Topic: New constraints on the Post-Newtonian parameter and cosmic curvature are derived from galaxy-scale strong lensing, SNe Ia, BAO, and cosmic chronometers, testing general relativity on kiloparsec scales.
Topic: A new observational test of thermogravity theory is presented, exploring cosmic acceleration without vacuum energy by modifying Einstein's equations.
Topic: The Hubble constant ($H_0$) is inferred using the Tip of the Red Giant Branch method, calibrated with geometric anchors from the Large Magellanic Cloud and NGC 4258.
