In-flight calibration of the Cluster PEACE sensors

DOI: 10.5194/gi-3-59-2014 Bibcode: 2014GI......3...59D

Wilson, R. J.; Fazakerley, A. N.; Watson, G. +6 more

The Plasma Electron and Current Experiment (PEACE) instruments operate on all four of the Cluster spacecraft and measure the 3-D velocity distribution of electrons in the energy range from 0.59 eV to 26.4 keV during each spacecraft spin. Pitch angle distributions and moments of the velocity distribution are also produced. As the mission has progre…

The loss-limited electron energy in SN 1006: Effects of the shock velocity and of the diffusion process

DOI: 10.1002/asna.201312027 Bibcode: 2014AN....335..252M

Miceli, M.; Bocchino, F.; Decourchelle, A. +3 more

The spectral shape of the synchrotron X-ray emission from SN 1006 reveals the fundamental role played by radiative losses in shaping the high-energy tail of the electron spectrum. We analyze data from the XMM-Newton SN 1006 Large Program and confirm that in both nonthermal limbs the loss-limited model correctly describes the observed spectra. We s…

Radio Continuum Sources associated with the HH 92 and HH 34 Jets

DOI: 10.48550/arXiv.1405.6638 Bibcode: 2014RMxAA..50..285R

Rodríguez, Luis F.; Reipurth, Bo; Chiang, Hsin-Fang

We present high angular resolution, high sensitivity 8.46 GHz (3.6 cm) radio continuum observations made toward the core of the HH 92 outflow with the Very Large Array in 2002-2003 and with the Expanded Very Large Array in 2011. We detect a group of three compact sources distributed in a region 2'' in extension and discuss their nature. We conclud…

Gaia Science Alerts and the Observing Facilities of the Serbian-Bulgarian Mini-Network Telescopes

DOI: 10.2298/SAJ1488085D Bibcode: 2014SerAJ.188...85D

Damljanovic, G.; Vince, O.; Boeva, S.

The astrometric European Space Agency (ESA) Gaia mission was launched in December 19, 2013. One of the tasks of the Gaia mission is production of an astrometric catalog of over one billion stars and more than 500000 extragalactic sources. The quasars (QSOs), as extragalactic sources and radio emitters, are active galactic nuclei objects (AGNs) who…

Reducing the tension between the BICEP2 and the Planck measurements: A complete exploration of the parameter space

DOI: 10.1016/j.physletb.2014.09.053 Bibcode: 2014PhLB..738..206L

Lu, You-Jun; Li, Yi-Chao; Wu, Feng-Quan +1 more

A large inflationary tensor-to-scalar ratio r_0.002 =0.20_-0.05^+0.07 is reported by the BICEP2 team based on their B-mode polarization detection, which is outside of the 95% confidence level of the Planck best fit model. We explore several possible ways to reduce the tension between the two by considering a model in …

Dynamical Behavior of X-Ray Spectra from Markarian 766

DOI: 10.1088/0004-637X/780/1/35 Bibcode: 2014ApJ...780...35L

Takahashi, M.; Liebmann, A. C.; Haba, Y. +3 more

Mrk 766, a bright narrow-line Seyfert 1, has been observed eight times by the XMM-Newton satellite. We carried out the analysis of the composite data from all of these observations together by applying a dynamical method. Through this analysis, we noted a longer timescale variability in addition to rapid short-time variability. This longer term va…

Distortion of the stellar velocity field parameters due to systematic variations of parallaxes over the celestial sphere

DOI: 10.1134/S1063773714010083 Bibcode: 2014AstL...40...46V

Tsvetkov, A. S.; Vityazev, V. V.

We study the effect of systematic variations in stellar parallaxes over the celestial sphere on the results of a kinematic analysis of stellar proper motions. Our approach is based on the representation of stellar parallaxes by scalar spherical harmonics and on the decomposition of stellar proper motions into a system of vector spherical harmonics…

Operations and performance of the PACS instrument ³He sorption cooler on board of the Herschel space observatory

DOI: 10.1007/s10686-014-9388-z Bibcode: 2014ExA....37..397S

Poglitsch, A.; Okumura, K.; Sauvage, M. +5 more

A ³He sorption cooler produced the operational temperature of 285 mK for the bolometer arrays of the Photodetector Array Camera and Spectrometer (PACS) instrument of the Herschel Space Observatory. This cooler provided a stable hold time between 60 and 73 h, depending on the operational conditions of the instrument. The respective hold …
