Long-Period Radio Transient Catalog
LPT-Cat is a curated, literature-based catalog of long-period radio transients (LPTs) — a recently recognized and still mysterious population of radio sources characterized by minute- to hour-long periodicities.
The catalog compiles published LPTs from the literature and presents their key observational properties in a searchable, web-based format.
🌐 Live site: https://psr-jake.github.io/lptcat/
The catalog includes, when available:
- Source name
- Equatorial and Galactic coordinates (with uncertainties)
- Spin period and spin-down constraints
- Dispersion measure (DM) and rotation measure (RM)
- Duty cycle
- Notes
- Discovery and follow-up references
Measurement uncertainties and upper limits on spin-down rates are quoted at the 1σ level when available.
