    • A new polarization amplitude bias reduction method 
      Vidal, Matías; Leahy, J. P.; Dickinson, C. (2016)
      Polarization amplitude estimation is affected by a positive noise bias, particularly important in regions with low signal-to-noise ratio (SNR). We present a new approach to correct for this bias in the case there is ...
    • Cm-wavelength observations of MWC 758: Resolved dust trapping in a vortex 
      Casassus Montero, Simón; Marino, Sebastián; Lyra, Wladimir; Baruteau, Clément; Vidal, Matías; Wootten, Alwyn; Pérez, Sebastián; Alarcon, Felipe; Barraza, Marcelo; Cárcamo, Miguel; Dong, Ruobing; Sierra, Anibal; Zhu, Zhaohuan; Ricci, Luca; Christiaens, Valentin; Cieza, Lucas (Oxford University Press, 2019)
      © 2018 The Author(s)The large crescents imaged by ALMA in transition discs suggest that azimuthal dust trapping concentrates the larger grains, but centimetre–wavelengths continuum observations are required to map the ...
    • Modelling the spinning dust emission from LDN1780 
      Vidal, Matías; Dickinson, Clive; Harper, S. E.; Casassus Montero, Simón; Witt, A. N. (Oxford University Press, 2020)
      We study the anomalous microwave emission (AME) in the Lynds Dark Nebula (LDN) 1780 on two angular scales. With publicly available data at an angular resolution of 1 degrees, we studied the spectral energy distribution of ...
    • The State-of-Play of Anomalous Microwave Emission (AME) research 
      Dickinson, Clive; Ali-Haïmoud, Y.; Barr, A.; Battistelli, E.; Bell, A.; Bernstein, L.; Casassus Montero, Simón; Cleary, K.; Draine, B.; Génova-Santos, R.; Harper, S.; Hensley, B.; Hill-Valler, J.; Hoang, Thiem; Israel, F.; Jew, L.; Lazarian, A.; Leahy, J.; Leech, J.; López-Caraballo, C.; McDonald, I.; Murphy, E.; Onaka, T.; Paladini, R.; Peel, M.; Perrott, Y.; Poidevin, F.; Readhead, A.; Rubiño-Martín, J.; Taylor, A.; Tibbs, C.; Todorović, M.; Vidal, Matías (Elsevier B.V., 2018)
      Anomalous Microwave Emission (AME) is a component of diffuse Galactic radiation observed at frequencies in the range ≈ 10–60 GHz. AME was first detected in 1996 and recognised as an additional component of emission in 1997. ...
