Reionization on Large Scales III: Predictions for Low-ell Cosmic Microwave Background Polarization and High-ell Kinetic Sunyaev-Zel'dovich Observables
Nick Battaglia, Aravind Natarajan, Hy Trac +2
We present new predictions for temperature (on small angular scales) and polarization (on large angular scales) CMB anisotropies induced during the epoch of reionization (EoR). Usi…
Reionization on Large Scales I: A Parametric Model Constructed from Radiation-Hydrodynamic Simulations
Nick Battaglia, Hy Trac, Renyue Cen +1
We present a new method for modeling inhomogeneous cosmic reionization on large scales. Utilizing high-resolution radiation-hydrodynamic simulations with 2048^3 dark matter particl…
Nature of Lyman Alpha Blobs: Powered by Extreme Starbursts
Renyue Cen, Zheng Zheng
We present a new model for the observed Lyman alpha blobs (LABs) within the context of the standard cold dark matter model. In this model, LABs are the most massive halos with the…
Chandra View of the Warm-Hot IGM toward 1ES 1553+113: Absorption Line Detections and Identifications (Paper I)
F. Nicastro, M. Elvis, Y. Krongold +14
We present the first results from our pilot 500 ks Chandra-LETG Large Program observation of the soft X-ray brightest source in the z>=0.4 sky, the blazar 1ES 1553+113, aimed to se…
Comparisons of Cosmological MHD Galaxy Cluster Simulations to Radio Observations
Hao Xu, Federica Govoni, Matteo Murgia +6
Radio observations of galaxy clusters show that there are G magnetic fields permeating the intra-cluster medium (ICM), but it is hard to accurately constrain the strength and st…
Building galaxies by accretion and in-situ star formation
C. N. Lackner, R. Cen, J. P. Ostriker +1
We examine galaxy formation in a cosmological AMR simulation, which includes two high resolution boxes, one centered on a 3 \times 10^14 M\odot cluster, and one centered on a void.…
