Reconstructing the Projected Dark Matter Field across 0.1-100 Mpc Scales from the SDSS Survey

Kunyao Zhao, Yingjie Peng, Dingyi Zhao +16

Dark matter sets the gravitational environment in which galaxies form and evolve, but cannot be observed directly. We present a conditional diffusion model that reconstructs the pr…

No Detectable One-halo Galactic Conformity Signal with Halo-mass Estimates Consistent with Weak-lensing Constraints

Dingyi Zhao, Yingjie Peng, Luis C. Ho +17

One-halo galactic conformity is the tendency for satellites in halos with quenched centrals to have lower star-formation activity than those in halos with star-forming centrals at…

Bar-driven secular evolution largely complete in a disk galaxy 7.6 billion years ago

Takafumi Tsukui, Zeyu Gao, Emily Wisnioski +4

Disk galaxies like the Milky Way are thought to evolve through internal dynamical processes: the stellar disk forms a bar, the bar drives gas inflow that builds a nuclear stellar d…

Formation and Environmental Context of Giant Bulgeless Disk Galaxies in the Early Universe: Insights from Cosmological Simulations

Fangzhou Jiang, Jinning Liang, Bingcheng Jin +7

Giant bulgeless disk galaxies, theoretically expected to be rare in the early Universe, have been confirmed by the James Webb Space Telescope (JWST) to exist as early as 2 billion…

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…

Abundant Molecular Gas in the Central Region of Lenticular Galaxy PGC 39535

Jiantong Cui, Qiusheng Gu, Shiying Lu +3

Lenticular galaxies (S0s) in the local universe are generally absent of recent star formation and lack molecular gas. In this paper, we investigate one massive (5$\times…

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) t…

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…
