Cosmological inference from the emulator based halo model II: Joint analysis of galaxy-galaxy weak lensing and galaxy clustering from HSC-Y1 and SDSS

Kavli Affiliate: Chiaki Hikage | Summary:We present high-fidelity cosmology results from a blinded joint analysis of galaxy-galaxy weak lensing ($Δ!Σ$) and projected galaxy clustering ($w_rm p$) measured from the Hyper Suprime-Cam Year-1 (HSC-Y1) data and spectroscopic Sloan Digital Sky Survey (SDSS) galaxy catalogs in the redshift range $0.15<z<0.7$. We define luminosity-limited samples of SDSS galaxies […]

Hyperbolic Embeddings in Toric Geometry: Effectivity and Deformation Stability

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:We study the deformation behavior of Kobayashi hyperbolic embeddings for complements of divisors in projective toric varieties. In the toric setting, entire curves in divisor complements propagate along algebraic subtori, allowing hyperbolicity questions to be translated into combinatorial conditions on lattice-point configurations […]

Direct Computation of Monodromy Matrices and Classification of 4d N=2 Heterotic–IIA Dual Vacua

Kavli Affiliate: Taizan Watari | Summary:We compute the monodromy matrices on the special geometry of 4d N=2 Heterotic–IIA dual vacua in some simple cases by numerical evaluation of the period integrals, without assuming geometric background. The integrality of the monodromy matrices constrains some classification invariants of the string vacua. We also mention some mathematical open […]

The Variability of the Black-Hole Image in M87 at the Dynamical Time Scale

Kavli Affiliate: John E. Carlstrom | First 5 Authors: Kaushik Satapathy, Dimitrios Psaltis, Feryal Ozel, Lia Medeiros, Sean T. Dougall | Summary: The black-hole images obtained with the Event Horizon Telescope (EHT) are expected to be variable at the dynamical timescale near their horizons. For the black hole at the center of the M87 galaxy, […]
