Kolmogorov analysis of pulsar TOA

Astronomy & Astrophysics
The Kolmogorov stochasticity parameter (KSP) as a sensitive descriptor of the degree of randomness of signals was used to analyze the properties of the NANOGrav pulsar timing data associated with a stochastic gravitational wave background.

Lens Modeling of STRIDES Strongly Lensed Quasars Using Neural Posterior Estimation

The Astronomical Journal
Strongly lensed quasars can be used to constrain cosmological parameters through time-delay cosmography. Models of the lens masses are a necessary component of this analysis.

Redshift Distributions of Fast Radio Bursts Inferred Using Clustering in Dispersion Measure Space

The Astrophysical Journal
Fast radio bursts (FRBs), millisecond-duration radio transient events, possess the potential to serve as excellent cosmological probes. The FRB redshift distribution contains information about the FRB sources, providing key constraints on the types of ...
