A study of the long-term flux density variation of PSRs B0329+54 and B1508+55

, 2004
We have observed the flux densities of PSRs B0329+54 and B1508+55 for 460 days at 327 MHz using the 25 m telescope of NAOC Urumqi Observatory. The flux density time series and the corresponding structure functions are presented. Our observational results

Decoding the cosmological baryonic fluctuations using localized fast radio bursts [PDF]

Astronomy & Astrophysics
The enigma of the missing baryons poses a prominent and unresolved problem in astronomy. Dispersion measures (DM) serve as a distinctive observable of fast radio bursts (FRBs). They quantify the electron column density along each line of sight and reveal
