Wasserstein distance between noncommutative dynamical systems
Rocco Duvenhage
We study a class of quadratic Wasserstein distances on spaces consisting of generalized dynamical systems on a von Neumann algebra. We emphasize how symmetry of such a Wasserstein…
Explicit solutions to some fragmentation equations with growth or decay
Jacek Banasiak, David Wetsi Poka, Sergey Shindin
In this paper, we provide a systematic way of finding explicit solutions for a class of continuous fragmentation equations with growth or decay in the state space and derive explic…
HI in and behind the Hubble Frontier Field Clusters: A Deep MeerKAT Pilot Search out to
Shilpa Ranchod, Roger Deane, Danail Obreschkow +2
The Hubble Frontier Fields (HFF) are a selection of well-studied galaxy clusters used to probe dense environments and distant gravitationally lensed galaxies. We explore the 21cm n…
Training Cross-Lingual embeddings for Setswana and Sepedi
Mack Makgatho, Vukosi Marivate, Tshephisho Sefara +1
African languages still lag in the advances of Natural Language Processing techniques, one reason being the lack of representative data, having a technique that can transfer inform…
The MeerKAT Galaxy Cluster Legacy Survey I. Survey Overview and Highlights
K. Knowles, W. D. Cotton, L. Rudnick +148
MeerKAT's large number of antennas, spanning 8 km with a densely packed 1 km core, create a powerful instrument for wide-area surveys, with high sensitivity over a wide range of an…
Event Horizon Telescope observations of the jet launching and collimation in Centaurus A
Michael Janssen, Heino Falcke, Matthias Kadler +236
Very-long-baseline interferometry (VLBI) observations of active galactic nuclei at millimeter wavelengths have the power to reveal the launching and initial collimation region of e…
