First monitoring campaign of a Main-sequence Radio Pulse emitter: the case of CU Vir
Barnali Das, Hayley Bignall, Andrew Zic +6
CU Vir, a magnetic hot star, is the first discovered Main-sequence Radio Pulse emitter (MRP) characterized by its ability to produce periodic radio pulses via electron cyclotron ma…
Time Domain Studies of Active Galactic Nuclei with the SKA telescopes
Hayley Bignall, Rajan Chhetri
Time domain studies of active galactic nuclei (AGN) at radio wavelengths probe physical processes near the central engine via intrinsic variability, in particular within the relati…
The effect of interstellar scattering on coherent radio emission from stars: the case of CU Vir
J. S. Morgan, B. Das, H. E. Bignall
A subset of magnetic stars exhibit periodic radio pulses produced by the coherent electron cyclotron maser mechanism. These pulses are known to exhibit both temporal and spectral v…
One sightline, many systems: a FLASH discovery of HI towards scintillating quasar PKS 0405-385
E. F. Kerrison, H. Yoon, E. M. Sadler +15
We report the discovery of an intervening 21\,cm absorption line at z = 0.882 towards the z = 1.284 quasar PKS 0405-385, identified in the First Large Absorption Survey in HI (FLAS…
