Little Blue Dots in the Hubble Space Telescope Frontier Fields: Precursors to Globular Clusters?
Debra Meloy Elmegreen, Bruce G. Elmegreen
Galaxies with stellar masses <10^7 Msun and specific star formation rates sSFR>10^{-7} yr^{-1} were examined on images of the Hubble Space Telescope Frontier Field Parallels for Ab…
Testing the performance and accuracy of the RELXILL model for the relativistic X-ray reflection from accretion disks
Kishalay Choudhury, Javier A. Garcia, James F. Steiner +1
The reflection spectroscopic model RELXILL is commonly implemented in studying relativistic X-ray reflection from accretion disks around black holes. We present a systematic study…
Dynamical Imaging with Interferometry
Michael D. Johnson, Katherine L. Bouman, Lindy Blackburn +7
By linking widely separated radio dishes, the technique of very long baseline interferometry (VLBI) can greatly enhance angular resolution in radio astronomy. However, at any given…
Up and Down the Black Hole Radio/X-ray Correlation: the 2017 mini-outbursts from Swift J1753.5-0127
R. M. Plotkin, J. Bright, J. C. A. Miller-Jones +20
The candidate black hole X-ray binary Swift J1753.5-0127 faded to quiescence in 2016 November, after a prolonged outburst that was discovered in 2005. Nearly three months later the…
Thick Disks in the Hubble Space Telescope Frontier Fields
Bruce G. Elmegreen, Debra Meloy Elmegreen, Brittany Tompkins +1
Thick disk evolution is studied using edge-on galaxies in two Hubble Space Telescope Frontier Field Parallels. The galaxies were separated into 72 clumpy types and 35 spiral types…
Deep Bilateral Learning for Real-Time Image Enhancement
Michaël Gharbi, Jiawen Chen, Jonathan T. Barron +2
Performance is a critical challenge in mobile image processing. Given a reference imaging pipeline, or even human-adjusted pairs of images, we seek to reproduce the enhancements an…
