Research Interests

Dr. Mac Low's work focuses on understanding the formation of planets, stars, and galaxies. Working with students and colleagues, he has developed numerical models at different physical scales to attack these problems. At the smallest scales, he is studying the formation in protoplanetary disks of the millimeter-sized glassy beads known as chondrules that form half the mass of the most primitive Solar System meteorites. Still within these disks, he studies the formation of planetesimals from rocks, and the migration of planets through the gas disk. At scales of less than one light year, he has simulated the behavior of self-gravitating, supersonic, magnetized turbulence to understand the formation of the dense cloud cores in which protostars are observed, and has modeled the expansion of ionized regions in such turbulence.  At scales of hundreds to thousands of light years, he is studying the influence of multiple supernova explosions on the interstellar gas, and how clouds of star-forming molecular gas form.  Finally, at the galactic scale of tens of thousands of light years, he studies the large-scale formation of stars in galaxies. 

Dr. Mac Low serves as an advisor for the HPC facilities development and expansion. His research group relies on computational modeling using gas dynamical and magnetohydrodynamical (MHD) simulations to study the formation of planets, and stars, and the structure of the interstellar gas, with applications to galactic winds and galaxy formation.
