SALT spectroscopic observations of galaxy clusters detected by ACT and a Type II quasar hosted by a brightest cluster galaxy
Brian Kirk, Matt Hilton, Catherine Cress +20
We present Southern African Large Telescope (SALT) follow-up observations of seven massive clusters detected by the Atacama Cosmology Telescope (ACT) on the celestial equator using…
The Atacama Cosmology Telescope: Cosmological parameters from three seasons of data
Jonathan L. Sievers, Renée A. Hlozek, Michael R. Nolta +90
We present constraints on cosmological and astrophysical parameters from high-resolution microwave background maps at 148 GHz and 218 GHz made by the Atacama Cosmology Telescope (A…
Evidence of Galaxy Cluster Motions with the Kinematic Sunyaev-Zel'dovich Effect
Nick Hand, Graeme E. Addison, Eric Aubourg +55
Using high-resolution microwave sky maps made by the Atacama Cosmology Telescope, we for the first time present strong evidence for motions of galaxy clusters and groups via microw…
The sensitivity of BAO Dark Energy Constraints to General Isocurvature Perturbations
S. Muya Kasanda, C. Zunckel, K. Moodley +2
Baryon Acoustic Oscillation (BAO) surveys will be a leading method for addressing the dark energy challenge in the next decade. We explore in detail the effect of allowing for smal…
Non-standard morphological relic patterns in the cosmic microwave background
Joe Zuntz, James P. Zibin, Caroline Zunckel +1
Statistically anomalous signals in the microwave background have been extensively studied in general in multipole space, and in real space mainly for circular and other simple patt…
Measuring Portfolio Diversification
Ulrich Kirchner, Caroline Zunckel
In the market place, diversification reduces risk and provides protection against extreme events by ensuring that one is not overly exposed to individual occurrences. We argue that…
