[O II] emitters at z ∼ 4.6 in the GOODS field: a homogeneous measure of evolving star formation
Banerji, M.; McMahon, R. G.; Venemans, B. P. +2 more
We present the results of a high-redshift, z = 4.6, survey of [O II] λ3727 emission line galaxies in the GOODS-S field. The survey uses deep near-infrared data in the NB2090 (λc = 2.095 µm, Δ λ = 0.02 µm) and Ks (λc = 2.146 µm, Δ λ = 0.324 µm) filters taken with the European Southern Observatory instru…
Energetic Particles Measured in and out of the Ecliptic Plane During the Last Gnevyshev Gap
Rodríguez-Pacheco, J.; Gómez-Herrero, R.; Heber, B. +1 more
We analyzed the temporal variation of energetic particles measured by the Low Energy Telescope (LET), the Kiel Electron Telescope (KET), and the High Energy Telescope (HET) instruments aboard Ulysses and the Electron Proton Helium Instrument (EPHIN) aboard SOHO during the last solar magnetic field polarity reversal in 2001. We have found two perio…
Interpretation of the coronal magnetic field configuration of the Sun
Li, Xing; Li, Bo; Yu, Hui
The origin of the heliospheric magnetic flux on the Sun, and hence the origin of the solar wind, is a topic of hot debate. While the prevailing view is that the solar wind originates from outside the coronal streamer helmets, there also exists the suggestion that the open magnetic field spans a far wider region. Without the definitive measurement …
Analysing the Suzaku spectra of the broad-line Seyfert 1 galaxy CBS 126
Fabian, A. C.; Reis, R. C.; Grupe, D. +2 more
We analysed new simultaneous Suzaku and Swift data of the broad-line Seyfert 1 (BLS1) galaxy CBS 126. A clear Fe emission line and a strong soft excess are present in the source spectra. We fit the spectra with a relativistic reflection model and find that the model tends to fit the data with a high iron abundance possibly due to the large soft ex…
First Orbit and Mass Determinations for Nine Visual Binaries
Ling, J. F.
This paper presents the first published orbits and masses for nine visual double stars: WDS 00149-3209 (B 1024), WDS 01006+4719 (MAD 1), WDS 03130+4417 (STT 51), WDS 04357+3944 (HU 1084), WDS 19083+2706 (HO 98 AB), WDS 19222-0735 (A 102 AB), WDS 20524+2008 (HO 144), WDS 21051+0757 (HDS 3004 AB), and WDS 22202+2931 (BU 1216). Masses were calculated…
The cusp as a source of magnetospheric particles
Chen, J.; Fritz, T. A.; Walsh, B. M. +1 more
Observations made by a number of satellites have shown that plasma of solar wind/magnetosheath origin enters the high altitude polar cusp creating diamagnetic cavities of large dimensions. The Earth's dipole field can be excluded from this region in a turbulent manner with the magnitude of the field strength reaching close to 0 nT at times. In the…
Solar cycle and latitude dependence of high-beta suprathermal plasma conditions in interplanetary space between 1.3 and 5.4 AU
Marhavilas, Panagiotis K.
The analysis of energetic particles and magnetic field measurements from the Ulysses spacecraft has shown that in a series of events, the energy density contained in the suprathermal tail particle distribution is comparable to or larger than that of the magnetic field, creating conditions of high-beta plasma. In this work we analyze periods of hig…
The search for high-mass X-ray binaries in the Phoenix dwarf galaxy
Haberl, F.; Bartlett, E. S.; Coe, M. J. +2 more
We report on the first X-ray images of the Phoenix dwarf galaxy, taken with XMM-Newton in 2009 July. This Local Group dwarf galaxy shares similarities with the Small Magellanic Cloud (SMC) including a burst of star formation ∼50 Myr ago. The SMC has an abundance of high-mass X-ray binaries (HMXBs) and so we have investigated the possibility of an …
Underlying structural control of small-scale faults and fractures in West Candor Chasma, Mars
Hauber, E.; Fueten, F.; Stesky, R. +1 more
Orientations of small-scale faults and fractures within the interior layered deposits of West Candor Chasma were measured to investigate what information about the geologic history of Valles Marineris they can contribute. Deformational features were separated into six categories based on morphology and their orientations were analyzed. The elevati…
Brightness and polarization opposition effects at low phase angles of the Saturnian satellites Tethys, Dione, and Rhea
Kulyk, Irina
The photometric and polarization phase dependences of the Saturnian moons Tethys, Dione, and Rhea are studied in a narrow domain of solar phase angles around opposition by using observations obtained with the 2-m RCC telescope of the National Astronomical Observatory at Rozhen, Bulgaria. The observations were made in the solar phase angle range fr…
