CosmoGen employs evolutionary algorithms for symbolic regression to generate dark energy fluid models that alleviate S8 and H0 tensions, with Bayesian analysis of one model showing tension relief though weaker preference than LambdaCDM.
Simulations reveal that two-parameter extinction PDFs fit SN Ia data better than the exponential, implying intrinsically redder supernovae by about 2 sigma.
A tenfold larger sample of AGN radio source sizes confirms a real angular size-redshift relation but indicates that scatter must drop below 20% or samples reach thousands to 100,000 to constrain Ω_m effectively.
A new two-parameter empirical magnitude-redshift relation for Type Ia supernovae fits observations comparably or better than LambdaCDM and indicates uniform cosmic acceleration.
This white paper recommends that the Astro2020 decadal survey explicitly advocate for and increase funding of modest-aperture public telescopes to sustain a competitive and efficient US optical/infrared observing system.

Revisiting the angular size-redshift cosmological test with milliarcsecond radio structures in active galactic nuclei
A tenfold larger sample of AGN radio source sizes confirms a real angular size-redshift relation but indicates that scatter must drop below 20% or samples reach thousands to 100,000 to constrain Ω_m effectively.
