Hello dear cruncher!

E@H was primarily founded to confirm the existence of gravity waves. This happend and lead me to my following questions:

- Why do nobody mention the important  contribution of all private crunchers?

- Why are there no news on boinc and on the website of E@H? It seams to me, that we are indifferent to the maintainer of the site.

- What's the new aim of E@H?

I believe from the beginning

I believe from the beginning the intent was to contribute to gravity wave astronomy, an interest which did not terminate with the first detection.  There has been lots of material posted here regarding gravity wave event detections to date (four, I think), but it is important to note that none of those detections have been the product of work performed here.

Long since, this effort has added some other forms of astronomical detection to our gravity wave interest.  In particular, the searches for gamma-ray pulsars in radio astronomy data done here have resulted in dozens of new detections, with multiple scientific papers.  All of this has been quite substantially publicized and discussed on this site.

The gravitational waves E@H

The gravitational waves E@H is searching for are not the coalescence of black holes, which is the only detection so far.  E@H is looking for GW from rapidly rotating neutron stars.  Different frequency band and much lower amplitude signal.

Thanks Gary for this

Thanks Gary for this answer!

But why it's so important to also find GW from rapidly rotating neutron stars? :)

Because those emissions are

Because those emissions are continuous.  The universe is awash with them but they're currently 'invisible'.

For gravitational wave astronomy to be really useful we need to be able to 'see' continuous emissions.

 

Cheers,
Gary.

The other reason is "why not?" GW may have lots of sources and currently the only ones that have been observed, and made the news, have been from mergers of compact binary objects, such as black holes. But there may be other sources and other interesting scientific discoveries to be found, and sometimes the approach is to look for a theorietical/predicted signal. Hence the continuous wave search and E@H's GW search.

(Also, moved discussion to Science fourm.)
