The Institute of Space Science was represented at the LISA Consortium Meeting – LISA Phase A Activities, which took place between January 29th – 30th, 2018, at the Max-Planck Institute for Gravitational Physics (Albert Einstein Institute), in Hannover, Germany, by Dr. Ion Sorin ZGURĂ, Director of the Institute of Space Science, Dr. Laurențiu Ioan CARAMETE, Head of the Cosmology and AstroParticle Physics Group and Dr. Eugeniu Mihnea Popescu, Head of the High Energy Astrophysics and Advanced Technology Group. The status of the future LISA space mission, which is an L-type (Large) mission of the European Space Agency, was presented, as well as the foreseen contributions of each entity in the consortium.

The Laser Interferometer Space Antenna (LISA) will be the first space-based gravitational wave observatory and it will consist of 3 satellites joined by laser interferometers, placed in a triangle, at a distance of 2.5 million kilometers that will follow the Earth in its orbit around the Sun for an in-depth study of the Gravitational Universe. The satellites will have similar characteristics with the LISA Pathfinder mission, which flew successfully in December 2015 and has tested the most important technical components.

The Institute of Space Science will contribute to the LISA space mission with the Constellation Acquisition Sensor (CAS) system, which will verify the alignment of the 3 satellites, ensuring the acquisition of the laser signal on the interferometric detectors. Together with the Coarse Star Tracker (STR) system, CAS will check the visualization of the laser signal at the scanning maneuver stage. This contribution is fully supported by the Romanian Space Agency (by the programs “Romanian Incentive Scheme”, PRODEX and national programs) and is in excellent agreement with the Institute of Space Science strategy, as well as with the national strategy of research and development in Romania.

At the express request of the LISA Consortium, the Romanian Space Agency (ROSA) appointed as representative in the “LISA National Agency Board” (which has representatives from each national space agency in the consortium) Dr. Marius-Ioan Piso, president and CEO of the Romanian Space Agency, who is recognized by the scientific community as one of the main initiators of gravitational radiation research since the ’80s. Also, Dr. Ion Sorin ZGURĂ, Director of the Institute of Space Science was appointed as delegate member in the LISA National Agency Board.

LISA space mission is proposed by an international consortium made by researchers from Germany, Italy, Switzerland, United Kingdom, Spain, Denmark, Holland, Romania, Belgium, Portugal, Sweden, Hungary and United States of America. The launch of LISA is foreseen in 2034, with a lifetime of the mission for 4 years and the possibility of an extension up to 10 years.

NASA reveals the existence of an exoplanetary system at 40 light years away from Earth

On February 22nd, 2017, through a press release, NASA reveals a historic discovery concerning the existence of new exoplanetary system, called TRAPPIST-1, which hosts seven planets, comparable in size and mass with Earth; three of them being located in the habitable zone, the most likely to have liquid water. The super-cool dwarf star, located at about 40 light years away from Earth, is being named after the TRAPPIST mission – Transiting Planets and Planetesimals Small Telescopes.

”One light year means about nine trillion kilometers, i.e at one milliard add three more zeroes. At the moment we cannot perceive yet to cover such a distance with human capabilities. Perhaps, it is necessary a paradigm shift, a change of perception, which will allow us, hopefully in a near future, to see how we could access these stars”, says President of the Romanian Space Agency (ROSA), Dr. Marius-Ioan Piso, in an interview accorded at Radio France International (RFI).

The observations began at the end of 2015, when a team of astronomers from University of Liege, Belgium, decoded the data acquired with the Liege telescope TRAPPIST-Sud, located in Chile. Further ongoing observations have implied more telescopes on-ground (TRAPPIST-Nord in Morocco, UK Infrared Telescope – UKIRT in Hawaii, William Herschel and Liverpool telescopes in La Palma, and the South African Astronomical Observatory telescope) and the NASA’s Spitzer space telescope.

In order to detail the atmospheric composition, or the structure of the rock of those planets, we may need perhaps a decade from now on”, says scientific researcher at the Institute of Space Science (ISS), Dr. Gina Isar, in an interview accorded at Antena 1 Observator TV.

However, NASA has made the reveal that seven planets revolve around TRAPPIST-1, through long and dedicated observations of better precision with the Spitzer space telescope. The remarkable results were recently published in Nature, which conclude that: “The TRAPPIST-1 system represents a unique opportunity to thoroughly characterize temperature Earth-like planets that are orbiting a much cooler and smaller star than the Sun” [Gillon, M. et al. Nature, 2017].

The TRAPPIST telescopes are part of a wider project called SPECULOOS – Search for habitable Planets EClipsing Ultra-cOOl Stars, which aims to detect more systems of this type, with four new telescopes in Chile.

Further observations will continue with new performant telescopes, both on ground and in space.

INA – An interactive software tool for the statistical analysis of time series with application to space plasma turbulence

ina_diagram
The diagram of INA and the schematic illustration of its main functionalities.

INA (Integrated Nonlinear Analysis) is an interactive software product designed to analyze satellite data with advanced nonlinear methods adapted to space plasma turbulence research. The software is developed in the framework of the European Community’s Seventh Framework Programme project STORM (Solar system plasma Turbulence: Observations, inteRmittency and Multifractals) where ISS had a significant contribution. The main developers are Dr. Costel Munteanu (scientist at the Institute of Space Science – ISS), Dr. Marius Echim (senior scientist at ISS and also at the Belgian Institute for Space Aeronomy (BISA), Brussels) and Dr. Peter Kovacs (senior scientist at the Geological and Geophysical Institute of Hungary, Budapest).

INA is publicly available from the website of the project (http://www.storm-fp7.eu) as an executable file to be run under Windows or Linux operating systems. The download page is available after registration by email to marius.echim@oma.be.

The software is written in MATLAB (version 2015a), but it can also be used independently by installing a MATLAB compiler, which can be downloaded freely from here. Through an intuitive graphical user interface (GUI), INA provides a complete statistical analysis of a time series and provides various methods: descriptive analysis, power spectral density (PSD), spectrogram analysis, analysis of probability distribution functions (PDF) of fluctuations, wavelet analysis, structure function analysis (SF), and multifractal analysis using the rank ordered multifractal analysis (ROMA).

INA is optimized for the analysis of magnetic field and plasma data provided by Venus Express, Cluster and Ulysses satellites, but has also adequate modules for reading and analyzing other data types.

For more information about INA, the software developers can be contacted directly by email: Dr. Marius Echim <marius.echim [at] oma [dot] be>, Dr. Costel Munteanu <costelm [at] spacescience [dot] ro>, Dr. Peter Kovacs <kovacs [dot] peter [at] mfgi [dot] hu>.

Scientists have developed a technique to use quasars – powerful sources driven by supermassive black holes at the centre of galaxies – to study the Universe’s history and composition. To demonstrate the new method, based on a relation between a quasar’s luminosity at X-ray and ultraviolet wavelengths, they made extensive use of data from XMM-Newton X-ray observatory of the European Space Agency (ESA). This approach promises to become an important tool to constrain the properties of our Universe.

The Large Hadron Collider (LHC) has successfully completed its planned proton run for 2015, delivering the equivalent of about 400 trillion (1012) proton-proton collisions to both the ATLAS (A Toroidal LHC ApparatuS) and CMS (Compact Muon Solenoid) experiments. LHCb (Large Hadron Collider beauty) and ALICE (A Large Ion Collider Experiment) have also enjoyed successful data taking at lower collision rates.
