The interpretation of low-redshift galaxy surveys is more
complicated than the interpretation of CMB temperature
anisotropies. First, the matter distribution evolves nonlinearly at
low redshift...
Galaxy formation is a complex, hierarchical, highly non-linear
process, which involves gravitational collapse of dark matter and
baryons, supersonic, highly compressible and turbulent flows of
gas, star formation, stellar feedback, as well as...
In this lecture, Tegmark surveys how humans have repeatedly
underestimated not only the size of the cosmos, but also the power
of the human mind to understand it using mathematical equations. He
explores how mathematics in physics has allowed us to...
Jo Bovy, John N. Bahcall Fellow in the School of Natural Sciences,
talks about stars, planets, and gases that make up galaxies, the
dark matter that holds them together, and the history of our own
Milky Way galaxy in this talk geared for children...
The last decades have seen great advances in our understanding of
the history of our universe. I will summarize our current
knowledge, describe some of the puzzles that still remain and
speculate about future developments in cosmology. Matias...
The increasing role of general relativity in the dynamics of
stellar systems with central massive black holes, in the generation
of extreme mass-ratio inspirals, and in the evolution of
hierarchical triple systems inspires a close examination of
how...
Planetesimals are the building blocks of planets. They can be
traced by the dust they produce in collisions or sublimation that
forms a debris disk. In the solar system, such a dust disk is
produced by the asteroids, comets and Kuiper Belt objects...
We know that most stars, if not all, were once surrounded by
protoplanetary disks. How these young disks evolve into planetary
systems is a fundamental question in astronomy. Observations of T
Tauri stars (TTS) may provide insights into this...
