Talk — A Comprehensive View of Far-infrared Fine-structure Lines: New Answers & New Questions
Bo Peng (MPA)
View Abstract
Abstract
The far-infrared fine-structure lines (FIR FSLs), especially [C II]158μm
and [O III]88μm lines, are powerful tools in identifying high redshift
galaxies and studying physical conditions of interstellar medium (ISM).
However, many gaps remain in the study of FIR FSLs, especially between
the study of FIR FSLs and the optical strong lines, and between the low
and high redshift galaxies, which limits our capability in
systematically comparing and combining multi-wavelength observations
from powerful facilities like ALMA and JWST. In this talk, I will
present a comprehensive catalog including most of the global FIR FSL
data of both low- and high-z galaxies collected from the literature
covering a large range of galaxy types, with rich ancillary optical and
mid-infrared data. Based on this comprehensive catalog, I will give a
renewed view of the empirical FIR FSL relations, and demonstrate the
canonical factors behind these lines aided by the photoionization
models. I will highlight the new results enabled by combining the
multi-wavelength data, including the identification of [O III]
contribution from AGN, the coherence between all the neutral and ionized
gas emission in both FIR and optical, the (non-)evolution of some widely
used lines ratios (e.g. [O III]/[C II]), the dichotomy between the
ionized&neutral gas and the dust that results in "line deficit" of, not
only [C II], but all the lines including H alpha, as well as the
consequent crisis of the star formation rate measurement in dusty
galaxies and a quest for an updated view of ISM.
