LightAMR format standard and lossless compression algorithms for adaptive mesh refinement grids: RAMSES use case
Loïc Strafella, Damien Chapon
The evolution of parallel I/O library as well as new concepts such as 'in transit' and 'in situ' visualization and analysis have been identified as key technologies to circumvent I…
Formation of compact galaxies in the Extreme-Horizon simulation
Solène Chabanier, Frédéric Bournaud, Yohan Dubois +18
We present the Extreme-Horizon (EH) cosmological simulation: EH models galaxy formation with stellar and AGN feedback and uses a very high resolution in the intergalactic and circu…
Boosting I/O and visualization for exascale era using Hercule: test case on RAMSES
Loic Strafella, Damien Chapon
It has been clearly identified that I/O is one of the bottleneck to extend application for the exascale era. New concepts such as 'in transit' and 'in situ' visualization and analy…
A sub-parsec resolution simulation of the Milky Way: Global structure of the ISM and properties of molecular clouds
F. Renaud, F. Bournaud, E. Emsellem +9
We present a self-consistent hydrodynamical simulation of a Milky Way-like galaxy, at the resolution of 0.05 pc. The model includes star formation and a new implementation of stell…
Beyond the nuclear starburst? Clustered star formation in major mergers
Leila C. Powell, Frederic Bournaud, Damien Chapon +1
Recent simulation work has successfully captured the formation of the star clusters that have been observed in merging galaxies. These studies, however, tend to focus on studying e…
Volume Rendering of AMR Simulations
Marc Labadens, Daniel Pomarède, Damien Chapon +4
High-resolution simulations often rely on the Adaptive Mesh Resolution (AMR) technique to optimize memory consumption versus attainable precision. While this technique allows for d…
Hydrodynamics of galaxy mergers with supermassive black holes: is there a last parsec problem ?
Damien Chapon, Lucio Mayer, Romain Teyssier
We study the formation of a supermassive black hole (SMBH) binary and the shrinking of the separation of the two holes to sub-pc scales starting from a realistic major merger betwe…
The impact of ISM turbulence, clustered star formation and feedback on galaxy mass assembly through cold flows and mergers
Leila C. Powell, Frederic Bournaud, Damien Chapon +3
Two of the dominant channels for galaxy mass assembly are cold flows (cold gas supplied via the filaments of the cosmic web) and mergers. How these processes combine in a cosmologi…
Star formation in galaxy mergers: ISM turbulence, dense gas excess, and scaling relations for disks and starbusts
Frederic Bournaud, Leila C. Powell, Damien Chapon +1
Galaxy interactions and mergers play a significant, but still debated and poorly understood role in the star formation history of galaxies. Numerical and theoretical models cannot…
Galactic star formation in parsec-scale resolution simulations
Leila C. Powell, Frederic Bournaud, Damien Chapon +3
The interstellar medium (ISM) in galaxies is multiphase and cloudy, with stars forming in the very dense, cold gas found in Giant Molecular Clouds (GMCs). Simulating the evolution…
The driving mechanism of starbursts in galaxy mergers
Romain Teyssier, Damien Chapon, Frederic Bournaud
We present hydrodynamic simulations of a major merger of disk galaxies, and study the ISM dynamics and star formation properties. High spatial and mass resolutions of 12pc and 4x10…
Hydrodynamics of high-redshift galaxy collisions: From gas-rich disks to dispersion-dominated mergers and compact spheroids
Frederic Bournaud, Damien Chapon, Romain Teyssier +7
Disk galaxies at high redshift (z~2) are characterized by high fractions of cold gas, strong turbulence, and giant star-forming clumps. Major mergers of disk galaxies at high redsh…
