Chemodynamics of BoötesI with : Revised Velocity Gradient, Dark Matter Density, and Galactic Chemical Evolution Constraints
Nathan R. Sandford, Ting S. Li, Sergey E. Koposov +14
We combine new spectroscopic observations of the ultra faint dwarf galaxy (UFD) Boötes I (Boo I) from the Southern Stellar Stream Spectroscopic Survey () with 15 years…
Cusp-to-Core Transition of Dark Matter Halos across Galaxy Mass Scales
Kohei Hayashi, Yuka Kaneda, Masao Mori +1
We investigate the diversity of dark matter (DM) density profiles in a large sample of late-type galaxies from the SPARC database, with the goal of testing whether a cusp-to-core t…
JFlow: Model-Independent Spherical Jeans Analysis using Equivariant Continuous Normalizing Flows
Sung Hak Lim, Kohei Hayashi, Shun'ichi Horigome +2
The kinematics of stars in dwarf spheroidal galaxies have been studied to understand the structure of dark matter halos. However, the kinematic information of these stars is often…
When Does Metadata Conditioning (NOT) Work for Language Model Pre-Training? A Study with Context-Free Grammars
Rei Higuchi, Ryotaro Kawata, Naoki Nishikawa +7
The ability to acquire latent semantics is one of the key properties that determines the performance of language models. One convenient approach to invoke this ability is to prepen…
CFTM: Continuous time fractional topic model
Kei Nakagawa, Kohei Hayashi, Yugo Fujimoto
In this paper, we propose the Continuous Time Fractional Topic Model (cFTM), a new method for dynamic topic modeling. This approach incorporates fractional Brownian motion~(fBm) to…
