A Cut-Free Sequent Calculus for Defeasible Erotetic Inferences
Jared Millson
In recent years, the effort to formalize erotetic inferences---i.e., inferences to and from questions---has become a central concern for those working in erotetic logic. However, f…
Discovery of 14NH3 (2,2) maser emission in Sgr B2-Main
E. A. C. Mills, A. Ginsburg, A. R. Clements +7
We report the discovery of the first 14NH3 (2,2) maser, seen in the Sgr B2 Main star forming region near the center of the Milky Way, using data from the Very Large Array radio tel…
Flux Density Variations at 3.6 cm in the Massive Star-Forming Region W49A
C. G. De Pree, R. Galván-Madrid, W. M. Goss +8
A number of ultracompact H II regions in Galactic star forming environments have been observed to vary significantly in radio flux density on timescales of 10-20 years. Theory pred…
Distributed star formation throughout the Galactic Center cloud Sgr B2
A. G. Ginsburg, John Bally, Ashley Barnes +23
We report ALMA observations with resolution " at 3 mm of the extended Sgr B2 cloud in the Central Molecular Zone (CMZ). We detect 271 compact sources, most of which are…
