Thanks Martin, but I already knew most of the materials in the course, except inflation. I had written about gravitational waves in 1970 on a Mondadori Yearbook and was scolded by prof. Antonino Zichichi, an Italian elementary particle physicist. Then we had only the results of Joseph Weber with his resonant mass detectors, and they were not accepted. But his basic idea of having detectors in different localities and consider an event only if it was recorded at different locations within a short interval of time was used also at LIGO. Now let us see what Virgo can do.

LISA has been approved by ESA for launch in 2034. I have read about it in the NASA site.

Good news for LISA. Too bad

Good news for LISA. Too bad it's scheduled in 2034 so probably sometime after that.

Hallo!
Tonight will start the GRACE Follow-On Mission, which has a 30GHz interferometer for distance measurement on board not only, but also an optical interferometer. This is an advanced test for the lasers to be used for eLISA, but over distances of about 200Km. Hopefully this will increase the accuracy of distance measurement by a factor of 20.
We cross all of our fingers for success!!!
Kind regards and happy crunching

Hallo!
|| This is an advanced test for the lasers to be used for eLISA ||
It has been successfully started, see : here and here and in german.
Does it uses quenched laserlight? I don´t believe so. It would consume too much power and too big in size for such a small satellite.
Nevertheless it´s a great step forward. Congratulations to the people of AEI!!!!
We do wait now for detailed tests, to see the advantage over the microwave interferometer.
It´s a good day for eLISA.
Kind regards and happy crunching
