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…
The Next Generation Virgo Cluster Survey (NGVS). II. A Catalog of Galaxies in the Virgo Cluster
Laura Ferrarese, Patrick Cote, Lauren A. MacArthur +51
The Next Generation Virgo Cluster Survey (NGVS) is a deep, high resolution imaging campaign that used the 1 deg MegaCam instrument on the Canada-France-Hawaii Telescope to carr…
DragonflyPol: Wide-Field Optical Linear Polarimetry with the Dragonfly Telephoto Array (Instrument Description and Commissioning)
Mehrnoosh Tahani, Leo Hollberg, Hiroshi Akitaya +9
The paper presents DragonflyPol, a wide-field optical linear polarimetry system built on the Dragonfly Telephoto Array, describing its modular design, laboratory characterization o…
dfcosmic: A Python package for cosmic ray removal
Carter Lee Rhea, Pieter van Dokkum, Steven R. Janssens +5
Astronomical images often show sharp features that are caused by cosmic ray (CR) hits, hot pixels, or non-Gaussian noise. L.A.Cosmic (van Dokkum 2001) is a widely used edge detecti…
Quantitative Morphology of Galactic Cirrus in Deep Optical Imaging
Qing Liu, Peter Martin, Roberto Abraham +9
Imaging of optical Galactic cirrus, the spatially resolved form of diffuse Galactic light, provides important insights into the properties of the diffuse interstellar medium (ISM)…
Mapping Galactic Winds and Small-scale Structure in the Circumgalactic Medium with Habitable Worlds Observatory
Joseph N. Burchett, Deborah M. Lokhorst, Yakov Faerman +4
We present a science case for the Habitable Worlds Observatory (HWO) to map the circumgalactic medium (CGM) in emission by targeting ultraviolet emission lines, which trace the 10^…
