[Astronomy seminar] Astronomy Department Seminar - February 25th Carlos Gomez Guijarro

[Astronomy seminar announcements]

On Friday the 25th at 10:30 we have our next seminar with Carlos Gomez 
Guijarro (CEA) speaking via Zoom.

*Understanding the role of compact star formation in galaxy evolution*

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.

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.

Thanks
Chris and Carolina
