Grain alignment and dust evolution physics with polarisation (GRADE-POL). II. On the physical basis of Serkowski and super-Serkowski polarisation spectra
Le Ngoc Tram, Thiem Hoang, B-G Andersson +4
Optical-to-near-infrared interstellar polarisation, induced by aligned dust grains, generally follows a convex wavelength dependence, known as the Serkowski relation. However, obse…
Probing Anomalous Microwave Emission with the Square Kilometre Array
MatÃas Vidal, Simón Casassus, Roke Cepeda-Arroita +15
Anomalous microwave emission (AME) represents an excess of radiation in the 10-60 GHz range, distinct from synchrotron, free-free, or thermal dust emission. Although most commonly…
Recovering 3D Magnetic Turbulence from Single-Frequency Faraday Screens
Aliaksandr Melnichenka, Alex Lazarian, Dmitri Pogosyan
Statistics of polarized synchrotron radiation carry information about the properties of the underlying turbulence. Different statistical measures constructed from observables probe…
Unveiling the 3D structure of the central molecular zone from stellar kinematics and photometry: The 50 and 20 km/s clouds
Francisco Nogueras-Lara, Ashley T. Barnes, Jonathan D. Henshaw +25
The central molecular zone (CMZ), surrounding the Galactic centre, is the largest reservoir of dense molecular gas in the Galaxy. Despite its relative proximity, the 3D structure o…
Grain alignment and dust evolution physics with polarisation (GRADE-POL). I. Dust polarisation modelling for isolated starless cores
Le Ngoc Tram, Thiem Hoang, Alex Lazarian +6
The polarisation of light induced by aligned interstellar dust serves as a significant tool in investigating cosmic magnetic fields, dust properties, and poses a challenge in chara…
