Probing the Outskirts of the Early Stage Galaxy Cluster Merger A1750
Esra Bulbul, Scott W. Randall, Matthew Bayliss +12
We present results from recent Suzaku and Chandra X-ray, and MMT optical observations of the strongly merging "double cluster" A1750 out to its virial radius, both along and perpen…
PAPER-64 Constraints On Reionization II: The Temperature Of The z=8.4 Intergalactic Medium
Jonathan C. Pober, Zaki S. Ali, Aaron R. Parsons +24
We present constraints on both the kinetic temperature of the intergalactic medium (IGM) at z=8.4, and on models for heating the IGM at high-redshift with X-ray emission from the f…
PAPER-64 Constraints on Reionization: The 21cm Power Spectrum at z=8.4
Zaki S. Ali, Aaron R. Parsons, Haoxuan Zheng +20
In this paper, we report new limits on 21cm emission from cosmic reionization based on a 135-day observing campaign with a 64-element deployment of the Donald C. Backer Precision A…
New Limits on Polarized Power Spectra at 126 and 164 MHz: Relevance to Epoch of Reionization Measurements
David Moore, James E. Aguirre, Saul Kohn +15
Polarized foreground emission is a potential contaminant of attempts to measure the fluctuation power spectrum of highly redshifted 21 cm HI emission from the epoch of reionization…
Galaxy Cluster Pressure Profiles as Determined by Sunyaev Zel'dovich Effect Observations with MUSTANG and Bolocam I: Joint Analysis Technique
Charles Romero, Brian S. Mason, Jack Sayers +11
We present a technique to constrain galaxy cluster pressure profiles by jointly fitting Sunyaev-Zel'dovich effect (SZE) data obtained with MUSTANG and Bolocam for the clusters Abel…
