Ultraviolet C II and Si III Transit Spectroscopy and Modeling of the Evaporating Atmosphere of GJ436b
R. O. Parke Loyd, T. T. Koskinen, Kevin France +2
Hydrogen gas evaporating from the atmosphere of the hot-Neptune GJ436b absorbs over 50% of the stellar Ly emission during transit. Given the planet's atmospheric composition and…
Velocity Segregation and Systematic Biases In Velocity Dispersion Estimates With the SPT-GMOS Spectroscopic Survey
Matthew. B. Bayliss, Kyle Zengo, Jonathan Ruel +15
The velocity distribution of galaxies in clusters is not universal; rather, galaxies are segregated according to their spectral type and relative luminosity. We examine the velocit…
Finding the UV-Visible Path Forward: Proceedings of the Community Workshop to Plan the Future of UV/Visible Space Astrophysics
Paul A. Scowen, Todd Tripp, Matt Beasley +30
We present the science cases and technological discussions that came from the workshop entitled "Finding the UV-Visible Path Forward" held at NASA GSFC June 25-26, 2015. The materi…
Detection of thermal radio emission from a single coronal giant
Eamon O'Gorman, Graham M. Harper, Wouter Vlemmings
We report the detection of thermal continuum radio emission from the K0 III coronal giant Pollux ( Gem) with the Karl G. Jansky Very Large Array (VLA). The star was detected at…
Convective heat transport in stratified atmospheres at low and high Mach number
Evan H. Anders, Benjamin P. Brown
We study fully compressible convection in the context of plane-parallel, polytropically stratified atmospheres. We perform a suite of 2D and 3D simulations in which we vary the ini…
Analytic solution of an oscillatory migratory alpha^2 stellar dynamo
Axel Brandenburg
Analytic solutions of the mean-field induction equation predict a nonoscillatory dynamo for homogeneous helical turbulence or constant alpha effect in unbounded or periodic domains…
The Puzzling Detection of X-rays From Pluto by Chandra
C. M. Lisse, R. L. McNutt, S. J. Wolk +17
Using Chandra ACIS-S, we have obtained imaging Xray spectrophotometry of the Pluto system in support of the New Horizons flyby on 14 July 2015. 174 ksec of observations were obtain…
Improved Measurement of the Spectral Index of the Diffuse Radio Background Between 90 and 190 MHz
Thomas. J. Mozdzen, Judd. D. Bowman, Raul. A. Monsalve +1
We report absolutely calibrated measurements of diffuse radio emission between 90 and 190 MHz from the Experiment to Detect the Global EoR Signature (EDGES). EDGES employs a wide b…
The time evolution of HH~2 from four epochs of HST images
A. C. Raga, B. Reipurth, P. F. Velázquez +2
We have analyzed four epochs of H and [S~II] HST images of the HH~1/2 outflow (covering a time interval from 1994 to 2014) to determine proper motions and emission line fluxes o…
Constraining the ISM properties of the Cloverleaf quasar host galaxy with Herschel spectroscopy
Bade D. Uzgil, C. Matt Bradford, Steve Hailey-Dunsheath +2
We present Herschel observations of far-infrared (FIR) fine-structure (FS) lines [CII]158m, [OI]63m, [OIII]52m, and [SiII]35m in the z=2.56 Cloverleaf quasar, and combi…
The Role of Host Galaxy for the Environmental Dependence of Active Nuclei in Local Galaxies
R. I. Davies, E. K. S. Hicks, P. Erwin +22
We discuss the environment of local hard X-ray selected active galaxies, with reference to two independent group catalogues. We find that the fraction of these AGN in S0 host galax…
Enhancement of small-scale turbulent dynamo by large-scale shear
Nishant K. Singh, Igor Rogachevskii, Axel Brandenburg
Small-scale dynamos are ubiquitous in a broad range of turbulent flows with large-scale shear, ranging from solar and galactic magnetism to accretion disks, cosmology and structure…
Two-scale analysis of solar magnetic helicity
Axel Brandenburg, Gordon J. D. Petrie, Nishant K. Singh
We develop a two-scale formalism to determine global magnetic helicity spectra in systems where the local magnetic helicity has opposite signs on both sides of the equator, giving…
Magnetic concentrations in stratified turbulence: the negative effective magnetic pressure instability
Axel Brandenburg, Igor Rogachevskii, Nathan Kleeorin
In the presence of strong density stratification, hydromagnetic turbulence attains qualitatively new properties: the formation of magnetic flux concentrations. We review here the t…
Scale-invariant helical magnetic field evolution and the duration of inflation
Tina Kahniashvili, Axel Brandenburg, Ruth Durrer +2
We consider a scale-invariant helical magnetic field generated during inflation. We show that, if the mean magnetic helicity density of such a field is measured, it can be used to…
Coronal Dynamic Activities in the Declining Phase of a Solar Cycle
Minhwan Jang, T. N. Woods, Sunhak Hong +1
It has been known that some solar activity indicators show a double-peak feature in their evolution through a solar cycle, which is not conspicuous in sunspot number. In this lette…
gPhoton: The GALEX Photon Data Archive
Chase Million, Scott W. Fleming, Bernie Shiao +6
gPhoton is a new database product and software package that enables analysis of GALEX ultraviolet data at the photon level. The project's stand-alone, pure-Python calibration pipel…
SPIRITS 15c and SPIRITS 14buu: Two Obscured Supernovae in the Nearby Star-Forming Galaxy IC 2163
Jacob E. Jencson, Mansi M. Kasliwal, Joel Johansson +22
SPIRITS---SPitzer InfraRed Intensive Transients Survey---is an ongoing survey of nearby galaxies searching for infrared (IR) transients with Spitzer/IRAC. We present the discovery…
Three-dimensional distribution of ejecta in Supernova 1987A at 10 000 days
