I copy below her abstract and the zoom connection.</div><div><div>She will talk about her work on black holes and also on her initiatives for increasing representation of women in STEMs as one of the founder of <a href="https://www.paritesciences.ca/en">Parité Science</a>. </div></div><div><br></div><div>This is unfortunately on the same day as the colloquium speaker from FRIB - but different topic!</div><div><br></div><div>If you'd like to meet her or share a meal, please sign up on her <a href="https://triumfoffice365-my.sharepoint.com/:w:/g/personal/cmalbrunot_triumf_ca/IQDlW-YC7YvSQ65Lan9dmY1dAWJPR63ZWFW92wfvmkRMPxA?e=XyjAct">agenda</a> for one or two slots.</div></div><div>Feel free to share will others who might be interested in meeting her.</div><div><br></div><div>Best</div><div>Chloé</div><div><br></div><div><br></div><div><div><b>New Frontiers: How Black Holes Shape the Largest Structures in the Universe</b></div><div><br></div><div>Galaxy clusters are the largest gravitational structures in the Universe—vast cities of hundreds to thousands of galaxies bound together by gravity. At their centers often reside supermassive black holes that, despite their small size, play a decisive role in shaping both their host galaxies and the surrounding cluster environment.</div><div><br></div><div>In this talk, I will show how these black holes influence galaxy clusters through powerful, jet-driven outflows that heat the surrounding gas, generate shock fronts and cosmic “sound waves,” and stir gas on enormous scales. Rather than simply disrupting their surroundings, this energy regulates how gas cools and flows, controls galaxy growth, and redistributes material and chemical elements across the cluster. In this sense, black holes act as the beating hearts of galaxies and clusters.</div><div><br></div><div>I will then present recent breakthroughs, including the first observations from the XRISM X-ray space telescope. XRISM enables, for the first time, direct measurements of the motions and turbulence of hot gas in clusters, opening a new window onto how black hole energy propagates through the intracluster medium. Finally, I will connect these observations to state-of-the-art cosmological simulations that recreate entire galaxy clusters, revealing how black holes have shaped the cosmic landscape over billions of years.</div><div><br></div><div>Lastly, I will introduce Parité sciences, a bold and game-changing initiative advancing gender parity in STEM by equipping educators with research-based tools to foster inclusive learning environments. </div></div><div><br></div><div><br></div><div>Zoom: </div><div><a href="https://ubc.zoom.us/j/62452933197?pwd=tsW3pDdkmD6yQyErZTi3oPVemuuaIw.1">https://ubc.zoom.us/j/62452933197?pwd=tsW3pDdkmD6yQyErZTi3oPVemuuaIw.1</a></div><div><br></div><div>Meeting ID: 624 5293 3197</div><div>Passcode: 051773</div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div><div><div dir="auto" style="caret-color: rgb(0, 0, 0);
