Panchromatic calibration of Ca II triplet luminosity dependence
(EDP Sciences, 2020-10)
The line strength of the near-infrared Ca II triplet (CaT) lines are a proxy for measuring metallicity from integrated and individual stellar spectra of bright red giant stars. In the latter case it is a mandatory step to ...
The antenna DSA 3 and its potential use for Radio Astronomy
(Asociacion Argentina de Astronomia, 2011-10)
The European Space Agency (ESA) will inaugurate its third Deep Space Antenna (DSA 3) by the end of 2012. DSA 3 will be located in Argentina near the city of Malarg"ue in the Mendoza province. While the instrument will ...
The Giant Radio Array for Neutrino Detection
(EDP Sciences, 2017)
The Giant Radio Array for Neutrino Detection (GRAND) is a planned arrayof ~2x10^{5} radio antennas deployed over ∼ 200 000 km^2 in a mountainous site. It aims primarly at detecting high-energy neutrinos via the observation ...
A new method to generate dust with astrophysical properties
(Iop Publishing, 2011-05-25)
To model the size distribution and composition of interstellar and interplanetary dust grains, and their effect on a wide range of phenomena, it is vital to understand the mechanism of dust-shock interaction. We demonstrate ...
Mapping low- and high-density clouds in astrophysical nebulae by imaging forbidden line emission
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Emission line ratios have been essential for determining physical parameters such as gas temperature and density in astrophysical gaseous nebulae. With the advent of panoramic spectroscopic devices, images of regions with ...
Radiolysis and sputtering of carbon dioxide ice induced by swift Ti, Ni, and Xe ions
(2015)
Solid carbon dioxide (CO2) is found in several bodies of the solar system, the interstellar medium (ISM) and young stellar objects, where it is exposed to cosmic and stellar wind radiation. Here, the chemical and physical ...
Monte Carlo design studies for the Cherenkov Telescope Array
(Elsevier Science, 2013-03)
The Cherenkov Telescopes Array (CTA) is planned as the future instrument for very-high-energy (VHE) gamma-ray astronomy with a wide energy range of four orders of magnitude and an improvement in sensitivity compared to ...
A combined maximum-likelihood analysis of the high-energy astrophysical neutrino flux measured with IceCube
(IOP Publishing, 2015-08-13)
Evidence for an extraterrestrial flux of high-energy neutrinos has now been found in multiple searches with the IceCube detector. The first solid evidence was provided by a search for neutrino events with deposited energies ...
