HIGHLIGHTS
- who: GRAVITY Collaboration and colleagues from the Trigonometry is the basis of distance measurementsThe parallax method uses the motion of the Earth around the Sun to measure the angular displacement of a nearby star (Bessel, ). From the Hipparcos satellite of the European Space Agency (ESA have published the article: A geometric distance to the supermassive black Hole of NGC, in the Journal: (JOURNAL) of 20/04/2019
- what: The authors explore the potential of BLR-based geometric distances to directly constrain the Hubble constant H0 and identify differential phase uncertainties as the current dominant limitation . . .
