Protective Effects of Halite to Vacuum and Vacuum-Ultraviolet Radiation: A Potential Scenario During a Young Sun Superflare
Ximena C. Abrevaya, Douglas Galante, Paula M. Tribelli +16
Halite (NaCl mineral) has exhibited the potential to preserve microorganisms for millions of years on Earth. This mineral was also identified on Mars and in meteorites. In this stu…
Natural radioactive environments as sources of local disequilibrium for the emergence of life
Thiago Altair, Larissa M. Sartori, Fabio Rodrigues +2
Certain subterranean environments of Earth have naturally accumulated long-lived radionuclides, such as 238U, 232Th and 40K, near the presence of liquid water. In these natural rad…
Liquid Argon test of the ARAPUCA device
E. Segreto, A. A. Machado, L. Paulucci +11
The ARAPUCA is a novel concept for liquid argon scintillation light detection which has been proposed for the photon detection system of the Deep Underground Neutrino Experiment. T…
Propagation and energy deposition of cosmic rays' muons on terrestrial environments
Franciole Marinho, Laura Paulucci, Douglas Galante
Earth is constantly struck by radiation coming from the interstellar medium. The very low energy end of the spectrum is shielded by the geomagnetic field but charged particles with…
"Probing the limits of extremophilic life in extraterrestrial environment-simulated experiments"
Claudia Lage, Gabriel Dalmaso, Lia Teixeira +8
The results obtained in these experiments have revealed a remarkable resistance of extremophilic bacteria and archaea against different radiation sources (VUV, solar wind simulants…
Comparative Survival Analysis of Deinococcus Radiodurans and the Haloarchaea Natrialba Magadii and Haloferax Volcanii, Exposed to Vacuum Ultraviolet Irradiation
Ximena C. Abrevaya, Ivan G. Paulino-Lima, Douglas Galante +4
The haloarchaea Natrialba magadii and Haloferax volcanii, as well as the radiation-resistant bacterium Deinococcus radiodurans, were exposed to vacuum-UV (V-UV) radiation at the Br…
Effects of Gamma Ray Bursts in Earth Biosphere
Osmel Martin, Rolando Cardenas, Mayrene Guimaraes +3
We continue former work on the modeling of potential effects of Gamma Ray Bursts on Phanerozoic Earth. We focus on global biospheric effects of ozone depletion and show a first mod…
Short-term Effects of Gamma Ray Bursts on Earth
Osmel Martín, Douglas Galante, Rolando Cárdenas +1
The aim of the present work is to study the potential short-term atmospheric and biospheric influence of Gamma Ray Bursts on the Earth. We focus in the ultraviolet flash at the pla…
Biological Effects of Gamma-Ray Bursts: distances for severe damage on the biota
Douglas Galante, Jorge Ernesto Horvath
We present in this work a unified, quantitative synthesis of analytical and numerical calculations of the effects that could be caused on Earth by a Gamma-Ray Burst (GRB), consider…
