Searching for EeV photons with Telescope Array Surface Detector and neural networks
Telescope Array Collaboration, R. U. Abbasi, T. Abu-Zayyad +126
Ultra-high-energy photons play an important role in probing astrophysical models and beyond-Standard-Model scenarios. We report updated limits on the diffuse photon flux using Tele…
Self-Similar Solutions for Geometrically Thin Accretion Disks with Magnetically Driven Winds: Application to Tidal Disruption Events
Mageshwaran Tamilan, Kimitake Hayasaki, Takeru K. Suzuki
We analytically derive self-similar solutions for a time-dependent, one-dimensional, magnetically driven accretion-disk-wind model based on the magnetohydrodynamic equations. The m…
A novel approach to the relationships between data features -- based on comprehensive examination of mathematical, technological, and causal methodology
JaeHong Kim
The expansion of artificial intelligence (AI) has raised concerns about transparency, accountability, and interpretability, with counterfactual reasoning emerging as a key approach…
A novel approach to data generation in generative model
JaeHong Kim, Jaewon Shim
Variational Autoencoders (VAEs) and other generative models are widely employed in artificial intelligence to synthesize new data. However, current approaches rely on Euclidean geo…
Steady-State Solutions for a Geometrically Thin Accretion Disk with Magnetically-Driven Winds
Mageshwaran Tamilan, Kimitake Hayasaki, Takeru K. Suzuki
We present steady-state solutions for a one-dimensional, magnetically-driven accretion disk wind model based on magnetohydrodynamic equations. We assume a geometrically thin, gas-p…
