Kavli Affiliate: Lile Wang | First 5 Authors: Xiaoyu Zhang, Yuxiao Yi, Lile Wang, Zhi-Qin John Xu, Tianhan Zhang | Summary: In astrophysical simulations, nuclear reacting flows pose computational challenges due to the stiffness of reaction networks. We introduce neural network-based surrogate models using the DeePODE framework to enhance simulation efficiency while maintaining accuracy and […]
Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Sijia Ke, Stephen E. Gant, Leeor Kronik, Jeffrey B. Neaton, | Summary: We use density functional theory (DFT) with non-empirically tuned screened range-separated hybrid (SRSH) functionals to calculate the electronic properties of native zinc and oxygen vacancy point defects in ZnO, and we predict their defect […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Zihao Wu, Luis C. Ho, , , | Summary: Recent studies suggest that numerous intermediate-mass black holes (IMBHs) may wander undetected across the Universe, emitting little radiation. These IMBHs largely preserve their birth masses, offering critical insights into the formation of heavy black hole seeds and […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Kai Murai, Fuminobu Takahashi, , | Summary: We study the evolution of Q-balls under a spontaneously broken global $U(1)$ symmetry. Q-balls are stabilized by the conservation of $U(1)$ charge, but when the symmetry is spontaneously broken, the resulting Nambu-Goldstone (NG) boson can carry charge away […]

Korfhage, Rolando Garcia-Milian, Katerina D Melnyk, Joerg Bewersdorf, Pietro De Camilli and Thomas Melia | Summary: Autophagosomes form from seed membranes that expand through bulk-lipid transport via the bridge-like lipid transporter ATG2. The origins of […]

Kavli Affiliate: Rui Costa | Authors: Dabal Pedamonti, Samia Mohinta, Martin Dimitrov, Hugo Malagon-Vina, Stephane Ciocchi and Rui Ponte Costa | Summary: Mastering navigation in environments with limited visibility is crucial for survival. Although the hippocam-pus has been associated with goal-oriented navigation, its role in real-world behaviour remains unclear. To investigate this, we combined deep […]
Kavli Affiliate: Vahe Petrosian | First 5 Authors: Sujay Champati, Vahé Petrosian, , , | Summary: We investigate the cosmological evolution of the luminosity and redshift of FRBs. As is the case for all extragalactic sources, we are dealing with data that are truncated by observational selection effects, the most important being the flux limit, […]
Kavli Affiliate: Abigail G. Vieregg | First 5 Authors: Andrew Zeolla, Jaime Alvarez-Muñiz, Sergio Cabana-Freire, Washington Carvalho Jr., Austin Cummings | Summary: Ultra-high energy neutrinos ($E>10^{17}$ eV) can provide insight into the most powerful accelerators in the universe, however their flux is extremely low. The Beamforming Elevated Array for COsmic Neutrinos (BEACON) is a detector […]
Kavli Affiliate: Anthony Lasenby | First 5 Authors: Yi-Hsiung Hsu, Will Barker, Michael Hobson, Anthony Lasenby, | Summary: We investigate the conditions under which a hypersurface becomes null through the use of coordinate transformations. We demonstrate that, in static spacetimes, the correct criterion for a surface to be null is~$g_{tt} = 0$, rather than~$g^{rr} = […]
