Systematic Study of the Inner Structure of Molecular Tori in Nearby U/LIRGs using Velocity Decomposition of CO Rovibrational Absorption Lines

Shusuke Onishi, Takao Nakagawa, Shunsuke Baba +6

Determining the inner structure of the molecular torus around an active galactic nucleus is essential for understanding its formation mechanism. However, spatially resolving the to…

Spectroscopic Constraints on the Mid-Infrared Attenuation Curve: I -- Attenuation Model using PAH Emission

Thomas S. -Y. Lai, J. D. T. Smith, Els Peeters +4

We introduce a novel model to spectroscopically constrain the mid-infrared (MIR) extinction/attenuation curve from 3--17 um, using Polycyclic Aromatic Hydrocarbon (PAH) emission dr…

Balmer Decrement Anomalies in Galaxies at z ~ 6 Found by JWST Observations: Density-Bounded Nebulae or Excited H I Clouds?

Hiroto Yanagisawa, Masami Ouchi, Kimihiko Nakajima +11

We investigate the physical origins of the Balmer decrement anomalies in GS-NDG-9422 (Cameron et al. 2023) and RXCJ2248-ID (Topping et al. 2024) galaxies at whose $\mathr…
