Spatially Resolved Chandra HETG Spectroscopy of the NLR Ionization Cone in NGC 1068
Daniel A. Evans, Patrick M. Ogle, Herman L. Marshall +9
We present initial results from a new 440-ks Chandra HETG GTO observation of the canonical Seyfert 2 galaxy NGC 1068. The proximity of NGC 1068, together with Chandra's superb spat…
On the Chudnovsky-Seymour-Sullivan Conjecture on Cycles in Triangle-free Digraphs
Kevin Chen, Sean Karson, Dan Liu +1
For a simple digraph without directed triangles or digons, let be the size of the smallest subset such that has no directed cycles, and…
The Case for RodentStore, an Adaptive, Declarative Storage System
Philippe Cudre-Mauroux, Eugene Wu, Sam Madden
Recent excitement in the database community surrounding new applications?analytic, scientific, graph, geospatial, etc.?has led to an explosion in research on database storage syste…
Ultrafast High-pressure AC Electro-osmotic Pumps for Portable Biomedical Microfluidics
Chien-Chih Huang, Martin Z. Bazant, Todd Thorsen
This paper details the development of an integrated AC electro-osmotic (ACEO) microfluidic pump for dilute electrolytes consisting of a long serpentine microchannel lined with thre…
Imaging an Event Horizon: submm-VLBI of a Super Massive Black Hole
Sheperd Doeleman, Eric Agol, Don Backer +20
A long standing goal in astrophysics is to directly observe the immediate environment of a black hole with angular resolution comparable to the event horizon. Realizing this goal w…
The R-evolution of QCD matrix elements
Andre H. Hoang, Ambar Jain, Ignazio Scimemi +1
Perturbation series in QCD are generally asymptotic and suffer from so-called infrared renormalon ambiguities. In the context of the standard operator product expansion in MS-bar t…
