Detection And Prebiotic Chemistry of Possible Glycine Precursor Molecule Methylenimine Towards The Hot Molecular Core G10.47+0.03
Amino acids are essential for the synthesis of protein. Amino acids contain both amine (R−NH2) and carboxylic acid (R−COOH) functional groups, which help to understand the possible formation mechanism of […]

First Detection in Space of the High-energy Isomer of Cyanomethanimine: H2CNCN
We report the first detection in the interstellar medium of N-cyanomethanimine (H2CNCN), the stable dimer of HCN of highest energy, and the most complex organic molecule identified in space containing […]

Comprehensive Laboratory Constraints On Thermal Desorption Of Interstellar Ice Analogues
To explain grain growth and destruction in warm media, ice mantle formation and sublimation in cold media, and gas line emission spectroscopy, astrochemical models must mimic the gas–solid abundance ratio. […]

Search For Gravitationally Lensed Interstellar Transmissions
We consider interstellar light transmission aided by a gravitational lens. We find that optimal reception efficiency occurs in lensing geometries where the transmitter, lens, and receiver are nearly aligned.

ALMA Unlocks The Chemical Secrets Of A Starburst Galaxy
Astronomers observed with the Atacama Large Millimeter/submillimeter Array (ALMA) the center of a relatively nearby galaxy known as NGC 253, which produces stars at a very high rate.
