The evolutionary pathways of disk galaxies with different sizes

Kavli Affiliate: Luis C. Ho | First 5 Authors: Hong-Chuan Ma, Min Du, Luis C. Ho, Ming-jie Sheng, Shihong Liao | Summary: From the IllustrisTNG-50 simulation, a sample of 836 central disk galaxies with tiny stellar halos is chosen to study the inherent evolution of galaxies driven by nature. These galaxies are classified as compact, […]

FEASTS Combined with Interferometry (I): Overall Properties of Diffuse HI and Implications for Gas Accretion in Nearby Galaxies

Kavli Affiliate: Ran Wang | First 5 Authors: Jing Wang, Xuchen Lin, Dong Yang, Lister Staveley-Smith, Fabian Walter | Summary: We present a statistical study of the properties of diffuse HI in ten nearby galaxies, comparing the HI detected by the single-dish telescope FAST (FEASTS program) and the interferometer VLA (THINGS program), respectively. The THINGS’ […]

FlowWalker: A Memory-efficient and High-performance GPU-based Dynamic Graph Random Walk Framework

Kavli Affiliate: Jing Wang | First 5 Authors: Junyi Mei, Shixuan Sun, Chao Li, Cheng Xu, Cheng Chen | Summary: Dynamic graph random walk (DGRW) emerges as a practical tool for capturing structural relations within a graph. Effectively executing DGRW on GPU presents certain challenges. First, existing sampling methods demand a pre-processing buffer, causing substantial […]

Geometric deformation and redshift structure caused by plane gravitational waves

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Chao-Jun Feng, , , | Summary: The curved spacetime induced by gravitational waves can give rise to visual effects such as geometric distortions and redshift structures in the observed image. By establishing a mapping from the object’s surface coordinates to the observer’s screen coordinates, we […]

Monitoring AGNs with H$β$ Asymmetry. IV. First Reverberation Mapping Results of 14 AGNs

Kavli Affiliate: Luis C. Ho | First 5 Authors: T. E. Zastrocky, Michael S. Brotherton, Pu Du, Jacob N. McLane, Kianna A. Olson | Summary: We report first-time reverberation mapping results for 14 AGNs from the ongoing Monitoring AGNs with H$beta$ Asymmetry campaign (MAHA). These results utilize optical spectra obtained with the Long Slit Spectrograph […]

Extracting Clean and Balanced Subset for Noisy Long-tailed Classification

Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, He Zhao, Zhen Li, Tongliang Liu, Dandan Guo | Summary: Real-world datasets usually are class-imbalanced and corrupted by label noise. To solve the joint issue of long-tailed distribution and label noise, most previous works usually aim to design a noise detector to distinguish the noisy […]

eDIG-CHANGES II: Project Design and Initial Results on NGC 3556

Kavli Affiliate: Jing Wang | First 5 Authors: Jiang-Tao Li, Li-Yuan Lu, Zhijie Qu, Robert A. Benjamin, Joel N. Bregman | Summary: The extraplanar diffuse ionized gas (eDIG) represents ionized gases traced by optical/UV lines beyond the stellar extent of galaxies. We herein introduce a novel multi-slit narrow-band spectroscopy method to conduct spatially resolved spectroscopy […]
