Myers, Ryan Hickox Abstract: Previous studies measuring the clustering of submillimeter galaxies (SMGs) have based their measurements on single-dish detected sources, finding evidence for strong clustering. However, ALMA has revealed that, due to the coarse angular resolution of these instruments, single-dish sources can be comprised of multiple sources. This implies that the clustering inferred from single-dish surveys may b… ApJ Eu

Tobin, Sam Federman, S. Thomas Megeath, Leslie W. Looney Abstract: The prevalence of substructures in ∼1−10 Myr old protoplanetary disks, which are often linked to planet formation, has raised the question of how early such features form, and as a corollary, how early planet formation begins. Here we present observations of seven protostellar disks (aged ∼0.1−1 Myr) from the VLA/ALMA Nascent Disk and Multiplicity Survey of Orion Protostars Submitted 1 October, 2020; originally announced October 2020.
