Phase Closure Image Reconstruction for Future VLTI Instrumentation
Mercedes E. Filho, Stephanie Renard, Paulo Garcia +21
Classically, optical and near-infrared interferometry have relied on closure phase techniques to produce images. Such techniques allow us to achieve modest dynamic ranges. In order…
Phase Referencing in Optical Interferometry
Mercedes E. Filho, Paulo Garcia, Gilles Duvert +20
One of the aims of next generation optical interferometric instrumentation is to be able to make use of information contained in the visibility phase to construct high dynamic rang…
Atmospheric dynamics of red supergiant stars and applications to Interferometry
A. Chiavassa, B. Plez, E. Josselin +1
We have written a 3D radiative transfer code that computes emerging spectra and intensity maps. We derive from radiative hydrodynamic (RHD) simulations of RSG stars carried out wit…
Atmospheric dynamics of red supergiant stars and Interferometry
A. Chiavassa
We developed a 3D pure LTE radiative transfer code to derive observables expected for RSGs, with emphasis on small scale structures, from radiative-hydrodynamic (RHD) simulations o…
Milli-arcsecond astrophysics with VSI, the VLTI spectro-imager in the ELT era
F. Malbet, D. Buscher, G. Weigelt +49
Nowadays, compact sources like surfaces of nearby stars, circumstellar environments of stars from early stages to the most evolved ones and surroundings of active galactic nuclei c…
Detection and imaging of atmospheric radio flashes from cosmic ray air showers
H. Falcke, W. D. Apel, A. F. Badea
The nature of ultrahigh-energy cosmic rays (UHECRs) at energies >10^20 eV remains a mystery. They are likely to be of extragalactic origin, but should be absorbed within ~50 Mpc th…
