PHEW: a parallel segmentation algorithm for three-dimensional AMR datasets - application to structure detection in self-gravitating flows
Andreas Bleuler, Romain Teyssier, Sébastien Carassou +1
We introduce PHEW (Parallel HiErarchical Watershed), a new segmentation algorithm to detect structures in astrophysical fluid simulations, and its implementation into the adaptive…
Baryonic effects on weak-lensing two-point statistics and its cosmological implications
Irshad Mohammed, Davide Martizzi, Romain Teyssier +1
We develop an extension of \textit{the Halo Model} that describes analytically the corrections to the matter power spectrum due to the physics of baryons. We extend these correctio…
Supernova Feedback in an Inhomogeneous Interstellar Medium
Davide Martizzi, Claude-Andre Faucher-Giguere, Eliot Quataert
Supernova (SN) feedback is one of the key processes shaping the interstellar medium (ISM) of galaxies. SNe contribute to (and in some cases may dominate) driving turbulence in the…
The VIMOS Public Extragalactic Redshift Survey (VIPERS). Measuring nonlinear galaxy bias at z~0.8
C. Di Porto, E. Branchini, J. Bel +46
We use the first release of the VImos Public Extragalactic Redshift Survey of galaxies (VIPERS) of ~50,000 objects to measure the biasing relation between galaxies and mass in the…
Brightest Cluster Galaxies in Cosmological Simulations with Adaptive Mesh Refinement: Successes and Failures
Davide Martizzi, Jimmy, Romain Teyssier +1
A large sample of cosmological hydrodynamical zoom-in simulations with Adaptive Mesh Refinement (AMR) is analysed to study the properties of simulated Brightest Cluster Galaxies (B…
A Globular Cluster Toward M87 with a Radial Velocity < -1000 km/s: The First Hypervelocity Cluster
Nelson Caldwell, Jay Strader, Aaron J. Romanowsky +4
We report the discovery of an object near M87 in the Virgo Cluster with an extraordinary blueshift of -1025 km/s, offset from the systemic velocity by >2300 km/s. Evaluation of pho…
