Detection of HI filament: Pair Stacking vs. Filament Stacking
Yuxi Meng, Jie Wang, Yingjie Jing +2
The faint 21 cm signal emitted by neutral hydrogen in cosmic filaments is expected to be detectable. However, due to its weakness, stacking techniques are required. We assessed two…
Distinguishing the nature of dark matter by mapping cosmic filaments from Lyman-alpha emission
Yizhou Liu, Liang Gao, Shihong Liao +3
The standard CDM cosmological model predicts that cosmic filaments are highly clumpy, whereas warm dark matter -- invoked to address small-scale challenges in CDM -- produces…
The impact of cosmic filaments on the abundance of satellite galaxies
Yuxi Meng, Haonan Zheng, Shihong Liao +9
The impact of cosmic web environments on galaxy properties plays a critical role in understanding galaxy formation. Using the state-of-the-art cosmological simulation IllustrisTNG,…
Formation of the dark-matter deficient S0 galaxy NGC 4111 under the tidal interactions
Mei Ai, Ming Zhu, Nai-ping Yu +8
We present the high-sensitivity and large-scale atomic hydrogen (HI) observations towards lenticular (S0) galaxy NGC 4111 using the Five-hundred-meter Aperture Spherical Radio Tele…
