The PSF Smoothing Effect on Concentration-Related Parameters of High Redshift Galaxies in HST and JWST

Kavli Affiliate: Luis C. Ho | First 5 Authors: Jia-Hui Wang, Zhao-Yu Li, Ming-Yang Zhuang, Luis C. Ho, Li-Min Lai | Summary: We perform a comprehensive investigation of the PSF smoothing effect on the measurement of concentration-related parameters ($C$, Gini, $M_{20}$) of high redshift galaxies in the HST and JWST surveys. Our sample contains massive […]

Global self$-$similarity of dense granular flow in hopper: the role of hopper width

Kavli Affiliate: Li Xin Li | First 5 Authors: Changhao Li, Xin Li, Xianggui Chen, Zaixin Wang, Min Sun | Summary: The influence of hopper width on the dense granular flow in a two-dimensional hopper is investigated by experiments and simulations. The flow rate remains constant for larger hopper width, while a slight decrease of […]

A Search for Temporal Atmospheric Variability of $textit{Kepler}$ Hot Jupiters

Kavli Affiliate: Avi Shporer | First 5 Authors: Canis Li, Avi Shporer, , , | Summary: We perform a systematic search for atmospheric variability in short-period gas-giant planets (hot Jupiters) observed by the Kepler mission, by looking for temporal variability of their secondary eclipse depths. This is motivated by a recent detection of a decrease […]

Signatures of tidal disruption of the Hercules ultra-faint dwarf galaxy

Kavli Affiliate: Anna Frebel | First 5 Authors: Xiaowei Ou, Anirudh Chiti, Nora Shipp, Joshua D. Simon, Marla Geha | Summary: The Hercules ultra-faint dwarf galaxy (UFD) has long been hypothesized to be tidally disrupting, yet no conclusive evidence has been found for tidal disruption owing partly to difficulties in identifying Hercules member stars. In […]
