Destruction and multiple ionization of PAHs by X-rays in circumnuclear regions of AGNs
Thiago Monfredini, Heidy M. Quitián-Lara, Felipe Fantuzzi +6
The infrared signatures of polycyclic aromatic hydrocarbons (PAHs) are observed in a variety of astrophysical objects, including the circumnuclear medium of active galactic nuclei…
Anharmonic transitions in nearly dry L-cysteine I
T. A. Lima, E. T. Sato, E. T. Martins +7
Two special dynamical transitions of universal character have been recently observed in macromolecules at K and K. Despite their relevance, a…
Photostability of gas- and solid-phase biomolecules within dense molecular clouds due to soft X-rays
S. Pilling, D. P. P. Andrade, E. M. do Nascimento +8
An experimental photochemistry study involving gas- and solid-phase amino acids (glycine, DL-valine, DL-proline) and nucleobases (adenine and uracil) under soft X-rays was performe…
Dissociation of the benzene molecule by UV and soft X-rays in circumstellar environment
H. M. Boechat-Roberty, R. Neves, S. Pilling +2
Benzene molecules, present in the proto-planetary nebula CRL 618, are ionized and dissociated by UV and X-ray photons originated from the hot central star and by its fast wind. Ion…
Survival of gas phase amino acids and nucleobases in space radiation conditions
S. Pilling, D. P. P. Andrade, R. B. de Castilho +6
We present experimental studies on the photoionization and photodissociation processes (photodestruction) of gaseous amino acids and nucleobases in interstellar and interplanetary…
