A ring-like accretion structure in M87 connecting its black hole and jet
Ru-Sen Lu, Keiichi Asada, Thomas P. Krichbaum +118
The nearby radio galaxy M87 is a prime target for studying black hole accretion and jet formation^{1,2}. Event Horizon Telescope observations of M87 in 2017, at a wavelength of 1.3…
An 86-GHz search for Pulsars in the Galactic Center with the Atacama Large Millimeter/submillimeter Array
Kuo Liu, Gregory Desvignes, Ralph P. Eatough +24
We report on the first pulsar and transient survey of the Galactic Center (GC) with the Atacama Large Millimeter/submillimeter Array (ALMA). The observations were conducted during…
Persistent Non-Gaussian Structure in the Image of Sagittarius A* at 86 GHz
S. Issaoun, M. D. Johnson, L. Blackburn +26
Observations of the Galactic Center supermassive black hole Sagittarius A* (Sgr A*) with very long baseline interferometry (VLBI) are affected by interstellar scattering along our…
Revealing HI gas in emission and absorption on pc to kpc scales in a galaxy at z ~ 0.017
N. Gupta, R. Srianand, J. S. Farnes +6
We present a detailed study of the quasar-galaxy pair: J1243+4043 - UGC07904. The sight line of the background quasar ( = 1.5266) passes through a region of the galaxy (=…
High-Resolution Images of Diffuse Neutral Clouds in the Milky Way. I. Observations, Imaging, and Basic Cloud Properties
Yurii Pidopryhora, Felix J. Lockman, John M. Dickey +1
A set of diffuse interstellar clouds in the inner Galaxy within a few hundred pc of the Galactic plane has been observed at an angular resolution of ~1 arcmin combining data from t…
The SFXC software correlator for Very Long Baseline Interferometry: Algorithms and Implementation
A. Keimpema, M. M. Kettenis, S. V. Pogrebenko +13
In this paper a description is given of the SFXC software correlator, developed and maintained at the Joint Institute for VLBI in Europe (JIVE). The software is designed to run on…
A mildly relativistic radio jet from the otherwise normal Type Ic Supernova 2007gr
Z. Paragi, G. B. Taylor, C. Kouveliotou +11
The class of type Ic supernovae have drawn increasing attention since 1998 owing to their sparse association (only four so far) with long duration gamma-ray bursts. Although both p…
