Exploring the origin of cold gas and star formation in a rare population of strongly bulge-dominated early-type Galaxies

Kavli Affiliate: Yingjie Peng | First 5 Authors: Fujia Li, Enci Wang, Ming Zhu, Yingjie Peng, Jing Wang | Summary: We analyze the properties of a rare population, the strongly bulge-dominated early-type galaxies (referred to as sBDEs) with significant HI gas, using the databases from the FAST All Sky HI survey (FASHI) and the Arecibo […]

The RAdio Galaxy Environment Reference Survey (RAGERS): Evidence of an anisotropic distribution of submillimeter galaxies in the 4C 23.56 protocluster at z=2.48

Kavli Affiliate: Ran Wang | First 5 Authors: Dazhi Zhou, Thomas R. Greve, Bitten Gullberg, Minju M. Lee, Luca Di Mascolo | Summary: High-redshift radio(-loud) galaxies (H$z$RGs) are massive galaxies with powerful radio-loud active galactic nuclei (AGNs) and serve as beacons for protocluster identification. However, the interplay between H$z$RGs and the large-scale environment remains unclear. […]

The most distant HI galaxies discovered by the 500 m dish FAST

Kavli Affiliate: Jing Wang | First 5 Authors: Hongwei Xi, Bo Peng, Lister Staveley-Smith, Bi-Qing For, Bin Liu | Summary: Neutral hydrogen (HI) is the primary component of the cool interstellar medium (ISM) and is the reservoir of fuel for star formation. Owing to the sensitivity of existing radio telescopes, our understanding of the evolution […]

Revisiting the fundamental metallicity relation with observation and simulation

Kavli Affiliate: Yingjie Peng | First 5 Authors: Chengyu Ma, Kai Wang, Enci Wang, Yingjie Peng, Haochen Jiang | Summary: The gas-phase metallicity of galaxies is regulated by multiple astrophysical processes, which makes it a crucial diagnostic of galaxy formation and evolution. Beyond the fundamental mass-metallicity relation, a debate about the secondary galaxy property to […]

Implementing Streaming algorithm and k-means clusters to RAG

Kavli Affiliate: Ke Wang | First 5 Authors: Haoyu Kang, Yuzhou Zhu, Yukun Zhong, Ke Wang, | Summary: Retrieval-augmented generation (RAG) has achieved great success in information retrieval to assist large models because it builds an external knowledge database. However, it also has many problems: it consumes a lot of memory because of the huge […]
