This seminar talk will give a short overview of the current status of the field of Astroparticle Physics. The subject includes a great variety of instruments...
Inverse problem approach in adaptive optics for the European-ELT
The ambitious astrophysical objectives of the Extremely Large Telescopes (ELTs) will be achievable only with innovative Adaptive Optics (AO) systems to correct...
Deep learning is rapidly becoming a standard tool in many scientific disciplines including astronomy. I will review recent and on-going work on several...
Ionization of the diffuse gas in galaxies: hot low-mass evolved stars at work
We revisit the question of the ionization of the diffuse medium in late type galaxies, by studying NGC 891, the prototype of edge-on spiral galaxies. The most...
Is Dark Matter the most valid explanation for the mass which is apparently missing in the Universe?
Two main families of models explain that, at least in appearance, something like 90% of the mass of the Universe is still undetected. One (supported by an...
Is star formation a stochastic or a regulated process?
The stellar initial mass function (IMF) is usually assumed to be a probability density distribution function. Recent data appear to question this interpretation...
In comparison with Solar twins in the Solar neighborhood the Sun has been found to be somewhat poor in refractory elements relative to volatiles. Why is that...
