Measurements and modelisation of shadowing cross-correlations between two base-stations
Karim Zayana, Bertrand Guisnet
Measurements in macrodiversity situations have been performed. Crosscorrelation of shadowing terms between two basestations and a mobile have been computed. It results that high cr…
Mesure simultan{é}e des r{é}ponses impulsionnelles en macrodiversit{é}
Karim Zayana, Daniel Duponteil
Macroscopic diversity in radiomobile systems is a technique in which the terminal is in parallel connection with two base stations. It is a fundamental element in the operation of…
Le Soleil se lèvera-t-il demain ?
Karim Zayana, Olivier Rioul
Should we live every day as if it were our last? This question is legitimate when we know that Pierre-Simon de Laplace, in 1814, estimated the probability that the Sun would rise a…
All of Monty
Karim Zayana, Ivan Boyer
Everything has already been said about the Monty Hall problem, to the point of attracting attention of the high school mathematics program. The purpose of this text is therefore no…
Ending the prompt phase in photospheric models of gamma-ray bursts
Filip Alamaa, Frédéric Daigne, Robert Mochkovitch
The early steep decay, a rapid decrease in X-ray flux as a function of time following the prompt emission, is a robust feature seen in almost all gamma-ray bursts with early enough…
JWST MIRI flight performance: Detector Effects and Data Reduction Algorithms
Jane Morrison, Daniel Dicken, Ioannis Argyriou +21
The detectors in the Mid-Infrared Instrument (MIRI) of the James Webb Space Telescope (JWST) are arsenic-21 doped silicon impurity band conduction (Si:As IBC) devices and are direc…
Infomathic
Karim Zayana, Régis Queruel, Pierre Michalak
Since its existence, the computer tool has often supported mathematicians, whether it is to implement an approximation method (numerical calculation of a root, of an integral, ...)…
Shock excitation of H in the James Webb Space Telescope era
L. E. Kristensen, B. Godard, P. Guillard +2
(Abridged) H2 is the most abundant molecule in the Universe. Thanks to its widely spaced energy levels, it predominantly lights up in warm gas, T > 100 K, such as shocked regions,…
A cosmic stream of atomic carbon gas connected to a massive radio galaxy at redshift 3.8
Bjorn H. C. Emonts, Matthew D. Lehnert, Ilsang Yoon +7
The growth of galaxies in the early Universe is driven by accretion of circum- and inter-galactic gas. Simulations predict that steady streams of cold gas penetrate the dark matter…
Observations of the Planetary Nebula SMP LMC 058 with the JWST MIRI Medium Resolution Spectrometer
O. C. Jones, J. Álvarez-Márquez, G. C. Sloan +21
During the commissioning of {\em JWST}, the Medium-Resolution Spectrometer (MRS) on the Mid-Infrared Instrument (MIRI) observed the planetary nebula SMP LMC 058 in the Large Magell…
Multi-phase gas interactions on subarcsec scales in the shocked IGM of Stephan's Quintet with JWST and ALMA
P. N. Appleton, P. Guillard, B. Emonts +12
We combine JWST and HST imaging with ALMA~CO(2-1) spectroscopy to study the highly turbulent multi-phase intergalactic medium (IGM) in Stephan's Quintet on 25-150 pc scales. Previo…
