The multiphase interstellar medium as a common origin for magnetic misalignment and TB parity violation
Andrea Bracco, Ari J. Cukierman, Raphael Skalidis +1
We present an original data analysis and a physical model that provide new insights into the origin of, and relationship between, two observables of the dusty, polarized Galaxy at…
Evidence for cloud-to-cloud variations in the ratio of polarized thermal dust emission to starlight polarization
Nidhi Mehandiratta, Georgia V. Panopoulou, Eirik Gjerløw +12
The correlation between optical starlight polarization and polarized thermal dust emission can be used to infer intrinsic dust properties. This correlation is quantified by the rat…
Investigating the role of magnetic fields in the formation and evolution of striations in interstellar clouds with PRIMA
Raphael Skalidis, Konstantinos Tassis, Aris Tritsis +1
Striations are diffuse, linear, quasi-periodic, and magnetized structures located in the outskirts of molecular clouds. These structures seem to play an important role during the e…
A three-step approach to reliably estimate magnetic field strengths in star-forming regions
Aristeidis Polychronakis, Aris Tritsis, Raphael Skalidis +1
The magnetic field is known to play a crucial role in star formation. Dust polarization is an effective tool for probing the morphology of the field, yet it does not directly trace…
The H2 Glow of a Quiescent Molecular Cloud Observed with JWST
Paul F. Goldsmith, Shengzhe Wang, Xin Wang +6
We report JWST MIRI/MRS observations of the H2 S(1) 17.04 micron transition in two regions in the boundary of the Taurus Molecular Cloud. The two regions, denoted Edge (near the re…
Challenges in constraining dust properties from starlight polarization
Raphael Skalidis
Dust polarization, which comes from the alignment of aspherical grains to magnetic fields, has been widely employed to study the interstellar medium (ISM) dust properties. The wave…
3D ISM structure challenges the Serkowski relation
Nikolaos Mandarakas, Konstantinos Tassis, Raphael Skalidis
The Serkowski relation is the cornerstone of studies of starlight polarization as a function of wavelength. Although empirical, its extensive use since its inception to describe po…
Polarized Light from Massive Protoclusters (POLIMAP). I. Dissecting the role of magnetic fields in the massive infrared dark cloud G28.37+0.07
C-Y Law, Jonathan C. Tan, Raphael Skalidis +11
Magnetic fields may play a crucial role in setting the initial conditions of massive star and star cluster formation. To investigate this, we report SOFIA-HAWC+ m observati…
Constraining the H2 column densities in the diffuse interstellar medium using dust extinction and HI data
Raphael Skalidis, Paul F. Goldsmith, Philip F. Hopkins +1
Carbon monoxide (CO) is a poor tracer of H in the diffuse interstellar medium (ISM), where most of the carbon is not incorporated into CO molecules unlike the situation at hi…
Synchrotron Signatures of Cosmic Ray Transport Physics in Galaxies
Sam B. Ponnada, Iryna S. Butsky, Raphael Skalidis +7
Cosmic rays (CRs) may drive outflows and alter the phase structure of the circumgalactic medium, with potentially important implications on galaxy formation. However, these effects…
Synchrotron Emission on FIRE: Equipartition Estimators of Magnetic Fields in Simulated Galaxies with Spectrally-Resolved Cosmic Rays
Sam B. Ponnada, Georgia V. Panopoulou, Iryna S. Butsky +7
Synchrotron emission is one of few observable tracers of galactic magnetic fields (\textbf{B}) and cosmic rays (CRs). Much of our understanding of \textbf{B} in galaxies comes from…
Starlight-polarization-based tomography of the magnetized interstellar medium: PASIPHAE's line-of-sight inversion method
V. Pelgrims, G. V. Panopoulou, K. Tassis +20
We present the first Bayesian method for tomographic decomposition of the plane-of-sky orientation of the magnetic field with the use of stellar polarimetry and distance. This stan…
Energy balance and Alfvén Mach numbers in compressible magnetohydrodynamic turbulence with a large-scale magnetic field
James R. Beattie, Mark R. Krumholz, Raphael Skalidis +5
Energy equipartition is a powerful theoretical tool for understanding astrophysical plasmas. It is invoked, for example, to measure magnetic fields in the interstellar medium (ISM)…
High-accuracy estimation of magnetic field strength in the interstellar medium from dust polarization
Raphael Skalidis, Konstantinos Tassis
Dust polarization is a powerful tool for studying the magnetic field properties in the interstellar medium (ISM). However, it does not provide a direct measurement of its strength.…
Extreme Starlight Polarization in a Region with Highly Polarized Dust Emission
