The FAST Galactic Plane Pulsar Snapshot survey: I. Project design and pulsar discoveries [PDF]
Research in Astronomy and Astrophysics, 2021 Discovery of pulsars is one of the main goals for large radio telescopes. The Five-hundred-meter Aperture Spherical radio Telescope (FAST), that incorporates an L-band 19-beam receiver with a system temperature of about 20 K, is the most sensitive radio ...

The MeerKAT Pulsar Timing Array: First Data Release [PDF]
Monthly notices of the Royal Astronomical Society, 2022 We present the first 2.5 years of data from the MeerKAT Pulsar Timing Array (MPTA), part of MeerTime, a MeerKAT Large Survey Project. The MPTA aims to precisely measure pulse arrival times from an ensemble of 88 pulsars visible from the Southern ...

Pulsar: Efficient Sphere-based Neural Rendering
Computer Vision and Pattern Recognition, 2021 We propose Pulsar, an efficient sphere-based differentiable rendering module that is orders of magnitude faster than competing techniques, modular, and easy-to-use due to its tight integration with PyTorch.
