The group is both broad and deep, with thirteen senior researchers including eight faculty (Patrick Brady, Philip Chang, Jolien Creighton, Dawn Erb, David Kaplan, Lia Medeiros, Sarah Vigeland, and Alan Wiseman), two Distinguished Professors Emeriti (John Friedman and Leonard Parker), one Adjunct Professor (Bruce Allen), and one Visiting Scientist (Maria Alessandra Papa). The researchers are joined by research scientists, postdoctoral research associates, as well as graduate and undergraduate students.<\/p>\n\n\n\n<p>By bringing together expertise in gravitational physics, observations, data analysis, and computing, they address scientific challenges in relativistic astrophysics, time-domain astrophysics, gravitational-wave\/multi-messenger astronomy, galaxy formation\/evolution, and cosmology. Members of the CGCA participate in numerous large-scale collaborative efforts including:<\/p>\n\n\n\n<ul class=\"wp-block-list uwm-c-link--external\">\n<li><a href=\"https:\/\/www.ligo.org\/\"><strong>The Laser Interferometer Gravitational-Wave Observatory<\/strong><\/a><\/li>\n\n\n\n<li><a href=\"http:\/\/nanograv.org\/\"><strong>The North American Nanohertz Observatory for Gravitational Waves<\/strong><\/a><\/li>\n\n\n\n<li><a href=\"http:\/\/www.mwatelescope.org\/\"><strong>The Murchison Widefield Array<\/strong><\/a><\/li>\n\n\n\n<li><a href=\"http:\/\/growth.caltech.edu\/\"><strong>Global Relay of Observatories Watching Things Happen<\/strong><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.atnf.csiro.au\/projects\/askap\/index.html\"><strong>The Australian Square Kilometre Array Pathfinder<\/strong><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.ptf.caltech.edu\/ztf\"><strong>The Zwicky Transient Facility<\/strong><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/eventhorizontelescope.org\/\"><strong>The Event Horizon Telescope<\/strong><\/a><\/li>\n<\/ul>\n\n\n\n<p>CGCA members were directly involved in the first-ever discovery of gravitational waves in 2015, and in the discovery and follow-up of gravitational waves from two neutron stars in 2017.<\/p>\n<\/div>\n\n\n\n<div class=\"uwm-l-col uwm-l-col--4 uwm-l-offset--1\"><nav aria-label=\"Sidebar\" class=\"uwm-p-navigation-list uwm-p-navigation-list--gold-border \"><div class=\"uwm-p-navigation-list--title\"><a href=\"https:\/\/uwm.edu\/physics\/research\/\">Research<\/a><\/div><ul><li><a class=\"current\" href=\"https:\/\/uwm.edu\/physics\/research\/astronomy-gravitation-cosmology\/\"><span aria-current=\"page\">Astronomy, Gravitation &amp; Cosmology Research<\/span><\/a><\/li><li><a href=\"https:\/\/uwm.edu\/physics\/research\/biophysics-biomedical-imaging\/\">Biophysics &amp; Biomedical Imaging Research<\/a><\/li><li><a href=\"https:\/\/uwm.edu\/physics\/research\/condensed-matter-surface-physics\/\">Condensed Matter &amp; Surface Physics Research<\/a><\/li><li><a href=\"https:\/\/uwm.edu\/physics\/students\/undergraduate\/undergraduate-research-opportunities\/\">Undergraduate Research Opportunities<\/a><\/li><\/ul><\/nav><\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-faculty-research\">Faculty Research<\/h2>\n\n\n\n<div class=\"uwm-p-card-grid uwm-l-grid uwm-l-grid--equal-y uwm-l-grid--3\">\n<div class=\"uwm-p-card uwm-p-card--gold uwm-u-mb-40\"><div class=\"uwm-p-card--body\"><div class=\"uwm-p-card--content\"><div class=\"facetwp-template\"><div id=\"uwmpeople-container\" class=\"uwmpeople-grid\"><div id=\"uwmpeople-grid\" class=\"uwm-l-grid uwm-l-grid--1 uwm-u-mb-60\" aria-hidden=\"false\"><div class=\"uwmpeople-person uwm-l-grid uwm-u-mb-40\" data-catlist=\"88, 87\"><div class=\"people-image\"><a href=\"https:\/\/uwm.edu\/physics\/about\/directory\/brady-patrick\/\"><img decoding=\"async\" class=\"attachment-medium size-medium wp-post-image\" src=\"https:\/\/web.uwm.edu\/ls-people\/file\/prbrady.webp?ver=\" sizes=\"(max-width: 250px) 100vw, 250px\" width=\"300\" \/><\/a><\/div><div class=\"people-info\"><div class=\"people-name\"><strong><a href=\"https:\/\/uwm.edu\/physics\/about\/directory\/brady-patrick\/\">Patrick Brady<\/a><\/strong><\/div><div class=\"uwm-u-my-0\"><ul class=\"people-title-dept uwm-c-list--cleanlist\"><li><strong>Professor<\/strong>, <em>Physics<\/em><\/li><\/ul><\/div><ul class=\"people-contact uwm-c-list--cleanlist\"><li class=\"people-email\"><a href=\"mailto:prbrady@uwm.edu\">prbrady@uwm.edu<\/a><\/li><li class=\"people-phone\"><a href=\"tel:4142296508\">414-229-6508<\/a><\/li><\/ul><\/div><\/div><\/div><\/div><\/div>\n\n\n\n<p><strong>Patrick Brady\u2019s&nbsp;<\/strong>research interests include the dynamics of gravitational collapse, black holes, numerical relativity including simulation of binary coalescence, the detection of gravitational waves using interferometric gravitational-wave detectors, and multi-messenger studies of gravitational wave sources.
