On Friday the 25th at 10:30 we have our next seminar with Carlos
Gomez Guijarro (CEA) speaking via Zoom.<br>
<p><b><span>Understanding the role of compact star formation in
galaxy evolution</span></b></p>
<p><span>Massive elliptical galaxies in the local universe appear to
have their high-redshift analogues in the form of extremely
compact quiescent galaxies. Therefore, it seems that compact
star formation appears to play a pivotal role in the
evolutionary pathways of massive galaxies across cosmic history.
However, there are fundamental unresolved questions debated in
the literature: How systematic is compact star formation in
star-forming galaxies at high redshift? What is its role in the
broader picture of the scaling relations in galaxy evolution? I
will present the latest results of the GOODS-ALMA survey, a
1.1mm ALMA survey aimed to tackle these questions. Compact star
formation appears to be the norm in massive star-forming
galaxies at high redshift and sizes as extended as typical
star-forming stellar disks are rare. It unveils as a physical
driver of the behaviour of massive star-forming galaxies in the
scaling relations. The new findings suggest that compact star
formation is fundamental in keeping galaxies as star forming
systems even when their gas to fuel star formation is very low
and they are presumably on their way to quiescence.</span></p>
<p>We are trying something new this year with leaving the Zoom call
open after the formal hour of the seminar is up to allow the
speaker, if they wish, to chat informally with anyone who is
interested.</p>
