News Sentiment as Leading Indicators for Recessions
Melody Y. Huang, Randall R. Rojas, Patrick D. Convery
In the following paper, we use a topic modeling algorithm and sentiment scoring methods to construct a novel metric that serves as a leading indicator in recession prediction model…
Closed-form Solutions of Relativistic Black-Scholes Equations
Yanlin Qu, Randall R. Rojas
Drawing insights from the triumph of relativistic over classical mechanics when velocities approach the speed of light, we explore a similar improvement to the seminal Black-Schole…
Photometric Properties of Void Galaxies in the Sloan Digital Sky Survey DR7 Data Release
Fiona Hoyle, Michael S. Vogeley, Danny Pan
Using the sample presented in Pan:2011, we analyse the photometric properties of 88,794 void galaxies and compare them to galaxies in higher density environments with the same abso…
Spectroscopic Properties of Void Galaxies in the Sloan Digital Sky Survey
Randall R. Rojas, Michael S. Vogeley, Fiona Hoyle +1
We study the spectroscopic properties of a sample of 10^3 void galaxies from the Sloan Digital Sky Survey (SDSS) and compare these with the properties of galaxies in higher density…
Mapping the Cosmic Web with the Sloan Digital Sky Survey
Michael S. Vogeley, Fiona Hoyle, Randall R. Rojas +1
Wide-angle, moderately deep redshift surveys such as that conducted as part of the Sloan Digital Sky Survey (SDSS) allow study of the relationship between the structural elements o…
The Mass Function of Void Galaxies in the SDSS Data Release 2
David M. Goldberg, Timothy D. Jones, Fiona Hoyle +3
We estimate the Mass Function of void galaxies in the second public data release of the Sloan Digital Sky Survey from a sample of 1000 galaxies with local density contrasts of delt…
