Edge observables of the Maxwell-Chern-Simons theory

Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Bogar Díaz, Juan Margalef-Bentabol, Eduardo J. S. Villaseñor, | Summary: We analyze the Lagrangian and Hamiltonian formulations of the Maxwell-Chern-Simons theory defined on a manifold with boundary for two different sets of boundary equations derived from a variational principle. We pay special […]

Direct Optimal Mapping for 21cm Cosmology: A Demonstration with the Hydrogen Epoch of Reionization Array

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Zhilei Xu, Jacqueline N. Hewitt, Kai-Feng Chen, Hongguen Kim, Joshua S. Dillon | Summary: Motivated by the desire for wide-field images with well-defined statistical properties for 21cm cosmology, we implement an optimal mapping pipeline that computes a maximum likelihood estimator for the sky using the interferometric […]

A High-Time Resolution Search for Compact Objects using Fast Radio Burst Gravitational Lens Interferometry with CHIME/FRB

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Zarif Kader, Calvin Leung, Matt Dobbs, Kiyoshi W. Masui, Daniele Michilli | Summary: The gravitational field of compact objects, such as primordial black holes, can create multiple images of background sources. For transients such as fast radio bursts (FRBs), these multiple images can be resolved in […]

Measuring quasi-normal mode amplitudes with misaligned binary black hole ringdowns

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Halston Lim, Gaurav Khanna, Scott A. Hughes, , | Summary: In recent work, we examined how different modes in the ringdown phase of a binary coalescence are excited as a function of the final plunge geometry. At least in the large mass ratio limit, we found […]

HD 83443c: A highly eccentric giant planet on a 22-year orbit

Kavli Affiliate: Avi Shporer | First 5 Authors: Adriana Errico, Robert A. Wittenmyer, Jonathan Horner, Zhexing Li, Gregory Mirek Brandt | Summary: We report the discovery of a highly eccentric long-period Jovian planet orbiting the hot-Jupiter host HD,83443. By combining radial velocity data from four instruments (AAT/UCLES, Keck/HIRES, HARPS, Minerva-Australis) spanning more than two decades, […]

Impact of calibration uncertainties on Hubble constant measurements from gravitational-wave sources

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Yiwen Huang, Hsin-Yu Chen, Carl-Johan Haster, Ling Sun, Salvatore Vitale | Summary: Gravitational-wave (GW) detections of electromagnetically bright compact binary coalescences can provide an independent measurement of the Hubble constant $H_0$. In order to obtain a measurement that could help arbitrating the existing tension on $H_0$, one […]
