GOODS-HERSCHEL: evidence for a UV extinction bump in galaxies at z > 1

V. Buat, E. Giovannoli, S. Heinis +16

Dust attenuation curves in external galaxies are useful to study their dust properties as well as to interpret their intrinsic spectral energy distributions. In particular the pres…

Studying the spatially resolved Schmidt-Kennicutt law in interacting galaxies: the case of Arp 158

Médéric Boquien, Ute Lisenfeld, Pierre-Alain Duc +4

Recent studies have shown that star formation in mergers does not seem to follow the same Schmidt-Kennicutt (KS) relation as in spiral disks, presenting a higher star formation rat…
