Gravitational Waves detection and spectroscopy with a Double-slit Quantum Eraser

Clovis Jacinto de Matos, Fabrizio Tamburini, Josep Maria Perdigues Armengol +1

We propose the use of heralded photons to detect Gravitational Waves (GWs). Heralded photons are those photons that, produced during a parametric downconversion process, are "label…

New Abundances for Old Stars - Atomic Diffusion at Work in NGC 6397

A. J. Korn, F. Grundahl, O. Richard +5

A homogeneous spectroscopic analysis of unevolved and evolved stars in the metal-poor globular cluster NGC 6397 with FLAMES-UVES reveals systematic trends of stellar surface abunda…

A probable stellar solution to the cosmological lithium discrepancy

A. J. Korn, F. Grundahl, O. Richard +5

The measurement of the cosmic microwave background has strongly constrained the cosmological parameters of the Universe. When the measured density of baryons (ordinary matter) is c…

The substellar population of the young cluster lambda Orionis

David Barrado y Navascues, J. R. Stauffer, J. Bouvier +2

By collecting optical and infrared photometry and low resolution spectroscopy, we have identified a large number of low mass stars and brown dwarf candidates belonging to the young…

CIV Absorbers in z>4 Quasars: Tracing Early Galactic Halos Evolution

Celine Peroux, Patrick Petitjean, Bastien Aracil +2

We use 29 z>4 quasar spectra to build a homogeneous sample of high-redshift CIV absorbers. We use these data to calculate the number density, n(z), of W_rest(CIV)>0.30 A CIV double…

Misleading results from low-resolution spectroscopy: from galaxy interstellar medium chemistry to cosmic star formation density

Y. C. Liang, F. Hammer, H. Flores +2

Low resolution spectroscopy (R=150) from the Canada-France-Redshift Survey (CFRS) had revealed intriguing properties for low redshift galaxies (z<=0.3): nearly half of their spectr…
