Event-horizon-scale structure in the supermassive black hole candidate at the Galactic Centre
TLDR
Observations at a wavelength of 1.3 mm set a size of microarcseconds on the intrinsic diameter of Sagittarius A*, suggesting that the bulk of Sgr A* emission may not be centred on the black hole, but arises in the surrounding accretion flow.
A fast radio burst localized to a massive galaxy
TLDR
Use of a specially built radio interferometer shows that a non-repeating fast radio burst is localized to a few-arcsecond region containing a single massive galaxy, and is perhaps derived from an old stellar population.
First M87 Event Horizon Telescope Results. I. The Shadow of the Supermassive Black Hole
When surrounded by a transparent emission region, black holes are expected to reveal a dark shadow caused by gravitational light bending and photon capture at the event horizon. To image and study…
1.3 mm Wavelength VLBI of Sagittarius A*: Detection of Time-variable Emission on Event Horizon Scales
Sagittarius A*, the ~4 × 10^6 M_⊙ black hole candidate at the Galactic center, can be studied on Schwarzschild radius scales with (sub)millimeter wavelength very long baseline interferometry (VLBI).…
DYNAMICALLY DRIVEN EVOLUTION OF THE INTERSTELLAR MEDIUM IN M51
Massive star formation occurs in giant molecular clouds (GMCs); an understanding of the evolution of GMCs is a prerequisite to develop theories of star formation and galaxy evolution. We report the…
Interferometric Observations of 1.4 Millimeter Continuum Sources
A set of 1.4-mm continuum measurements for a sample of 15 Galactic and extragalactic sources obtained with a millimeter-wave interferometer are presented. Maps at 3 arcsec resolution reveal compact…
TRACING THE BIPOLAR OUTFLOW FROM ORION SOURCE I
Using CARMA, we imaged the 87 GHz SiO v = 0 J = 2-1 line toward Orion-KL with 045 angular resolution. The maps indicate that radio source I drives a bipolar outflow into the surrounding molecular…
THE OWENS VALLEY MILLIMETER ARRAY
The telescopes and signal processing systems of the Owens Valley Millimeter Array are considered, and improvements in the sensitivity and stability of the instrument are characterized. The instrument…
LoCuSS: THE SUNYAEV–ZEL’DOVICH EFFECT AND WEAK-LENSING MASS SCALING RELATION
We present the first weak-lensing-based scaling relation between galaxy cluster mass, M_WL, and integrated Compton parameter Y_sph. Observations of 18 galaxy clusters at z ≃ 0.2 were obtained with…
A λ = 1.3 Millimeter Aperture Synthesis Molecular Line Survey of Orion Kleinmann-Low
We present a 1".3 spatial resolution interferometric spectral line survey of the core of the Orion molecular cloud, obtained with the OVRO millimeter array. Covering 4 GHz bandwidth in total, the…
