Hydrogen cyanide (HCN) represents a small but widely distributed fraction of the interstellar molecules, and it has been observed in all the environments characterizing...

Hydrogen cyanide (HCN) and its isomer hydrogen isocyanide (HNC) are omnipresent in the interstellar medium (ISM). The ratio between the two isomers serves as an indicator of...

2024年6月19日 · MUSE Hα and JWST 21 μm maps, with the produced moment-0 maps. This means, we convolve the maps to the 260 pc HCN resolution and reproject them onto the same …

We present new ALMA observations of HCN (1 - - 0) line emission, which traces the dense gas content across the molecular gas disc at 260 pc scales.

Hengchun Airport (Chinese: 恆春機場; pinyin: Héngchūn Jīchǎng) (IATA: HCN, ICAO: RCKW) is an airport in Renshou Village, Hengchun Township, Pingtung County, Taiwan. The airport is near Kenting National Park and is the southernmost airport in Taiwan.

Our results show that the kpc-scale HCN/CO line ratio is a powerful tool to trace the 150 pc scale average density distribution of the molecular clouds. Lastly, we find systematic variations of the SFR/HCN ratio with cloud-scale molecular gas properties, which are incompatible with a universal star formation efficiency.

2024年11月1日 · In this work, we present new ALMA observations of HCN (1−0) at 260 pc scale to test how the amount of dense gas and its ability to form stars varies with environmental properties.

This paper constructs a rovibrational state-specific kinetic mechanism for the HCN system, leveraging electronic structure calculations, classical scattering dynamics, and state-to-state kinetics.

We present interferometric observations of three ultraluminous infrared galaxies (ULIRGs; UGC 5101, Mrk 273, and IRAS 17208-0014) in the 3 mm wavelength range, using the Nobeyama Millimeter Array....
