Search and identification of transient and variable radio sources using MeerKAT observations: a case study on the MAXI J1820+070 field [PDF]
, 2022 Many transient and variable sources detected at multiple wavelengths are also observed to vary at radio frequencies. However, these samples are typically biased towards sources that are initially detected in wide-field optical, X-ray or gamma-ray surveys.

Diverse origins for non-repeating fast radio bursts: Rotational radio transient sources and cosmological compact binary merger remnants [PDF]
Astronomy & Astrophysics, 2023 A large number of fast radio bursts (FRBs) detected with the CHIME telescope have enabled investigations of their energy distributions in different redshift intervals, incorporating the consideration of the selection effects of CHIME.

Strongly Lensed Transient Sources: A Review [PDF]
Chinese Physics Letters, 2022 The past decades have witnessed a lot of progress in gravitational lensing with two main targets: stars and galaxies (with active galactic nuclei). The success is partially attributed to the continuous luminescence of these sources making the detection ...

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.

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.

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
