The Gamma-Ray Emitting Radio-Loud Narrow-Line Seyfert 1 Galaxy PKS 2004-447 II. The Radio View
R. Schulz, A. Kreikenbohm, M. Kadler +20
Gamma-ray detected radio-loud narrow-line Seyfert 1 (g-NLS1) galaxies constitute a small but interesting sample of the gamma-ray loud AGN. The radio-loudest g-NLS1 known, PKS 2004-…
Deeply Virtual Meson Production on the nucleon
L. Favart, M. Guidal, T. Horn +1
We review the status of the data and phenomenology in the Generalized Parton Distribution approach of Deep Virtual Meson Production.
Target and Double Spin Asymmetries of Deeply Virtual Production with a Longitudinally Polarized Proton Target and CLAS

The target and double spin asymmetries of the exclusive pseudoscalar channel were measured for the first time in the deep-inelastic regime using a longitudi…
NuSTAR and XMM-Newton Observations of the Hard X-Ray Spectrum of Centaurus A
F. Fuerst, C. Mueller, K. K. Madsen +28
We present simultaneous XMM-Newton and NuSTAR observations spanning 3-78 keV of the nearest radio galaxy, Centaurus A (Cen A). The accretion geometry around the central engine in C…
Dust formation in the oxygen-rich AGB star IK Tau
D. Gobrecht, I. Cherchneff, A. Sarangi +2
We model the synthesis of molecules and dust in the inner wind of the oxygen-rich Mira-type star IK Tau, by considering the effects of periodic shocks induced by the stellar pulsat…
Evidence of thermal conduction suppression in hot coronal loops: Supplementary results
Tongjiang Wang, Leon Ofman, Xudong Sun +2
Slow magnetoacoustic waves were first detected in hot (6 MK) flare loops by the SOHO/SUMER spectrometer as Doppler shift oscillations in Fe XIX and Fe XXI lines. Recently, such…
Properties and Geoeffectiveness of Magnetic Clouds during Solar Cycles 23 and 24
N. Gopalswamy, S. Yashiro, H. Xie +2
We report on a study that compares the properties of magnetic clouds (MCs) during the first 73 months of solar cycles 23 and 24 in order to understand the weak geomagnetic activity…
Nonlinear MHD waves in a Prominence Foot
Leon Ofman, Kalman Knizhnik, Therese Kucera +1
We study nonlinear waves in a prominence foot using 2.5D MHD model motivated by recent high-resolution observations with Hinode/SOT in Ca~II emission of a prominence on October 10,…
Propagation of the 7 January 2014 CME and Resulting Geomagnetic Non-Event
M. L. Mays, B. J. Thompson, L. K. Jian +8
On 7 January 2014 an X1.2 flare and CME with a radial speed 2500 km s was observed from near an active region close to disk center. This led many forecasters to est…
