Fifteen new millisecond pulsars in 47 Tucanae
W. Chen, D. Risbud, P. C. C. Freire +16
47 Tucanae is one of the largest, brightest, and closest globular clusters to Earth. It hosts an exotic stellar population with stellar dynamics that indicate a complex evolution h…
A joint MeerKAT and Parkes view of Omega Centauri: New TRAPUM Searches and Pulsar Timing
Miquel Colom i Bernadich, Shi Dai, Federico Abbate +27
Millisecond pulsars (MSPs) are powerful probes of globular clusters (GCs), tracing stellar evolution, cluster dynamics, and the local gravitational potential. We investigate the MS…
PSR J00247204ai: a massive, eccentric binary system in the globular cluster 47 Tucanae
D. Risbud, A. Ridolfi, P. C. C. Freire +9
In this paper we present PSR J00247204ai, a 13.026-ms binary pulsar recently discovered in the globular cluster 47 Tucanae by the MeerKAT radio telescope. This is the slowest sp…
Tidal Tails of Nearby Open Clusters. II. A Review of Simulated Properties and the Reliability of Observational Catalogues
Vikrant V. Jadhav, Dhanraj Risbud, Pavel Kroupa +1
Context: Recent studies using Gaia data have reported tidal tail detections for tens to hundreds of open clusters. However, a comprehensive assessment of the reliability & complete…
Tidal tails of nearby open clusters I. Mapping with Gaia DR3
Dhanraj Risbud, Vikrant V. Jadhav, Pavel Kroupa
Context: Tidal tails of open clusters are the result of stellar evaporation from the cluster through the Galactic potential and internal dynamics. With the recent availability of h…
