3XMM J185246.6+003317 as transient neutron star

DOI: 10.1002/asna.201412189 Bibcode: 2015AN....336..545H

Neuhäuser, R.; Hohle, M. M.; Hambaryan, V. +2 more

We performed an X-ray timing and spectral analysis of the variable source 3XMM J185246.6+003317 to investigate its physical nature. The data from all observations of 3XMM J185246.6+003317 conducted by XMM-Newton EPIC MOS1 and MOS2 with the same instrumental setup in 2004-2009 were reprocessed to form a homogenous data set of solar barycenter corre…

Focal lengths of Venus Monitoring Camera from limb locations

DOI: 10.1016/j.pss.2015.01.010 Bibcode: 2015P&SS..113..169L

Limaye, Sanjay S.; Roatsch, T.; Markiewicz, W. J. +3 more

The Venus Monitoring Camera (VMC) carried by European Space Agency's Venus Express orbiter (Svedhem et al., 2007) consists of four optical units, each with a separate filter casting an image on a single CCD (Markiewicz et al., 2007a, 2007b). The desire to capture as much of the planet in a single frame during the spacecraft's 24 h, 0.84 eccentrici…

Revisiting the cosmological bias due to local gravitational redshifts

DOI: 10.1103/PhysRevD.91.121301 Bibcode: 2015PhRvD..91l1301H

Huang, Zhiqi

A recent article by Wojtak et al. pointed out that the local gravitational redshift, despite its smallness (∼10^-5 ), can have a noticeable (∼1 %) systematic effect on our cosmological parameter measurements. The authors studied a few extended cosmological models (nonflat Λ CDM , w CDM , and w₀-w_aCDM ) with a mock s…

Physical Properties of a Pilot Sample of Spectroscopic Close Pair Galaxies at z ~ 2

DOI: 10.1088/0004-637X/808/2/160 Bibcode: 2015ApJ...808..160L

Shapley, Alice E.; Steidel, Charles C.; Law, David R. +1 more

We use Hubble Space Telescope Wide-field Camera 3 rest-frame optical imaging to select a pilot sample of star-forming galaxies in the redshift range z = 2.00-2.65 whose multi-component morphologies are consistent with expectations for major mergers. We follow up this sample of major merger candidates with Keck/NIRSPEC long-slit spectroscopy obtain…

Towards the automated geomorphometric extraction of talus slopes in Martian landscapes

DOI: 10.1016/j.pss.2014.11.019 Bibcode: 2015P&SS..105..148P

Podobnikar, Tomaž; Székely, Balázs

Terrestrial talus slopes are a common feature of mountainous environments. Their geomorphic form is determined by their being constituted of scree, or similar loose and often poorly sorted material. Martian talus slopes are governed by the different nature of the Martian environment, namely: weaker gravity, the wide availability of loose material,…

Thermal transport in Saturn's B ring inferred from Cassini CIRS

DOI: 10.1016/j.icarus.2015.01.002 Bibcode: 2015Icar..254..157P

Altobelli, Nicolas; Showalter, Mark; Pilorz, Stuart +1 more

We examine the heat budget of Saturn's B ring using all of the data from Cassini's Composite Infra Red Spectrometer (CIRS) taken during one Saturn season, together with a detailed numerical calculation of the incident flux. We find that at all times 30-40% of the energy incident on the sunlit side finds its way through the ring to be emitted on th…

Herschel Hi-GAL imaging of massive young stellar objects

DOI: 10.1093/mnras/stv401 Bibcode: 2015MNRAS.449.2784O

Pezzuto, S.; de Wit, W. -J.; Molinari, S. +5 more

We used Herschel Hi-GAL (Herschel infrared Galactic Plane survey) data to determine whether massive young stellar objects (MYSOs) are resolved at 70 µm and to study their envelope density distribution. Our analysis of three relatively isolated sources in the l = 30° and 59° Galactic fields show that the objects are partially resolved at 70 &…

Ten years of INTEGRAL observations of the hard X-ray emission from SGR 1900+14

DOI: 10.1051/0004-6361/201527029 Bibcode: 2015A&A...583A.113D

Götz, D.; Mereghetti, S.; Santangelo, A. +1 more

We exploited the high sensitivity of the INTEGRAL IBIS/ISGRI instrument to study the persistent hard X-ray emission of the soft gamma-ray repeater SGR 1900+14, based on ~11.6 Ms of archival data. The 22-150 keV INTEGRAL spectrum can be well fitted by a power law with photon index 1.9 ± 0.3 and flux F_x = (1.11 ± 0.17) × 10^-11 …

An X-ray characterization of the central region of the supernova remnant G332.5-5.6

DOI: 10.1051/0004-6361/201526699 Bibcode: 2015A&A...583A..84S

Miceli, M.; Combi, J. A.; García, F. +3 more

Aims: We present an X-ray analysis of the central region of supernova remnant (SNR) G332.5-5.6 through an exhaustive analysis of XMM-Netwon observations with complementary infrared observations. We characterize and discuss the origin of the observed X-ray morphology, which presents a peculiar plane edge over the west side of the central regio…
