A Partially Supervised Latent-Space Variational Autoencoder for Generating Neutron Star Equations of State
Tianqi Zhao, Fanglida Yan, Alex Ross +1
We develop a partially supervised latent-space variational autoencoder (PSL-VAE) framework to reconstruct and generate neutron star (NS) equations of state (EOS). The PSL-VAE consi…
A Very Big Video Reasoning Suite
Maijunxian Wang, Ruisi Wang, Juyi Lin +53
Rapid progress in video models has largely focused on visual quality, leaving their reasoning capabilities underexplored. Video reasoning grounds intelligence in spatiotemporally c…
Data-Driven Generation of Neutron Star Equations of State Using Variational Autoencoders
Alex Ross, Tianqi Zhao, Sanjay Reddy
We develop a machine learning model based on a structured variational autoencoder (VAE) framework to reconstruct and generate neutron star (NS) equations of state (EOS). The VAE co…
A New Bayesian Framework with Mass-Radius-Space Priors to Constrain the Neutron Star Equation of State
Boyang Sun, Tianqi Zhao, James M. Lattimer
We propose a new Bayesian framework to infer the neutron star equation of state (EOS) from mass and radius observations and neutron matter theory by defining priors that directly p…
Observable Signatures of a Quarkyonic Phase in Neutron Stars
Probit J Kalita, Tuhin Malik, Tianqi Zhao +2
Quarkyonic matter in \(β\)-equilibrium is a potential description of cold dense matter in neutron stars (NSs), that introduces non-interacting quarks alongside nucleons and leptons…
Suppression of composition -modes in chemically-equilibrating warm neutron stars
Tianqi Zhao, Peter B. Rau, Alexander Haber +3
We investigate the impact of chemical equilibration and the resulting bulk viscosity on non-radial oscillation modes of warm neutron stars at temperatures up to MeV, r…
Characterizing the nuclear models informed by PREX and CREX: a view from Bayesian inference
Tianqi Zhao, Zidu Lin, Bharat Kumar +2
New measurements of the weak charge density distributions of Ca and Pb challenge existing nuclear models. In the post-PREX-CREX era, it is unclear if current models…
Exploring Radial Oscillations in Slow Stable and Hybrid Neutron Stars
Sayantan Ghosh, Sailesh Ranjan Mohanty, Tianqi Zhao +1
In the era of gravitational wave astronomy, radial oscillations hold significant potential for not only uncovering the microphysics behind the internal structure but also investiga…
Framework for phase transitions between the Maxwell and Gibbs constructions
Constantinos Constantinou, Tianqi Zhao, Sophia Han +1
By taking the nucleon-to-quark phase transition within a neutron star as an example, we present a thermodynamically consistent method to calculate the equation of state of ambient…
