| Abstract: |
A direct detection of gravitational waves is
one of the most exciting frontiers for modern
astronomy and astrophysics.
Gravitational wave signals combined with classical
electro-magnetic observations, known as multi-messenger astronomy,
promise newer and deeper insights about
the cosmic evolution of astrophysical objects
such as neutron starts and black holes.
To this end, we have been developing an original
data processing pipeline for KAGRA,
a Japanese gravitational wave telescope,
for optimal detections of supernova events.
As a part of our project, we released a web
application named SuperNova Event Gravitational-wave-display
in Fukuoka (SNEGRAF) in autumn 2018.
SNEGRAF accepts the users' theoretical waveforms
more than ∼ 105 data points directly
with JavaScript, although the number can be
typical for a supernova hunt by assuming a typical
duration of the event and sampling rate of the detectors;
a combination of recursive decimations of
the original in the server-side program and
an appropriate selection of them depending
on the time duration requested by the user
in a web browser achieves an acceptable latency.
In this paper, we present the current design,
implementation and optimization algorithms of SNEGRAF,
and its future perspectives. |
