Improved Halo Model Calibrations for Mixed Dark Matter Models of Ultralight Axions

Kavli Affiliate: George Efstathiou | First 5 Authors: Tibor Dome, Simon May, Alex Laguë, David J. E. Marsh, Sarah Johnston | Summary: We study the implications of relaxing the requirement for ultralight axions to account for all dark matter in the Universe by examining mixed dark matter (MDM) cosmologies with axion fractions $f leq 0.3$ […]

Machine-learning convergent melanocytic morphology despite noisy archival slides

Kavli Affiliate: Michael Keiser | Authors: Mikio Tada, Garrett Gaskins, Sina Ghandian, Nicholas Mew, Michael J. Keiser and Elizabeth S. Keiser | Summary: Melanocytic atypia, ranging from benign to malignant, often leads to diagnostic discordance, complicating its prediction by machine learning models. To overcome this, we paired H&E-stained histology images with contiguous or serial sections […]

Thermo-mechanical Properties of Hierarchical Biocomposite Materials from Photosynthetic Microorganisms

Kavli Affiliate: Chiara Daraio | First 5 Authors: Israel Kellersztein, Daniel Tish, John Pederson, Martin Bechthold, Chiara Daraio | Summary: Extrusion 3D-printing of biopolymers and natural fiber-based biocomposites allows for the fabrication of complex structures, ranging from gels for healthcare applications to eco-friendly structural materials. However, traditional polymer extrusion demands high-energy consumption to pre-heat the […]

Gravitational waves from primordial black hole isocurvature: the effect of non-Gaussianities

Kavli Affiliate: Misao Sasaki | First 5 Authors: Xin-Chen He, Yi-Fu Cai, Xiao-Han Ma, Theodoros Papanikolaou, Emmanuel N. Saridakis | Summary: Ultra-light primordial black holes (PBHs) with masses $M_{rm PBH}<5times 10^8mathrm{g}$ can dominate transiently the energy budget of the Universe and reheat the Universe through their evaporation taking place before Big Bang Nucleosynthesis. The isocurvature […]

Vetting quark-star models with gravitational waves in the hierarchical Bayesian framework

Kavli Affiliate: Lijing Shao | First 5 Authors: Ziming Wang, Yong Gao, Dicong Liang, Junjie Zhao, Lijing Shao | Summary: The recent discovery of gravitational waves (GWs) has opened a new avenue for investigating the equation of state (EOS) of dense matter in compact stars, which is an outstanding problem in astronomy and nuclear physics. […]

Topological K-theory of quasi-BPS categories for Higgs bundles

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: In a previous paper, we introduced quasi-BPS categories for moduli stacks of semistable Higgs bundles. Under a certain condition on the rank, Euler characteristic, and weight, the quasi-BPS categories (called BPS in this case) are non-commutative analogues of Hitchin […]

Deciphering spatially resolved Lyman-alpha profiles in reionization analogs: the Sunburst Arc at cosmic noon

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Erik Solhaug, Hsiao-Wen Chen, Mandy C. Chen, Fakhri Zahedy, Max Gronke | Summary: The hydrogen Lyman-alpha (Lya) emission line, the brightest spectral feature of a photoionized gas, is considered an indirect tracer of the escape of Lyman continuum (LyC) photons, particularly when the intergalactic medium is […]
