The Nearby Star Formation and Supernova Histories Reconstructed from Young Star Clusters
Cameren Swiggum, Catherine Zucker, Michelangelo Pantaleoni González +8
We reconstruct the recent star formation and core-collapse supernova (ccSN) histories of the Solar Neighborhood from the past trajectories of young star clusters. Using a \textit{G…
Milky Way Atlas: A radial-velocity-resolved, three-dimensional map of H I within 1.25 kpc
Lewis McCallum, Laurin Söding, Mareike Berkner +9
We present a velocity-resolved three-dimensional map of local atomic hydrogen (HI) within 1.25 kpc of the Sun, tackling the challenge of converting emission from position-position-…
The radial component of the local Galactic magnetic field in 3D
Lewis McCallum, Philipp Frank, Sebastian Hutschenreuter +9
We present a distance-resolved reconstruction of the local line-of-sight Galactic magnetic field, , by combining a 3D electron density () map derived from dust map-i…
WASP-12, shrouded in mystery or just cold gas?
Simon Daley-Yates, Ricarda Beckmann, Lewis McCallum +2
Observations of the planet-hosting star WASP-12 show a distinctive depression in the \ion{Mg}{ii} and \ion{Ca}{ii} resonance lines. This has been interpreted as a marker of atmosph…
SDSO1 is a Shocked Ghost Planetary Nebula in Front of M 31
Patrick Ogle, Mark Petersen, R. Michael Rich +12
We present new, deep narrowband imagery and discuss the nature of SDSO 1, the large [O III]-emitting nebula centered 1.5 degrees SE of M 31. We find strong evidence to support the…
A three-dimensional, multi-wavelength view and time-dependent analysis of the Milky Way's local ionized gas
Lewis McCallum, Kenneth Wood, Robert Benjamin +2
This work is the continuation of a series attempting to characterize the local warm ionized medium through both static and time dependent simulations. We build upon our three dimen…
Origin of the IRAS Vela Shell: New Insights from 3D Dust Mapping
Bore Annie Gao, Catherine Zucker, Tirupati Kumara Sridharan +15
The IRAS Vela Shell (IVS) is a structure of enhanced FIR emission located towards the Gum Nebula, a prominent region of emission in the local Milky Way shaped by various g…
The H sky in three dimensions
Lewis McCallum, Kenneth Wood, Robert Benjamin +4
We combine parallax distances to nearby O stars with parsec-scale resolution three-dimensional dust maps of the local region of the Milky Way (within 1.25 kpc of the Sun) to simula…
Time-dependent metal ionization and the persistence of collisionally excited emission lines in the diffuse ionized gas of star forming galaxies
Lewis McCallum, Kenneth Wood, Robert Benjamin +2
We extend our time-dependent hydrogen ionization simulations of diffuse ionized gas to include metals important for collisional cooling and diagnostic emission lines. The combinati…
JWST MIRI and NIRCam observations of NGC 891 and its circumgalactic medium
Jérémy Chastenet, Ilse De Looze, Monica Relaño +37
We present new JWST observations of the nearby, prototypical edge-on, spiral galaxy NGC 891. The northern half of the disk was observed with NIRCam in its F150W and F277W filters.…
The persistence of high altitude non-equilibrium diffuse ionized gas in simulations of star forming galaxies
Lewis McCallum, Kenneth Wood, Robert Benjamin +4
Widespread, high altitude, diffuse ionized gas with scale heights of around a kiloparsec is observed in the Milky Way and other star forming galaxies. Numerical radiation-magnetohy…
