The talk begins in 2005, with the unexpected discovery that
massive early-type galaxies were extremely compact at redshifts
z~2. It is now thought that the remarkable size growth of these
galaxies from z=2 to z=0 is largely due to minor mergers;
the...

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...
In the last few years of the lives of massive stars, fusion in
the core of the star produces a nuclear power that greatly exceeds
the Eddington luminosity. This drives vigorous convection in
numerous core and shell burning phases. I describe the...

Concinnitas is a collection of ten aquatints curated by Dan Rockmore and produced from the contributions of ten mathematicians and physicists in response to the prompt to transcribe their “most beautiful mathematical expression.” In this video from 2015, Robbert Dijkgraaf, Director and Leon Levy Professor, moderates a talk and Q&A with two contributors to Concinnitas, Enrico Bombieri and Freeman Dyson, as well as the portfolio curator, Dan Rockmore.
Richard Schwartz, Member (2003–04) in the School of Mathematics and
the Chancellor’s Professor of Mathematics at Brown University, will
talk about really large numbers, as well as the different sizes of
infinity and the different forms of infinite...
Environment plays a major in role in the evolution of galaxies.
This is particularly true of low mass dwarf galaxies where more
massive galaxies dramatically affect the local gravitational
potential. Isolated galaxies offer a unique test bed for...
Cosmic rays comprise only about one billionth of interstellar
particles in the Milky Way, but have as much energy as the thermal
gas. Low energy cosmic rays affect the chemistry and thermodynamics
of interstellar through collisional processes...
Recent results from Kepler and ground-based exoplanet surveys
suggest that low-mass stars are host to numerous small planets.
Since low-mass stars are intrinsically faint at optical
wavelengths, obtaining the Doppler precision necessary to detect...
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...
