A search for hypercompact HII regions in the Galactic Plane
(2019-01-11)
We have carried out the largest and most unbiased search for hypercompact (HC) H II regions. Our method combines four interferometric radio continuum surveys (THOR, CORNISH, MAGPIS, and White2005) with far-infrared and ...
The relationship between dust and [C I] at z = 1 and beyond
(2019-01-01)
Measuring molecular gas mass is vital for understanding the evolution of galaxies at high redshifts (z ≳ 1). Most measurements rely on CO as a tracer, but dependencies on metallicity, dynamics, and surface density lead to ...
How frequent are close supermassive binary black holes in powerful jet sources?
(2019-01-01)
Supermassive black hole binariesmay be detectable by an upcoming suite of gravitationalwave experiments. Their binary nature can also be revealed by radio jets via a short-period precession driven by the orbital motion as ...
