Features of the X-ray spectra of active galactic nuclei Mrk 1498

Vasylenko, A. A.; Fedorova, E. V.; Zhdanov, V. I.

We present results of our analysis of the XMM-Newton and Swift observations of the galaxy with Sy 1.9 active nucleus Mrk 1498. We analyze the spectra obtained from three EPIC cameras (PN and both MOS) within the 0.2-12 keV energy range and Swift/BAT instrument within the range of 14-195 keV. We demonstrate that for the X-ray spectrum of the AGN in…

Classification and disk parameters of Herbig Ae/Be stars using WISE and AKARI data

Subramaniam, Annapurni; Adara, B.

We present the classification and disk parameters of 50 Herbig Ae/Be stars using WISE and AKARI data. These stars have been classified into 4 groups based on the scheme proposed by Koenig et al. (2012) using WISE pass bands and by constructing their SEDs using data up to 12 pass bands. We could successfully classify 18 sources as Class I, 22 as Cl…

X-ray Emission from the Born-Again Planetary Nebula Abell 30

Guerrero, M. A.

The planetary nebula (PN) Abell 30 underwent a very late thermal pulse that resulted in the ejection of knots of hydrogen-poor material. ROSAT detected soft X-ray emission from these knots. We present deep Chandra and XMM-Newton observations that show this X-ray emission to consist of two components: a point-source at the central star and diffuse …

The brightness of comet 67P/Churyumov-Gerasimenko

Shanklin, J.

Comet Section records of 67P/Churyumov-Gerasimenko have been analysed to catalogue the comet's behaviour over previous visually observed apparitions. Predictions are made for future returns.

The ~10 hour modulation of the relativistic electron spectrum as a result of the periodic motion of the Jovian outer magnetosphere layer: Ulysses observations

Anagnostopoulos, G. C.; Karanikola, I.; Marhavilas, P. K.

We analyze relativistic (E>3 MeV) electron observations during the dayside inbound trajectory of Ulysses (day 33 to day 38, 1992) in the Jovian magnetosphere and we demonstrate that the continuous presence of a relativistic electron layer at higher north latitudes (Ulysses reached ~40° lat. during closest approach the planet). In particular, we…

Submillimetre photometry of 323 nearby galaxies from the Herschel Reference Survey (Corrigendum)

Clements, D. L.; Ciesla, L.; Buat, V. +23 more

Herschel is an ESA space observatory with science instruments provided by European-led Principal Investigator consortia and with important participation from NASA.

Pixel Level Data Fusion of Mars Express HRSC Linear Pushbroom Imagery Based on the Rigorous Geometric Model

Xun, G.; Qing, X.; Yuange, L. +3 more

The High Resolution Stereo Camera (HRSC) on European spacecraft Mars Express is especially designed for topographic mapping of Mars. HRSC can acquire both panchromatic and multi-spectral images simultaneously. The resolution of panchromatic image is higher than that of multi-spectral image. Through image fusion, the high resolution multi-spectral …

Metals in the Intracluster Medium of MS 1512.4+3647 Observed with Suzaku: Implications for the Metal Enrichment History

Sato, Kosuke; Tashiro, Makoto S.; Ohashi, Takaya +5 more

The cluster of galaxies MS 1512.4+3647 (z = 0.372) was observed with Suzaku for 270 ks. Besides the Fe abundance, the abundances of Mg, Si, S, and Ni were separately determined for the first time in a medium redshift cluster (z > 0.3). The derived abundance pattern of MS 1512.4+3647 is consistent with those of nearby clusters, suggesting that t…

The spatial distributions of the sources of UV solar Explosive Events at different velocities

Mendoza-Torres, J. E.

We analyze five solar Explosive Events observed in the Si IV emission line at 139.37 nm during SUMER/SoHO raster scans near disk center. The Doppler velocities from -45 km s^-1 to +45 km s^-1 were sorted into eleven symmetrically organized velocity bins, five equally-sized bins on each side and one bin for the line at rest. The…
