New E@H results paper available on arXiv

A new paper describing the results of the O1MD1 Einstein@Home search is now available on the arXiv preprint server at https://arxiv.org/abs/1903.09119 . While no astrophysical signals were found, "Results from an Einstein@Home search for continuous gravitational waves from Cassiopeia A, Vela Jr. and G347.3" describes the search and sets upper limits on the amplitude of continuous gravitational waves from the three supernova remnants at an unprecedented level. of sensitivity. The paper will now be submitted to a journal for peer review and publication.      

The three targets were chosen based on the estimated age of and distance to supernova remnants, based on an optimisation procedure that we developed in the past years. While we can see those objects in X-rays, no associated pulsations in radio waves or any other part of the electromagnetic spectrum have been detected so far. This means that the spin frequency of these objects is unknown, and hence we have to search over a very broad range of frequencies and possible frequency evolutions. It is only with the help of the massive computing power provided by the volunteers of Einstein@Home that we were able to achieve these results.   

As our methods, computing power and the sensitivity of the detectors improve, we continue the hunt for continuous gravitational waves and we invite the E@H volunteers to continue to support us in this exciting science quest.

May seem that, The radio wave

May seem that, The radio wave spectrum of the data set  Cas A, Vela Jr. and G347.3 searches can be examined for other properties of the radio search; Such as the emission spectrum of the stars & also the type of signals received..

Such as the modulation of the waves where such data as we all need about stars will be found.. If only to find data that avoids error in SETI or spectral analysis for contained matter.

For Example the wave bands of the 3 neutron stars are 90% match for one another at the level of the pictogram!

However there are a few differences between the stats of the stars.. Maybe accounting for mas/age content & energy values, We can compare the 3 in a matrix to find the variable examination compared to known size, Spin rate & other factors for further research on size and age variable data.

FRB found at less than 50000000 LY https://www.newsweek.com/radio-signal-milky-way-frb-1501479

https://is.gd/EinsteinGPU would suggest a power consumption range in the following ranges:

(Variable on component use)(+V)
Watching movies: variable 5watt to 30Watt+V
Lighter load GPU play (Lighter load) 25Watt to 110Watt variable +V
Medium GPU play 60Watt to 130Watt+V
Heavy GPU play 80Watt to 220WATT+V maximum power on CPU + GPU
