A new preprint from the DESI-eRASS1 survey (arXiv:2605.28921, not yet peer-reviewed) maps how X-ray AGN activity and star formation interact across the main sequence while explicitly separating disk- and spheroid-dominated hosts via Sersic index. With 1171 X-ray AGN and 45,374 control star-forming galaxies at z ≤ 1.5, the authors find that SFR_norm stays near unity at moderate luminosities but rises sharply at high L_X, with the transition luminosity shifting higher in more massive galaxies. Critically, this enhancement appears only in disk-dominated systems; spheroids remain flat. The incidence of AGN rises steeply with distance above the main sequence, more so at higher redshift, and the slope itself depends on morphology. This work improves on earlier studies (Aird et al. 2019, MNRAS; Yang et al. 2023, ApJ) that reported average trends without morphology splits, missing the structural modulation. The morphology dependence aligns with simulations showing that disk instabilities efficiently funnel gas to both star formation and central black holes, while spheroids rely on external triggers that are rarer on the main sequence. Limitations include reliance on X-ray selection (missing heavily obscured AGN) and photometric morphology at higher z. The result strengthens the view that global gas supply sets the stage, but internal structure decides whether black-hole growth couples tightly to star formation or proceeds quietly.
