The influence of plasma lensing magnification to the luminosity function of fast radio bursts
Xinzhong Er, Weishan Zhu, Shude Mao +1
Small scale clumps of ionized gas have been suggested by observations in interstellar medium and circumgalactic medium. The propagation of radio signals can be deflected by these p…
A Tale of Two Origins: In-Situ versus Accreted Nitrogen-Rich Field Stars in the MW
Yi Qiao, Baitian Tang, José G. Fernández-Trincado +14
Spectroscopic surveys have identified significant numbers of metal-poor nitrogen-rich (N-rich) field stars. These stars are strong candidates for escapees from globular clusters (G…
Constraining the Baryon Content of Cosmic Filaments Using Localized Fast Radio Bursts and DESI Imaging Data
Jian-Feng Mo, Weishan Zhu, Qi-Rui Yang +2
Cosmic filaments are thought to host a substantial fraction of the missing baryons at redshifts . In this study, we constraint the baryonic content of these filaments using lo…
On the width and profiles of cosmic filaments
Qi-Rui Yang, Weishan Zhu, GuangYao Yu +3
We investigated the widths and profiles of cosmic filaments using the IllustrisTNG simulations. Filaments were identified with DisPerSE, using galaxy samples in simulations as inpu…
Tracing Missing Baryons in the Cosmic Filaments with tSZ and CMB-Lensing Stacking
Jianzhuo Li, Yi Zheng, Weishan Zhu
We investigate the distribution of missing baryons in the cosmic filaments by stacking filaments across the northern and southern SDSS sky regions using Planck Compto…
