Clumpy Starburst in a Local Dwarf Galaxy, NGC 1522
Liuze Long, Yulong Gao, Qiusheng Gu +8
To investigate the star-forming process in nearby dwarf galaxies, we present Integral Field Units (IFU) observation of the star-forming dwarf galaxy, NGC 1522, with the Very Large…
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…
From Halos to Galaxies. X: Decoding Galaxy SEDs with Physical Priors and Accurate Star Formation History Reconstruction
Zeyu Gao, Yingjie Peng, Kai Wang +18
The spectral energy distribution (SED) of galaxies is essential for deriving fundamental properties like stellar mass and star formation history (SFH). However, conventional method…
From Halos to Galaxies. VI. Improved halo mass estimation for SDSS groups and measurement of the halo mass function
Dingyi Zhao, Yingjie Peng, Yipeng Jing +18
In CDM cosmology, galaxies form and evolve in their host dark matter (DM) halos. Halo mass is crucial for understanding the halo-galaxy connection. The abundance matching (AM)…
