Hydrodynamical simulations of Pinwheel nebula WR 104 [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractPinwheel Nebulae are colliding wind binaries (CWB) composed of a Wolf-Rayet star and an early-type star. We first compare our simulations to analytic solutions for CWB. Then we perform large scale 2D simulations of the particular system WR 104.

Coevolution of Dust and Chemistry in Galaxy Simulations with a Resolved Interstellar Medium
The Astrophysical Journal, 2023 Nearby dwarf irregular galaxies are ideal laboratories for studying the interstellar medium (ISM) at low metallicity, which is expected to be common for galaxies at very high redshift being observed by JWST. We present the first high-resolution (∼0.2 pc)

Energy decay in a granular gas collapse
New Journal of Physics, 2017 An inelastic hard ball bouncing repeatedly off the ground comes to rest in finite time by performing an infinite number of collisions. Similarly, a granular gas under the influence of external gravity, condenses at the bottom of the confinement due to ...

Measurement of the small-scale structure of the intergalactic medium using close quasar pairs
, 2017 The distribution of diffuse gas in the intergalactic medium (IGM) imprints a series of hydrogen absorption lines on the spectra of distant background quasars known as the Lyman-$\alpha$ forest.

Hydrodynamical Simulations of the IGM at High Mach Numbers [PDF]
, 2002 We present a new approach to doing Eulerian computational fluid dynamics that is designed to work at high Mach numbers encountered in hydrodynamical simulations of the IGM.

Hydrodynamic simulation of elliptic flow [PDF]
Nuclear Physics A, 1999 We use a hydrodynamic model to study the space-time evolution transverse to the beam direction in ultrarelativistic heavy-ion collisions with nonzero impact parameters. We focus on the influence of early pressure on the development of radial and elliptic flow.

Gravitational lenses in hydrodynamical simulations
Proceedings of the International Astronomical Union, 2022 AbstractThe gravitational lensing signal produced by a galaxy or a galaxy cluster is determined by its total matter distribution, providing us with a way to directly constrain their dark matter content. State-of-the-art numerical simulations successfully reproduce many observed properties of galaxies and can be used as a source of mock observations and

Hydrodynamical simulations of viscous overstability in Saturn's rings
, 2010 We perform axisymmetric hydrodynamical simulations that describe the nonlinear outcome of the viscous overstability in dense planetary rings. These simulations are particularly relevant for Cassini observations of fine-scale structure in Saturn's A and B-

Baryonic and dark matter distribution in cosmological simulations of spiral galaxies [PDF]
, 2014 We study three cosmological hydrodynamical simulations of Milky Way(MW)-sized halos including a comparison with the dark matter(DM)-only counterparts. We find one of our simulated galaxies with interesting MW-like features. Thanks to a consistently tuned
