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...
UNH scientist: Cosmic rays threaten future deep-space astronaut missions（图）
Cosmic rays astronauts
2014/12/1
DURHAM, N.H. –- Crewed missions to Mars remain an essential goal for NASA, but scientists are only now beginning to understand and characterize the radiation hazards that could make such ventures risk...
Future constraints on variations of the fine structure constant from combined CMB and weak lensing measurements
Future constraints variations fine structure constant combined CMB weak lensing measurements
2012/2/21
We forecast the ability of future CMB and galaxy lensing surveys to constrain variations of the fine structure constant. We found that lensing data, as those expected from satellite experiments as Euc...
Search for Individual Ultrahigh Energy Cosmic Ray Sources in the Future Data
ultra-high energy cosmic rays magnetic fi elds Galaxy
2011/10/8
We propose a new way to detect individual bright Ultra-High Energy Cosmic Ray (UHECR) sources above background if the Galactic Magnetic Field (GMF) gives the main contribution to UHECR deflections. Th...
Testing model independent modified gravity with future large scale surveys
Testing model independent modified gravity future large scale surveys
2011/9/27
Model-independent parametrisations of modified gravity have attracted a lot of attention over the past few years and numerous combinations of experiments and observables have been suggested to constra...
Future deceleration due to effect of event horizon on cosmic backreaction
Future deceleration cosmic backreaction
2011/1/10
The present acceleration of the universe leads to the formation of a cosmological future event horizon. We explore the effects of the event horizon on cosmological backreaction due to inhomogeneities ...
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...
Future CMB Constraints on Early, Cold, or Stressed Dark Energy
Future CMB Constraints on Early Cold Stressed Dark Energy
2011/1/11
We investigate future constraints on early dark energy (EDE) achievable by the Planck and CMBPol experiments, including cosmic microwave background (CMB) lensing. For the dark energy, we include the p...

Optimizing future experimental probes of inflation
2010/11/9
The discovery of many novel realizations of the in ationary universe paradigm has led to a degeneracy problem: many di erent in ationary Lagrangians generate the same perturbation spectra.Resolving th...
Planetary Nebula Surveys: Past, Present and Future
Stars post-AGB – planetary nebulae general – surveys general
2010/11/10
In this review we cover the detection, identification and astrophysical importance of planetary nebulae (PN). The legacy of the historic Perek & Kohoutek and Acker et al. catalogues is briefly covered...
Radio Halos and the importance of future observations at low frequency
Radio Halos future observations low frequency
2010/11/11
Radio observations discovered large scale non thermal sources in the central Mpc regions of
dynamically disturbed galaxy clusters (radio halos). The morphological and spectral properties of these sou...

2011/1/7
The Atacama Large Millimeter/submillimeter Array (ALMA), presently under construction, is a revolutionary astronomical interferometer, that will operate at (sub)millimeter wavelengths. With unpreceden...
Acoustic particle detection - from early ideas to future benefits
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/5
The history of acoustic neutrino detection technology is shortly reviewed from first ideas 50 years ago to the detailed R&D programs of the last decade. The physics potential of ultra-high energy neut...
