Kavli Affiliate: Tom Abel | First 5 Authors: Yunchong Wang, Arka Banerjee, Tom Abel, ., | Summary: Distances to the $k$-nearest-neighbor ($k$NN) data points from volume-filling query points are a sensitive probe of spatial clustering. Here we present the first application of $k$NN summary statistics to observational clustering measurement, using the 1000 richest redMaPPer clusters […]

Kavli Affiliate: Roger D. Blandford | First 5 Authors: Elena M. Murchikova, Tianshu Wang, Brian Mason, Roger D. Blandford, | Summary: Murchikova et al 2019 discovered a disk of cool ionized gas within 20,000 Schwarzschild radii of the Milky Way’s Galactic Center black hole Sagittarius A*. They further demonstrated that the ionizing photon flux in […]

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: John F. Wu, J. E. G. Peek, Erik J. Tollerud, Yao-Yuan Mao, Ethan O. Nadler | Summary: We present "Extending the Satellites Around Galactic Analogs Survey" (xSAGA), a method for identifying low-$z$ galaxies on the basis of optical imaging, and results on the spatial distributions of […]

Kavli Affiliate: C. L. Kuo | First 5 Authors: J. P. Filippini, A. E. Gambrel, A. S. Rahlin, E. Y. Young, P. A. R. Ade | Summary: Experiments deploying large arrays of transition-edge sensors (TESs) often require a robust method to monitor gain variations with minimal loss of observing time. We propose a sensitive and […]

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Nickolas Kokron, Joseph DeRose, Shi-Fan Chen, Martin White, Risa H. Wechsler | Summary: We investigate the stochastic properties of typical red galaxy samples in a controlled numerical environment. We use Halo Occupation Distribution (HOD) modelling to create mock realizations of three separate bright red galaxy samples […]

Kavli Affiliate: C. L. Kuo | First 5 Authors: A. Schillaci, P. A. R. Ade, Z. Ahmed, M. Amiri, D. Barkats | Summary: The BICEP/Keck Collaboration is currently leading the quest to the highest sensitivity measurements of the polarized CMB anisotropies on degree scale with a series of cryogenic telescopes, of which BICEP Array is […]

Kavli Affiliate: Kent D. Irwin | First 5 Authors: Marion Dierickx, P. A. R. Ade, Zeeshan Ahmed, Mandana Amiri, Denis Barkats | Summary: The BICEP/Keck series of experiments target the Cosmic Microwave Background at degree-scale resolution from the South Pole. Over the next few years, the "Stage-3" BICEP Array (BA) telescope will improve the program’s […]
