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 […]

Detection of stellar light from quasar host galaxies at redshifts above 6

Kavli Affiliate: John D. Silverman | First 5 Authors: Xuheng Ding, Masafusa Onoue, John D. Silverman, Yoshiki Matsuoka, Takuma Izumi | Summary: The detection of starlight from the host galaxies of quasars during the reionization epoch ($z>6$) has been elusive, even with deep HST observations. The current highest redshift quasar host detected, at $z=4.5$, required […]

The SPHERE view of three interacting twin disc systems in polarised light

Kavli Affiliate: David Principe | First 5 Authors: Philipp Weber, Sebastián Pérez, Greta Guidi, Nicolás T. Kurtovic, Alice Zurlo | Summary: Dense stellar environments as hosts of ongoing star formation increase the probability of gravitational encounters among stellar systems during the early stages of evolution. Stellar interaction may occur through non-recurring, hyperbolic or parabolic passages […]

Ganymede MHD Model: Magnetospheric Context for Juno’s PJ34 Flyby

Kavli Affiliate: George Clark | First 5 Authors: Stefan Duling, Joachim Saur, George Clark, Frederic Allegrini, Thomas Greathouse | Summary: On June 7th, 2021 the Juno spacecraft visited Ganymede and provided the first in situ observations since Galileo’s last flyby in 2000. The measurements obtained along a one-dimensional trajectory can be brought into global context […]

Logarithmic Duality of the Curvature Perturbation

Kavli Affiliate: Misao Sasaki | First 5 Authors: Shi Pi, Misao Sasaki, , , | Summary: We study the comoving curvature perturbation $mathcal{R}$ in the single-field inflation models whose potential can be approximated by a piecewise quadratic potential $V(varphi)$ by using the $delta N$ formalism. We find a general formula for $mathcal{R}(deltavarphi, deltapi)$, consisting of […]
