Brightening X-ray Emission from GW170817/GRB170817A: Further Evidence for an Outflow
John J. Ruan, Melania Nynka, Daryl Haggard +2
The origin of the X-ray emission from neutron star coalescence GW170817/GRB170817A is a key diagnostic of the unsettled post-merger narrative, and different scenarios predict disti…
Branching Brownian motion with decay of mass and the non-local Fisher-KPP equation
Louigi Addario-Berry, Julien Berestycki, Sarah Penington
In this work we study a non-local version of the Fisher-KPP equation, \begin{equation*} \begin{cases} \frac{\partial u}{\partial t}=\tfrac{1}{2}Δu +u (1- ϕ\ast u), \quad t>0, \quad…
Quasar outflow energetics from broad absorption line variability
S. M. McGraw, J. C. Shields, F. W. Hamann +2
Quasar outflows have long been recognized as potential contributors to the co-evolution between supermassive black holes (SMBHs) and their host galaxies. The role of outflows in AG…
Learning Seasonal Phytoplankton Communities with Topic Models
Arnold Kalmbach, Heidi M. Sosik, Gregory Dudek +1
In this work we develop and demonstrate a probabilistic generative model for phytoplankton communities. The proposed model takes counts of a set of phytoplankton taxa in a timeseri…
The Sleeping Monster: NuSTAR observations of SGR 1806-20, 11 years after the Giant Flare
George Younes, Matthew G. Baring, Chryssa Kouveliotou +5
We report the analysis of 5 NuSTAR observations of SGR 1806-20 spread over a year from April 2015 to April 2016, more than 11 years following its Giant Flare (GF) of 2004. The sour…
Probabilistic Available Delivery Capability Assessment of General Distribution Network with Renewables
Hao Sheng, Xiaozhe Wang
Rapid increase of renewable energy sources and electric vehicles in utility distribution feeders introduces more and more uncertainties. To investigate how such uncertainties may a…
