Long-term stable nonlinear evolutions of ultracompact black-hole mimickers

Posted by dbos Cambridge

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 […]

Operational experience and performance of the Silicon Vertex Detector after the first long shutdown of Belle II

Posted by dbos Tokyo

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 […]

Premature supermassive black hole mergers in cosmological simulations of structure formation

Posted by dbos Cambridge

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 […]

Sweeps in space: leveraging geographic data to identify beneficial alleles in Anopheles gambiae

Posted by dbos Columbia

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 […]

The First Photometric Evidence of a Transient/Variable Source at z>5 with JWST

Posted by dbos Peking

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 […]

Posted by dbos MIT

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 […]

Phases of Dark Matter from Inverse Decays

Posted by dbos Tokyo

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 […]

Practical approaches for crystal structure predictions with inpainting generation and universal interatomic potentials

Posted by dbos Berkeley

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Peichen Zhong, Xinzhe Dai, Bowen Deng, Gerbrand Ceder, Kristin A. Persson | Summary: We present Crystal Host-Guided Generation (CHGGen), a diffusion-based framework for crystal structure prediction. Unconditional generation with diffusion models demonstrates limited efficacy in identifying symmetric crystals as the unit cell size increases. CHGGen addresses […]
