A Model for the Origin of High Density in Loop-top X-ray Sources
Model Origin Density Loop-top X-ray Sources
2011/10/8
Super-hot looptop sources, detected in some large solar flares, are compact sources of HXR emission with spectra matching thermal electron populations exceeding 30 megakelvins. High observed emission ...
Velocity measurements for a solar active region fan loop from Hinode/EIS observations
Velocity measurements solar active region observations
2011/10/8
The velocity pattern of a fan loop structure within a solar active region over the temperature range 0.15-1.5 MK is derived using data from the EUV Imaging Spectrometer (EIS) on board the Hinode satel...
Observational test of inflation in loop quantum cosmology
cosmology of theories beyond the SM cosmological perturbation theory quantum cosmology quantum gravity phenomenology
2011/10/18
We study in detail the power spectra of scalar and tensor perturbations generated during inflation in loop quantum cosmology (LQC). After clarifying in a novel quantitative way how inverse-volume corr...
Inflationary observables in loop quantum cosmology
Cosmology of Theories beyond the SM Loop quantum gravity and cosmology
2010/11/16
The full set of cosmological observables coming from linear scalar and tensor perturbations of loop quantum cosmology is computed in the presence of inverse-volume corrections.
Sigmoid-to-Flux-Rope Transition Leading to A Loop-Like Coronal Mass Ejection
Sun flares—Sun Coronal mass ejections (CMEs)—Sun filaments prominences
2010/11/11
Sigmoids are one of the most important precursor structures for solar eruptions.In this Letter, we study a sigmoid eruption on 2010 August 1 with EUV data obtained by the Atmospheric Imaging Assembly ...
The cosmological perturbation theory in loop cosmology with holonomy corrections
cosmological perturbation loop cosmology
2010/3/18
In this paper we investigate the scalar mode of first-order metric perturbations over spatially flat FRW spacetime when the holonomy correction is taken into account in the semi-classical framework of...
