enrichment of the ISM by stellar winds 
and supernovae of massive stars, and investigate the build-up of 
chemical variations within the stellar populations of massive star 
clusters.

We look forward to seeing many of you there. Thanks!
