Ejection-accretion connection in NLS1 AGN 1H 1934-063

Kavli Affiliate: Erin Kara | First 5 Authors: Yerong Xu, Ciro Pinto, Erin Kara, Megan Masterson, Javier A. García | Summary: Accretion and ejection of matter in active galactic nuclei (AGN) are tightly connected phenomena and represent fundamental mechanisms regulating the growth of the central supermassive black hole and the evolution of the host galaxy. […]

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 […]

ALMA/ACA CO Survey of the IC 1459 and NGC 4636 Groups: Environmental Effects on the Molecular Gas of Group Galaxies

Kavli Affiliate: Jing Wang | First 5 Authors: Bumhyun Lee, Jing Wang, Aeree Chung, Luis C. Ho, Ran Wang | Summary: We present new results of a 12CO(J=1-0) imaging survey using the Atacama Compact Array (ACA) for 31 HI detected galaxies in the IC 1459 and NGC 4636 groups. This is the first CO imaging […]

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, Honggeun 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 […]
