Intra-night optical variability and radio characteristics of extremely radio-loud narrow-line Seyfert 1 galaxies
Narrow-line Seyfert 1 galaxies (NLS1s) are generally known to be radio-quiet Active Galactic Nuclei (AGN), but a tiny subset of them are found to be extremely radio-loud with radio loudness parameter ($R_{\rm 1.4~GHz}$) $>$ 100. Given their rarity we investigated intra-night optical variability (INOV) and radio characteristics of a sample of 16 extremely radio-loud NLS1s. For all but four sample sources we report intra-night photometric monitoring for the first time with at least one monitoring…

A Unified Volumetric Rate-Energy Relation from Magnetar Radio Bursts to Fast Radio Bursts
Fast radio bursts (FRBs) are millisecond radio pulses with extremely high bright temperature. Their physical origin is still a mystery. The discovery of FRB 20020428 supports the idea that at least a portion of FRBs is generated by magnetars. However, FRB 20200428 and other radio bursts of SGR 1935+2154 are much less energetic than that of extragalactic FRBs. Thus, whether the progenitors of extragalactic FRBs are magnetars is still in controversy. Here, we investigate the volumetric rates of r…

Stellar Mass-Dispersion Measure Correlations Constrain Baryonic Feedback in Fast Radio Burst Host Galaxies
Low redshift fast radio bursts (FRBs) provide robust measurements of the host-galaxy contribution to the dispersion measure (DM), which can constrain the circumgalactic medium (CGM) of the hosts. We curate a sample of 20 nearby FRBs with low scattering timescales and face-on host galaxies with stellar masses ranging from $10^9 < M^* / M_\odot < 10^{11}$. We fit the distribution of the host galaxy DM to a quadratic model as a function of stellar mass with a mass-independent scatter and find that…

InverTwin: Solving Inverse Problems via Differentiable Radio Frequency Digital Twin
Digital twins (DTs), virtual simulated replicas of physical scenes, are transforming various industries. However, their potential in radio frequency (RF) sensing applications has been limited by the unidirectional nature of conventional RF simulators. In this paper, we present InverTwin, an optimization-driven framework that creates RF digital twins by enabling bidirectional interaction between virtual and physical realms. InverTwin overcomes the fundamental differentiability challenges of RF o…

Modelling gyrosynchrotron emission from coronal energetic electrons in a CME flux rope
Solar flares and coronal mass ejections (CMEs) can accelerate electrons, causing bursts such as type IV emissions in the solar radio continuum. Although radio spectroscopy is a powerful diagnostic tool for the corona, the origin and mechanisms of type IV bursts remain uncertain. In situ measurements can occasionally shed some light on these mechanisms, but they are limited in space and time. Sophisticated numerical modelling offers the best approach to improve our understanding of the physical …

Sometimes I'm silly. Noticed that a fire camera I was watching showed a clock over a minute ahead of my system time, assumed the problems was me. Installed Chrony (Linux Mint, recent Win convert so I'm hardly a power user) and spent the usual 20 minutes farting around with it. Couldn't seem to get it right.
Finally realized my clock IS within a handful of microseconds of the NTP server; it's the clock on the camera that's wrong. D'oh.

Radio Observations of a Candidate Redback Millisecond Pulsar: 1FGL J0523.5-2529
Redback pulsars are a subclass of millisecond pulsar system with a low-mass non-degenerate companion star being ablated by the pulsar. They are of interest due to the insights they can provide for late-stage pulsar evolution during the recycling process. J0523.5-2529 is one such candidate where redback-like emission has been seen at multiple wavelengths except radio. It is a system with a binary orbit of 16.5 hours and a low-mass non-degenerate companion of approximately 0.8 solar masses. The a…

High-resolution Radio Study of Pulsar Wind Nebula MSH 15-52 and Supernova Remnant RCW 89
We present high-resolution radio observations of the pulsar wind nebula (PWN) MSH15-52, which is renowned for its distinctive hand-like shape, and its associated supernova remnant RCW 89. Using the Australia Telescope Compact Array (ATCA), we obtained 3 and 6,cm radio maps with a resolution of 2 arcsec. These unveil small-scale radio features in the system and allow a direct comparison with the arcsecond-resolution X-ray images. We find that the radio emission is composed of a complex filamenta…

A new long period radio transient: Discovery of pulses repeating every 1.16 hours from ASKAP J175534.9-252749.1
We report the discovery of several new pulses from the source ASKAP J175534.9-252749.1 (J1755-2527), originally identified from a single 2-min long pulse, confirming it as a long period transient (LPT) with a period of ~1.16 hours. The pulses are significantly scattered, consistent with Galactic electron density models. Two of the new pulses also had measurable polarisation, but unlike the originally detected pulse, the polarisation angle does not behave as expected from the rotating vector mod…

The radio flare and multi-wavelength afterglow of the short GRB 231117A: energy injection from a violent shell collision
We present the early radio detection and multi-wavelength modeling of the short gamma-ray burst (GRB) 231117A at redshift $z=0.257$. The Australia Telescope Compact Array automatically triggered a 9-hour observation of GRB 231117A at 5.5 and 9 GHz following its detection by the Neil Gehrels Swift Observatory just 1.3 hours post-burst. Splitting this observation into 1-hour time bins, the early radio afterglow exhibited flaring, scintillating and plateau phases. The scintillation allowed us to p…

1D Vlasov Simulations of QED Cascades Over Pulsar Polar Caps
Recent developments in the study of pulsar radio emission revealed that the microphysics of quantum electrodynamic (QED) pair cascades at pulsar polar caps may be responsible for generating the observed coherent radio waves. However, modeling the pair cascades in the polar cap region poses significant challenges, particularly under conditions of high plasma multiplicity. Traditional Particle-in-Cell (PIC) methods often face rapidly increasing computational costs as the multiplicity grows expone…
