TL;DR: In this article, the authors presented the first time the multi-wavelength AGILE, Swift, INTEGRAL, and GASP-WEBT data collected in order to explain the extraordinary?-ray flare of 3C 454.3 which occurred in 2010 November.
Journal ArticleDOI
On the Diversity of Asymmetries in Gapped Protoplanetary Disks
Nienke van der Marel,T. Birnstiel,Antonio Garufi,Enrico Ragusa,Valentin Christiaens,Daniel J. Price,Steph Sallum,Dhruv Muley,Logan Francis,Ruobing Dong +9 more
TL;DR: In this article, the authors compare the azimuthal extents of the dust continuum profiles with the local gas surface density in each disk, and find that the asymmetries correspond to higher Stokes numbers or low gas surface densities.
