We present a suite of Atacama Large Millimeter Array (ALMA) interferometric molecular line
and continuum images that elucidate, on linear size scales of∼ 30–40 au, the chemical …

We investigate the effects produced mainly by broadband soft X-rays up to 2 keV (plus fast
(∼ keV) photoelectrons and low-energy (∼ eV) induced secondary electrons) in the ice …

Absolute total non-dissociative and partial dissociative cross sections of pyrimidine were
measured for electron impact energies ranging from 70 to 400 eV and for proton impact …

Abstract The C 2 H 4 O 2 isomers methyl formate (HCOOCH 3), acetic acid (CH 3 COOH)
and glycoaldehyde (HOCH 2 CHO) have been detected in molecular clouds in the …

Acetone, one of the most important molecules in organic chemistry, also a precursor of
prebiotic species, was found in the interstellar medium associated with star-forming …

The detection of nucleobases, the informational subunits of DNA and RNA, in several
meteorites suggests that these compounds of biological interest were formed via …

Protonation and hydration of biomolecules govern their structure, conformation, and
function. Herein, we explore the microhydration structure in mass-selected protonated …

The desorption process induced by photons, electrons, or ions onto icy surfaces is an
important mechanism for leading neutral or ionized molecular species to the gas phase in …

Studies of interstellar chemistry have grown in number and complexity by both observations
and laboratory measurements, and nitrogen-containing aromatics have been implicated as …
