Mesure de la cinématique interne des galaxies en spectroscopie sans fente

Autor: Outini, Mehdi

La spectroscopie sans fente a longtemps été considérée comme une technique compliquée de part ses effets d’auto- et d’inter-contamination. Toutefois, depuis l’ère des instruments du Télescope Spatial Hubble qui offrent un bruit de fond f

The accelerating expansion of the universe is one of the main topics of modern cosmology. It may stem from a new component, so-called dark energy, which would make up 70% of the energy content of the universe. To study its nature through its equation

A high-resolution spectrograph for the 3.6-m Devasthal Optical Telescope of ARIES

Autor: Pandey, Jeewan Chandra, Pant, Jayshreekar, Joshi, Yogesh Chandra

A high-resolution spectrograph for the 3.6-m Devasthal Optical Telescope (DOT) of Aryabhatta Reearch Institute of Observational Sciences (ARIES; Nainital, India) is envisaged to achieve the various science goals. The spectrograph will have two modes

We present observations with the planet finder SPHERE of a selected sample of the most promising radial velocity (RV) companions for high-contrast imaging. Using a Monte Carlo simulation to explore all the possible inclinations of the orbit of wide R
