An extremely luminous panchromatic outburst from the nucleus of a distant galaxy
A. J. Levan, N. R. Tanvir, S. B. Cenko +58
Variable X-ray and gamma-ray emission is characteristic of the most extreme physical processes in the Universe, and studying the sources of these energetic photons has been a major…
The two states of Sgr A* in the near-infrared: bright episodic flares on top of low-level continuous variability
K. Dodds-Eden, S. Gillessen, T. K. Fritz +11
In this paper we examine properties of the variable source Sgr A* in the near-infrared (NIR) using a very extensive Ks-band data set from NACO/VLT observations taken 2004 to 2009.…
Correlated Fluctuations between Luminescence and Ionization in Liquid Xenon
E. Conti, R. DeVoe, G. Gratta +19
The ionization of liquefied noble gases by radiation is known to be accompanied by fluctuations much larger than predicted by Poisson statistics. We have studied the fluctuations o…
Next Generation Very Large Array Memo No. 5: Science Working Groups -- Project Overview
C. L. Carilli, M. McKinnon, J. Ott +17
We summarize the design, capabilities, and some of the priority science goals of a next generation Very Large Array (ngVLA). The ngVLA is an interferometric array with 10x larger e…
Supermassive Black Holes and the Evolution of Galaxies
D. Richstone, E. A. Ajhar, R. Bender +11
Black holes, an extreme consequence of the mathematics of General Relativity, have long been suspected of being the prime movers of quasars, which emit more energy than any other o…
Supernova OH (1720 MHz) Masers in Sgr A East, W28 and G359.1-0.5
F. Yusef-Zadeh, D. A. Roberts, G. Bower +1
A new class of OH (1720 MHz) masers unaccompanied by main-line transitions have recently been discovered (Frail, Goss and Slysh 1994). These masers lie at the interface between sup…
White Paper on East Asian Vision for mm/submm VLBI: Toward Black Hole Astrophysics down to Angular Resolution of 1~R
K. Asada, M. Kino, M. Honma +35
This White Paper details the intentions and plans of the East Asian Very Long Baseline Interferometry (VLBI) community for pushing the frontiers of millimeter/submillimeter VLBI. T…
Absolute Flux Density Calibration of the Greenland Telescope Data for Event Horizon Telescope Observations
J. Y. Koay, K. Asada, S. Matsushita +35
Starting from the observing campaign in April 2018, the Greenland Telescope (GLT) has been added as a new station of the Event Horizon Telescope (EHT) array. Visibilities on baseli…
