Characterizing the Circumgalactic Medium of Nearby Galaxies with HST/COS and HST/STIS Absorption-Line Spectroscopy
John T. Stocke, Brian A. Keeney, Charles W. Danforth +5
The Circumgalactic Medium (CGM) of late-type galaxies is characterized using UV spectroscopy of 11 targeted QSO/galaxy pairs at z < 0.02 with the Hubble Space Telescope Cosmic Orig…
WR 120bb and WR 120bc: a pair of WN9h stars with possibly interacting circumstellar shells
Sonja Burgemeister, Vasilii V. Gvaramadze, Guy S. Stringfellow +3
Two optically obscured Wolf-Rayet (WR) stars have been recently discovered by means of their infrared (IR) circumstellar shells, which show signatures of interaction with each othe…
Variability of Solar Five-Minute Oscillations in the Corona as Observed by the Extreme Ultraviolet Spectrophotometer (ESP) on the Solar Dynamics Observatory Extreme Ultraviolet Variability Experiment (SDO/EVE)
Leonid Didkovsky, Alexander Kosovichev, Darrell Judge +2
Solar five-minute oscillations have been detected in the power spectra of two six-day time intervals from soft X-ray measurements of the Sun observed as a star using the Extreme Ul…
The LOFAR radio environment
A. R. Offringa, A. G. de Bruyn, S. Zaroubi +93
Aims: This paper discusses the spectral occupancy for performing radio astronomy with the Low-Frequency Array (LOFAR), with a focus on imaging observations. Methods: We have analys…
A multilayer model for thermal infrared emission of Saturn's rings. III: Thermal inertia inferred from Cassini CIRS
Ryuji Morishima, Linda Spilker, Keiji Ohtsuki
The thermal inertia values of Saturn's main rings (the A, B, and C rings and the Cassini division) are derived by applying our thermal model to azimuthally scanned spectra taken by…
The Scale of the Problem : Recovering Images of Reionization with GMCA
Emma Chapman, Filipe B. Abdalla, J. Bobin +8
The accurate and precise removal of 21-cm foregrounds from Epoch of Reionization redshifted 21-cm emission data is essential if we are to gain insight into an unexplored cosmologic…
On the Significance of Absorption Features in HST/COS Data
Brian A. Keeney, Charles W. Danforth, John T. Stocke +2
We present empirical scaling relations for the significance of absorption features detected in medium resolution, far-UV spectra obtained with the Cosmic Origins Spectrograph (COS)…
Precision Measurement of The Most Distant Spectroscopically Confirmed Supernova Ia with the Hubble Space Telescope
D. Rubin, R. A. Knop, E. Rykoff +25
We report the discovery of a redshift 1.71 supernova in the GOODS North field. The Hubble Space Telescope (HST) ACS spectrum has almost negligible contamination from the host or ne…
Time-resolved Ultraviolet Spectroscopy of the M-dwarf GJ 876 Exoplanetary System
Kevin France, Jeffrey L. Linsky, Feng Tian +2
Extrasolar planets orbiting M-stars may represent our best chance to discover habitable worlds in the coming decade. The ultraviolet spectrum incident upon both Earth-like and Jovi…
Long-time properties of MHD turbulence and the role of symmetries
Joshua E. Stawarz, Annick Pouquet, Marc-Etienne Brachet
We investigate long-time properties of three-dimensional MHD turbulence in the absence of forcing and examine in particular the role played by the quadratic invariants of the syste…
The roles of charge exchange and dissociation in spreading Saturn's neutral clouds
B. L. Fleshman, P. A. Delamere, F. Bagenal +1
Neutrals sourced directly from Enceladus's plumes are initially confined to a dense neutral torus in Enceladus's orbit around Saturn. This neutral torus is redistributed by charge…
A 3D view of the outflow in the Orion Molecular Cloud 1 (OMC-1)
H. D. Nissen, N. J. Cunningham, M. Gustafsson +4
The fast outflow emerging from a region associated with massive star formation in the Orion Molecular Cloud 1 (OMC-1), located behind the Orion Nebula, appears to have been set in…
Three dimensional density cavities in guide field collisionless magnetic reconnection
Stefano Markidis, Giovanni Lapenta, Andrey Divin +3
Particle-in-Cell simulations of collisionless magnetic reconnection with a guide field reveal for the first time the three dimensional features of the low density regions along the…
Collisionless magnetic reconnection in a plasmoid chain
Stefano Markidis, Pierre Henri, Giovanni Lapenta +4
The kinetic features of plasmoid chain formation and evolution are investigated by two dimensional Particle-in-Cell simulations. Magnetic reconnection is initiated in multiple X po…
Observations of Enhanced EUV Continua During An X-Class Solar Flare Using SDO/EVE
Ryan O. Milligan, Phillip C. Chamberlin, Hugh S. Hudson +5
Observations of extreme-ultraviolet (EUV) emission from an X-class solar flare that occurred on 2011 February 15 at 01:44 UT are presented, obtained using the EUV Variability Exper…
