Prof. Zhao Yinghe from the Yunnan Observatories of the Chinese Academy of Sciences, along with collaborators, have conducted a study examining the correlation between the [C II] 158 micron emission and the CO(1−0) line. Their findings were published in The Astrophysical Journal.
Molecular gas (H2) plays a critical role in star formation, a key factor in the evolution of galaxies. Therefore, measuring the gas content in galaxies is crucial. However, the traditional tracer for H2 mass, the CO(1−0) line, is challenging to detect in the early universe due to various factors, including lower metal content.
As a result, there is a pressing need for alternative H2 tracers, especially as more galaxies at high redshifts are being discovered.
Which two emissions or lines were correlated in the research, and what are their specific wavelengths or identifiers? Regard Magister Akuntansi
