RRAT J1913+1330: An Extremely Variable and Puzzling Pulsar

The Astrophysical Journal
Rotating radio transients (RRATs) are neutron stars that emit sporadic radio bursts. We detected 1955 single pulses from RRAT J1913+1330 using the 19 beam receiver of the Five-hundred-meter Aperture Spherical radio Telescope.

EAA: Adapting the Segment Anything Model for Perception-driven Astronomical Source Extraction

The Astrophysical Journal Supplement Series
Source extraction is a fundamental task in astronomical data analysis, yet existing methods are often specialized to specific instruments, spectral bands, or imaging conditions, which limits their generalizability.

Follow-up Observations of Apparently One-off Sources from the Parkes Telescope

The Astrophysical Journal
A small fraction of fast radio bursts (FRBs) have been observed with multiple bursts, whereas most Galactic sources emitting radio pulses are known to repeat.

Flat Tails in Fast Radio Burst and Pulsar Energy Distributions: Implications for Optimizing Nearby Fast Radio Burst Surveys

The Astrophysical Journal
Fast radio bursts (FRBs) are energetic, short-duration radio pulses of unclear origin. To explore effective survey strategies for detecting FRBs from nearby globular clusters (GCs), we investigate the burst energy distribution, which has a strong ...

Evidence for Gravitational Lensing in FRB 20190320B: A Potential Lens Mass of ∼420 Solar Masses

The Astrophysical Journal
Due to their millisecond-duration pulses and high flux, fast radio bursts (FRBs) are ideal probes for detecting low-mass gravitational lensing signals, as their distinctive characteristics make them highly sensitive to subtle time delays and lensing ...

Prediction of Multiwavelength Afterglows Associated with FRB 20200120E and FRB 20201124A

The Astrophysical Journal
Fast radio bursts (FRBs) are mysterious radio transients with uncertain origins and environments. Recent studies suggest that some active FRBs may originate from compact objects in binary systems.

Flux Variations of Fast Radio Bursts and Their Persistent Radio Sources: Evidence for a Shared Progenitor

The Astrophysical Journal
Fast radio bursts (FRBs) are millisecond-duration extragalactic radio transients, some of which are associated with compact persistent radio sources (PRSs), hinting at a physical connection.
