I've recently stumbled across this new article. A german news site summarizes it as follows:

The authors have developed a new analytic model of the gravitational wave signals, which are to be expected from collisions of neutron stars. This reduces the computational requirements of this task from many months on the best supercomputers to a few seconds on a workstation.

There is no mention of Einstein@Home and I see no connection in the authors' list, so you may not be aware of this. I could imagine this work to be useful for Einstein@Home to better predict what you/we are looking for.

new analytic model for signal from colliding neutron stars

Here's the main claim ( my emphasis ) :

Quote:
Our model is the first semi-analytical model which captures the tidal amplification effects close to merger. It thereby provides the most accurate analytical representation of binary neutron star dynamics and waveforms currently available.


which would emerge as signal templates for inspiral/merges cases. However we analyse continuous waves here ie. that for which the time evolution is very little or none.

Don't worry, I was here for four years before it was kindly pointed out to me that we don't do inspirals ! :-)

Cheers, Mike.
