DESCRIPTION:Speakers: Krzysztof Lisiecki (NCBJ BP4)\nUnderstanding how sta
 r formation history (SFH) models influence galaxy evolution is still a maj
 or challenge\, especially for quiescent galaxies (QGs). SFH dictates not o
 nly stellar mass assembly\, but also governs quenching pathways and timesc
 ales. JWST's unprecedented sensitivity enables us to resolve discrepancies
  in SFH modelling\, particularly for recently discovered dust-rich QGs at 
 high redshifts (z ~ 3)\, where near- and mid-infrared (NIR and MIR) emissi
 on plays a crucial role.\nI present a comprehensive analysis of the impact
  of various SFH models\, including non-parametric approaches\, on the QGs\
 , including dust-attenuated ones. Using a sample from the CEERS survey det
 ected with NIRCam and MIRI up to z ~ 6\, I have reconstructed SFHs by inte
 grating UV-MIR photometry. This enabled me to constrain quenching timescal
 es and evaluate the influence of MIRI detections on QG selection and dust 
 properties. I quantified the effects of SFH on the physical properties and
  selection of QGs.  I will discuss the reliability of SFH recreated with 
 photometry alone in recovering quenching-related timescales.\n\nhttps://ev
