Constraints on the gravitational potential from DESI DR2 BAO and its implications for the local void scenario

Indranil Banik, José Antonio Nájera, José Antonio Nájera +1

The authors use DESI DR2 BAO together with CMB, BBN and cosmic‑chronometer data to measure any gravitational potential offset between the Milky Way and distant sources, testing whe…
