In 1970 while at Mondadori Publishing House I published and article by prof. Peter G.Bergmann on recent researches in General Relativity. His article ended with the prediction  that researches in General Relativuty would join researches in elementary particle physics to become the bleeding edge of physics. He was right.

Excellent work.  Thank you.

Great video!

Which subproject of Einstein@home searches for those gravitational waves caused by the "hill" on the neutron star? Is it just the "O3 All Sky"-subproject or are there other ones?

No, those pulsars were just added at scientifically plausible position that hat nothing to do with the Einstein@Home discoveries.

In fact, it can be quite hard to exactly determine the distance to pulsars, so the exact position is usually not known. For radio pulsars, the distance is usually determined from the amount of dispersion (high-frequency radio waves arrive earlier than low-freqency waves) in the received radio pulses. This dispersion tells us the summed free electron density along the line of sight. Models of this electron density in our Galaxy then allow us to estimate the distance. But since these models have uncertainties the distances can also be off by tens of percent.
