Matched filtering techniques have shown to be very effective for searching for gravitational signals in the LIGO and Virgo data (dominated by instrumental noise). Matched filtering consists in correlating the data with a set of waveform templates (called bank) that provides a discrete sampling covering the entire relevant astrophysical parameter space. Template banks capable for covering the accessible parameter space typically include 500,000 waveforms. Correlating with this many templates thus represents a large computing cost. The goal of this work is to investigate ways to reduce the gravitational-wave template banks through random projections and to perform this reduction efficiently using Optical Processing Units.<\/p>\n \u00a0<\/p>\n \u00a0<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row custom_margin=”120px||” _builder_version=”3.22.1″ admin_label=”Row” locked=”off”][et_pb_column type=”4_4″ _builder_version=”3.22.1″][et_pb_divider _builder_version=”3.22.1″][\/et_pb_divider][et_pb_text admin_label=”\u00c0 lire aussi” _builder_version=”3.22.1″ z_index_tablet=”500″ locked=”off”]<\/p>\n [\/et_pb_text][et_pb_blog posts_number=”4″ include_categories=”37″ show_author=”off” show_date=”off” show_pagination=”off” module_id=”page_type_blog” _builder_version=”3.22.1″ header_level=”h4″ border_width_bottom_fullwidth=”1px” border_color_bottom_fullwidth=”rgba(51,51,51,0.18)” custom_padding=”||50px|” z_index_tablet=”500″ locked=”off”][\/et_pb_blog][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":" 2022Masters Projects@Physics & Astronomy +Computer Science\u00a0#gravitational-wave astronomy#data reduction#random projections#optical processing units\u00a0 Project SummaryThe direct observation of gravitational waves by the LIGO and Virgo detectors is one of the breakthrough discoveries of the beginning of the 21st century.
