Improved effective-one-body model of spinning, nonprecessing binary black holes for the era of gravitational-wave astrophysics with advanced detectors [PDF]

open access: yes, 2016
We improve the accuracy of the effective-one-body (EOB) waveforms that were employed during the first observing run of Advanced LIGO for binaries of spinning, nonprecessing black holes by calibrating them to a set of 141 numerical-relativity (NR ...

Quantifying Imperfect Cognition Via Achieved Information Gain

open access: yesAnnalen der Physik, EarlyView.
Cognition, the processing of information in the form of inference, communication, and memorization, is the central activity of any intelligence. To quantify imperfect cognition, the concept of achieved information gain (AIG) is introduced. AIG can be derived axiomatically, allows cognitive fidelity and efficiency to be defined mathematically, and ...

Direct Reactions with Exotic Nuclei, Nuclear Structure and Astrophysics [PDF]

open access: yes, 2006
Intermediate energy Coulomb excitation and dissociation is a useful tool for nuclear structure and astrophysics studies. Low-lying strength in nuclei far from stability was discovered by this method.

AutoCal: A software application for calibrating photometric data

open access: yesSouth African Journal of Science, 2016
We present a software application for the calibration of stellar magnitudes in the absence of standard stars. It uses an existing algorithm to match stars in the target’s field of view to catalogue entries and computes the average offset between the two ...

Mathematical simulation of vortex motion in the astrophysical objects on the basis of the gas-dynamic model [PDF]

open access: yesКомпьютерные исследования и моделирование, 2018
The application of a conservative numerical method of fluxes is examined for studying the vortex structures in the massive, fast-turned compact astrophysical objects, which are in self-gravity conditions.

Astrophysics in 1994 [PDF]

open access: yesPublications of the Astronomical Society of the Pacific, 1995
1994 was the year in which we saw the first images from the repaired Hubble Space Telescope; the probable detection of a diffuse intergalactic medium, a black hole in M87, and an enormous primordial deuterium abundance; the discovery of the first (and second) superluminal objects within our own galaxy; not to mention the demise of the Jovian dinosaurs.

Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect

open access: yesAdvanced Physics Research, EarlyView.
This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

Recent Astrophysics Results from ORELA and Possible Future Experiments at ORELA and SNS

open access: yes, 2002
I present some recent results from experiments at the Oak Ridge Electron Linear Accelerator (ORELA) and discuss their impact in nuclear astrophysics. I then describe some possible future nuclear astrophysics experiments at ORELA and at the Spallation ...

Enabling real-time multi-messenger astrophysics discoveries with deep learning [PDF]

open access: yesNature Reviews Physics, 2019
Multi-messenger astrophysics is a fast-growing, interdisciplinary field that combines data, which vary in volume and speed of data processing, from many different instruments that probe the Universe using different cosmic messengers: electromagnetic ...
