Searching for the largest bound atoms in space
K. L. Emig, P. Salas, F. de Gasperin +5
(abridged) Radio recombination lines (RRLs) at frequencies < 250 MHz trace the cold, diffuse phase of the ISM. Next generation low frequency interferometers, such as LOFAR, MWA…
Efficient computation of collisional -mixing rate coefficients in astrophysical plasmas
D. Vrinceanu, R. Onofrio, J. B. R. Oonk +2
We present analytical expressions for direct evaluation of -mixing rate coefficients in proton-excited hydrogen atom collisions and describe a software package for efficient…
Carbon radio recombination lines from gigahertz to megahertz frequencies towards Orion A
P. Salas, J. B. R. Oonk, K. L. Emig +4
Context. The combined use of carbon radio recombination lines (CRRLs) and the 158 m-[CII] line is a powerful tool for the study of the energetics and physical conditions (e.g.,…
Direct estimation of electron density in the Orion Bar PDR from mm-wave carbon recombination lines
S. Cuadrado, P. Salas, J. R. Goicoechea +3
A significant fraction of the molecular gas in star-forming regions is irradiated by stellar UV photons. In these environments, the electron density (n_e) plays a critical role in…
