Carbon Chain Chemistry in Hot-Core Regions around Three Massive Young Stellar Objects Associated with 6.7 GHz Methanol Masers

Kotomi Taniguchi, Eric Herbst, Liton Majumdar +7

We have carried out observations of CCH (), CHCN (), and three C isotopologues of HCN () toward three massive young stellar objects (MYSOs)…

Photodissociation Region Diagnostics Across Galactic Environments

Thomas G. Bisbas, Jonathan C. Tan, Kei E. I. Tanaka

We present three-dimensional astrochemical simulations and synthetic observations of magnetised, turbulent, self-gravitating molecular clouds. We explore various galactic interstel…

The properties and environment of very young galaxies in the local Universe

M. Trevisan, G. A. Mamon, T. X. Thuan +3

In the local Universe, there is a handful of dwarf compact star-forming galaxies with extremely low oxygen abundances. It has been proposed that they are young, having formed a lar…

Spectral Variability of Radio Sources at Low Frequencies

K. Ross, J. R. Callingham, N. Hurley-Walker +7

Spectral variability of radio sources encodes information about the conditions of intervening media, source structure, and emission processes. With new low-frequency radio interfer…

Dual AGN candidates with double-peaked [O III] lines matching that of confirmed dual AGNs

D. -C. Kim, Ilsang Yoon, A. S. Evans +3

We have performed a spectral decomposition to search for dual active galactic nuclei (DAGNs) in the Sloan Digital Sky Survey (SDSS) quasars with . Potential DAGN candidates…
