Dust Build-Up at High-z
Posted in Projects
ALMA has observed extremely dusty, star-forming galaxies (DSFGs) at \(z>5\) in the rest-frame infrared and JWST has found a population of extremely reddend galaxies in the optical (i.e. highly dust attenuated) previously undetected by Hubble. These DSFGs at such high redshifts are a surprising find, opening up many questions:
- How can galaxies form so much dust when the Universe is \(\lesssim 1\) Gyr old?
- Can these observations constrain uncertainties in the dust life cycle?
- Are observations of DSFGs biased to an extreme subsample of galaxies?
Using simulations of galaxies at high redshift incorporating dust evolution models, I attempt to answer these questions and provide insights for future observations with JWST.
