Reconstruction of a surface from the category of reflexive sheaves

Kavli Affiliate: Alexey Bondal | First 5 Authors: Agnieszka Bodzenta, Alexey Bondal, , , | Summary: We define a normal surface $X$ to be codim-2-saturated if any open embedding of $X$ into a normal surface with the complement of codimension 2 is an isomorphism. We show that any normal surface $X$ allows a codim-2-saturated model […]

Searching for Ultralight Dark Matter Conversion in Solar Corona using Low Frequency Array Data

Kavli Affiliate: Jia Liu | First 5 Authors: Haipeng An, Xingyao Chen, Shuailiang Ge, Jia Liu, Yan Luo | Summary: Ultralight dark photons and axions are well-motivated hypothetical dark matter candidates. Both dark photon dark matter and axion dark matter can resonantly convert into electromagnetic waves in the solar corona when their mass is equal […]

The cosmic web of X-ray active galactic nuclei seen through the eROSITA Final Equatorial Depth Survey (eFEDS)

Kavli Affiliate: John Silverman | First 5 Authors: Johan Comparat, Wentao Luo, Andrea Merloni, Surhud More, Mara Salvato | Summary: Which galaxies in the general population turn into active galactic nuclei (AGNs) is a keystone of galaxy formation and evolution. Thanks to SRG/eROSITA’s contiguous 140 square degree pilot survey field, we constructed a large, complete, […]

Enhanced prospects for direct detection of inelastic dark matter from a non-galactic diffuse component

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Gonzalo Herrera, Alejandro Ibarra, Satoshi Shirai, , | Summary: In some scenarios, the dark matter particle predominantly scatters inelastically with the target, producing a heavier neutral particle in the final state. In this class of scenarios, the reach in parameter space of direct detection experiments is limited […]

Towards Hodge Theoretic Characterizations of 2d Rational SCFTs: II

Kavli Affiliate: Taizan Watari | First 5 Authors: Masaki Okada, Taizan Watari, , , | Summary: A characterization of rational superconformal field theories (SCFTs) on 1+1 dimensions with Ricci-flat Kahler targets was proposed by S. Gukov and C. Vafa in terms of the Hodge structure of the target space. The article [arXiv:2205.10299] refined this idea […]

A General Framework for Removing Point Spread Function Additive Systematics in Cosmological Weak Lensing Analysis

Kavli Affiliate: Masahiro Takada | First 5 Authors: Tianqing Zhang, Xiangchong Li, Roohi Dalal, Rachel Mandelbaum, Michael A. Strauss | Summary: Cosmological weak lensing measurements rely on a precise measurement of the shear two-point correlation function (2PCF) along with a deep understanding of systematics that affect it. In this work, we demonstrate a general framework […]

Search for an invisible $Z^prime$ in a final state with two muons and missing energy at Belle II

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, K. Adamczyk, L. Aggarwal, H. Ahmed | Summary: The $L_{mu}-L_{tau}$ extension of the standard model predicts the existence of a lepton-flavor-universality-violating $Z^{prime}$ boson that couples only to the heavier lepton families. We search for such a $Z^prime$ through its invisible decay in […]

Weak Lensing Tomographic Redshift Distribution Inference for the Hyper Suprime-Cam Subaru Strategic Program three-year shape catalogue

Kavli Affiliate: Masahiro Takada | First 5 Authors: Markus Michael Rau, Roohi Dalal, Tianqing Zhang, Xiangchong Li, Atsushi J. Nishizawa | Summary: We present posterior sample redshift distributions for the Hyper Suprime-Cam Subaru Strategic Program Weak Lensing three-year (HSC Y3) analysis. Using the galaxies’ photometry and spatial cross-correlations, we conduct a combined Bayesian Hierarchical Inference […]
