Abstract: I will describe a few classes of solutions to the Einstein equations whose metrics are singular or highly oscillatory, and discuss the relation between them. The singular solutions include as special examples impulsive gravitational waves and null dust shell solutions.

Neutron stars are by far the strongest known magnets in the universe. Some of them (called magnetars) generate explosions by suddenly dissipating magnetic energy with a rate up to $10^{47}$ erg/s. These magnetic explosions emit giant gamma-ray flares observed in our and neighboring galaxies.

The Princeton Center for Complex Materials (PCCM) and the Princeton Institute for the Science and Technology of Materials (PRISM) co-sponsor a seminar series that is held on Wednesdays throughout the semester.

Cells across the tree of life respond to a sudden, nonlethal rise in temperature--heat shock--in similar ways. Following heat shock, proteins and mRNAs form clumps, certain genes turn on, and protein synthesis and cell growth sharply decline.

Adri Duivenvoorden, Zack Li, Brandon Hensley, Jo Dunkley, and Lyman Page will update us on the status of the Atacama Cosmology Telescope (ACT).

Abstract:

Are you considering applying to a physics graduate program? Did you know that you get paid to be a grad student? Ph.D. programs in STEM fields are full-time jobs with all the benefits: no tuition and getting paid to research and learn!
