Exponential galaxy discs as the quasi-stationary distribution in a Markov chain model simulating stellar scattering
Jian Wu, Curtis Struck, Bruce G. Elmegreen +1
Previous models have shown that stochastic scattering of stars in a two-dimensional galaxy disc can generate a time-independent surface density distribution that is an exponential…
Orbits and action changes during star-clump encounters responsible for the origin of exponential discs in dwarf galaxies
Jian Wu, Curtis Struck, Bruce G. Elmegreen +1
Previous studies found that stellar scattering by massive clumps can lead to the formation of exponential profiles in galaxy discs, but details on how a star is moved around have n…
Stellar scattering and the formation of exponential discs in self-gravitating systems
Jian Wu, Curtis Struck, Elena D'Onghia +1
We show, using the N-body code GADGET-2, that stellar scattering by massive clumps can produce exponential discs, and the effectiveness of the process depends on the mass of scatte…
Fitting the Continuum Component of A Composite SDSS Quasar Spectrum Using CMA-ES
Jian Wu, Daniel E. Vanden Berk
Fitting the continuum component of a quasar spectrum in UV/optical band is challenging due to contamination of numerous emission lines. Traditional fitting algorithms such as the l…
X-ray and Multiwavelength Insights into the Inner Structure of High-Luminosity Disc-Like Emitters
B. Luo, W. N. Brandt, M. Eracleous +5
We present X-ray and multiwavelength studies of a sample of eight high-luminosity active galactic nuclei (AGNs) with disc-like Hβemission-line profiles selected from the Sloan Digi…
A Quasar Catalog with Simultaneous UV, Optical and X-ray Observations by Swift
Jian Wu, Daniel Vanden Berk, Dirk Grupe +6
We have compiled a catalog of optically-selected quasars with simultaneous observations in UV/optical and X-ray bands by the Swift Gamma Ray Burst Explorer. Objects in this catalog…
