Talk — A Comprehensive View of Far-infrared Fine-structure Lines: New Answers & New Questions
Bo Peng (MPA)

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.

Talk — Some musings and details on extragalactic distances with the SBF
Michele Cantiello (INAF - SBF)

Abstract

The surface brightness fluctuations (SBF) technique is among the most precise distance indicators across a

range from a few to several hundred Mpc. In this informal discussion, I will highlight the key features of the SBF

methodology, focusing on the origin of the SBF signal and its standardization for distance measurements.
