Detection of intrinsic source structure at ~3 Schwarzschild radii with Millimeter-VLBI observations of SAGITTARIUS A*
Ru-Sen Lu, Thomas P. Krichbaum, Alan L. Roy +53
We report results from very long baseline interferometric (VLBI) observations of the supermassive black hole in the Galactic center, Sgr A*, at 1.3 mm (230 GHz). The observations w…
A Keplerian disk around Orion Source I, a ~15 Msun YSO
Adam Ginsburg, John Bally, Ciriaco Goddi +2
We report ALMA long-baseline observations of Orion Source I (SrcI) with resolution 0.03-0.06" (12-24 AU) at 1.3 and 3.2 mm. We detect both continuum and spectral line emission from…
The First Detection of Neutral Hydrogen in Emission in a Strong Spiral Lens
Andrew Lipnicky, Sukanya Chakrabarti, Melvyn C. H. Wright +7
We report HI observations of eight spiral galaxies that are strongly lensing background sources. Our targets were selected from the Sloan WFC (Wide Field Camera) Edge-on Late-type…
