Study: Without more data, a black hole’s origins can be “spun” in any direction（图）
黑洞 双星系统 黑洞起源
2023/6/9
Clues to a black hole’s origins can be found in the way it spins. This is especially true for binaries, in which two black holes circle close together before merging. The spin and tilt of the respecti...
The Dark Energy Survey is now in its third year of capturing eye-popping images of the cosmos with its primary instrument, the Dark Energy Camera. Before the survey proper began in August 20...
New data from Antarctic detector firms up cosmic neutrino sighting
Antarctic detector cosmic neutrino
2015/9/9
This photo illustration shows one of the highest-energy neutrino events of this study superimposed on a view of the IceCube Lab (ICL) at the South Pole. Evidence of the neutrinos heralds a new form of...
Atomic data for neutron-capture elements II. Photoionization and recombination properties of low-charge krypton ions
atomic data - atomic processes - HII regions - nucleosynthesis, abundances - planetary nebulae: general - stars:evolution
2011/10/12
We present multi-configuration Breit-Pauli distorted-wave photoionization (PI) cross sections and radiative recombination (RR) and dielectronic recombination (DR) rate coefficients for the first six k...
Global fits of the cMSSM including the first LHC and XENON100 data
Global fits cMSSM including first LHC XENON100 data
2011/10/18
We present updated global fits of the constrained Minimal Supersymmetric Standard Model (cMSSM), including the most recent constraints from the ATLAS and CMS detectors at the LHC, as well as the most ...
CMS: Cosmic muons in simulation and measured data
CMS Cosmic muons simulation measured data
2011/10/18
A dedicated cosmic muon Monte-Carlo event generator CMSCGEN has been developed for the CMS experiment. The simulation relies on parameterisations of the muon energy and the incidence angle, based on m...
A fast 2D image reconstruction algorithm from 1D data for the Gaia mission
methods data analysis
2011/8/24
A fast 2-dimensional image reconstruction method is presented, which takes as input 1-dimensional data acquired from scans across a central source in different orientations. The resultant reconstructe...
Data Acquisition System for the UFFO Pathfinder
Gamma-Ray Bursts, data acquisition, interface
2011/9/14
The Ultra-Fast Flash Observatory (UFFO) Pathfinder is a payload on the Russian Lomonosov satellite, scheduled to be launched in November 2011. The Observatory is designed to detect early UV/Optical ph...
Consequences of the LHC Results in the Interpretation of gamma ray families and Giant EAS Data
the LHC Results the Interpretation
2011/1/13
The earliest results of CMS exhibit central pseudo rapidity densities larger than the predictions of the different models. Introducing on this basis new guidelines with larger multiplicities of secon...
The first release of data from the Herschel ATLAS: the SPIRE images
the Herschel ATLAS the SPIRE images
2011/1/11
We have reduced the data taken with the Spectral and Photometric Imaging Receiver (SPIRE) photometer on board the Herschel Space Observatory in the Science Demonstration Phase (SDP) of the Herschel As...
Plaskett's Star: Analysis of the CoRoT photometric data
Plaskett's Star the CoRoT photometric data
2011/1/10
The SRa02 of the CoRoT space mission for Asteroseismology was partly devoted to stars belonging to the Mon OB2 association. An intense monitoring was performed on Plaskett's Star (HD47129) and the unp...
The clustering of massive galaxies at z~0.5 from the first semester of BOSS data
massive galaxies the first semester of BOSS data
2011/1/10
We calculate the real- and redshift-space clustering of massive galaxies at z~0.5 using the first semester of data by the Baryon Oscillation Spectroscopic Survey (BOSS). We study the correlation funct...

Efficient data management is a key component in achieving good performance for scientific workflows in distributed environments. Workflow applications typically communicate data between tasks using fi...
Detecting and distinguishing topological defects in future data from the CMBPol satellite
distinguishing topological defects the CMBPol satellite
2011/1/11
The proposed CMBPol mission will be able to detect the imprint of topological defects on the cosmic microwave background (CMB) provided the contribution is sufficiently strong. We quantify the detecti...
Long-term lightcurves from combined unified very high energy $\gamma$-ray data
Long-term lightcurves combined unified
2011/1/11
Very high-energy (VHE, E\,$>$\,100\,GeV) $\gamma$-ray data are a valuable input for multi-wavelength and multi-messenger (e.g. combination with neutrino data) studies. We aim at the conservation and h...
