A Machine-Learning Compositional Study of Exoplanetary Material Accreted Onto Five Helium-Atmosphere White Dwarfs with $texttt{cecilia}$

Posted by dbos May 9, 2025May 19, 2025MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Mariona Badenas-Agusti, Siyi Xu, Andrew Vanderburg, Kishalay De, Patrick Dufour | Summary: We present the first application of the Machine Learning (ML) pipeline $texttt{cecilia}$ to determine the physical parameters and photospheric composition of five metal-polluted He-atmosphere white dwarfs without well-characterised elemental abundances. To achieve this, we perform […]

Compilation strategies for quantum network programs using Qoala

Posted by dbos May 9, 2025May 19, 2025Delft

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Samuel Oslovich, Bart van der Vecht, Stephanie Wehner, , | Summary: Execution of quantum network applications requires a software stack for nodes. Recently, the first designs and demonstrations have been proposed for such software stacks, including QNodeOS and its extension, Qoala. The latter enables compilation strategies previously […]

Periodic variation of magnetoionic environment of a fast radio burst source

Posted by dbos May 9, 2025Peking

Kavli Affiliate: Kejia Lee | First 5 Authors: Jiangwei Xu, Heng Xu, Yanjun Guo, Jinchen Jiang, Bojun Wang | Summary: Fast radio bursts (FRBs) are luminous, dispersed millisecond-duration radio bursts whose origin is poorly known. Recent observations suggest that some FRBs may reside in binary systems, even though conclusive evidence remains elusive. Here we report […]

Scattering Entanglement Entropy and Its Implications for Electroweak Phase Transitions

Posted by dbos May 9, 2025Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Jia Liu, Masanori Tanaka, Xiao-Ping Wang, Jing-Jun Zhang, Zifan Zheng | Summary: We investigate the connection between the entanglement entropy in scattering processes and the dynamics of electroweak phase transitions. Recent work has shown that the scattering entanglement entropy can provide new insight into Standard Model parameters. […]

Inferring charge noise source locations from correlations in spin qubits

Posted by dbos May 9, 2025Delft

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Juan S. Rojas-Arias, Akito Noiri, Jun Yoneda, Peter Stano, Takashi Nakajima | Summary: We investigate low-frequency noise in a spin-qubit device made in isotopically purified Si/Si-Ge. Observing sizable cross-correlations among energy fluctuations of different qubits, we conclude that these fluctuations are dominated by charge noise. At low […]

The AGORA High-Resolution Galaxy Simulations Comparison Project VII: Satellite quenching in zoom-in simulation of a Milky Way-mass halo

Posted by dbos May 9, 2025Stanford

Kavli Affiliate: Tom Abel | First 5 Authors: R. Rodríguez-Cardoso, S. Roca-Fàbrega, Minyong Jung, Thinh H. Nguyen, Ji-hoon Kim | Summary: Context: Satellite galaxies experience multiple physical processes when interacting with their host halos, often leading to the quenching of star formation. In the Local Group (LG), satellite quenching has been shown to be highly […]

The {it AGORA} High-resolution Galaxy Simulations Comparison Project. VIII: Disk Formation and Evolution of Simulated Milky Way Mass Galaxy Progenitors at $1<z<5$

Posted by dbos May 9, 2025Stanford

Kavli Affiliate: Tom Abel | First 5 Authors: Minyong Jung, Ji-hoon Kim, Thinh H. Nguyen, Ramon Rodriguez-Cardoso, Santi Roca-Fàbrega | Summary: We investigate how differences in the stellar feedback produce disks with different morphologies in Milky Way-like progenitors over 1 $leq z leq 5$, using eight state-of-the-art cosmological hydrodynamics simulation codes in the textit{AGORA} project.
