Our paper The Atacama Cosmology Telescope: Multi-probe cosmology with unWISE galaxies and ACT DR6 CMB lensing is now on the arXiv (2409.02109) and submitted to Phys. Rev. D. It builds directly on our 2023 ApJ paper, jointly fitting galaxy auto-correlation, galaxy–lensing cross-correlation, and the CMB lensing auto-spectrum to deliver tighter constraints on structure growth.
