HCO and the Effect of Mixing in SN 1987A
H. M. Davies, M. Matsuura, H. L. Gomez +8
We present high angular resolution observations of the HCO emission in the central ejecta of the supernova remnant SN 1987A using the Atacama Large Millimeter Array (ALMA). We…
MUSE Imaging Spectroscopy of the Fullerene Planetary Nebula Tc 1
J. R. Walsh, M. J. Barlow, A. Monreal-Ibero +6
The planetary nebula Tc 1 (PN G345.2 -08.8), one of the rare group of Galactic PNe showing fullerene emission in the infrared, was observed with MUSE wide field mode with adaptive…
Detection of C Combination Bands in the Near-IR Spectrum of Tc 1
Morgan M. Giese, Vincent J. Esposito, Simon Van Schuylenbergh +26
We report the detection of a set of new near-infrared emission features between 3.5 and 5.2 m in JWST/NIRSpec observations of Tc 1, the planetary nebula known for displaying th…
Milky Way's warped disc traced by AGB stars
Tanya Kushwahaa, Mikako Matsuura, Jason A. S. Hunt +3
While the presence of the Galactic warp has long been established from observations of \HI\, gas, the \textit{Gaia} measurements of over 1 billion stars with parallaxes have enable…
3D insights into SN 1987A: ALMA observations compared to hydrodynamical explosion simulations
R. Wesson, M. Gabler, M. Lyons +9
We obtain three-dimensional distributions of CO and SiO molecules from high spatial resolution (0.03--0.06") ALMA observations of SN 1987A at two different epochs. The evolution be…
WEAVE imaging spectroscopy of NGC 6720: an iron bar in the Ring
R. Wesson, J. E. Drew, M. J. Barlow +23
We present spatially resolved spectroscopic observations of the planetary nebula NGC 6720, the Ring Nebula, taken during the science verification phase of WEAVE, a new instrument m…
