Mass loss from massive globular clusters in tidal fields

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Yohai Meiron, Jeremy J. Webb, Jongsuk Hong, Peter Berczik, Rainer Spurzem | Summary: Massive globular clusters lose stars via internal and external processes. Internal processes include mainly two-body relaxation, while external processes include interactions with the Galactic tidal field. We perform a suite of N-body simulations of […]

Will LISA Detect Harmonic Gravitational Waves from Galactic Cosmic String Loops?

Kavli Affiliate: Craig J. Hogan | First 5 Authors: Zimu Khakhaleva-Li, Craig J. Hogan, , , | Summary: Rapid advancement in the observation of cosmic strings has been made in recent years placing increasingly stringent constraints on their properties, with $Gmulesssim 10^{-11}$ from Pulsar Timing Array (PTA). Cosmic string loops with low string tension clump […]

New bounds on macroscopic scalar-field topological defects from non-transient signatures due to environmental dependence and spatial variations of the fundamental constants

Kavli Affiliate: Yevgeny V. Stadnik | First 5 Authors: Yevgeny V. Stadnik, , , , | Summary: We point out that in models of macroscopic topological defects composed of one or more scalar fields that interact with standard-model fields via scalar-type couplings, the back-action of ambient matter on the scalar field(s) produces an environmental dependence […]

Quantifying the statistics of CMB-lensing-derived galaxy cluster mass measurements with simulations

Kavli Affiliate: Anthony Challinor | First 5 Authors: Íñigo Zubeldia, Anthony Challinor, , , | Summary: CMB lensing is a promising, novel way to measure galaxy cluster masses that can be used, e.g., for mass calibration in galaxy cluster counts analyses. Understanding the statistics of the galaxy cluster mass observable obtained with such measurements is […]

Quantum Algorithm for Approximating Maximum Independent Sets

Kavli Affiliate: Frank Wilczek | First 5 Authors: Hongye Yu, Frank Wilczek, Biao Wu, , | Summary: We present a quantum algorithm for approximating maximum independent sets of a graph based on quantum non-Abelian adiabatic mixing in the sub-Hilbert space of degenerate ground states, which generates quantum annealing in a secondary Hamiltonian. For both sparse […]

Measuring HERA’s primary beam in-situ: methodology and first results

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Chuneeta D. Nunhokee, Aaron R. Parsons, Nicholas S. Kern, Bojan Nikolic, Jonathan C. Pober | Summary: The central challenge in 21~cm cosmology is isolating the cosmological signal from bright foregrounds. Many separation techniques rely on the accurate knowledge of the sky and the instrumental response, including […]
