Effects of temperature-dependent optical properties on the determination of interstellar dust masses

Lapo Fanciullo, Jonathan P. Marshall, Francisca Kemper +2

Accurate measurements of interstellar dust mass are key to answering several astrophysical questions. A common method of obtaining the mass is to fit the far-infrared thermal emiss…

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…

Large Interstellar Polarisation Survey. III. Observational constraints on the structure of grains

Ralf Siebenmorgen, Stefano Bagnulo, Lapo Fanciullo +2

Dust in the diffuse interstellar medium remains incompletely understood with regard to the structure, composition, size distribution, and alignment properties of the grains. Joint…

{\sc ampere}: A tool to fit heterogeneous observations consistently

P. Scicluna, S. Zeegers, J. P. Marshall +5

As astronomy advances and data becomes more complex, models and inference also become more expensive and complex. In this paper we present {\sc ampere}, which aims to solve this pr…

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…

The JCMT BISTRO Survey: Unveiling the Magnetic Fields around Galactic Center

Meng-Zhe Yang, Shih-Ping Lai, Janik Karoly +40

We acquired 450 μm and 850 μm dust continuum polarization observations toward the inner region of the Central Molecular Zone (CMZ) as part of the B-Fields In Star-Forming Region…
