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: 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 […]

Kavli Affiliate: Keith Thompson | 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 frequency coverage and sensitivity to primordial B-mode polarization by an order of magnitude. The first receiver in the […]

Kavli Affiliate: Robert L. Byer | First 5 Authors: Zhexin Zhao, Kenneth J. Leedle, Dylan S. Black, Olav Solgaard, Robert L. Byer | Summary: Compressing electron pulses is important in many applications of electron beam systems. In this study, we propose to use optical beat notes to compress electron pulses. The beat frequency is chosen […]
