Mobile applications and Virtual Observatory
Schaaff, A.; Jagade, S.
Within a few years, smartphones and Internet tablets have become the devices to access Web or standalone applications from everywhere, with a rapid development of the bandwidth of the mobile networks (e.g. 4G). Internet tablets are used to take notes during meetings or conferences, to read scientific papers in public transportation, etc. A smartph…
Spectroscopic analysis in the virtual observatory environment with SPLAT-VO
Jenness, T.; Draper, P. W.; Škoda, P. +2 more
SPLAT-VO is a powerful graphical tool for displaying, comparing, modifying and analysing astronomical spectra, as well as searching and retrieving spectra from services around the world using Virtual Observatory (VO) protocols and services. The development of SPLAT-VO started in 1999, as part of the Starlink StarJava initiative, sometime before th…
Simulated measurements of 67P/Churyumov-Gerasimenko dust coma at 3 AU by the Rosetta GIADA instrument using the GIPSI tool
Fulle, M.; Altobelli, N.; Della Corte, V. +7 more
GIADA (Grain Impact Analyzer and Dust Accumulator) is an in situ instrument, on board the Rosetta spacecraft, designed to measure the dynamical properties of the dust grains emitted by the comet 67P/Churiumov-Gerasimenko (hereafter 67P/C-G). It consists of three subsystems able to measure the mass and speed of single dust grain and dust mass flux.…
Iris: An extensible application for building and analyzing spectral energy distributions
Pevunova, O.; Thomas, B.; D'Abrusco, R. +11 more
Iris is an extensible application that provides astronomers with a user-friendly interface capable of ingesting broad-band data from many different sources in order to build, explore, and model spectral energy distributions (SEDs). Iris takes advantage of the standards defined by the International Virtual Observatory Alliance, but hides the techni…
Irregular time series in astronomy and the use of the Lomb-Scargle periodogram
Andreani, P.; Vio, R.; Diaz-Trigo, M.
Detection of a signal hidden by noise within a time series is an important problem in many astronomical searches, i.e. for light curves containing the contributions of periodic/semi-periodic components due to rotating objects and all other astrophysical time-dependent phenomena. One of the most popular tools for use in such studies is the periodog…
GOLIA: An INTEGRAL archive at INAF-IASF Milano
Götz, D.; Mereghetti, S.; Sidoli, L. +5 more
We present the archive of the INTEGRAL data developed and maintained at INAF-IASF Milano. The archive comprises all the public data currently available (revolutions 0026-1079, i.e., December 2002-August 2011). INTEGRAL data are downloaded from the ISDC Data Centre for Astrophysics, Geneva, on a regular basis as they become public and a customized …
