Particle Acceleration in Mildly Relativistic Outflows of Fast Energetic Transient Sources [PDF]
Universe, 2022 Recent discovery of fast blue optical transients (FBOTs)—a new class of energetic transient sources—can shed light on the long-standing problem of supernova—long gamma-ray burst connections.

A transient radio source consistent with a merger-triggered core collapse supernova [PDF]
Science, 2021 Radio evidence of a stellar merger Core collapse supernovae occur when a massive star exhausts its fuel and explodes. Theorists have predicted that a similar explosion could occur if an evolved massive star merges with a compact companion, such as a neutron star. Dong et al . have identified a radio source

Improved time-delay lens modelling and H0 inference with transient sources [PDF]
, 2021 Strongly lensed explosive transients such as supernovae, gamma-ray bursts, fast radio bursts, and gravitational waves are very promising tools to determine the Hubble constant (H0) in the near future in addition to strongly lensed quasars.

X-Ray and Radio Monitoring of the Neutron Star Low-mass X-Ray Binary 1A 1744-361: Quasiperiodic Oscillations, Transient Ejections, and a Disk Atmosphere [PDF]
Astrophysical Journal, 2023 We report on X-ray (NICER/NuSTAR/MAXI/Swift) and radio (MeerKAT) timing and spectroscopic analysis from a 3 month monitoring campaign in 2022 of a high-intensity outburst of the dipping neutron star low-mass X-ray binary 1A 1744−361.

A Population Study of the Radio Emission of Fast Blue Optical Transients
The Astrophysical Journal, 2023 Despite the fact that the progenitor of fast blue optical transients (FBOTs) is still a subject of debate, FBOTs are sometimes suggested to originate from the core collapse of ultra-stripped stars and be powered by a spinning-down neutron star. Following

Two extreme steep-spectrum, polarized radio sources towards the Galactic bulge [PDF]
Monthly notices of the Royal Astronomical Society, 2021 From an on-going survey of the Galactic bulge, we have discovered a number of compact, steep spectrum radio sources. In this study, we have carried out more detailed observations for two of these sources, located 43 arcmin and 12${_{.}^{\circ}}$7 from ...

The hybrid radio/X-ray correlation of the black hole transient MAXI J1348–630 [PDF]
, 2021 Black hole low mass X-ray binaries in their hard spectral state are found to display two different correlations between the radio emission from the compact jets and the X-ray emission from the inner accretion flow.
