Topic 188696

Having read through another post entitled 'Article about Einstein@Home?', I note with some sadness that hoarfrost's original request has been lost amidst a plethora of tripe.

On his behalf, therefore, I would like to request any developers of E@H, or scientists involved in the project, to write an article offering an in-depth insight into the E@H project. Formulas, algorithms, and complex science, I guess, would be appreciated.

I would suggest contacting hoarfrost with any articles, as I'm not sure whether he is involved with arxiv.org in any way.

Thanks in advance.

Re-Request: On behalf of hoarfrost

In search http://arxiv.org/find/grp_physics/1/abs:+AND+search+AND+gravitational+waves/0/1/0/all/0/1?per_page=100

on page "Next 71 results"
http://arxiv.org/find/grp_physics/1/abs:+AND+search+AND+gravitational+waves/0/1/0/all/0/1?skip=100&query_id=323f6cda3fbf6373

I have found some articles on global theme "Data analysis of gravitational-wave signals from spinning neutron stars":

http://arxiv.org/abs/gr-qc/9809046 - II. Accuracy of estimation of parameters

And:

http://arxiv.org/abs/gr-qc/9905026 - The Detection of Gravitational Waves with LIGO
http://arxiv.org/abs/gr-qc/0102019 - A nonlinear detection algorithm for periodic signals in gravitational wave detectors
http://arxiv.org/abs/gr-qc/0501007 - The Search for Gravitational Waves

and other...

I don't know about relations between seven listed articles and Einstein@Home, but these articles have drawn my attention.

Thanks a lot!

In the beginning of March we formed a little team, and questions about work and scientific principles of Einstein@Home is very interesting for us. :)

Hi folks, I've seen

Hi folks,

I've seen several requests for more details scattered around this forum. These papers

mentioned by hoarfrost are good places to find the math if you're itching to know just how the fast Fourier transforms are used.

The first paper in particular defines the "F-statistic" in equation (56), which summarizes several equations leading up to it. It's not a light read. It's basically all about how matched filtering works for a sinusoidal signal, allowing for the changing way it interacts with the moving detector over time. The "F-statistic" is the matched filtering signal-to-noise ratio with some degrees of freedom projected out.

You'll see references to it here and there, for instance when a log file says "detected finished Fstat file" or something like that.

Hope this helps,
Ben
