Kavli Affiliate: Herman L. Marshall | First 5 Authors: John Rankin, Fabio La Monaca, Alessandro Di Marco, Juri Poutanen, Anna Bobrikova | Summary: Cir X-1 is a neutron star X-ray binary characterized by strong variations in flux during its eccentric $sim$16.6 days orbit. There are also strong variations in the spectral state, and historically it […]
Kavli Affiliate: Jia Liu | First 5 Authors: Tianchen Zhou, Jia Liu, Yang Jiao, Chaosheng Dong, Yetian Chen | Summary: Online learning to rank (ONL2R) is a foundational problem for recommender systems and has received increasing attention in recent years. Among the existing approaches for ONL2R, a natural modeling architecture is the multi-armed bandit framework […]
Kavli Affiliate: Kent Irwin | Summary:The CMB-S4 experiment is developing next-generation ground-based microwave telescopes to observe the Cosmic Microwave Background with unprecedented sensitivity. This will require an order of magnitude increase in the 100 mK detector count, which in turn increases the demands on the readout system. The CMB-S4 readout will use time division multiplexing […]

Kavli Affiliate: Luis C. Ho | First 5 Authors: Xinyue Liang, Si-Yue Yu, Taotao Fang, Luis C. Ho, | Summary: Understanding the methodological robustness in identifying and quantifying high-redshift bars is essential for studying their evolution with the {it James} {it Webb} Space Telescope (JWST). We used nearby spiral galaxies to generate simulated images at […]

Using a sample of nearby spiral galaxies, we created simulated […]
Kavli Affiliate: Birgitta Whaley | First 5 Authors: Ho Nam Nguyen, Felix Motzoi, Mekena Metcalf, K. Birgitta Whaley, Marin Bukov | Summary: The utility of a quantum computer depends heavily on the ability to reliably perform accurate quantum logic operations. For finding optimal control solutions, it is of particular interest to explore model-free approaches, since […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Jeremy Heyl, Victor Doroshenko, Denis González-Caniulef, Ilaria Caiazzo, Juri Poutanen | Summary: In an accreting X-ray pulsar, a neutron star accretes matter from a stellar companion through an accretion disk. The high magnetic field of the rotating neutron star disrupts the inner edge of the disc, […]
Kavli Affiliate: Albert Stebbins | First 5 Authors: Juhun Kwak, John Podczerwinski, Peter Timbie, Réza Ansari, John Marriner | Summary: The visibilities measured by radio astronomical interferometers include non-astronomical correlated signals that arise from the local environment of the array. These correlated signals are especially important in compact arrays such as those under development for […]
