Pulsar Discoveries from the TRAPUM UHF Survey of Fermi-LAT Sources

Tinn Thongmeearkom, Colin J. Clark, Rene P. Breton +25

The Fermi Large Area Telescope (LAT) provides advantages for radio pulsar searches by enabling efficient target selection. We can confidently point radio telescopes to the position…

GOTO identification and broadband modelling of the counterpart to the SVOM GRB 250818B

S. Belkin, G. P. Lamb, K. Ackley +61

Rapid localisation and follow-up of gamma-ray bursts (GRBs) increasingly rely on low-latency triggers from new missions coupled to wide-field robotic optical facilities. We present…

Optical Study of TRAPUM Pulsars and Modelling of the Redbacks: PSR J10364353 and PSR J18036707

A. Phosrisom, R. P. Breton, C. J. Clark +12

The Transients and Pulsars with MeerKAT (TRAPUM) project discovered eight binary millisecond pulsars in its first shallow \textit{L}-band survey of unidentified \textit{Fermi} -…

Discovery and Analysis of Afterglows from Poorly Localised GRBs with the Gravitational-wave Optical Transient Observer (GOTO) All-sky Survey

Amit Kumar, B. P. Gompertz, B. Schneider +86

Gamma-ray bursts (GRBs), particularly those detected by wide-field instruments such as the Fermi/GBM, pose a challenge for optical follow-up due to their large initial localisation…

Fast Radio Bursts from non-resonant Alfvén waves and synchrotron maser emission in the magnetar wind

Killian Long, Asaf Pe'er

Non-resonant interactions between Alfvén waves and a relativistic plasma result in the formation of the population inversions necessary for synchrotron maser emission (SME) across…

Discovery of the variable optical counterpart of the redback pulsar PSR J2055+1545

Marco Turchetta, Bidisha Sen, Jordan A. Simpson +5

We present the discovery of the variable optical counterpart to PSR J2055+1545, a redback millisecond pulsar, and the first radial velocity curve of its companion star. The multi-b…
