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.

MaNGA-based comparison shows AGN-PSBs likely evolve from RPSBs with lower merger fractions than high-mass CPSBs, indicating AGN feedback is not necessary for post-starburst formation.
Image stacking of 57 E+A galaxies shows excess extended light relative to comparison samples, consistent with faint tidal features from small-scale interactions.
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.

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.
