Automated crater shape retrieval using weakly-supervised deep learning
Mohamad Ali-Dib, Kristen Menou, Alan P. Jackson +2
Crater ellipticity determination is a complex and time consuming task that so far has evaded successful automation. We train a state of the art computer vision algorithm to identif…
Parametric resonance of a Bose-Einstein condensate in a ring trap with periodically driven interactions
Chen-Xi Zhu, Wei Yi, Guang-Can Guo +1
We study the instability of a ring Bose-Einstein condensate under a periodic modulation of inter-atomic interactions. The condensate exhibits temporal and spatial patterns induced…
Lunar Crater Identification via Deep Learning
Ari Silburt, Mohamad Ali-Dib, Chenchong Zhu +5
Crater counting on the Moon and other bodies is crucial to constrain the dynamical history of the Solar System. This has traditionally been done by visual inspection of images, thu…
Magnetized Moving Mesh Merger of a Carbon-Oxygen White Dwarf Binary
Chenchong Zhu, Rudiger Pakmor, Marten H. van Kerkwijk +1
White dwarf (WD) binary mergers are possible progenitors to a number of unusual stars and transient phenomena, including type Ia supernovae. To date, simulations of mergers have no…
Improving the convergence properties of the moving-mesh code AREPO
Ruediger Pakmor, Volker Springel, Andreas Bauer +5
Accurate numerical solutions of the equations of hydrodynamics play an ever more important role in many fields of astrophysics. In this work, we reinvestigate the accuracy of the m…
The Physics and End-Products of Merging CO WD Binaries
Chenchong Zhu
The merger of two carbon-oxygen white dwarfs has long been theorized to lead to a massive carbon-oxygen or oxygen-neon white dwarf, accretion-induced collapse to a neutron star, or…
A Parameter-Space Study of Carbon-Oxygen White Dwarf Mergers
Chenchong Zhu, Philip Chang, Marten van Kerkwijk +1
The merger of two carbon-oxygen white dwarfs can lead either to a spectacular transient, stable nuclear burning or a massive, rapidly rotating white dwarf. Simulations of mergers h…
Properties of Carbon-Oxygen White Dwarf Merger Remnants
Chenchong Zhu, Philip Chang, Marten van Kerkwijk +1
Recent studies have shown that for suitable initial conditions both super- and sub-Chandrasekhar mass carbon-oxygen white dwarf mergers produce explosions similar to observed SNe I…
Observation of quantum diffractive collisions using shallow atomic traps
David E. Fagnan, Jicheng Wang, Chenchong Zhu +4
We present measurements and calculations of the trap loss rate for laser cooled Rb atoms confined in either a magneto-optic or a magnetic quadrupole trap when exposed to a room tem…
