SUMMARY:Presentation:From clouds to streams: Modeling the lifecycle of star clusters
DESCRIPTION:Abstract:\n \nStar clusters play a key role in structure formation because they mark a fundamental transition from structures governed by gravity to those driven by the complex physics of baryons. They emerge from giant molecular clouds assembled through the fragmentation and collapse of gas within galaxies. Massive clusters formed in the early Universe may survive to the present day as globular clusters\, which are fossils of early galaxy assembly. Less massive clusters\, on the other hand\, gradually lose stars via tidal disruption and ultimately dissolve into stellar streams that populate galactic stellar halos. Cluster formation\, migration\, and dynamical evolution are governed by different physical processes operating on distinct spatial and time scales. These enormous dynamical ranges prevent theorists from building a purely analytical framework describing the complete lifecycle of star clusters.\n\nNumerical modeling provides a powerful tool for disentangling this complexity. However\, no single model can resolve all relevant scales\, and constructing a unified framework remains an ongoing challenge. This dissertation presents my contributions toward such a framework. I first developed a semi-analytical model applied to cosmological simulations\, where clusters are tagged to simulation particles to follow their migration through galaxies. The model reproduces the chemical\, spatial\, and kinematic properties of cluster populations across a broad range of galaxy masses. To improve its prescription for dynamical disruption\, I developed a particle-spray algorithm calibrated against direct N-body simulations to trace the distribution of escaping stars. Based on this algorithm\, I developed an automated stellar stream-detection method designed to achieve both high purity and high completeness. Because streams are stellar debris of dynamical mass loss\, balancing both quantities is important for obtaining unbiased measurements of cluster mass loss rates.\n\nLooking forward\, parsec-resolution hydrodynamic simulations\, combined with deep space-based observations\, will constrain cluster formation in early galaxies\, while larger stream samples from next-generation wide-field surveys will improve models of dynamical evolution. Together\, these advances will ultimately connect the birth of clusters in the earliest galaxies to the surviving clusters and stellar streams observed today.

SUMMARY:Workshop / Seminar:In-person Arabic Placement test_August 13\, 2026 (10am-1pm EST)
DESCRIPTION:Welcome to the Arabic Placement TestAbout the testThe test takes approximately three hours in length\, and it is composed of three portions:a. The writing portion is completed via Zoom and it is worth a total of 100 points.b. The reading portion is completed online through Canvas site\, and it is worth a total of 48 points.c. Right after finishing with the reading portion\, each student will have a follow-up interview with a proctor. The interviews last approximately 15 minutes and it is worth a total of 20 points.Important: a. Students who receive 60% or above will be placed in Arabic 401 and thus placed out of the LSA Language Requirement.b. Students who are not able to write in Modern Standard Arabic (MSA) do not need to take the placement test and they will be advised to enroll in Arabic 101.Where can I view my results?a. Placement results are posted within 7 business days after the test.b. You will not be notified of your score automatically. c. You may view your placements via: Wolverine Access > Student Business > Academic Records > View Placement Exam Results.\nImportant information about the test* Placements are valid for only one year. If you fail to register in the course that you are placed in\, you will be required to retake the test.* Retaking the placement test is only permitted after the placement results expire.* Students who are currently taking an Arabic course will not be allowed to take the placement test. * Students who took or are currently enrolled in an Arabic course are not eligible to take the Arabic placement test. They should register for the next course level.* The test assesses students’ proficiency in Modern Standard Arabic (MSA)\, NOT colloquial Arabic.  * If you speak an Arabic dialect but you do not know how to read or write or have little knowledge\, feel free to register in Arabic 101.* Students who know some Arabic because they came from an Arabic-speaking household or have studied Arabic before\, must take the Arabic proficiency test in order to determine their placement.* Students who have taken Arabic at other institutions and wish to continue their Arabic study at UM must take the placement test to determine their level. Credits for Arabic study undertaken at another institution prior to joining UM or in a summer program while attending UM\, transfer in as generic departmental credits and students must take the placement test to determine credit equivalencies to UM courses.* If you place in or beyond the 401 level\, you will have satisfied the LSA language requirement. * Students are encouraged to take a placement test as early as possible in their studies in order to determine the level they should enroll in\, or if they test out of the language requirement. This is extremely important to avoid delays in graduation and complications with placement.* Arabic 101\, 201\, 401\, 501 are offered ONLY in the Fall semester\, and Arabic 102\, 202\, 402\, 504\, 511 are ONLY offered in the Winter semester.* Arabic 103 (the equivalent of Arabic 101 & 102\, combined) AND Arabic 203 (the equivalent of Arabic 201 & 202\, combined) are offered in the Spring-Summer terms.\nUM’s Arabic curriculum is a dual register curriculum in which students learn to speak and understand the Levantine dialect (the dialect of Jordan\, Syria\, Palestine and Lebanon) in addition to developing the four language skills of formal Arabic (fuSHa). \nIf you have questions regarding the placement test\, please contact the program director at\, mesarabicprogram@umich.edu.\n
