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 […]

Inferring Maps of the Sun’s Far-side Unsigned Magnetic Flux from Far-side Helioseismic Images using Machine Learning Techniques

Kavli Affiliate: J. Todd Hoeksema | First 5 Authors: Ruizhu Chen, Junwei Zhao, Shea Hess Webber, Yang Liu, J. Todd Hoeksema | Summary: Accurate modeling of the Sun’s coronal magnetic field and solar wind structures require inputs of the solar global magnetic field, including both the near and far sides, but the Sun’s far-side magnetic […]

The categorical DT/PT correspondence and quasi-BPS categories for local surfaces

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: We construct semiorthogonal decompositions of Donaldson-Thomas (DT) categories for reduced curve classes on local surfaces into products of quasi-BPS categories and Pandharipande-Thomas (PT) categories, giving a categorical analogue of the numerical DT/PT correspondence for Calabi-Yau 3-folds. The main ingredient […]
