T Pyxidis: Death by a Thousand Novae
Joseph Patterson, Arto Oksanen, Jonathan Kemp +14
We report a 20-year campaign to track the 1.8 hour photometric wave in the recurrent nova T Pyxidis, using the global telescope network of the Center for Backyard Astrophysics. Dur…
The Death Spiral of T Pyxidis
Joseph Patterson, Arto Oksanen, Berto Monard +12
We report a long campaign to track the 1.8 hr photometric wave in the recurrent nova T Pyxidis, using the global telescope network of the Center for Backyard Astrophysics. During 1…
An Isolated Stellar-Mass Black Hole Detected Through Astrometric Microlensing
Kailash C. Sahu, Jay Anderson, Stefano Casertano +90
We report the first unambiguous detection and mass measurement of an isolated stellar-mass black hole (BH). We used the Hubble Space Telescope (HST) to carry out precise astrometry…
The asynchronous polar V1432 Aquilae and its path back to synchronism
David Boyd, Joseph Patterson, William Allen +23
V1432 Aquilae is the only known eclipsing asynchronous polar. In this respect it is unique and therefore merits our attention. We report the results of a 15-year campaign by the gl…
Development of a Robotic System for Automated Decaking of 3D-Printed Parts
Huy Nguyen, Nicholas Adrian, Joyce Lim Xin Yan +3
With the rapid rise of 3D-printing as a competitive mass manufacturing method, manual "decaking" - i.e. removing the residual powder that sticks to a 3D-printed part - has become a…
Maximizing the Spread of Cascades Using Network Design
Daniel Sheldon, Bistra Dilkina, Adam N. Elmachtoub +8
We introduce a new optimization framework to maximize the expected spread of cascades in networks. Our model allows a rich set of actions that directly manipulate cascade dynamics…
