Autoencoder Reconstruction of Cosmological Microlensing Magnification Maps
Somayeh Khakpash, Federica Bianco, Georgios Vernardos +2
Enhanced modeling of microlensing variations in light curves of strongly lensed quasars improves measurements of cosmological time delays, the Hubble Constant, and quasar structure…
Data Compression in the Petascale Astronomy Era: a GERLUMPH case study
Dany Vohl, Christopher J. Fluke, Georgios Vernardos
As the volume of data grows, astronomers are increasingly faced with choices on what data to keep -- and what to throw away. Recent work evaluating the JPEG2000 (ISO/IEC 15444) sta…
GERLUMPH Data Release 2: 2.5 billion simulated microlensing light curves
Georgios Vernardos, Christopher J. Fluke, Nicholas F. Bate +2
In the upcoming synoptic all--sky survey era of astronomy, thousands of new multiply imaged quasars are expected to be discovered and monitored regularly. Light curves from the ima…
Adventures in the microlensing cloud: large datasets, eResearch tools, and GPUs
Georgios Vernardos, Christopher J Fluke
As astronomy enters the petascale data era, astronomers are faced with new challenges relating to storage, access and management of data. A shift from the traditional approach of c…
