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 […]

Prediction-Assisted Online Distributed Deep Learning Workload Scheduling in GPU Clusters

Kavli Affiliate: Jia Liu | First 5 Authors: Ziyue Luo, Jia Liu, Myungjin Lee, Ness B. Shroff, | Summary: The recent explosive growth of deep learning (DL) models has necessitated a compelling need for efficient job scheduling for distributed deep learning training with mixed parallelisms (DDLwMP) in GPU clusters. This paper proposes an adaptive shortest-remaining-processing-time-first […]

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 […]

Crystals and Double Quiver Algebras from Jeffrey-Kirwan Residues

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Jiakang Bao, Masahito Yamazaki, , , | Summary: We construct statistical mechanical models of crystal melting describing the flavoured Witten indices of $mathcal{N}ge 2$ supersymmetric quiver gauge theories. Our results can be derived from the Jeffrey-Kirwan (JK) residue formulas, and generalize the previous results for quivers corresponding […]

Clumps as multiscale structures in cosmic noon galaxies

Kavli Affiliate: John D. Silverman | First 5 Authors: Boris S Kalita, Tomoko L Suzuki, Daichi Kashino, John D Silverman, Emanuele Daddi | Summary: Star-forming clumps have been found to significantly influence the star formation of gas-rich $z>1$ galaxies. Using public data from JWST/NIRCam (COSMOS-Web) and ALMA (FMOS-COSMOS), we study a sample of 32 massive […]

A multi-wavelength investigation of spiral structures in $z > 1$ galaxies with JWST

Kavli Affiliate: John D. Silverman | First 5 Authors: Boris S. Kalita, Si-Yue Yu, John D. Silverman, Emanuele Daddi, Luis C. Ho | Summary: Recent JWST observations have revealed the prevalence of spiral structures at $z > 1$. Unlike in the local Universe, the origin and the consequence of spirals at this epoch remain unexplored. […]

Primordial Black Hole Formation from Power Spectrum with Finite-width

Kavli Affiliate: Misao Sasaki | First 5 Authors: Shi Pi, Misao Sasaki, Volodymyr Takhistov, Jianing Wang, | Summary: Primordial Black Holes (PBHs) can form from gravitational collapse of large overdensities in the early Universe, giving rise to rich phenomena in astrophysics and cosmology. We develop a novel, general, and accurate method based on theory of […]
