Press releases
- Ils réinventent la roue pour une mission spatiale
UNIGE Press Release, 29 October 2013
UNIGE has successfully completed its hardware activities for ASTRO-H, and the filter wheel has been delivered to SRON.
- Les amas de galaxies appelés à témoigner à propos de l’énergie sombre et de la matière noire
UNIGE Press Release, 13 January 2013
The baryonic mass fraction of 18 clusters is estimated from X-ray and Sunyaev-Zeldovich observations, showing that cool-core clusters are unbiased cosmological probes.
- Dark and bright: ESA chooses next two science missions
Un satellite pour traquer l'énergie sombre de l'Univers
ESA and UNIGE Press Release, 4 October 2011
ESA has selected Euclid as the Cosmic Vision M2 mission.
- ESA spacecraft reveal new anatomy around a black hole
ESA Press Release, 29 September 2011
A team led by J. Kaastra performed an unprecedented monitoring campaign on an AGN, MRK 509, using ESA's XMM-Newton and Integral spacecrafts. This led to the publication of several papers in A&A related to the absorber properties and the emission mechanisms in this object. More papers are in preparation.
- INTEGRAL observations suggest unified model for AGN requires a rethink
ESA Press Release, 2 August 2011
A study (Ricci et al. 2011) of stacked AGN INTEGRAL spectra revealed suprising properties among the most absorbed objects.
- New Light on Dark Energy
ESO Press Release 04/08, 30 January 2008
The Vimos-VLT Deep Survey led to a Nature paper (Guzzo et al. 2008) which showed that large-area spectroscopic surveys can constrain the cosmological parameters and the nature of gravity through the analysis of redshift distortions in the radial projection of the correlation function.
- X-rays betray giant particle accelerator in the sky
Un accélérateur de particules au ciel - Des astronomes de l'UNIGE traquent des rayons X à haute énergie
ESA and UNIGE Press Release, 24 January 2008
An INTEGRAL study of the Ophiuchus cluster (Eckert et al. 2008) showed for the first time convincing existence of non-thermal emission in the hard X-rays, meaning that these objects can be the site of particle acceleration
- Do Galaxies Follow Darwinian Evolution?
ESO Press release 45/06, 6 December 2006
The VVDS has shown the influence of environment on the evolution of galaxies. In particular, the color-density relation was markedly different 7 billion years ago, showing the importance of the initial conditions on the galaxy properties.
- Integral catches a new erupting black hole
ESA Press Release, 27 November 2006
- A Cosmic Baby-Boom
ESO Press Release 24/05 as well as CNRS and INAF, 22 September 2005
- New distant comet headed for bright encounter
ESO Press Release 10/95, 25 August 1995
