From Dark Matter to Galaxies: Halo-Free Mock Generation via Conditional Point-Cloud Diffusion
Kana Moriwaki, Ken Osato, Naoki Yoshida
We present a diffusion-based generative model for constructing realistic galaxy catalogues from dark matter density fields. The model takes a three-dimensional dark matter density…
Development of TIFUUN: Terahertz Integral Field Units with Universal Nanotechnology
Akira Endo, Tom J. L. C. Bakx, Jochem J. A. Baselmans +50
TIFUUN (THz Integral Field Units with Universal Nanotechnology) is an ultra-wideband mm-submm wave imaging spectrometer that capitalizes on the highly scalable integrated supercond…
Signatures of Accreting Black Holes in Line Intensity Mapping
Erika Ogata, Kana Moriwaki, Adam Lidz +2
Line-intensity mapping (LIM) has attracted growing attention as a powerful technique for probing the large-scale distribution of galaxies and the cosmic history of star formation t…
CosmoGLINT: Cosmological Generative Model for Line Intensity Mapping with Transformer
Kana Moriwaki, Rui Lan Jun, Ken Osato +1
Modelling star-forming galaxies is crucial for upcoming observations of large-scale matter and galaxy distributions with galaxy redshift surveys and line intensity mapping (LIM). W…
Scatter in the star formation rate-halo mass relation: secondary bias and its impact on line-intensity mapping
Rui Lan Jun, Tom Theuns, Kana Moriwaki +1
We use the IllustrisTNG cosmological hydrodynamical simulations to study the impact of secondary bias -- specifically, the correlation between star formation rate (SFR) and halo bi…
The power spectrum of galaxies from large to small scales: a line-intensity mapping perspective
Rui Lan Jun, Tom Theuns, Kana Moriwaki +1
We present a model for the power spectrum of the density field of galaxies weighted by their star formation rate. This weighting is relevant in line-intensity mapping (LIM) when th…
