Evidence for Nonlinear Growth of Structure from an X-Ray-Selected Cluster Survey using a Novel Joint Analysis of the Chandra and XMM-Newton Archives

Kahn, S. M.; Peterson, J. R.; Gupta, R. R. +2 more

We present a large X-ray-selected serendipitous cluster survey based on a novel joint analysis of archival Chandra and XMM-Newton data. The survey provides enough depth to reach clusters of flux of ≈10^-14ergcm^-2s^-1 near z≈ 1 and simultaneously a large-enough sample to find evidence for the strong evolution of clust…

AKARI: space infrared cooled telescope

Onaka, Takashi; Salama, Alberto

AKARI, formerly known as ASTRO-F, is the second Japanese space mission to perform infrared astronomical observations. AKARI was launched on 21 February 2006 (UT) and brought into a sun-synchronous polar orbit at an altitude of 700 km by a JAXA M-V rocket. AKARI has a telescope with a primary-mirror aperture size of 685 mm together with two focal-p…

Calibration pipeline of VIS-NIR imaging spectrometers for planetary exploration: The rosetta VIRTIS-M case

Piccioni, Giuseppe; Filacchione, Gianrico; Capaccioni, Fabrizio +3 more

The capability of spaceborne VIS-NIR imaging spectrometers devoted to planetary exploration to acquire valuable scientific datasets largely depends on the accuracy of the calibration pipeline. In this paper we discuss about the method currently used to calibrate the flight data of VIRTISM (Visible InfraRed Thermal Imaging Spectrometer, Mapping Cha…

A study of the bound water, water ice, and frost distribution over the Martian surface: Treatment and correcting of the data of observations with the OMEGA spectrometer onboard Mars Express

Fedorova, A. A.; Kuzmin, R. O.; Rodin, A. V. +3 more

The results of the analysis of the spectral observations of Mars carried out with the OMEGA spectrometer onboard the Mars Express spacecraft are presented. The data from one of the spectrometer’s channels working in the near-IR spectral range (0.93-2.69 µm) were analyzed. This range includes the characteristic absorption bands of both condensed wa…

Multipoint observations of plasma distributions around an X line

Fazakerley, A. N.; Owen, C. J.; Nakamura, R. +9 more

Using electron and magnetic field data obtained from the Cluster satellites, we identify the spatial distribution of highly accelerated electron distributions up to 10 keV. They are generally isotropic and form flat-top distributions in the phase space. These distributions are observed in the vicinity of the X line associated with the quadrupole-l…

The role of lateral magnetic reconnection in solar eruptive events

Poedts, S.; Bemporad, A.; Soenen, A. +1 more

On 10-11 December 2005 a slow CME occurred in between two coronal streamers in the Western Hemisphere. SOHO/MDI magnetograms show a multipolar magnetic configuration at the photosphere consisting of a complex of active regions located at the CME source and two bipoles at the base of the lateral coronal streamers. White light observations reveal th…

Gamma-ray telescopes. 400 Years of astronomical telescopes

Gehrels, Neil; Cannizzo, John K.

The last half-century has seen dramatic developments in γ-ray telescopes, from their initial conception and development through to their blossoming into full maturity as a potent research tool in astronomy. Gamma-ray telescopes are leading research in diverse areas such as γ-ray bursts, blazars, Galactic transients, and the Galactic distribution o…

Statistical Study of the Solar Wind Deceleration in the Earth's Foreshock Region

Lucek, E.; Reme, H.; Cao, Jin-Bin +2 more

The data from two same satellites (CLUSTER C1 and C3) were used to make a statistical study of the solar wind deceleration and deflection in the Earth's foreshock region for the first time. In the foreshock coordinates, the magnitude of deceleration is inversely proportional to the distance DBS between the satellite and the bow shock along the int…
