Supernova-driven turbulent metal mixing in high redshift galactic disks: metallicity fluctuations in the interstellar medium and its imprints on metal poor stars in the Milky Way

Posted by klaurent Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Anne Noer Kolborg, Davide Martizzi, Enrico Ramirez-Ruiz, Hugo Pfister, Charli Sakari | Summary: The extent to which turbulence mixes gas in the face of recurrent infusions of fresh metals by supernovae (SNe) could help provide important constraints on the local star formation conditions. This includes predictions […]

VLA Radio Study of a Sample of Nearby X-ray and Optically Bright Early-Type Galaxies

Posted by klaurent Stanford

Kavli Affiliate: Steven W. Allen | First 5 Authors: Romana Grossová, Norbert Werner, Francesco Massaro, Kiran Lakhchaura, Tomáš Plšek | Summary: Many massive early-type galaxies host central radio sources and hot X-ray atmospheres indicating the presence of radio-mechanical active galactic nucleus (AGN) feedback. The duty cycle and detailed physics of the radio-mode AGN feedback is […]

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

Posted by klaurent Tokyo

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

Posted by klaurent Stanford

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

Posted by klaurent Tokyo

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 […]
