A Brief Review on the Statistical Properties of Fast Radio Bursts
Yu Sang, Hai-Nan Lin
Fast radio bursts (FRBs) are millisecond-duration radio transients of extragalactic origin, whose emission mechanisms and progenitors remain unresolved. Statistical analyses of the…
Forecast on Gravity with HI 21cm Intensity Mapping Surveys
Yanling Song, Yu Sang, Linfeng Xiao +1
Modified gravity theories offer a well-motivated extension of General Relativity and provide a possible explanation for the late-time accelerated expansion of the Universe. Among t…
Unveiling the distribution and redshift dependence of host galaxy dispersion measures using localized fast radio bursts
Yu Sang, Hai-Nan Lin
Fast Radio Bursts (FRBs) are enigmatic radio pulses whose origins are poorly understood. The dispersion measure of host galaxy () provides critical insights into t…
Quantifying the memory and dynamical stability of magnetar bursts
Yu Sang, Hai-Nan Lin
The time series of energy and waiting time of magnetar bursts carry important information about the source activity. In this paper, we investigate the memory and dynamical stabilit…
Quantifying the randomness and scale invariance of the repeating fast radio bursts
Yu Sang, Hai-Nan Lin
The statistical properties of energy and waiting time carry essential information about the source of repeating fast radio bursts (FRBs). In this paper, we investigate the randomne…
The BINGO Project IX: Search for Fast Radio Bursts -- A Forecast for the BINGO Interferometry System
Marcelo V. dos Santos, Ricardo G. Landim, Gabriel A. Hoerning +19
The Baryon Acoustic Oscillations (BAO) from Integrated Neutral Gas Observations (BINGO) radio telescope will use the neutral Hydrogen emission line to map the Universe in the redsh…
The temporally evolving energy and waiting time statistics of two repeating fast radio bursts
Yu Sang, Hai-Nan Lin
Based on two very large samples of repeating fast radio bursts (FRBs), i.e. FRB 20121102A and FRB 20201124A observed by the FAST telescope, we study the statistical properties of e…
Probing the anisotropic distribution of baryon matter in the Universe using fast radio bursts
Hai-Nan Lin, Yu Sang
We propose that fast radio bursts (FRBs) can be used as the probes to constrain the possible anisotropic distribution of baryon matter in the Universe. Monte Carlo simulations show…
Statistical similarity between soft gamma repeaters and the repeating fast radio bursts
Yu Sang, Hai-Nan Lin
We study the statistical properties of the soft gamma repeater SGR 1935+2154. We find that the cumulative distributions of duration, waiting time, fluence and flux can be well fitt…

Carlos A. Wuensche, Elcio Abdalla, Filipe Batoni Abdalla +48
BINGO (BAO from Integrated Neutral Gas Observations) is a unique radio telescope designed to map the intensity of neutral hydrogen distribution at cosmological distances, making th…
Oscillons during Dirac-Born-Infeld Preheating
Yu Sang, Qing-Guo Huang
Oscillons are long-lived, localized, oscillating nonlinear excitations of a real scalar field which can be abundantly produced during preheating after inflation. We give the first…
