In this talk\, I will argue that this makes the distribution of dark matter our only positive signal — and that mapping it precisely may be our most direct route to understanding what dark matter is. Galactic dynamics is no longer data-limited but model-limited\, and the assumption most in need of revision\, underlying nearly all of our models\, is that galaxies are in equilibrium. I will present recent work leveraging Gaia DR3 that reveals a declining stellar rotation curve\, show how underestimated errors in Jeans modeling bias these results\, and how simulations let us build a more robust treatment that avoids tensions with other probes of the density profile. I will then turn to dwarf galaxies\, where the kinematic data will not substantially improve and only better inference can extract the physics: I will present GraphNPE\, a graph neural network method that recovers dark matter density profiles from sparse stellar kinematics\, revealing a hint of a core in Boötes I\, consistent with self-interacting dark matter. Finally\, I will turn to the local velocity distribution\, where the Milky Way's merger history imprints substructure that the Standard Halo Model does not capture\, and use mutual information to show that this history is itself progressively erased from stellar dynamics — setting a fundamental limit on what the Galaxy can ever tell us. Together\, these results outline a program of inference that assumes no more than the data supports and extracts no less than it contains\, arriving just as Gaia DR4 and the next generation of spectroscopic surveys come online.

More like Besssssel Functions\, amirite? DESCRIPTION:What do ssssslithering snakes and spilling coffee have in common? A lot more than you might think! Earlier this month\, the Ig Nobel Prize honored quirky research results that “first make people laugh\, and then make them think.” In this talk\, we will explore how special functions known as Bessel functions unexpectedly appear in research done by Ig Nobel laureates. We will center our mathematical analysis around the problems of limbless locomotion and walking while holding a cup of coffee. The talk will also highlight the Ig Nobel prizes of this year as well as other Ig Nobel oddities of mathematical interest!

You will receive an engaging and comprehensive overview of the program\, as well as guidance for the application process. Sessions are hosted on different days and times to accommodate as many students as possible\, and you only need to attend one session before you apply.These information sessions are for students who area currently University of Michigan students.

Unlike the standard Benjamin-Ono equation\, the modified version is not known to be completely integrable\, so we cannot rely on integrable systems tools. First\, to manage the nonlocal Hilbert transform in the linear part of the equation\, we split it using positive and negative frequency projections. We then combine wave packet testing of Ifrim and Tataru\, the Klainerman–Sobolev vector field method\, a normal form transformation\, and a bootstrap argument\, to establish a global-in-time dispersive decay estimate.\n\n*To request access to the Zoom room\, please contact Nathan Hayford at nhayford [ at ] umich.edu.* UID:152174-21913177@events.umich.edu URL:https://events.umich.edu/event/152174 CLASS:PUBLIC STATUS:CONFIRMED CATEGORIES:Mathematics,Virtual,seminar LOCATION:Off Campus Location CONTACT: END:VEVENT BEGIN:VEVENT DTSTAMP:20260828T142508 DTSTART;TZID=America/Detroit:20260928T160000 DTEND;TZID=America/Detroit:20260928T180000 SUMMARY:Lecture / Discussion:Ottoman Greek Settlement in the Mitten State DESCRIPTION:Dr. Topalidis will present the historical events surrounding the migration and settlement of Ottoman Greeks in Michigan. The lecture will contextualize these events through the lens of Social Memory Theory and emphasize the erasure of migrant and refugee identity writ large. To achieve this\, the lecture will combine macro-level findings from extant scholarship with micro-level novel evidence from the Ottoman Greeks of the United States Digital History Project at Flagler College. \n\nThe lecture will cover the following subjects:\n• The displacement of Ottoman Greek migrants from their communities during World War I and the Greco-Turkish War.\n• Experiences of Ottoman Greek migrants fleeing from the cities of Izmir\, Ordu\, Şarköy\, Semendire\, and Ürgüp.\n• Experiences of Ottoman Greeks during their settlement in Michigan.\n• Experiences of second- and third-generation descendants of Ottoman Greeks during their formative years in Michigan.\n\nDr. Yiorgo Topalidis received a doctorate in Sociology from the University of Florida in 2022. Yiorgo’s research interests are emigration from the Ottoman Empire to the US and White identity construction\, contestation\, and transgenerational memory transfer. He is currently working on a monograph that explores the social construction of Ottoman Greek migrant identity in an early-20th-century U.S. context as a case study for decoupling Whiteness from White supremacist Whiteness.
