Analyzing PAHs as a Tracer of Anomalous Microwave Emission Near the Galactic Plane Using the COSMOGLOBE DIRBE Reduction
Dylan M. Pare, David T. Chuss, Danielle Sponseller +2
The physical mechanism producing Anomalous Microwave Emission (AME) has been an unresolved puzzle for close to 30 years. One candidate mechanism is rotational emission from polycyc…
Statistical Analysis of PAHs as a Tracer of Anomalous Microwave Emission Using DIRBE Data
Danielle Sponseller, David T. Chuss, Brandon Hensley +1
We use archival data from the Diffuse Infrared Background Experiment (DIRBE) to map the polycyclic aromatic hydrocarbon (PAH) 3.3 m emission feature and analyze its correlation…
A Rotational Disruption Crisis for Zodiacal Dust
Kedron Silsbee, Brandon S. Hensley, Jamey R. Szalay +2
A systematic torque from anisotropic radiation can rapidly spin up irregular grains to the point of breakup. We apply the standard theory of rotational disruption from radiative to…
The Optical Extinction Law Depends on Magnetic Field Orientation: The - Relation
Brandon S. Hensley
For aspherical interstellar dust grains aligned with their short axes preferentially parallel to the local magnetic field, the amount of extinction per grain is larger when the mag…
Dust extinction-curve variation in the translucent interstellar medium is driven by PAH growth
Xiangyu Zhang, Brandon S. Hensley, Gregory M. Green
The first all-sky, high-resolution, 3D map of the optical extinction curve of the Milky Way (Zhang & Green 2024) revealed an unexpected steepening of the extinction curve in the mo…
The Metallicity Dependence of PAH Emission in Galaxies I: Insights from Deep Radial Spitzer Spectroscopy
Cory M. Whitcomb, J. -D. T. Smith, Karin Sandstrom +9
We use deep Spitzer mid-infrared spectroscopic maps of radial strips across three nearby galaxies with well-studied metallicity gradients (M101, NGC 628, and NGC 2403) to explore t…
Where's the Dust?: The Deepening Anomaly of Microwave Emission in NGC 4725 B
E. J. Murphy, B. S. Hensley, S. T. Linden +5
We present new Atacama Large Millimeter Array (ALMA) observations towards NGC 4725 B, a discrete, compact, optically-faint region within the star-forming disk of the nearby galaxy…
A Case Against Spinning PAHs as the Source of the Anomalous Microwave Emission
Brandon S. Hensley, B. T. Draine, Aaron M. Meisner
We employ an all-sky map of the anomalous microwave emission (AME) produced by component separation of the microwave sky to study correlations between the AME and Galactic dust pro…
