In this lecture we will survey the landscape of possible contributions to the total \u2018gravitational wave background\u2019 within this frequency band. Crucially we will find that the inspiral phases of stellar-mass compact binary systems cumulatively produce a signal well within reach of the proposed AION-km and AEDGE experiments. Not only will this form a relevant background to searches for other sources of GW at these experiments, but it constitutes an interesting signal in its own right which may have much to reveal about the Universe. We will further show that hypothetical populations of dark sector exotic compact objects such as fermion and boson stars could generate signatures unique to mid- and low-frequency gravitational wave detectors, providing a novel means to probe complexity in the dark sector.About the speaker\u00a0Hannah Banks is a PhD student at the Department for Applied Mathematics and Theoretical Physics at the University of Cambridge. She was lucky enough to spend a year at CERN on the Doctoral Students Programme within the QTI-TH branch.Collaborators: Matthew McCullough, Dorota Grabowska.","endDate":"2023-06-21T12:00:00+02:00","location":{"@type":"Place","address":"No address set","name":"CERN"},"name":"Echos in the Dark: Gravitational waves from colliding ECOs at Atom Interferometers","performer":[{"@type":"Person","affiliation":{"@type":"Organization","name":"University of Cambridge"},"name":"Hannah Molly Banks"}],"startDate":"2023-06-21T11:00:00+02:00","url":"https://indico.cern.ch/event/1255934/"} </script> <script type="text/javascript" src="/assets/i18n/en_GB.js"></script> <script type="text/javascript" src="/assets/i18n/en_GB-react.js"></script> <script type="text/javascript" src="/assets/js-vars/global.js"></script> <script src="/dist/js/exports.88bb921b.bundle.js"></script> <script src="/dist/js/common-runtime.23156d3d.bundle.js"></script> <link rel="stylesheet" href="/dist/css/common.c1d85dae.css" /> <script src="/dist/js/common.53c60872.bundle.js"></script> <link rel="stylesheet" href="/dist/css/react.c0eb75b7.css" /> <script src="/dist/js/react.cbe66cee.bundle.js"></script> <script src="/dist/js/semantic-ui.32899e53.bundle.js"></script> <link rel="stylesheet" href="/dist/css/semantic-ui.03304b73.css" /> <link rel="stylesheet" href="/dist/css/jquery.dee9784c.css" /> <script src="/dist/js/jquery.a9536603.bundle.js"></script> <link rel="stylesheet" href="/dist/css/main.bae03e7a.css" /> <script src="/dist/js/main.3d6afa70.bundle.js"></script> <script src="/dist/js/module_core.5cfba714.bundle.js"></script> <script src="/dist/js/module_events.creation.f24ad529.bundle.js"></script> <script src="/dist/js/module_attachments.7bdcd885.bundle.js"></script> <script src="/dist/js/outdatedbrowser.474403ac.bundle.js"></script> <link rel="stylesheet" href="/dist/css/outdatedbrowser.17d2ff9d.css" /> <script src="/dist/js/module_events.display.59645e8e.bundle.js"></script> <script src="/dist/js/module_events.contributions.0c5df12b.bundle.js"></script> <script src="/dist/js/module_events.header.1ef6cec6.bundle.js"></script> <script src="/dist/js/module_events.search.49360505.bundle.js"></script> <script src="/dist/js/module_vc.0ba71b8f.bundle.js"></script> <script src="/dist/js/module_events.cloning.08447b32.bundle.js"></script> <script src="/dist/js/module_events.importing.f9462014.bundle.js"></script> <link rel="stylesheet" href="/dist/css/themes_lecture.6787dd7c.css" /> <link rel="stylesheet" href="/static/plugins/owncloud/dist/css/main.9fc172fa.css" /> <script src="/static/plugins/conversion/dist/js/main.df56b341.bundle.js"></script> <script src="/static/plugins/ravem/dist/js/main.f3a86d52.bundle.js"></script> <link rel="stylesheet" href="/static/plugins/conversion/dist/css/main.68b4f5cc.css" /> <link rel="stylesheet" href="/static/plugins/vc_zoom/dist/css/main.d5d0f591.css" /> <script src="/static/plugins/owncloud/dist/js/owncloud.ccba48fe.bundle.js"></script> <script src="/static/plugins/ursh/dist/js/main.583c4589.bundle.js"></script> <script src="/static/plugins/vc_zoom/dist/js/main.a1f20b82.bundle.js"></script> <script> moment.locale(["en-gb", 'en']); IndicoGlobalVars.isUserAuthenticated = false; </script> <script type="text/javascript" src="/assets/js-vars/user.js"></script> <script src="/dist/js/mathjax.285a258c.bundle.js"></script> <link rel="stylesheet" type="text/css" href="/static/custom/css/footer.css"> <!-- Piwik --> <script> (function() { 'use strict'; var url = '//piwik.web.cern.ch/'; var g = document.createElement('script'); var s = document.getElementsByTagName('script')[0]; g.type = 'text/javascript'; g.defer = true; g.async = true; g.src = url + 'piwik.js'; g.onload = init_tracking; s.parentNode.insertBefore(g, s); function init_tracking() { try { track_site(); track_event(); } catch(err) {} } function track_site() { var general_tracker = Piwik.getTracker(url + 'piwik.php', 59); general_tracker.enableLinkTracking(); general_tracker.trackPageView(); } function track_event() { var event_tracker = Piwik.getTracker(url + 'piwik.php', 56); event_tracker.enableLinkTracking(); event_tracker.setCustomVariable(1, 'Conference', '1255934', 'page'); event_tracker.trackPageView(); } })(); </script> <!-- End Piwik Code --> </head> <body data-user-id="null" data-debug="false" data-tinymce-content-css="["/dist/css/common.c1d85dae.css","/dist/css/react.c0eb75b7.css","/dist/css/semantic-ui.03304b73.css","/dist/css/jquery.dee9784c.css","/dist/css/main.bae03e7a.css"]" > <ind-bypass-block-links></ind-bypass-block-links> <div class="header"> <div class="announcement-bar weak-hidden warning" data-hash="2449555847"> <div class="flexrow f-self-stretch f-j-center f-a-center"> <i class="icon icon-warning"></i> <div> <p>Help us make Indico better by taking <a href="https://forms.gle/a8cYVhuBxMfFjSb98">this survey</a>!

In this lecture we will survey the landscape of possible contributions to the total ‘gravitational wave background’ within this frequency band. Crucially we will find that the inspiral phases of stellar-mass compact binary systems cumulatively produce a signal well within reach of the proposed AION-km and AEDGE experiments. Not only will this form a relevant background to searches for other sources of GW at these experiments, but it constitutes an interesting signal in its own right which may have much to reveal about the Universe. We will further show that hypothetical populations of dark sector exotic compact objects such as fermion and boson stars could generate signatures unique to mid- and low-frequency gravitational wave detectors, providing a novel means to probe complexity in the dark sector.</p><p><strong>About the speaker</strong> <br><span style="color:hsl(210,75%,60%);"><strong>Hannah Banks</strong></span> is a PhD student at the Department for Applied Mathematics and Theoretical Physics at the University of Cambridge.
