Water enhances the formation of refractory sulfur in interstellar ices
Carlos del Burgo Olivares, Hector Carrascosa, Guillermo M. Muñoz Caro +3
Sulfur is the tenth most abundant element in space, yet it is strongly depleted in the gas phase of dense interstellar regions, suggesting sequestration in dust grain components th…
Photodesorption of SO2 and SO from UV-irradiated SO2 ices
Rafael Martín-Doménech, Bruno Escribano, David Navarro-Almaida +4
The detection of high gas-phase abundances of SO2 and SO in the cold envelope of an intermediate mass protostar suggests that these molecules might form on icy dust grains and subs…
The sulfur plume in the Horsehead nebula: New detections of SH, SH, and CO
Asunción Fuente, Gisela Esplugues, Pablo Rivière-Marichalar +13
Sulfur is essential for life, but its abundance and distribution in the interstellar medium remain uncertain, with over 90% of sulfur undetected in cold molecular clouds. Sulfur al…
Infrared spectroscopy of astrophysical ice analogs at oblique angles
Cristóbal González Díaz, Hector Carrascosa, Guillermo M. Muñoz Caro
In astrochemical exploration, infrared (IR) spectroscopy is vital for understanding the composition and structure of ice in various space environments. This article explores the im…
Predicting the detectability of sulphur-bearing molecules in the solid phase with simulated spectra of JWST instruments
A. Taillard, R. Martín-Doménech, H. Carrascosa +7
To date, gas phase observations of sulphur in dense interstellar environments have only constrained the molecular carriers of 1% of its predicted cosmic abundance. An additional 5%…
Formation and desorption of sulfur chains (HS and S) in cometary ice: effects of ice composition and temperature
H. Carrascosa, G. M. Muñoz Caro, R. Martín-Doménech +3
The reservoir of sulfur accounting for sulfur depletion in the gas of dense clouds and circumstellar regions is still unclear. One possibility is the formation of sulfur chains, wh…
Characterization of carbon dioxide on Ganymede and Europa supported by experiments: Effects of temperature, porosity, and mixing with water
L. Schiltz, B. Escribano, G. M. Muñoz Caro +8
The surfaces of icy moons are primarily composed of water ice that can be mixed with other compounds, such as carbon dioxide. The carbon dioxide (CO stretching fundamental ban…
UV-photoprocessing of acetic acid (CH3COOH)-bearing interstellar ice analogs
C. del Burgo Olivares, H. Carrascosa, B. Escribano +2
Acetic acid (CH3COOH) was detected in the gas toward interstellar clouds, hot cores, protostars and comets. Its formation in ice mantles was proposed and acetic acid awaits detecti…
Physical properties of methanol (CHOH) ice as a function of temperature: Density, infrared band strengths, and crystallization
H. Carrascosa, M. Á. Satorre, B. Escribano +2
The presence of methanol among the common ice components in interstellar clouds and protostellar envelopes has been confirmed by the James Webb Space Telescope. Methanol is often d…
Density and infrared band strength of interstellar carbon monoxide (CO) ice analogues
Cristóbal González Díaz, Hector Carrascosa, Guillermo M. Muñoz Caro +2
The motivation to study experimentally CO ice under mimicked interstellar conditions is supported by the large CO gas abundances and ubiquitous presence of CO in icy grain mantles.…
Thermal Conductivity measurements of macroscopic frozen Salt Ice analogs of Jovian Icy moons in support of the planned JUICE mission
Cristóbal González Díaz, Sofia Aparicio Secanellas, Guillermo M. Muñoz Caro +9
The study of thermal properties of frozen salt solutions representative of ice layers in Jovian moons is crucial to support the JUpiter ICy moons Explorer (JUICE) (ESA) and Europa…
Photoprocessing of H2S on dust grains: building S chains in translucent clouds and comets
S. Cazaux, H. Carrascosa, G. M. Munoz Caro +4
Context. Sulfur is used as a tracer of the evolution from interstellar clouds to stellar systems. However, most of the expected sulfur in molecular clouds remains undetected. Sulfu…
Synthesis of the first nitrogen-heterocycles in interstellar ice analogs containing methylamine (CHNH) exposed to UV radiation: Formation of trimethylentriamine (TMT, c-(-CH-NH)) and hexamethylentetramine (HMT, (CH)N)
H. Carrascosa, C. González Díaz, G. M. Muñoz Caro +2
Hexamethylentetramine has drawn a lot of attention due to its potential to produce prebiotic species. This work aims to gain a better understanding in the chemical processes concer…
2-aminooxazole in astrophysical environments: IR spectra and destruction cross sections for energetic processing
Belén Maté, Ricardo Carrasco-Herrera, Vicente Timón +6
2-aminooxazole (2AO), a N-heterocyclic molecule, has been proposed as an intermediate in prebiotic syntheses. It has been demonstrated that it can be synthesized from small molecul…
Photon-induced desorption of larger species in UV-irradiated methane (CH4) ice
H. Carrascosa, G. A. Cruz-Díaz, G. M. Muñoz Caro +2
At the low temperatures found in the interior of dense clouds and circumstellar regions, along with HO and smaller amounts of species such as CO, CO, or CHOH, the infra…
CO and CO ice mixtures with N in photon energy transfer studies
H. Carrascosa, L. -C. Hsiao, N. -E. Sie +2
In dense clouds of the interstellar medium, dust grains are covered by ice mantles, dominated by HO. CO and CO are common ice components observed in infrared spectra, while…
