ZFIRE: Similar Stellar Growth in H-emitting Cluster and Field Galaxies at z~2
Kim-Vy H. Tran, Leo Y. Alcorn, Glenn G. Kacprzak +13
We compare galaxy scaling relations as a function of environment at with our ZFIRE survey where we have measured H fluxes for 90 star-forming galaxies selected from a m…
Radial Distribution Of ISM Gas-phase Metallicity In CLASH Clusters at z~0.35: A New Outlook On Environmental Impact On Galaxy Evolution
Anshu Gupta, Tiantian Yuan, Kim-Vy H. Tran +3
We present the first observation of cluster-scale radial metallicity gradients from star-forming galaxies. We use the DEIMOS spectrograph on the Keck II telescope to observe two CL…
Mass modeling of galaxy clusters: quantifying hydrostatic bias and contribution from non-thermal pressure
Davide Martizzi, Harrison Agrusa
Galaxy cluster mass determinations achieved using X-ray and Sunyaev-Zel'dovich data combined with the assumption of hydrostatic equilibrium are generally biased. The bias exists fo…
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…
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…
