A large number of close-in super-Earths have now been
discovered. These planets are most likely formed while the
proto-planetary disks are still alive, hence the title of this
talk. I will report some recent observational results, regarding
their...
I will describe my work, all joint with D. Gaiotto and some also
joint with E. Witten, to understand the homotopy type of the space
of (1+1)d N=(0,1) SQFTs --- what a condensed matter theorist would
call "phases" of SQFTs. Our motivating hypothesis...
We describe the coupling of holomorphic Chern-Simons theory at
large N with Kodaira-Spencer gravity. This gives a complete
description of open-closed string field theory in the topological
B-model. We explain an anomaly cancellation mechanism at all...
CHIME is a new interferometric telescope at radio frequencies
400-800 MHz. The mapping speed (or total statistical power) of
CHIME is among the largest of any radio telescope in the world, and
the technology powering CHIME could be used to build...
New and improved observational facilities are sampling the night
sky with unprecedented temporal cadence and sensitivity across the
electromagnetic spectrum. This exercise led to the discovery of new
types of astronomical transients and...
We analyze modular invariance drawing inspiration from
tauberian
theorems. Given a modular invariant partition function with a
positive
spectral density, we derive lower and upper bounds on the number
of
operators within a given energy interval. They...
I will discuss time-dependent probes of the renormalization
group, and derive new constraints that govern the spread of local
operators in holographic theories. The same methods lead to sum
rules for inflationary correlators, relating observables...
Red supergiants (RSGs) are the helium-fusing descendants of
moderately massive (10-25Mo) stars. As the coldest and largest (in
physical size) members of the massive star population, these
evolved stars serve as ideal "magnifying glasses" for...
Several lines of evidence, both theoretical and observational,
indicate that additional planets in the outer solar system remain
to be discovered. Most recently, attention has been focused on
'Planet Nine',a few Earth mass planet with a moderate...
When absorbing boundary conditions are used to evaporate a black
hole in AdS/CFT, we show that there is a phase transition in the
location of the quantum Ryu-Takayanagi surface, at precisely the
Page time. The new RT surface lies slightly inside the...
