Testing Gravitational Lensing as the Source of Enhanced Strong Mg II Absorption toward Gamma-Ray Bursts
Schmidt, Brian P.; Onken, Christopher A.; Tucker, Brad E. +3 more
Sixty percent of gamma-ray bursts (GRBs) reveal strong Mg II absorbing systems, which is a factor of ~2 times the rate seen along lines of sight to quasars. Previous studies argue that the discrepancy in the strong Mg II covering factor is most likely to be the result of either quasars being obscured due to dust or the consequence of many GRBs bei…

Far-infrared Imaging Observations of the Chamaeleon Region
Takita, Satoshi; Kaneda, Hidehiro; Kawamura, Akiko +4 more
We have carried out far-infrared imaging observations toward the Chamaeleon star-forming region by the Far-Infrared Surveyor (FIS) on board the AKARI satellite. The AKARI images cover a total area of 33.79 deg2, corresponding to 210 pc2 at the distance to the source. Using the FIS bands of 65-160 µm and the COBE/DIRBE b…

Characteristics of DH type II bursts, CMEs and flares with respect to the acceleration of CMEs
Prakash, O.; Shanmugaraju, A.; Vršnak, Bojan +2 more
A detailed investigation on DH-type-II radio bursts recorded in Deca-Hectometer (hereinafter DH-type-II) wavelength range and their associated CMEs observed during the year 1997–2008 is presented. The sample of 212 DH-type-II associated with CMEs are classified into three populations: (i) Group I (43 events): DH-type-II associated CMEs are acceler…
Vertical cloud structure of the 2009 Jupiter impact based on HST/WFC3 observations
Sánchez-Lavega, A.; Pérez-Hoyos, S.; Wong, M. H. +7 more
The impact of a body of unknown origin with Jupiter in July 2009 produced an intense perturbation of the planet’s atmosphere at the visible cloud levels. The vertical cloud structure was deeply affected by the presence of a strongly absorbing dense aerosol layer that was expanded steadily by advection in the local winds. We observed this phenomeno…
XMM-Newton Observations of Two Candidate Supernova Remnants
Pavlov, G. G.; Kargaltsev, O.; Misanovic, Z. +1 more
Candidate supernova remnants (SNRs) G23.5+0.1 and G25.5+0.0 were observed by XMM-Newton in the course of a snapshot survey of plerionic and composite SNRs in the Galactic plane. In the field of G23.5+0.1, we detected an extended source, ~3' in diameter, which we tentatively interpret as a pulsar wind nebula (PWN) of the middle-aged radio pulsar B1…
The massive stellar population in the young association LH 95 in the Large Magellanic Cloud
Da Rio, N.; Gouliermis, D. A.; De Marchi, G. +3 more
We present a spectroscopic study of the most massive stars in the young (4 Myr old) stellar cluster LH 95 in the Large Magellanic Cloud. This analysis allows us to complete the census of the stellar population of the system, previously investigated by us down to 0.4 M⊙ with deep Hubble Space Telescope Advanced Camera for Surveys photome…
A Multi-spacecraft View of a Giant Filament Eruption during 2009 September 26/27
Gosain, Sanjay; Schmieder, Brigitte; Artzner, Guy +2 more
We analyze multi-spacecraft observations of a giant filament eruption that occurred during 2009 September 26 and 27. The filament eruption was associated with a relatively slow coronal mass ejection. The filament consisted of a large and a small part, and both parts erupted nearly simultaneously. Here we focus on the eruption associated with the l…
