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: Kohei Inayoshi | First 5 Authors: Christa DeCoursey, Eiichi Egami, Fengwu Sun, Arshia Akhtarkavan, Rachana Bhatawdekar | 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 […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Ronny Frumkin, Yonit Hochberg, Eric Kuflik, Hitoshi Murayama, | Summary: Inverse decays are an interesting avenue for producing dark matter in the early universe. We study in detail various phases of dark matter parameter space where inverse decays control its abundance, expanding on our work of INDY […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Mary Anne Limbach, Andrew Vanderburg, Ryan J. MacDonald, Kevin B. Stevenson, Sydney Jenkins | Summary: We report the detection of thermal emission from and confirm the planetary nature of WD 1856+534b, the first transiting planet known to orbit a white dwarf star. Observations with JWST’s Mid-Infrared Instrument […]
