PIConGPU modeling of nanoplasma formation in helium nanodroplets irradiated by intense femtosecond laser pulses
Cristian Medina, Klaus Steiniger, Brian Edward Marre +15
Helium nanodroplets provide a unique and versatile platform for investigating strong-field-driven nanoplasma dynamics. In this work, we present large-scale, GPU-accelerated particl…
Chemical modeling of aminoketene, ethanolamine, and glycine production in interstellar ices
Sydney A. Willis, Serge A. Krasnokutski, Nathaniel J. Morin +1
Icy interstellar dust grains are a source of complex organic molecule (COM) production, although their formation mechanisms are debated. Laboratory experiments show that atomic C d…
Cyclic C as the carrier of the diffuse interstellar band at 503.9 nm?
Serge. A. Krasnokutski, Lisa Ganner, Milan Ončák +5
The diffuse interstellar bands (DIBs) have remained a mystery in astronomy since their discovery over a century ago. The only currently known carrier is C responsible for…
Ly- processing of solid-state Ethanolamine: Potential Precursors to Sugar and Peptide Derivatives
T. Suhasaria, S. M. Wee, R. Basalgète +4
Ethanolamine (EA), a key component of phospholipids, has recently been detected in the interstellar medium within molecular clouds. To understand this observation, laboratory studi…
Infrared Spectra of Solid-State Ethanolamine: Laboratory Data in Support of JWST Observations
T. Suhasaria, S. M. Wee, R. Basalgète +4
Ethanolamine (NHCHCHOH, EA) has been identified in the gas phase of the ISM within molecular clouds. Although EA has not been directly observed in the molecular ice pha…
Formation of extraterrestrial peptides and their derivatives
Serge A. Krasnokutski, Cornelia Jager, Thomas Henning +3
The formation of protein precursors, due to the condensation of atomic carbon under the low-temperature conditions of the molecular phases of the interstellar medium, opens alterna…
Experimental Characterization of the Energetics of Low-temperature Surface Reactions
Thomas K. Henning, Serge A. Krasnokutski
Astrochemical surface reactions are thought to be responsible for the formation of complex organic molecules, which are of potential importance for the origin of life. In a situati…
Formation of the simplest amide in molecular clouds: formamide (NHCHO) and its derivatives in HO-rich and CO-rich interstellar ice analogs upon VUV irradiation
K. -J. Chuang, C. J\{"a}ger, S. A. Krasnokutski +2
The astronomical detection of formamide (NHCHO) toward various star-forming regions and in cometary material implies that the simplest amide might have an early origin in dark…
A pathway to peptides in space through the condensation of atomic carbon
S. A. Krasnokutski, K. -J. Chuang, C. Jäger +2
Organic molecules are widely present in the dense interstellar medium, and many have been synthesized in the laboratory on Earth under the conditions typical for an interstellar en…
The C60:C60+ ratio in diffuse and translucent interstellar clouds
Gaël Rouillé, Serge A. Krasnokutski, Yvain Carpentier
Context. Insight into the conditions that drive the physics and chemistry in interstellar clouds is gained from determining the abundance and charge state of their components. Aims…
A New "Non-energetic" Route to Complex Organic Molecules in Astrophysical Environments: The C + HO HCO Solid-state Reaction
Alexey Potapov, Serge Krasnokutski, Cornelia Jäger +1
The solid-state reaction C + HO HCO was studied experimentally following the codeposition of C atoms and HO molecules at low temperatures. In spite of the…
Did life originate from low-temperature areas of the Universe?
Serge A. Krasnokutski
The biological molecules delivered to Earth on the board of meteorites and comets were called one of the possible causes of the origin of life. Therefore, our understanding of the…
