for the next-generation gravitational-wave detectors in the US, Cosmic Explorer. Advanced LIGO so far has observed over one hundred gravitational-wave transients from binary black hole and neutron star collisions. For the first time we can optimize the design of the next-generation detectors with good guidance on observable signals. Intriguingly, Cosmic Explorer will be able to observe binary black hole mergers throughout comic times, all the way back to mergers of remnants of the first stars. It will also observe neutron star mergers with high fidelity, putting constraints on this nuclear state of matter, and it will provide high-signal-to-noise measurements of black hole dynamics.<\/p><p>This talk will focus on the detector technology required for Cosmic Explorer. It will touch on its sensitivity limitations, the prospects for further sensitivity improvements, and will discuss project timeline and challenges. I will highlight the technologies and expertise needed to build and operate those detectors.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-d1d00bf\" data-id=\"d1d00bf\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-27c5441 elementor-widget__width-initial elementor-widget elementor-widget-image\" data-id=\"27c5441\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"1920\" height=\"1080\" src=\"https:\/\/www.physics.nus.edu.sg\/wp-content\/uploads\/sites\/5\/2024\/07\/Stefan-Ballmer-pic-1.jpg\" class=\"attachment-full size-full wp-image-37157\" alt=\"\" srcset=\"https:\/\/www.physics.nus.edu.sg\/wp-content\/uploads\/sites\/5\/2024\/07\/Stefan-Ballmer-pic-1.jpg 1920w, https:\/\/www.physics.nus.edu.sg\/wp-content\/uploads\/sites\/5\/2024\/07\/Stefan-Ballmer-pic-1-300x169.jpg 300w, https:\/\/www.physics.nus.edu.sg\/wp-content\/uploads\/sites\/5\/2024\/07\/Stefan-Ballmer-pic-1-1024x576.jpg 1024w, https:\/\/www.physics.nus.edu.sg\/wp-content\/uploads\/sites\/5\/2024\/07\/Stefan-Ballmer-pic-1-768x432.jpg 768w, https:\/\/www.physics.nus.edu.sg\/wp-content\/uploads\/sites\/5\/2024\/07\/Stefan-Ballmer-pic-1-1536x864.jpg 1536w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Artist Impression of the Cosmic Explorer Corner Station (Eddie Anaya, Cal State Fullerton)<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-4a10bba elementor-reverse-tablet elementor-reverse-mobile elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"4a10bba\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-37526fc\" data-id=\"37526fc\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-78a6a1b elementor-widget__width-initial elementor-widget elementor-widget-image\" data-id=\"78a6a1b\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"412\" height=\"412\" src=\"https:\/\/www.physics.nus.edu.sg\/wp-content\/uploads\/sites\/5\/2024\/07\/Stefan-Ballmer.jpeg\" class=\"attachment-full size-full wp-image-37158\" alt=\"\" srcset=\"https:\/\/www.physics.nus.edu.sg\/wp-content\/uploads\/sites\/5\/2024\/07\/Stefan-Ballmer.jpeg 412w, https:\/\/www.physics.nus.edu.sg\/wp-content\/uploads\/sites\/5\/2024\/07\/Stefan-Ballmer-300x300.jpeg 300w, https:\/\/www.physics.nus.edu.sg\/wp-content\/uploads\/sites\/5\/2024\/07\/Stefan-Ballmer-150x150.jpeg 150w\" sizes=\"(max-width: 412px) 100vw, 412px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-39d79e6\" data-id=\"39d79e6\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-ff00f43 elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"ff00f43\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<h4>Biography<\/h4><p>Stefan Ballmer is a Professor of Physics and Director of the Center for Gravitational Wave Astronomy and Astrophysics at Syracuse University.
