SUMMARY:Mid-Infrared diversity in nearby AGN: New insights from JWST/MIRI

DESCRIPTION:Type-2 quasars (QSO2s) are luminous active galactic nuclei cha
 racterized by narrow optical emission lines. They are the torus-obscured c
 ounterparts of type-1 quasars\, although in some cases\, part of the obscu
 ration arises from galactic scales. Thanks to JWST\, it is now possible to
  study the properties of nuclear gas and dust in local AGN with unpreceden
 ted spatial and spectral resolution and sensitivity. In this talk\, I will
  present recent results from Cycle 2 JWST/MIRI observations of nearby QSO2
 s from the QSOFEED sample\, which revealed a striking diversity of mid-inf
 rared spectral shapes and features\, and compare them with JWST/MIRI data 
 of Seyfert galaxies from the Galactic Activity\, Torus\, and Outflow Surve
 y (GATOS). Our findings highlight the complexity of these nuclear environm
 ents and underscore the need for larger JWST samples to disentangle the ro
 les of obscuration\, ionizing continuum\, gas density\, and other factors 
 in shaping their mid-infrared spectra.\n
