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…
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…
The impact of supernovae driven winds on stream-fed protogalaxies
Leila C. Powell, Adrianne Slyz, Julien Devriendt
SNe driven winds are widely thought to be very influential in the high-redshift Universe, shaping the properties of the circum-galactic medium, enriching the IGM with metals and dr…
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…
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…
The relationship between substructure in 2D X-ray surface brightness images and weak lensing mass maps of galaxy clusters: A simulation study
Leila C. Powell, Scott T. Kay, Arif Babul
In this paper, we undertake a study to determine what insight can be reliably gleaned from the comparison of the X-ray and the weak lensing mass maps of galaxy clusters. We do this…
Investigating the Relationship Between the Hot Gas and the Dark Matter Components of Galaxy Clusters
Leila C. Powell, Scott T. Kay, Arif Babul +1
Various differences in galaxy cluster properties derived from X-ray and weak lensing observations have been highlighted in the literature. One such difference is the observation of…
The Sunyaev-Zel'dovich temperature of the intracluster medium
Scott T. Kay, Leila C. Powell, Andrew R. Liddle +1
The relativistic Sunyaev-Zel'dovich (SZ) effect offers a method, independent of X-ray, for measuring the temperature of the intracluster medium (ICM) in the hottest systems. Here,…
