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-…
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…
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…
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…
