Calibrating the clock of JWST

A. W. Shaw, D. L. Kaplan, P. Gandhi +19

JWST, despite not being designed to observe astrophysical phenomena that vary on rapid time scales, can be an unparalleled tool for such studies. If timing systematics can be contr…

Links Between Optical and X-ray Light in Scorpius X-1

Alexander B. Igl, Robert I. Hynes, Christopher T. Britt +2

We observed the low-mass X-ray binary Sco X-1 for 12 nights simultaneously using the Rossi X-Ray Timing Explorer and the Otto Struve Telescope at McDonald Observatory at 1 second t…

Dynamical Modeling of CXOGBS J175553.2-281633: A 10 Hour Long Orbital Period Cataclysmic Variable

Sebastian Gomez, Manuel A. P. Torres, Peter G. Jonker +8

We present modeling of the long-term optical light curve and radial velocity curve of the binary stellar system CXOGBS J175553.2-281633, first detected in X-rays in the \textit{Cha…

Optical and X-ray Correlations During the 2015 Outburst of the Black Hole V404 Cyg

R. I. Hynes, E. L. Robinson, D. M. Terndrup +5

We present a serendipitous multiwavelength campaign of optical photometry simultaneous with Integral X-ray monitoring of the 2015 outburst of the black hole V404 Cyg. Large amplitu…

Simultaneous multiwavelength observations of V404 Cygni during its 2015 June outburst decay strengthen the case for an extremely energetic jet-base

Dipankar Maitra, John F. Scarpaci, Victoria Grinberg +4

We present results of multiband optical photometry of the black hole X-ray binary system V404 Cygni obtained using Wheaton College Observatory's 0.3m telescope, along with strictly…

An elevation of 0.1 light-seconds for the optical jet base in an accreting Galactic black hole system

Poshak Gandhi, Matteo Bachetti, Vik S. Dhillon +25

Relativistic plasma jets are observed in many accreting black holes. According to theory, coiled magnetic fields close to the black hole accelerate and collimate the plasma, leadin…
