Halfway to the Peak


This talk presents brand new data from our JWST program "Halfway to the Peak" which investigates the relationship between star forming galaxies and their central black holes at z~0.6, halfway back to the peak epoch of galaxy evolution. This program leverages the rich diagnostic power of mid-IR spectroscopy to separate the AGN and star formation energetics in galaxies, and only now with MIRI/MRS are we able to detect the rich mid-IR atomic lines to quantify the black hole accretion rates ([NeV], [NeVI]) and spatially resolve the star formation (Br-alpha) outside the local Universe. In order to fully realize the potential of these JWST data we developed several novel reduction methods which overcome unforeseen issues with this new instrument. This talk will provide a first look at these data and our future plans for full scientific exploration. Zoom: https://umass-amherst.zoom.us/j/91015254428?pwd=dUlwZ1RadXVMcW1Jd3BiQW1KRFhIdz09
