Three-dimensional core-collapse supernova models with phenomenological treatment of neutrino flavor conversions

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Kanji Mori, Tomoya Takiwaki, Kei Kotake, Shunsaku Horiuchi, | Summary: We perform three-dimensional supernova simulations with a phenomenological treatment of neutrino flavor conversions. We show that the explosion energy can increase to as high as ~10^51 erg depending on the critical density for the onset of flavor […]

On the equivalence between galaxy angular correlation function and power spectrum in constraining primordial non-Gaussianity

Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryo Terasawa, Yue Nan, Masahiro Takada, , | Summary: We investigate the angular power spectrum ($C_ell)$ and angular correlation function ($w(theta)$) of galaxy number density field in the presence of the local-type primordial non-Gaussianity (PNG), explicitly accounting for the integral constraint in an all-sky survey. We show […]

Global symmetries of quantum lattice models under non-invertible dualities

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Weiguang Cao, Yuan Miao, Masahito Yamazaki, , | Summary: Non-invertible dualities/symmetries have become an important tool in the study of quantum field theories and quantum lattice models in recent years. One of the most studied examples is non-invertible dualities obtained by gauging a discrete group. When the […]

Assessing the dark matter content of two quasar host galaxies at z~6 through gas kinematics

Kavli Affiliate: John D. Silverman | First 5 Authors: Qinyue Fei, John D. Silverman, Seiji Fujimoto, Ran Wang, Luis C. Ho | Summary: We conduct a study of the gas kinematics of two quasar host galaxies at $zgtrsim6$ traced by the [CII] emission line using ALMA. By combining deep observations at both low and high […]

The impact of the redshift-dependent selection effect of halos on the redshift-space power spectrum

Kavli Affiliate: Masahiro Takada | First 5 Authors: Kanmi Nose, Masahiro Takada, Ryo Terasawa, , | Summary: In a wide-area spectroscopic survey of galaxies, it is nearly impossible to obtain a homogeneous sample of galaxies with respect to galaxy properties such as stellar mass and host halo mass across a range of redshifts. Despite the […]

Dark matter from inflationary quantum fluctuations

Kavli Affiliate: Misao Sasaki | First 5 Authors: Mohammad Ali Gorji, Misao Sasaki, Teruaki Suyama, , | Summary: We explore a scenario in which dark matter is a massive bosonic field, arising solely from quantum fluctuations generated during inflation. In this framework, dark matter exhibits primordial isocurvature perturbations with an amplitude of ${cal O}(1)$ at […]
