Mass distribution in an assembling super galaxy group at z = 0.37
Tran, Kim-Vy H.; Schrabback, Tim; Moustakas, John +4 more
Aims: We present a weak gravitational lensing analysis of supergroup SG1120-1202, consisting of four distinct X-ray-luminous groups that will merge to form a cluster comparable in mass to Coma at z = 0. These groups lie within a projected separation of 1 to 4 Mpc and within Δv = 550 km s-1 and form a unique protocluster to study th…
Determination of fundamental asteroseismic parameters using the Hilbert transform
Roth, Markus; Schad, Ariane; Kiefer, René +1 more
Context. Solar-like oscillations exhibit a regular pattern of frequencies. This pattern is dominated by the small and large frequency separations between modes. The accurate determination of these parameters is of great interest, because they give information about e.g. the evolutionary state and the mass of a star.
Aims: We want to develop a…

Water in star-forming regions with Herschel (WISH) (Corrigendum). V. The physical conditions in low-mass protostellar outflows revealed by multi-transition water observations
Liseau, R.; van Dishoeck, E. F.; Bergin, E. A. +17 more
Herschel is an ESA space observatory with science instruments provided by European-led Principal Investigator consortia and with important participation from NASA.
Herschel-HIFI observations of H2O, NH3, and N2H+ toward high-mass starless and protostellar clumps identified by the Hi-GAL survey⋆
Codella, C.; Persson, C. M.; Olmi, L.
Context. Our present understanding of high-mass star formation still remains very schematic. In particular, it is not yet clear how much of the difference between low-mass and high-mass star formation occurs during the earliest star formation phases.
Aims: The chemical characteristics of massive cold clumps, and the comparison with those of t…
Comet C/2013 A1 (Siding Spring) as seen with the Herschel Space Observatory
Marton, G.; Müller, T. G.; Kidger, M. +2 more
The thermal emission of comet C/2013 A1 (Siding Spring) was observed on March 31, 2013, at a heliocentric distance of 6.48 au using the PACS photometer camera of the Herschel Space Observatory. The comet was clearly active, showing a coma that could be traced to a distance of ~10'', i.e. ~50 000 km. Analysis of the radial intensity profiles of the…

On the origin of two unidentified radio/X-ray sources discovered with XMM-Newton
García, Federico; Combi, Jorge A.; Romero, Gustavo E. +1 more
Aims: We aim at clarifying the nature of the emission of two spatially related unidentified X-ray sources detected with XMM-Newton telescope at intermediate-low Galactic latitude
Methods: We use the imaging and spectral capabilities of XMM-Newton to study the X-ray properties of these two sources. In addition, we complement our study wit…
