In the Solar system, the planets follow orbits that are nearly aligned with the Sun's equatorial plane. What about planets around other stars? Many techniques are available to measure the obliquities of planet-hosting stars, ranging from an effect...

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...

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...

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...
