FitsMap: A Simple, Lightweight Tool For Displaying Interactive Astronomical Image and Catalog Data
As the scale of astronomical image and catalog data continues to grow, visualizing the data becomes increasingly difficult.

A Survey of General Relativistic Magnetohydrodynamic Models for Black Hole Accretion Systems
We study the flow of conserved quantities in our simulations and find mass, angular momentum, and energy transport in SANE accretion flows to be primarily inward and fluid-dominated.

A proposal for community driven and decentralized astronomical databases and the Open Exoplanet Catalogue
It is the only catalogue that can correctly represent the orbital structure of planets in arbitrary binary, triple and quadruple star systems, as well as orphan planets.

4-OGC: Catalog of gravitational waves from compact-binary mergers
We present the fourth Open Gravitational-wave Catalog (4-OGC) of binary neutron star (BNS), binary black hole (BBH) and neutron star-black hole (NSBH) mergers.

Detecting Gravitational Waves in Data with Non-Gaussian Noise
Searches for gravitational waves crucially depend on exact signal processing of noisy strain data from gravitational wave detectors, which are known to exhibit significant non-Gaussian behavior.

Testing interacting dark energy with Stage IV cosmic shear surveys through differentiable neural emulators
We employ a novel framework for accelerated cosmological inference, based on neural emulators and gradient-based sampling methods, to forecast constraints on dark energy models from Stage IV cosmic shear surveys.

We present a new, cosmologically model-independent, statistical analysis of the Pantheon+ type Ia supernovae spectroscopic dataset, improving a standard methodology adopted by Lane et al. We use the Tripp equation for supernova standardisation alone, thereby avoiding any potential correlation in the stretch and colour distributions.
