The goal of my research is to detect a continuous gravitational wave
signal (CW). I coordinate the deployment of the Einstein@Home CW
searches on LIGO and Virgo data and the mining of the results. These
searches have consistently been the deepest searches on any data set
and, in the absence of a detection, they have provided the tightest
constraints on the amplitude of CW signals at Earth [1, 2, 3, 4, 5, 6].
in hand with this work on the data goes the improvement of the search
methods, the development of optimisation techniques to pick the most
promising signals to search for and investigations to explore different
emission mechanisms [7, 8, 9].
CW searches are computationally
limited. For this reason we use the Einstein@Home volunteer computing
project, with its Petaflop performance, as our main work-horse. There is
a non-trivial overhead associated to setting-up each Einstein@Home
search, which must run flawlessly on hundreds of thousands of different
computer architectures and operating systems.
Access to advanced
LIGO/Virgo data is an amazing opportunity to make the first detection
of a continuous gravitational wave signal. Directly through my own work
and by coordinating the work of a broader group of people, this is what I
strive to achieve.
