Investigating the vertical distribution of the disk as a function of radial action: Results from simulations
Yunpeng Jia, Chengqun Yang, Yuqin Chen +2
Previous research has established a relationship between radial action and scale height in Galactic disks, unveiling a correlation between radial and vertical heating. This finding…
Unveiling the Binary Nature of NGC 2323
Songmei Qin, Jing Zhong, Tong Tang +9
As a well-known open cluster, NGC 2323 (also called M50) has been widely investigated for over a hundred years and has always been considered a classical single cluster. In this wo…
A resolved Lyman-Alpha profile with doubly peaked emission at z~7
C. Moya-Sierralta, J. González-López, L. Infante +7
The epoch of reionization is a landmark in structure formation and galaxy evolution. How it happened is still not clear, especially regarding which population of objects was respon…
The HI Mass Function of the Local Universe: Combining Measurements from HIPASS, ALFALFA and FASHI
Wenlin Ma, Hong Guo, Haojie Xu +6
We present the first HI mass function (HIMF) measurement for the recent FAST All Sky HI (FASHI) survey and the most complete measurements of HIMF in the local universe thus far. We…
Equilibrium dynamical models in the inner region of the Large Magellanic Cloud based on Gaia DR3 kinematics
Nikolay Kacharov, Behzad Tahmasebzadeh, Maria-Rosa L. Cioni +3
We use Gaia DR3 to explore how well equilibrium dynamical models based on the Jeans equations and the Schwarzschild orbit superposition method are able to describe LMC's 5-dimensio…
Capivara: A Spectral-based Segmentation Method for IFU Data Cubes
Rafael S. de Souza, Luis G. Dahmer-Hahn, Shiyin Shen +7
We present capivara, a fast and scalable spectral-based segmentation package designed to study astrophysical properties within distinct structural components of galaxies. This spec…
The warm-hot intergalactic medium in inter-cluster filaments -- A forecast for HUBS observations based on eRASS1 superclusters
Yuanyuan Zhao, Haiguang Xu, Ang Liu +8
Cosmological simulations indicate that nearly half of the baryons in the nearby Universe are in the warm-hot intergalactic medium (WHIM) phase, and about a half them reside in cosm…
