HST Proper Motions of Andromeda V and VI
Dana I. Casetti-Dinescu, Marcel S. Pawlowski, Terrence M. Girard +3
We measure the absolute proper motions of Andromeda V (And V) and Andromeda VI/Pegasus (And VI) dwarf galaxies, satellites of M31 located near its galactic plane. And VI is located…
HST Proper Motion of Andromeda III: Another Satellite Co-orbiting The M31 Satellite Plane
Dana I. Casetti-Dinescu, Marcel S. Pawlowski, Terrence M. Girard +5
We measure the absolute proper motion of Andromeda III using ACS/WFC and WFPC2 exposures spanning an unprecedented 22-year time baseline. The WFPC2 exposures have been processed us…
HST/JWST Long-Term Monitoring Working Group Final Report
Saurabh W. Jha, Dana I. Casetti-Dinescu, Gary M. Bernstein +9
The Astro2020 Decadal Survey recognizes time-domain astronomy as a key science area over the next decade and beyond. With over 30 years of HST data and the potential for 20 years o…
Star-Image Centering with Deep Learning II: HST/WFPC2 Full Field of View
Dana I. Casetti-Dinescu, Roberto Baena-Galle, Terrence M. Girard +2
We present an expanded and improved deep-learning (DL) methodology for determining centers of star images on HST/WFPC2 exposures. Previously, we demonstrated that our DL model can…
Star-Image Centering with Deep Learning: HST/WFPC2 Images
Dana I. Casetti-Dinescu, Terrence M. Girard, Roberto Baena-Galle +2
A Deep Learning (DL) algorithm is built and tested for its ability to determine centers of star images on HST/WFPC2 exposures, in filters F555W and F814W. These archival observatio…
A New Proper Motion Determination of Leo I
Dana I. Casetti-Dinescu, Caitlin K. Hansen, Terrence M. Girard +3
We measure the absolute proper motion of Leo I using a WFPC2/HST data set that spans up to 10 years, to date the longest time baseline utilized for this satellite. The measurement…
