The local gravitational tides are really good at connecting the properties of dark matter halos to the cosmic web.
Can we a-void the Hubble tension with local voids?
Cosmologists revisit an idea for addressing the Hubble tension: that a local void is messing with our measurements along the cosmic distance ladder.
