The Herschel-SPIRE instrument and its in-flight performance
- M. Griffin, A. Abergel, E. Zonca
- 27 May 2010
Physics
The Spectral and Photometric Imaging REceiver (SPIRE), is the Herschel Space Observatory`s submillimetre camera and spectrometer. It contains a three-band imaging photometer operating at 250, 350 and…
A Herschel PACS and SPIRE study of the dust content of the Cassiopeia A supernova remnant
- M. Barlow, O. Krause, E. Polehampton
- 15 May 2010
Physics
Using the 3.5-m Herschel Space Observatory, imaging photometry of Cas A has been obtained in six bands between 70 and 500 μm with the PACS and SPIRE instruments, with angular resolutions ranging from…
The VST Photometric Hα Survey of the Southern Galactic Plane and Bulge (VPHAS
- J. Drew, E. González-Solares, A. Zijlstra
- 27 February 2014
Physics
The VST Photometric HSurvey of the Southern Galactic Plane and Bulge (VPHAS+) is surveying the southern Milky Way in u,g,r,i and Hat �1 arcsec angular resolution. Its footprint spans the Galactic…
A STUBBORNLY LARGE MASS OF COLD DUST IN THE EJECTA OF SUPERNOVA 1987A
- M. Matsuura, E. Dwek, J. Yates
- 26 November 2014
Physics
We present new Herschel photometric and spectroscopic observations of Supernova 1987A, carried out in 2012. Our dedicated photometric measurements provide new 70 μm data and improved imaging quality…
The abundance discrepancy – recombination line versus forbidden line abundances for a northern sample of galactic planetary nebulae
- R. Wesson, Xiaowei Liu, M. Barlow
- 11 September 2005
Physics
We present deep optical spectra of 23 galactic planetary nebulae, which are analysed in conjunction with archival infrared and ultraviolet spectra. We derive nebular electron temperatures based on…
EVIDENCE FOR PRE-EXISTING DUST IN THE BRIGHT TYPE IIn SN 2010jl
- J. Andrews, G. Clayton, D. Welch
- 3 June 2011
Physics
SN 2010jl was an extremely bright, Type IIn supernova (SN) which showed a significant infrared (IR) excess no later than 90 days after explosion. We have obtained Spitzer 3.6 and 4.5 μm and JHK…
The dust mass in Cassiopeia A from a spatially resolved Herschel analysis
- I. D. Looze, M. Barlow, R. Wesson
- 2 November 2016
Physics, Geology
Theoretical models predict that core-collapse supernovae (CCSNe) can be efficient dust producers (0.1–1.0 M⊙), potentially accounting for most of the dust production in the early Universe.…
Large dust grains in the wind of VY Canis Majoris
- P. Scicluna, R. Siebenmorgen, S. Wolf
- 24 November 2015
Physics
Massive stars live short lives, losing large amounts of mass through their stellar wind. Their mass is a key factor determining how and when they explode as supernovae, enriching the interstellar…
A “FIREWORK” OF H2 KNOTS IN THE PLANETARY NEBULA NGC 7293 (THE HELIX NEBULA)
- M. Matsuura, A. Speck, R. Wesson
- 8 July 2009
Physics
We present a deep and wide field-of-view (4′ × 7′) image of the planetary nebula (PN) NGC 7293 (the Helix Nebula) in the 2.12 μm H2 v = 1 → 0 S(1) line. The excellent seeing (0.″4) at the Subaru…
Dust in historical Galactic Type Ia supernova remnants with Herschel★
- H. Gomez, C. Clark, R. Wesson
- 28 November 2011
Physics, Geology
Monthly notices of the Royal Astronomical Society
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. Recently, large…
