Photospheric supergranular flows and magnetic flux emergence
Stangalini, M.
A recent study carried out on high-sensitivity SUNRISE/IMAX data has reported about areas of limited flux emergence in the quiet Sun. By exploiting an independent and longer (four hours) data set acquired by Hinode/SOT, we investigate these regions in more detail by analysing their spatial distribution and relation with the supergranular flow. Our…
The Phobos geodetic control point network and rotation model
Oberst, J.; Zubarev, A.; Nadezhdina, I. +2 more
A new global control point network was derived for Phobos, based on SRC (Mars Express), Phobos-2, and Viking Orbiter image data. We derive 3-D Cartesian coordinates for 813 control points as well as improved pointing data for 202 SRC and Viking images in the Phobos-fixed coordinate system. The point accuracies vary from 4.5 m on the Phobos nearsid…
NuSTAR and INTEGRAL Observations of a Low/Hard State of 1E1740.7-2942
Hailey, Charles J.; Fürst, Felix; Pottschmidt, Katja +19 more
The microquasar 1E1740.7-2942, also known as the "Great Annihilator," was observed by NuSTAR in the summer of 2012. We have analyzed in detail two observations taken ~2 weeks apart, for which we measure hard and smooth spectra typical of the low/hard state. A few weeks later the source flux declined significantly. Nearly simultaneous coverage by I…
Warped DGP model in warm intermediate inflation with a general dissipative coefficient in light of BICEP2 and Planck results
Videla, Nelson; Herrera, Ramón; Olivares, Marco
A warm inflationary universe scenario on a warped Dvali-Gabadadze-Porrati brane during intermediate inflation is studied. We consider a general form for the dissipative coefficient Γ (T ,ϕ )∝Tm/ϕm -1 , and also study this model in the weak and strong dissipative regimes. We analyze the evolution of the Universe in the slow-ro…
The local standard of rest from data on young objects with account for the Galactic spiral density wave
Bobylev, V. V.; Bajkova, A. T.
To estimate the peculiar velocity of the Sun with respect to the local standard of rest (LSR), we used young objects in the Solar neighbourhood with distance measurement errors within 10-15 per cent. These objects were the nearest Hipparcos stars of spectral classes O-B2.5, masers with trigonometric parallaxes measured by means of very long baseli…
Middle to Late Amazonian tropical mountain glaciers on Mars: The ages of the Tharsis Montes fan-shaped deposits
Head, James W.; Kadish, Seth J.; Fastook, James L. +1 more
Fan-shaped deposits (FSDs) extending to the northwest of the Tharsis Montes on Mars are the remnants of Amazonian-aged, cold-based, tropical mountain glaciers. We use high-resolution images to perform new impact crater size-frequency distribution (CSFD) analyses on these deposits in an effort to constrain the timing and duration of ice accumulatio…
Flapping current sheet with superposed waves seen in space and on the ground
Zhang, T. L.; Nakamura, R.; Volwerk, M. +4 more
A wavy current sheet event observed on 15 October 2004 between 1235 and 1300 UT has been studied by using Cluster and ground-based magnetometer data. Waves propagating from the tail center to the duskside flank with a period ~30 s and wavelength ~1 RE are superimposed on a flapping current sheet, accompanied with a bursty bulk flow. Thr…
Recombining Plasma in the Gamma-Ray-emitting Mixed-morphology Supernova Remnant 3C 391
Ercan, E. N.; Chatterjee, A.; Majumdar, P. +4 more
A group of middle-aged mixed-morphology (MM) supernova remnants (SNRs) interacting with molecular clouds (MCs) has been discovered to be strong GeV gamma-ray emitters by the Large Area Telescope (LAT) on board the Fermi Gamma-Ray Space Telescope (Fermi-LAT). The recent observations of the Suzaku X-ray satellite have revealed that some of these int…
No shock across part of a radio relic in the merging galaxy cluster ZwCl 2341.1+0000?
Simionescu, A.; van Weeren, R. J.; Brüggen, M. +2 more
The galaxy cluster ZwCl 2341.1+0000 is a merging system at z = 0.27, which hosts two radio relics and a central, faint, filamentary radio structure. The two radio relics have unusually flat integrated spectral indices of -0.49 ± 0.18 and -0.76 ± 0.17, values that cannot be easily reconciled with the theory of standard diffusive shock acceleration …
Linelist of HD16O for study of atmosphere of terrestrial planets (Earth, Venus and Mars)
Fedorova, A. A.; Lavrentieva, N. N.; Voronin, B. A. +2 more
Studies of water vapor in the atmospheres of Venus, Mars and Earth by spectroscopic techniques are being made routinely with different instruments on board of interplanetary missions like Mars-Express, Venus-Express and many others as well as with a lot of spacecrafts on the Earth’ orbit. Accessibility of detailed spectroscopic information in a wi…
