Hunt for complex cyanides in protostellar ices with JWST: Tentative detection of CHCN and CHCN

P. Nazari, W. R. M. Rocha, A. E. Rubinstein +20

Nitrogen-bearing complex organic molecules have been commonly detected in the gas phase but not yet in interstellar ices. This has led to the long-standing question of whether thes…

Water ice: temperature-dependent refractive indexes and their astrophysical implications

W. R. M. Rocha, M. G. Rachid, M. K. McClure +2

Interstellar ices are largely composed of frozen water. It is important to derive fundamental parameters for HO ice such as absorption and scattering opacities for which accura…

CoCCoA: Complex Chemistry in hot Cores with ALMA. Selected oxygen-bearing species

Y. Chen, M. L. van Gelder, P. Nazari +22

Complex organic molecules (COMs) have been observed to be abundant in the gas phase toward protostars. Deep line surveys have been carried out only for a limited number of well-kno…

The hunt for formamide in interstellar ices: A toolkit of laboratory infrared spectra in astronomically relevant ice mixtures and comparisons to ISO, Spitzer, and JWST observations

Katerina Slavicinska, Marina Gomes Rachid, Will Robson Monteiro Rocha +3

This work aims at characterizing the mid-IR spectra of formamide in its pure form as well as in mixtures of the most abundant interstellar ices via laboratory simulation of such ic…

An Ice Age JWST inventory of dense molecular cloud ices

M. K. McClure, W. R. M. Rocha, K. M. Pontoppidan +39

Icy grain mantles are the main reservoir of the volatile elements that link chemical processes in dark, interstellar clouds with the formation of planets and composition of their a…

LIDA - The Leiden Ice Database for Astrochemistry

W. R. M. Rocha, M. G. Rachid, B. Olsthoorn +3

High quality vibrational spectra of solid-phase molecules in ice mixtures and for temperatures of astrophysical relevance are needed to interpret infrared observations toward proto…

Infrared spectra of complex organic molecules in astronomically relevant ice mixtures. V. Methyl cyanide (acetonitrile)

Marina G. Rachid, Will Rocha, Harold Linnartz

The increasing sensitivity and resolution of ground-based telescopes have enabled the detection of gas-phase complex organic molecules (COMs) across a variety of environments. Many…

Refractive index and extinction coefficient of vapor-deposited water ice in the UV-Vis range

Jiao He, Sharon J. M. Diamant, Siyu Wang +4

Laboratory results of the optical properties of vapor-deposited water ice, specifically the refractive index and extinction coefficient, are available mainly for a selective set of…
