surrounding gaseous halos, the so-called circumgalactic medium (CGM), </div><div class="">extending over tens of kpc. A solid characterisation of both galactic
gas flows and chemical composition of the CGM is thus crucial to </div><div class="">understand galaxy evolution, especially in the first few Gyrs of cosmic
time, when galaxies rapidly assembled their masses and reached their
chemical maturity.<br class="">
I will present new studies on galactic outflows and CGM metal enrichment
in the early Universe, exploiting recent data from the ALMA large
program ALPINE, </div><div class="">that observed [CII] and dust in more than hundred
star-forming galaxies at z~4-6.</div><div class=""><br class=""></div>Link: <a href="https://uniroma1.zoom.us/j/85962662885?pwd=UDFLcTYrWHNSWm5uQ1ZrbEhsalVUUT09" target="_blank" class="">https://uniroma1.zoom.us/j/85962662885?pwd=UDFLcTYrWHNSWm5uQ1ZrbEhsalVUUT09</a><br class=""><div class="">
