Ruffled Feathers: Merger-driven galaxy size growth and structural transformation in EAGLE
Kai Wang, Carlton Baugh, Sownak Bose +9
Galaxy mergers drive both the size growth and the transformation from discs to spheroids, yet the prescriptions used to model these processes in semi-analytic frameworks have not b…
Photometric Metallicities for 367,324 stars of Omega Centauri
Xue Lu, Haibo Yuan, Bowen Huang +2
Omega Centauri is the most massive and chemically complex multi-population globular cluster with a wide metallicity range that has been extensively studied photometrically and spec…
No [CII] or dust detection in two Little Red Dots at z > 7
Mengyuan Xiao, Pascal A. Oesch, Longji Bing +30
Little Red Dots (LRDs) are compact, point-like sources characterized by their red color and broad Balmer lines, which have been debated to be either dominated by active galactic nu…
The critical role of dark matter halos in driving star formation
Jing Dou, Yingjie Peng, Qiusheng Gu +13
Understanding the physical mechanisms that drive star formation is crucial for advancing our knowledge of galaxy evolution. We explore the interrelationships between key galaxy pro…
Peculiar velocities of galaxy clusters in a IllustrisTNG simulation based on mock observations of Sunyaev-Zel'dovich effects
Kaiyi Du, Yong Shi, Tao Wang +1
Galaxy clusters are the largest self-gravitational systems in the Universe. They are valuable probes of the structure growth of the Universe when we estimate their peculiar velocit…
