Compact mass-spring models can measure remarkably small
deformations while conserving angular momentum. We use them within
an N-body code to simulate tidal evolution of viscoelastic spinning
objects, tying simulated rheology to spin dynamics...
The Vera C. Rubin Observatory Legacy Survey of Space and Time
(LSST) will produce several billion photometric redshifts
(photo-z's), enabling cosmological analyses to select a
subset of galaxies with the most accurate photo-z.
We perform initial...
The origin of hot (and warm) Jupiters has been an open question
since the beginning of the exoplanet era. These planets are
unlikely to have formed on the orbits we currently observe and
several migration theories have been proposed to explain
them...
A better understanding of the complex galaxy formation, in
particular the co-evolution of galaxies and dark matter halos, will
directly enable us to translate astrophysical observations into
solid constraints on the physical properties of dark...
I will present a recent numerical study on the generation and
the amplification of magnetic fields in the Universe. Through
cosmological simulations of galaxy formation, we have studied the
Biermann battery process that drives microscopic current...
The WIND satellite has been collecting magnetic fields at 92-ms
and plasma moments at 3-s cadence in the pristine solar wind over
nearly two full solar cycles, since it was launched on 1 Nov 1994.
We report on the statistical properties in and...
Dark matter halos are the fundamental building blocks of cosmic
large-scale structure. Improving our theoretical understanding of
their evolution and formation is an essential step towards
understanding how galaxies form. I will present a deep...
Kinetic plasma physics is an integral, but often neglected,
component of many high-energy astrophysical systems. Understanding
the dynamics and energization processes in collisionless plasmas is
essential for interpreting the observable radiation...
