We study the color structure of disk galaxies in the Groth strip at redshifts 0.1 z 1.2. Our aim is to test formation models in which bulges form before/after...

Ephemeral magnetic emergence has been detected in a decaying β region observed in December 2001 simultaneously with the DOT and THEMIS. We present here the main...

Analysis of the Hanle effect in solar molecular lines allows us to obtain empirical information on unresolved, tangled magnetic fields at subresolution scales...
