The width of Herschel filaments varies with distance
G. V. Panopoulou, S. E. Clark, A. Hacar +5
Context: Filamentary structures in nearby molecular clouds have been found to exhibit a characteristic width of 0.1 pc, as observed in dust emission. Understanding the origin of th…
Improved Galactic Foreground Removal for B-Modes Detection with Clustering Methods
Giuseppe Puglisi, Gueorgui Mihaylov, Georgia V. Panopoulou +4
Characterizing the sub-mm Galactic emission has become increasingly critical especially in identifying and removing its polarized contribution from the one emitted by the Cosmic Mi…
HI-H transition: exploring the role of the magnetic field
R. Skalidis, K. Tassis, G. V. Panopoulou +6
Atomic gas in the diffuse interstellar medium (ISM) is organized in filamentary structures. These structures usually host cold and dense molecular clumps. The Galactic magnetic fie…
First Predicted Cosmic Ray Spectra, Primary-to-Secondary Ratios, and Ionization Rates from MHD Galaxy Formation Simulations
Philip F. Hopkins, Iryna S. Butsky, Georgia V. Panopoulou +4
We present the first simulations evolving resolved spectra of cosmic rays (CRs) from MeV-TeV energies (including electrons, positrons, (anti)protons, and heavier nuclei), in live k…
Dust in the Wind with Resonant Drag Instabilities: I. The Dynamics of Dust-Driven Outflows in GMCs and HII Regions
Philip F. Hopkins, Anna L. Rosen, Jonathan Squire +4
Radiation-dust driven outflows, where radiation pressure on dust grains accelerates gas, occur in many astrophysical environments. Almost all previous numerical studies of these sy…
Revisiting the distance to radio Loops I and IV using Gaia and radio/optical polarization data
G. V. Panopoulou, C. Dickinson, A. C. S. Readhead +2
Galactic synchrotron emission exhibits large-angular-scale features known as radio spurs and loops. Determining the physical size of these structures is important for understanding…
The Time-Dependent Distribution of Optical Polarization Angle Changes in Blazars
S. Kiehlmann, D. Blinov, I. Liodakis +17
At optical wavelengths, blazar Electric Vector Position Angle (EVPA) rotations linked with gamma-ray activity have been the subject of intense interest and systematic investigation…
WALOP-South: A wide-field one-shot linear optical polarimeter for PASIPHAE survey
Siddharth Maharana, John A. Kypriotakis, A. N. Ramaprakash +20
WALOP (Wide-Area Linear Optical Polarimeter)-South, to be mounted on the 1m SAAO telescope in South Africa, is first of the two WALOP instruments currently under development for ca…
WALOP-South: A Four Camera One Shot Imaging Polarimeter for PASIPHAE Survey. Paper I -- Optical Design
Siddharth Maharana, John A. Kypriotakis, A. N. Ramaprakash +17
The WALOP-South instrument will be mounted on the 1 m SAAO telescope in South Africa as part of the PASIPHAE program to carry out a linear imaging polarization survey of the Galact…
Evidence for Line-of-Sight Frequency Decorrelation of Polarized Dust Emission in Data
V. Pelgrims, S. E. Clark, B. S. Hensley +5
If a single line of sight (LOS) intercepts multiple dust clouds of different spectral energy distributions and magnetic field orientations, the frequency scaling of each of the Sto…
