Coherent radio bursts, polarity reversal, and quiescent emission from the M4V dwarf WW PsA
Jackson Mitchell-Bolton, Laura Driessen, Tara Murphy +6
Coherent radio emission from magnetically active M dwarfs is largely observed in two varieties: stochastic solar-like bursts and beamed, rotationally modulated emission including a…
The birth and fate of stellar clumps in super-early galaxies
B. Das, A. Ferrara, A. Pallottini +2
(Abridged) JWST has revealed extremely compact stellar clumps in galaxies at z>6, but their formation mechanism and subsequent evolution remain uncertain. We investigate whether su…
On the clumpy nature of super-early galaxies
A. Ferrara, B. Das, M. Kohandel +2
JWST has revealed that galaxies during the Epoch of Reionization are composed of compact stellar clumps spanning more than two orders of magnitude in mass and size. We present an a…
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…
The Variability of Radio Stars
Laura N. Driessen, Alex Andersson, Joseph R. Callingham +6
Stellar radio emission is highly variable with stellar flares lasting from milliseconds to hours. For some stars, their flares or bursts can repeat once every couple of hours, whil…
GMRT Survey of Radio Emission from Magnetic Massive Stars -- I: Emission from Single Stars at sub-GHz Frequencies
Ayan Biswas, Gregg A. Wade, Barnali Das +2
With the growing subset of magnetic massive stars, it is now possible to conduct a systematic survey of radio emission from magnetic hot stars to better understand the underlying e…
No Blue without Red: Evolutionary Properties of Super-Early Galaxies
A. Ferrara, G. Rodighiero, S. Carniani +3
The discovery of numerous luminous, super-early galaxies at by JWST has revealed a striking diversity in their ultraviolet (UV) properties, ranging from extremely blue, dust…
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…
ASKAP J005512.2-255834: A Luminous, Long-Lived Radio Transient at z = 0.1 -- an Orphan Afterglow or an off-nuclear TDE from an IMBH?
Ashna Gulati, Tara Murphy, David L. Kaplan +24
We report the discovery of a slowly evolving, extragalactic radio transient, ASKAP J005512.2--255834 (hereafter ASKAP J0055-2558), identified using the Australian SKA Pathfinder in…
