Science drivers and requirements for an Advanced Technology Large Aperture Space Telescope (ATLAST): implications for technology development and synergies with other future facilities
Galaxy Large-Aperture Space Telescope
2014/12/22
The Advanced Technology Large-Aperture Space Telescope (ATLAST) is a concept for an 8-meter to 16-meter UVOIR space observatory for launch in the 2025-2030 era. ATLAST will allow astronomers to answer...
We investigate the origin of the color-magnitude relation (CMR) observed in cluster galaxies by using a combination of a cosmological N-body simulation of a cluster of galaxies and a semi-analytic mod...
Longitudinal EAS-Development Studies in the Air-Shower Experiment KASCADE-Grande
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/10/13
A large area (128 m^2) Muon Tracking Detector (MTD), located within the KASCADE experiment, has been built with the aim to identify muons (E_mu > 0.8 GeV) and their directions in extensive air showers...
On the development of QPOs in Bondi-Hoyle accretion flows
High Energy Astrophysical Phenomena (astro-ph.HE) General Relativity and Quantum Cosmology (gr-qc)
2010/10/8
The numerical investigation of Bondi-Hoyle accretion onto a moving black hole has a long history, both in Newtonian and in general-relativistic physics. By performing new two-dimensional and general-r...
The depth of maximum shower development and its fluctuations: cosmic ray mass composition at E_0 >= 10^17 eV
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/10/6
We present new data on Cherenkov light observations obtained during the period 1994-2009, after a modernization of the Yakutsk EAS array. A complex analysis of $\xmax$ and its fluctuations $\sigma(\xm...
The index of scintillation measurement is a good parameter to compare different sites for image quality or ‘seeing’.We have developed a scintillometer, which is deployed on the high resolution SPAR te...
Long term time variability of cosmic rays and possible relevance to the development of life on Earth
cosmic rays lightning evolution
2010/2/27
An analysis is made of the manner in which the cosmic ray intensity at Earth has varied over its existence and its possible relevance to both the origin and the evolution of life. Much of the analysis...

UN World Economic Social Survey 2009 the Planet
2009/8/28
As negotiations for a new global agreement to address climate change enter the final stages before the Copenhagen Climate Change Conference this December, the United Nations is issuing a report on 1 S...
Development of a generalized scidar at UNAM。
The index of scintillation measurement is a good parameter to compare different sites for image quality or 'seeing'™.We have developed a scintillometer, which is deployed on the high resolution...
