Constraining the Magnetic Field of the Smith High Velocity Cloud using Faraday rotation
S. K. Betti, Alex S. Hill, S. A. Mao +4
The Smith Cloud is a high velocity cloud (HVC) with an orbit suggesting it has made at least one passage through the Milky Way disk. A magnetic field found around this cloud has be…
The Galactic Magneto-Ionic Medium Survey: Moments of the Faraday Spectra
John M. Dickey, T. L. Landecker, A. J. M. Thomson +11
Faraday rotation occurs along every line of sight in the Galaxy; Rotation Measure (RM) synthesis allows a three-dimensional representation of the interstellar magnetic field. This…
Wavelet Methods for Studying the Onset of Strong Plasma Turbulence
Ari Le, Vadim Roytershteyn, Homa Karimabadi +3
Wavelet basis functions are a natural tool for analyzing turbulent flows containing localized coherent structures of different spatial scales. Here, wavelets are used to study the…
Understanding the Limitations of Gyrochronology for Old Field Stars
Travis S. Metcalfe, Ricky Egeland
Nearly half a century has passed since the initial indications that stellar rotation slows while chromospheric activity weakens with a power-law dependence on age, the so-called Sk…
Identifying Young Stellar Objects in the Outer Galaxy: l = 224 deg Region in Canis Major
Marta Sewiło, Barbara A. Whitney, Bosco H. K. Yung +14
We study a very young star-forming region in the outer Galaxy that is the most concentrated source of outflows in the Spitzer Space Telescope GLIMPSE360 survey. This region, dubbed…
Is there a polarization horizon?
A. S. Hill
Modern radio spectrometers make measurement of polarized intensity as a function of Faraday depth possible. I investigate the effect of depolarization along a model line of sight.…
Imaging the disc rim and a moving close-in companion candidate in the pre-transitional disc of V1247 Orionis
Matthew Willson, Stefan Kraus, Jacques Kluska +17
V1247 Orionis harbours a pre-transitional disc with a partially cleared gap. Earlier interferometric and polarimetric observations revealed strong asymmetries both in the gap regio…
Probing the Inner Disk Emission of the Herbig Ae Stars HD 163296 and HD 190073
Benjamin R. Setterholm, John D. Monnier, Claire L. Davies +16
The physical processes occurring within the inner few astronomical units of proto-planetary disks surrounding Herbig Ae stars are crucial to setting the environment in which the ou…
BAT AGN Spectroscopic Survey - XI. The Covering Factor of Dust and Gas in Swift/BAT Active Galactic Nuclei
Kohei Ichikawa, Claudio Ricci, Yoshihiro Ueda +10
We quantify the luminosity contribution of active galactic nuclei (AGN) to the 12 m, mid-infrared (MIR; 5-38 m), and the total IR (5-1000 m) emission in the local AGN dete…
Electron Strahl and Halo Formation in the Solar Wind
Konstantinos Horaites, Stanislav Boldyrev, Mikhail V. Medvedev
We propose a kinetic model describing the formation of the strahl and halo electron populations in the solar wind. We demonstrate that the suprathermal electrons propagating from t…
Multi-epoch Direct Imaging and Time-Variable Scattered Light Morphology of the HD 163296 Protoplanetary Disk
Evan A. Rich, John P. Wisniewski, Thayne Currie +58
We present H-band polarized scattered light imagery and JHK high-contrast spectroscopy of the protoplanetary disk around HD 163296 observed with the HiCIAO and SCExAO/CHARIS instru…
Investigating the Covering Fraction Distribution of Swift/BAT AGN with X-ray and IR Observations

We present an analysis of a sample of 69 local obscured Swift/Burst Alert Telescope active galactic nuclei (AGNs) with X-ray spectra from NuSTAR and infrared (IR) spectral energy d…
Inertial Kinetic-Alfvén Turbulence
Vadim Roytershteyn, Stanislav Boldyrev, Gian Luca Delzanno +3
Recent observational and analytical studies suggested that a new regime of kinetic turbulence may exist in plasma environments with low electron beta (Chen and Boldyrev, 2017). Suc…
