The clustered nature of star formation leaves a long-term
imprint on galaxies, stars, and planets. At young ages, stellar
clustering subdivides galaxies into individual building blocks
undergoing vigorous, feedback-driven life cycles that vary
with...
Star formation takes place in the densest and coldest parts of
the interstellar medium (ISM), in dark molecular clouds. These are
swept up by multiple supernova explosions on scales of several
hundred parsec. While condensing out of the warm ISM...
I discuss graviton non-Gaussianities in models of inflation
where de Sitter isometries are spontaneously broken. First, I
review the different symmetry breaking patterns following Nicolis,
Penco, Piazza, Rattazzi (2015), and discuss which of them...
The Milky Way is a unique testbed for theories of galaxy
formation and evolution. Especially the stellar halo is amenable to
studies into our galaxy’s past both because it contains some of the
oldest stars and because the dynamical timescales are...
Binary neutron star mergers provide a unique probe of the
neutron star equation of state (EOS) across a wide range of
parameter space, from the zero-temperature EOS during the inspiral
to the finite-temperature EOS following the merger. In this
talk...
NASA's Kepler mission conducted a large survey of planetary
systems. Recently, we have advanced from measuring occurrence
rates as a function of planet size and period to characterizing the
intrinsic distribution of planetary system
architectures. ...
Earth-based radar observations in 2006–2019 enable the first
measurement of the spin precession rate and moment of inertia of
Venus. The observations also show that the spin period of the solid
planet changes by tens of minutes. The length-of-day...
I will present the first results of the survey of all white
dwarfs (WD) that were observed in the Hobby-Eberly Telescope Dark
Energy Experiment (HETDEX) using the Visible Integral-field
Replicable Unit Spectrograph (VIRUS). The final outcome will
be...
A dark matter candidate lighter than about 30 eV exhibits wave
behavior in a typical galactic environment. Examples include the
QCD axion as well as other axion-like-particles. We review the
particle physics motivations, and discuss experimental and...
High-precision astrometric data from space observatories, such
as the Hubble Space Telescope (HST) and Gaia, are revolutionizing
our ability to study the Local Group. 6D phase space measurements
(3-dimensional position and velocity) now make it...
