Simultaneous PSF Matching via Dual Kernel Optimization
Carter Lee Rhea, Pieter Van Dokkum, Roberto Abraham +6
Standard point spread function (PSF) matching algorithms consider one image as the reference and aim to find a convolution kernel such that, when applied to the reference image, th…
Numerous bow shocks in the outer Helix Nebula
Pieter van Dokkum, Roberto Abraham, William P. Bowman +5
Near the end of their lives, low- and intermediate-mass stars expel metal-enriched material in winds and outflows, ultimately producing planetary nebulae (PNe). The ejected materia…
Predicting the Kinematics of the Cold Circumgalactic Medium from its Morphology using Convolutional Neural Networks
Connor Jennings, Earl P. Bellinger, Imad Pasha +2
We present a novel approach to predicting plane-of-sky velocities of cold gas clouds in the circumgalactic medium (CGM) of galaxies. The method uses a convolutional neural network…
The extended globular cluster system of the archetypal "failed galaxy" Dragonfly-44 from deep white-light Hubble Space Telescope imaging
Maria Luisa Buzzo, Pieter van Dokkum, Roberto Abraham +2
For nearly a decade, Dragonfly-44 (DF44, ) has been considered an archetypal ``failed galaxy'', a system so rich in globular clusters (GCs)…
DragonflyPol: Wide-Field Optical Linear Polarimetry with the Dragonfly Telephoto Array (Instrument Description and Commissioning)
Mehrnoosh Tahani, Leo Hollberg, Hiroshi Akitaya +9
We present DragonflyPol, a wide-field optical linear polarimetry capability implemented on the Dragonfly Telephoto Array. DragonflyPol leverages Dragonfly's modular, multi-lens arc…
A Census of the 200 Most Massive Galaxies Spectroscopically Observed with JWST at zspec 3-15
Mengyuan Xiao, Pascal A. Oesch, Longji Bing +26
Massive galaxies provide strong tests of galaxy formation models, yet a comprehensive spectroscopic view of their properties and demographics in the early Universe has remained elu…
