Jordi Torra i Roca, Barcelona, 23/04/1949 – 26/02/2019

Ph.D. in Physics by the Universitat de Barcelona (1984) and Professor in the Department of Quantum Physics and Astrophysics in the same University, he focused his research career in the study of the structure, formation and evolution of our Galaxy, the Milky Way. He was one of the pioneers at European level in the development of the field of Astrometry from Space. In the 80s he accepted the challenge to lead the Spanish participation in the European Space Agency’s Hipparcos mission and, as a result from this work, Spain is fully participating in the Gaia mission, launched in 2013 and...

Gaia DR2 bulk catalogue available in FAPEC format

The Gaia group at the Universitat de Barcelona (IEEC – ICCUB), in cooperation with DAPCOM Data Services S.L. (a technological spin-off company of the UPC and the UB), has published an alternative copy of the bulk data files from Gaia DR2 – the second data release from Gaia. Gaia DR2 was published on 25 April 2018. Besides the on-line catalogue, bulk CSV files were also made available for download – an interesting option for exhaustive analyses. Such files are officially offered in “csv.gz” format, that is, compressed with the widely known gzip compressor. On 6...

Gaia detects a shake in the Milky Way

Image: The spiral shape of fig 1c of our article appears inside an old watch symbolising the fact that these data has allowed us to date back the perturbation that shook the Milky Way disk. This figure shows how from the new obtained Gaia data we can know more about the past of the Galaxy.   Credit: Edmon de Haro/iStock.   Researchers of the UB and the University of Groningen lead one of the first big discoveries from the Gaia Mission, published in Nature A team led by researchers from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB, UB-IEEC) and the...

Gaia’s snapshot of another galaxy (ESA, 20 April 2017)

Gaia’s snapshot of another galaxy Link: http://sci.esa.int/gaia/59023-gaia-s-snapshot-of-another-galaxy/ While compiling an unprecedented census of one billion stars in our Galaxy, ESA’s Gaia mission is also surveying stars beyond our Milky Way. A new image of M33, also known as the Triangulum galaxy, shows tens of thousands of stars detected by Gaia, including a small stellar census in its star-forming region NGC 604. This is a striking example of the mission’s potential to detect and characterise stars in nearby galaxies. Gaia’s view of the M33 galaxy. Credit:...
