The Sparks survey divides local galaxies into first-burst, second-burst, and post-burst groups, finding AGN predominantly in second-burst systems and implying a short delay before black hole accretion.

Morphological metrics in galaxy images suffer systematic biases from resolution, depth, and noise that can be quantified and corrected empirically, with new metrics proposed to reduce those effects.
Post-starburst galaxies at cosmic noon show very low radio detection rates and compact weak sources, consistent with short-lived low-luminosity AGN, while older quiescent galaxies exhibit stronger extended radio emission.
Panchromatic SED modeling yields SFRs with smaller offset and scatter than optical-only fits for starburst to post-starburst galaxies, while Prospector AGN torus models distinguish AGN but underpredict luminosities by an order of magnitude.

Tracing Radio AGN-Driven Quenching in Post-Starburst Galaxies at Cosmic Noon
Post-starburst galaxies at cosmic noon show very low radio detection rates and compact weak sources, consistent with short-lived low-luminosity AGN, while older quiescent galaxies exhibit stronger extended radio emission.

Sparks II: Panchromatic SED modeling and galaxy physical properties across the starburst to post-starburst sequence
Panchromatic SED modeling yields SFRs with smaller offset and scatter than optical-only fits for starburst to post-starburst galaxies, while Prospector AGN torus models distinguish AGN but underpredict luminosities by an order of magnitude.
