Hi all,

our final astronomy seminar of the term will be given by Francesco D'Eugenio, talking about feedback and quenching at high redshift.  We have booked C5, but if C4 is free we will move there as the lights are better (C4 is booked at the seminar time but may well be empty).

Post-seminar refreshments will be wine and cheese.

Timings are as usual:

- lunch at Lakeside, leaving CAPT ~13:00 (subsidised for a limited number of students -- let me know before the end of the day tomorrow)
- meet the speaker for postgrads at 15:00, finishing at 15:30
- seminar at 15:45 in C5/C4
- post-seminar wine and cheese at 16:45

This seminar will be conducted in person only.

Best,
Jesse and Luke

Feedback and quenching at high redshift through JADES and GA-NIFS

How galaxies stop forming new stars (quenching) is one of the major open problems in astrophysics.
Large spectroscopy survey at z~0-1 have enabled tremendous progress in this field, highlighting the role of AGN in queching massive galaxies.
But the advent of JWST is providing new and stringent constraints on the physical processes responsible for quenching, challenging our picture of galaxy formation and quenching.
I will start by presenting new results from JWST NIRSpec integral-field spectroscopy of massive, post-starburst galaxies at z~3-5, revealing stellar rotation, a gas-rich CGM, and ongoing AGN feedback. I will then move to lower-mass systems at higher redshifts (possible progenitors) showing evidence of ongoing AGN feedback. I will then discuss internal feedback mechanisms and the open questions about the transition between stochastic star-formation histories and long-term quenching.
