Analysis of the emission of very small dust particles from Spitzer spectro-imagery data using blind signal separation methods
O. Berne, C. Joblin, Y. Deville +6
This work was conducted as part of the SPECPDR program, dedicated to the study of very small particles and astrochemistry, in Photo-Dissociation Regions (PDRs). We present the anal…
Differential fast fixed-point algorithms for underdetermined instantaneous and convolutive partial blind source separation
J. Thomas, Y. Deville, Shahram Hosseini
This paper concerns underdetermined linear instantaneous and convolutive blind source separation (BSS), i.e., the case when the number of observed mixed signals is lower than the n…
Extended Red Emission and the evolution of carbonaceaous nanograins in NGC 7023
O. Berne, C. Joblin, M. Rapacioli +3
Extended Red Emission (ERE) was recently attributed to the photo-luminescence of either doubly ionized Polycyclic Aromatic Hydrocarbons (PAH), or charged PAH dimers. We anal…
Euclid. I. Overview of the Euclid mission
Euclid Collaboration, Y. Mellier, Abdurro'uf +1134
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…
