A quantum theory of the alignment and polarization of very small dust grains
A quantum-mechanical theory of the smallest interstellar dust grains, predicting when their microwave glow becomes polarized — a possible contaminant of CMB B-mode searches.
-
A Radially Resolved Magnetic Field Threading the Disk of TW Hya
First radially resolved measurement of the magnetic field threading a planet-forming disk — about 10 milligauss, switching from a vertical to an in-plane orientation across a known gap.
-
Millimeter emission from supermassive black hole coronae
Compact millimeter emission from the immediate vicinity of supermassive black holes is consistent with non-thermal particle populations in their hot coronae — a new window onto the engines.
-
Many-body effects in the line radiative transfer equation
A foundational rewrite of the line radiative-transfer equation — when photons interact with molecules faster than the molecules can react individually, the gas behaves as a many-body system and the standard equation needs a correction.
-
The discovery of polarized water vapor megamaser emission in a molecular accretion disk
The first detection of linearly polarized water vapor megamaser emission in another galaxy — pinning the magnetic field of the molecular accretion disk around NGC 1068's supermassive black hole.
-
The fountain of the luminous infrared galaxy Zw049.057 as traced by its OH megamaser
A nearby buried galactic nucleus is launching a two-speed wind — a fast collimated jet that escapes, wrapped in a slower "fountain" that rains back down — traced by high-velocity HCN emission and one of the brightest OH megamasers known.
-
Hyperfine structure of the methanol molecule as traced by Class I methanol masers
Class I methanol masers light up only one specific hyperfine component at a time — and which one changes from source to source. Pinning that down sharpens methanol as a precision tool.
-
Molecular line polarisation from the circumstellar envelopes of asymptotic giant branch stars
ALMA observations and radiative-transfer modelling of polarized molecular emission in the dusty winds of two evolved stars — and a magnetic-field map that follows the wind outwards.
-
Maser polarization through anisotropic pumping
A unified maser-polarization framework that pins down how much of an observed signal is set by the magnetic field, how much is boosted by the geometry of how the maser is pumped, and where the pumping geometry can mimic a Zeeman signal.
-
Three-dimensional magnetic field imaging of protoplanetary disks using Zeeman broadening and linear polarization observations
The methodological blueprint for the technique that finally measured a magnetic field in the TW Hya disk — combining the way a field broadens unpolarized lines with how it polarizes them.
-
The generation and transformation of polarization signals in molecular lines through collective anisotropic resonant scattering
A diffuse molecular gas can act collectively as a polarization-converting medium — turning linear into circular, rotating polarization angles, and even generating polarization out of light that arrives unpolarized.
-
Tracing the large-scale magnetic field morphology in protoplanetary disks using molecular line polarization
Which molecules give the cleanest read on the magnetic-field morphology of a planet-forming disk? High-dipole-moment species like HCN, especially in the dense inner regions.
-
Probing the electron-to-proton mass ratio gradient in the Milky Way with Class I methanol masers
A subtle test of fundamental physics — does the electron-to-proton mass ratio change across the Galaxy? — using methanol masers as exquisitely sensitive frequency standards.
-
Generalisation of the Menegozzi and Lamb maser algorithm to the transient superradiance regime
The most rigorous maser-modelling algorithm still misses the most extreme *transient superradiance* regime. Here is the generalisation that extends it — with the same rigor, and a manageable cost.
-
Collisional polarization of molecular ions: a signpost of ambipolar diffusion
A 70-year-old idea about how gas decouples from the magnetic field in collapsing clouds finally has a clean observational fingerprint — the polarization of molecular ions.
-
PORTAL: three-dimensional polarized (sub)millimeter line radiative transfer
A 3-D code that turns a model cube and a magnetic-field configuration into the polarized molecular-line maps that ALMA actually observes.
-
Characterizing maser polarization: effects of saturation, anisotropic pumping and hyperfine structure
A general code for the polarization of cosmic masers — the first to handle arbitrary saturation, hyperfine structure, and the non-Zeeman polarization signatures that confuse simpler models.
-
Stringent limits on the magnetic field strength in the disc of TW Hya
The first stringent upper limits on the magnetic field strength inside a planet-forming disk — too small for some accretion-disk models, just compatible with others.
-
Updated Zeeman effect splitting coefficients for molecular oxygen in planetary applications
A small piece of molecular physics with surprisingly broad reach — from satellite remote sensing of the Earth's atmosphere to the CMB foreground that atmospheric oxygen imprints on ground-based cosmology experiments.
-
Characterization of methanol as a magnetic field tracer in star-forming regions
A decade of methanol-maser observations toward massive star-forming regions becomes proper magnetic-field measurements once the molecule's quantum mechanics is finally pinned down.
-
Hyperfine interactions and internal rotation in methanol
A first-principles theory of methanol's hyperfine structure including the molecule's notorious internal rotation — the molecular-physics groundwork that later turned methanol masers into a quantitative magnetic-field diagnostic.
