Is the flow-aligned component of IMF really able to impact the magnetic field structure of Venusian magnetotail?
Barabash, S.; Futaana, Y.; Wei, Y. +5 more
An earlier statistical survey suggested that the flow-aligned component of upstream interplanetary magnetic field (IMF) may play an important role in controlling the lobe asymmetries of the Venusian magnetotail. The tail current sheet would be displaced and the magnetic field configuration would show asymmetries with respect to the current sheet. …
Maps of the Magellanic Clouds from Combined South Pole Telescope and PLANCK Data
Bleem, L. E.; Stark, A. A.; George, E. M. +39 more
We present maps of the Large and Small Magellanic Clouds from combined South Pole Telescope (SPT) and Planck data. The Planck satellite observes in nine bands, while the SPT data used in this work were taken with the three-band SPT-SZ camera, The SPT-SZ bands correspond closely to three of the nine Planck bands, namely those centered at 1.4, 2.1, …
The Role of Quenching Time in the Evolution of the Mass-size Relation of Passive Galaxies from the Wisp Survey
Zanella, A.; Scarlata, C.; Malkan, M. +13 more
We analyze how passive galaxies at z ∼ 1.5 populate the mass-size plane as a function of their stellar age, to understand if the observed size growth with time can be explained with the appearance of larger quenched galaxies at lower redshift. We use a sample of 32 passive galaxies extracted from the Wide Field Camera 3 Infrared Spectroscopic Para…
The 2015 hard-state only outburst of GS 1354-64
Stiele, H.; Kong, A. K. H.
Since its outburst in 1997, GS 1354-64 stayed in quiescence. In 2015 June, renewed activity of GS 1354-64 was observed. Based on our analysis of energy spectra and timing properties obtained from Swift/X-ray telescope monitoring data, we found that GS 1354-64 stayed in the hard state during the entire outburst. Such a hard state only (or `failed' …
Development of Active Regions: Flows, Magnetic-Field Patterns and Bordering Effect
Ishikawa, R.; Getling, A. V.; Buchnev, A. A.
A qualitative analysis is given of the data on the full magnetic and velocity vector fields in a growing sunspot group, recorded nearly simultaneously with the Solar Optical Telescope on the Hinode satellite. Observations of a young bipolar subregion developing within AR 11313 were carried out on 9 - 10 October 2011. Our aim was to form an idea ab…
Infrared and Ultraviolet Spectra of Methane Diluted in Solid Nitrogen and Irradiated with Electrons during Deposition at Various Temperatures
Chin, Chih-Hao; Chen, Sian-Cong; Liu, Meng-Chen +2 more
We recorded the infrared and ultraviolet absorption spectra of CH4:N2 matrix samples that underwent electron bombardment during deposition in the temperature range of 10-44 K. In contrast to a previous experiment on the IR spectroscopy of electron-bombarded icy samples, methyl and azide radicals became the main products upon …
In situ observations of waves in Venus's polar lower thermosphere with Venus Express aerobraking
Svedhem, Håkan; Bruinsma, Sean; Marty, Jean-Charles +1 more
The final stage of the Venus Express mission involved aerobraking — or deceleration by atmospheric drag — through the upper atmosphere above the northern pole of Venus. Concurrent measurements revealed two kinds of waves.
Major substructure in the M31 Outer Halo: the East Cloud
Mackey, A. D.; Martin, N. F.; Ferguson, A. M. N. +8 more
We present the first detailed analysis of the East Cloud, a highly disrupted diffuse stellar substructure in the outer halo of M31. The core of the substructure lies at a projected distance of ∼100 kpc from the centre of M31 in the outer halo, with possible extensions reaching right into the inner halo. Using Pan-Andromeda Archaeological Survey ph…
A new pattern in Saturn's D ring created in late 2011
Hedman, M. M.; Showalter, M. R.
Images obtained by the Cassini spacecraft between 2012 and 2015 reveal a periodic brightness variation in a region of Saturn's D ring that previously appeared to be rather featureless. Furthermore, the intensity and radial wavenumber of this pattern have decreased steadily with time since it was first observed. Based on analogies with similar stru…
A Search for Very Low-luminosity Objects in Gould Belt Clouds
Kim, Gwanjeong; Kim, Mi-Ryang; Lee, Chang Won +3 more
We present the results of a search for Very Low-Luminosity Objects (VeLLOs) in the Gould Belt (GB) clouds using infrared and sub-millimeter (sub-mm) data from 1.25 to 850 µm and our {{{N}}}2{{{H}}}+ (J = 1-0) observations. We modified the criteria by Dunham et al. to select the VeLLOs in the GB clouds, finding 95 VeLLO …
