A NICER View of PSR J0030+0451: Millisecond Pulsar Parameter Estimation [PDF]
Astrophysical Journal, 2019 We report on Bayesian parameter estimation of the mass and equatorial radius of the millisecond pulsar PSR J0030+0451, conditional on pulse-profile modeling of Neutron Star Interior Composition Explorer X-ray spectral-timing event data.

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.
