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…
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…
Shockingly Bright Warm Carbon Monoxide Molecular Features in the Supernova Remnant Cassiopeia A Revealed by JWST
J. Rho, S. -H. Park, R. Arendt +36
We present JWST NIRCam (F356W and F444W filters) and MIRI (F770W) images and NIRSpec- IFU spectroscopy of the young supernova remnant Cassiopeia A (Cas A). We obtained the data as…
Revisiting the dust destruction efficiency of supernovae
F. D. Priestley, H. Chawner, M. Matsuura +3
Dust destruction by supernovae is one of the main processes removing dust from the interstellar medium (ISM). Estimates of the efficiency of this process, both theoretical and obse…
A Dust Twin of Cas A: Cool Dust and 21-micron Silicate Dust Feature in the Supernova Remnant G54.1+0.3
J. Rho, H. L. Gomez, A. Boogert +4
We present infrared (IR) and submillimeter observations of the Crab-like supernova remnant (SNR) G54.1+0.3 including 350 micron (SHARC-II), 870 micron (LABOCA), 70, 100, 160, 250,…
Very Deep Inside the SN 1987A Core Ejecta: Molecular Structures Seen in 3D
F. J. Abellán, R. Indebetouw, J. M. Marcaide +21
Most massive stars end their lives in core-collapse supernova explosions and enrich the interstellar medium with explosively nucleosynthesized elements. Following core collapse, th…
The dust mass in Cassiopeia A from a spatially resolved Herschel analysis
I. De Looze, M. J. Barlow, B. M. Swinyard +4
Theoretical models predict that core-collapse supernovae (CCSNe) can be efficient dust producers (0.1-1.0 Msun), potentially accounting for most of the dust production in the early…
A stubbornly large mass of cold dust in the ejecta of Supernova 1987A
M. Matsuura, E. Dwek, M. J. Barlow +33
We present new Herschel photometric and spectroscopic observations of Supernova 1987A, carried out in 2012. Our dedicated photometric measurements provide new 70 micron data and im…
Carbon Monoxide in the Cold Debris of Supernova 1987A
J. Kamenetzky, R. McCray, R. Indebetouw +27
We report spectroscopic and imaging observations of rotational transitions of cold CO and SiO in the ejecta of SN1987A, the first such emission detected in a supernova remnant. In…
The Herschel Exploitation of Local Galaxy Andromeda (HELGA). VI. The distribution and properties of molecular cloud associations in M31
Jason M. Kirk, Walter K. Gear, Jacopo Fritz +18
In this paper we present a catalogue of Giant Molecular Clouds (GMCs) in the Andromeda (M31) galaxy extracted from the Hershel Exploitation of Local Galaxy Andromeda (HELGA) datase…
Dust in Historical Galactic Type Ia Supernova Remnants with Herschel
H. L. Gomez, C. J. R. Clark, T. Nozawa +13
The origin of interstellar dust in galaxies is poorly understood, particularly the relative contributions from supernovae and the cool stellar winds of low-intermediate mass stars.…
Submillimetre Variability of Eta Carinae: cool dust within the outer ejecta
H. L. Gomez, C. Vlahakis, C. M. Stretch +5
Previous submillimetre (submm) observations detected 0.7 solar masses of cool dust emission around the Luminous Blue Variable (LBV) star Eta Carinae. These observations were hinder…
Iron Needles in Supernova Remnants?
H L Gomez, L Dunne, S Eales +2
It has been suggested by Dwek (2004) that iron needles could explain the submillimetre emission from the Cas A supernova remnant (SNR) with only a very small total mass. We investi…
