Fast Period Searches Using the Lomb-Scargle Algorithm on Graphics Processing Units for Large Datasets and Real-Time Applications
Michael Gowanlock, Daniel Kramer, David E. Trilling +2
Computing the periods of variable objects is well-known to be computationally expensive. Modern astronomical catalogs contain a significant number of observed objects. Therefore, e…
The Breakthrough Listen Search For Intelligent Life Near the Galactic Center I
Vishal Gajjar, Karen I. Perez, Andrew P. V. Siemion +23
A line-of-sight towards the Galactic Center (GC) offers the largest number of potentially habitable systems of any direction in the sky. The Breakthrough Listen program is undertak…
Hybrid KNN-Join: Parallel Nearest Neighbor Searches Exploiting CPU and GPU Architectural Features
Michael Gowanlock
K Nearest Neighbor (KNN) joins are used in scientific domains for data analysis, and are building blocks of several well-known algorithms. KNN-joins find the KNN of all points in a…
GPU Accelerated Similarity Self-Join for Multi-Dimensional Data
Michael Gowanlock, Ben Karsin
The self-join finds all objects in a dataset that are within a search distance, epsilon, of each other; therefore, the self-join is a building block of many algorithms. We advance…
GPU Accelerated Self-join for the Distance Similarity Metric
Michael Gowanlock, Ben Karsin
The self-join finds all objects in a dataset within a threshold of each other defined by a similarity metric. As such, the self-join is a building block for the field of databases…
The Habitability of our Evolving Galaxy
Michael G. Gowanlock, Ian S. Morrison
The notion of a Galactic Habitable Zone (GHZ), or regions of the Milky Way galaxy that preferentially maintain the conditions to sustain complex life, has recently gained attention…
