Kavli Affiliate: Kerry Vahala | First 5 Authors: Zhiquan Yuan, Jinhao Ge, Peng Liu, Bohan Li, Mingxiao Li | Summary: Achieving compact and efficient visible laser sources is crucial for a wide range of applications. However traditional semiconductor laser technology faces difficulties in producing high-brightness green light, leaving a green gap in wavelength coverage. Second-harmonic […]
Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Aurora Ireland, Tong Ou, Isaac R. Wang, | Summary: A precise determination of the bubble wall velocity $v_w$ is crucial for making accurate predictions of the baryon asymmetry and gravitational wave (GW) signals in models of electroweak baryogenesis (EWBG). Working in the local thermal equilibrium […]
Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Gareth Arturo Marks, Seppe J. Staelens, Tamara Evstafyeva, Ulrich Sperhake, | Summary: We study the stability of ultracompact boson stars admitting light rings combining a perturbative analysis with 3+1 numerical-relativity simulations with and without symmetry assumptions. We observe excellent agreement between all perturbative and numerical results which […]
Kavli Affiliate: T. Higuchi | First 5 Authors: K. Ravindran, K. Adamczyk, H. Aihara, S. Bacher, S. Bahinipati | Summary: In 2024, the Belle II experiment resumed data taking after the Long Shutdown 1, which was required to install a two-layer pixel detector and upgrade accelerator components. We describe the challenges of this shutdown and […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Stephanie Buttigieg, Debora Sijacki, Christopher J. Moore, Martin A. Bourne, | Summary: The co-evolution of massive black holes (BHs) and their host galaxies is well-established within the hierarchical galaxy formation paradigm. Large-scale cosmological simulations are an ideal tool to study the repeated BH mergers, accretion and feedback […]

Kavli Affiliate: Scott Small | Authors: Clara T Rehmann, Scott T Small, Peter L Ralph and Andrew D. Kern | Summary: As organisms adapt to environmental changes, natural selection modifies the frequency of non-neutral alleles. For beneficial mutations, the outcome of this process may be a selective sweep, in which an allele rapidly increases in […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Christa DeCoursey, Christa DeCoursey, , , | Summary: The James Webb Space Telescope (JWST) discovered 79 transients out to $z$$sim$4.8 through the JADES Transient Survey (JTS), but the JTS did not find any $z$$>$5 transients. Here, we present the first photometric evidence of a $z$$>$5 transient/variable source […]
