Resolved spectral variations of the centimetre-wavelength continuum from the rho Oph W photo-dissociation-region
Simon Casassus, Matias Vidal, Carla Arce-Tord +5
Cm-wavelength radio continuum emission in excess of free-free, synchrotron and Rayleigh-Jeans dust emission (excess microwave emission, EME), and often called `anomalous microwave…
Resolved observations at 31 GHz of spinning dust emissivity variations in Oph
Carla Arce-Tord, Matias Vidal, Simon Casassus +9
The Oph molecular cloud is one of the best examples of spinning dust emission, first detected by the Cosmic Background Imager (CBI). Here we present 4.5 arcmin observations wit…
Modelling the spinning dust emission from LDN 1780
Matias Vidal, Clive Dickinson, S. E. Harper +2
We study the anomalous microwave emission (AME) in the Lynds Dark Nebula (LDN) 1780 on two angular scales. Using available ancillary data at an angular resolution of 1 degree, we c…
Cm-wavelength observations of MWC758: resolved dust trapping in a vortex
Simon Casassus, Sebastian Marino, Wladimir Lyra +13
The large crescents imaged by ALMA in transition disks suggest that azimuthal dust trapping concentrates the larger grains, but centimetre-wavelengths continuum observations are re…
The State-of-Play of Anomalous Microwave Emission (AME) Research
Clive Dickinson, Y. Ali-Haïmoud, A. Barr +30
Anomalous Microwave Emission (AME) is a component of diffuse Galactic radiation observed at frequencies in the range -60 GHz. AME was first detected in 1996 and recogni…
