Cosmic anisotropy and fast radio bursts [PDF]

Classical and Quantum Gravity, 2020
In the recent years, the field of fast radio bursts (FRBs) is thriving and growing rapidly. It is of interest to study cosmology by using FRBs with known redshifts. In the present work, we try to test the possible cosmic anisotropy with the simulated FRBs. In particular, we only consider the possible dipole in FRBs, rather than the cosmic anisotropy in

LOFAR tied-array imaging and spectroscopy of solar S bursts [PDF]

, 2015
Context. The Sun is an active source of radio emission that is often associated with energetic phenomena ranging from nanoflares to coronal mass ejections (CMEs).

Radio fiber bursts and fast magnetoacoustic wave trains

, 2012
We present a model for dm-fiber bursts that is based on assuming fast sausage magnetoacoustic wave trains that propagate along a dense vertical filament or current sheet.

Flux Calibration of CHIME/FRB Intensity Data

The Astronomical Journal, 2023
Fast radio bursts (FRBs) are bright radio transients of microsecond to millisecond duration and unknown extragalactic origin. Central to the mystery of FRBs are their extremely high characteristic energies, which surpass the typical energies of other ...

Solar Decimetre Radio Bursts [PDF]

Australian Journal of Physics, 1963
High resolution studies (2' of arc beam) were made with the east·west arm of the Christiansen radio interferometer for about 50 21·cm solar burst events during 1958-1961. The burst sources were always closely associated in position with already existing radio plage regions of the Sun's slowly varying decimetre radiation.

Statistical geoeffectiveness of solar-interplanetary disturbance events of type II radio bursts and CMEs/shocks

Frontiers in Astronomy and Space Sciences
Understanding and predicting the geoeffectiveness of solar activity on Earth is crucial for space weather. Therefore, predicting the impact of coronal mass ejections (CMEs) and their associated interplanetary (IP) shocks on Earth is essential ...

Statistical Survey of Type III Radio Bursts at Long Wavelengths Observed by the Solar TErrestrial RElations Observatory (STEREO)/Waves Instruments: Goniopolarimetric Properties and Radio Source Locations

, 2014
We have performed statistical analysis of a large number of Type III radio bursts observed by STEREO between May 2007 and February 2013. Only intense, simple, and isolated cases have been included in our data set. We have focused on the goniopolarimetric

Self-modulation of fast radio bursts [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT Fast radio bursts (FRBs) are extreme astrophysical phenomena entering the realm of non-linear optics, a field developed in laser physics. A classical non-linear effect is self-modulation. We examine the propagation of FRBs through the circumburst environment using the idealized setup of a monochromatic linearly polarized GHz ...

Fine structure events in microwave emission during solar minimum

Solar-Terrestrial Physics, 2019
The solar minimum is a period with a relatively smaller number of sunspots and solar eruptions, and has been less studied before. Since the radio signal rapidly responds to the change of solar plasma and magnetic field, we perform a comprehensive ...
