Sources of Pressure in Titan's Plasma Environment
N. Achilleos, C. S. Arridge, C. Bertucci +3
In order to analyze varying plasma conditions upstream of Titan, we have combined a physical model of Saturn's plasmadisk with a geometrical model of the oscillating current sheet.…
The Spitzer-South Pole Telescope Deep Field: Survey Design and IRAC Catalogs
M. L. N. Ashby, S. A. Stanford, M. Brodwin +18
The Spitzer-South Pole Telescope Deep Field (SSDF) is a wide-area survey using Spitzer's Infrared Array Camera (IRAC) to cover 94 square degrees of extragalactic sky, making it the…
HERschel Observations of Edge-on Spirals (HEROES). I: Far-infrared morphology and dust mass determination
J. Verstappen, J. Fritz, M. Baes +11
Context. Edge-on spiral galaxies with prominent dust lanes provide us with an excellent opportunity to study the distribution and properties of the dust within them. The HEROES pro…
Experimental Neutron-Induced Fission Fragment Mass Yields of 232Th and 238U at Energies from 10 to 33 MeV
V. D. Simutkin, S. Pomp, J. Blomgren +9
Development of nuclear energy applications requires data for neutron-induced reactions for actinides in a wide neutron energy range. Here we describe measurements of pre-neutron em…
On the relative distance of Magellanic Clouds using Cepheid NlR and Optical-NIR PW relations
L. Inno, G. Bono, N. Matsunaga +8
We present new estimates of the relative distance of the Magellanic Clouds (MCs) by using NIR and Optical-NIR Cepheid Period Wesenheit (PW) relations. The relative distances are in…
What determines the density structure of molecular clouds ? A case study of Orion B with Herschel
N. Schneider, Ph. Andre, V. Konyves +19
A key parameter to the description of all star formation processes is the density structure of the gas. In this letter, we make use of probability distribution functions (PDFs) of…
Disk dynamics and the X-ray emission of S0 and flat early-type galaxies
Andrea Negri, Silvia Pellegrini, Luca Ciotti
With 2D hydrodynamical simulations, we study the evolution of the hot gas flows in early-type galaxies, focussing on the effects of galaxy rotation on the thermal and dynamical sta…
The effects of flattening and rotation on the temperature of the X-ray halos of elliptical galaxies
Silvia Posacki, Silvia Pellegrini, Luca Ciotti
Elliptical galaxies have hot coronae with X-ray luminosities and mean gas temperatures that span over wide ranges. This variation can be partially due to the energy budget of the h…
LOFAR detections of low-frequency radio recombination lines towards Cassiopeia A
Ashish Asgekar, J. B. R. Oonk, S. Yatawatta +89
Cassiopeia A was observed using the Low-Band Antennas of the LOw Frequency ARray (LOFAR) with high spectral resolution. This allowed a search for radio recombination lines (RRLs) a…
On the distance of the Magellanic Clouds using Cepheid NIR and optical-NIR Period Wesenheit Relations
L. Inno, N. Matsunaga, G. Bono +8
We present the largest near-infrared (NIR) data sets, , ever collected for classical Cepheids in the Magellanic Clouds (MCs). We selected fundamental (FU) and first overtone…
Constraints on mass loss of globular clusters in dwarf galaxies
S. S. Larsen, J. Strader, J. P. Brodie
The Fornax dwarf spheroidal galaxy is well known for its very high globular cluster specific frequency, SN=26. Furthermore, while the field star metallicity distribution peaks at […
