Predictions of Dust Continuum Emission from a Potential Circumplanetary Disk: A Case Study of the Planet Candidate AB Aurigae b

Kavli Affiliate: Ruobing Dong | First 5 Authors: Yuhito Shibaike, Jun Hashimoto, Ruobing Dong, Christoph Mordasini, Misato Fukagawa | Summary: Gas accreting planets embedded in protoplanetary disks are expected to show dust thermal emission from their circumplanetary disks (CPDs). However, a recently reported gas accreting planet candidate, AB Aurigae b, has not been detected in […]

Weakness of X-rays and Variability in High-redshift AGNs with Super-Eddington Accretion

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Inayoshi, Shigeo Kimura, Hirofumi Noda, , | Summary: The James Webb Space Telescope (JWST) observations enable the exploration of active galactic nuclei (AGNs) with broad-line emission in the early universe. Despite their clear radiative and morphological signatures of AGNs in rest-frame optical bands, complementary evidence of […]

A High Incidence of Central Star Formation Inferred from the Color Gradients of Galaxies at $z>4$

Kavli Affiliate: Luis C. Ho | First 5 Authors: Bingcheng Jin, Luis C. Ho, Wen Sun, , | Summary: We study the rest-frame ultraviolet-optical color gradients of 669 galaxies at $4<z<8$ by characterizing the wavelength dependence of their structural parameters derived from simultaneously fitting the seven-band NIRCam images acquired with the James Webb Space Telescope. […]

An Image Simulator of Lunar Far-Side Impact Flashes Captured from the Earth-Moon L2 Point

Kavli Affiliate: Jing Wang | First 5 Authors: Da Song, Hong-bo Cai, Shen Wang, Jing Wang, | Summary: Impact flashes on the moon are caused by high-speed collisions of celestial bodies with the lunar surface. The study of the impacts is critical for exploring the evolutionary history and formation of the Moon, and for quantifying […]

Formation Rate of Quasi-periodic Eruptions in Galactic Nuclei Containing Single and Dual Supermassive Black Holes

Kavli Affiliate: Xian Chen | First 5 Authors: Chunyang Cao, F. K. Liu, Xian Chen, Shuo Li, | Summary: Quasi-periodic eruptions (QPEs) are a novel class of transients recently discovered in a few extragalactic nuclei. It has been suggested that a QPE can be produced by a main-sequence star undergoing repeated partial disruptions by the […]

Rapid Rotation of Polarization Orientations in PSR B1919+21’s Single Pulses: Implications On Pulsar’s Magnetospheric Dynamics

Kavli Affiliate: Kejia Lee | First 5 Authors: Shunshun Cao, Jinchen Jiang, Jaroslaw Dyks, Kejia Lee, Jiguang Lu | Summary: We analyse and model rapid rotations of polarization orientations in PSR B1919+21’s single pulses, based on FAST observation data. In more than one third of B1919+21’s single pulses, polarization angle (PA) is found to rotate […]
