A “beautiful effect” predicted by quantum electrodynamics (QED) can explain the puzzling first observations of polarized X-rays emitted by a magnetar – a neutron star featuring a powerful magnetic fie...
Transition Radiation from the Neutrino-Photon Interaction in Matter
Transition Radiation the Neutrino-Photon Interaction Matter
2012/2/23
We show that, because of their effective electromagnetic interaction in matter, transition radiation is emitted whenever neutrinos goes across the boundary between two media with different indices of ...
Maximum-likelihood reconstruction of photon returns from simultaneous analog and photon-counting lidar measurements
Maximum-likelihood reconstruction photon returns simultaneous analog photon-counting lidar
2011/10/18
We present a novel method for combining the analog and photon-counting measurements of lidar transient recorders into reconstructed photon returns. The method takes into account the statistical proper...
Photon noise limited radiation detection with lens-antenna coupled Microwave Kinetic Inductance Detectors
Photon noise limited radiation Microwave Kinetic Inductance Detectors
2011/10/13
Microwave Kinetic Inductance Detectors (MKIDs) have shown great potential for sub-mm instrumentation because of the high scalability of the technology. Here we demonstrate for the first time in the su...
Effect of Dust on Lyman-alpha Photon Transfer in Optically Thick Halo
Effect Photon Transfe Optically Thick
2011/9/30
We investigate the effects of dust on Ly{\alpha} photons emergent from an optically thick medium by solving the integro-differential equation of the radiative transfer of resonant photons. To solve th...
Homochirality through Photon-Induced Melting of RNA/DNA: the Thermodynamic Dissipation Theory of the Origin of Life
Homochirality Photon-Induced Melting RNA/DNA
2011/1/13
The homochirality of the molecules of life has been a vexing problem with no generally accepted solution to date. Since a racemic mixture of chiral nucleotides frustrates the extension and replication...
Photon spectra from quark generation by WIMPs
Dark matter indirect searches WIMPs photon spectra and quark pairs annihilation
2010/11/16
If the present dark matter (DM) in the Universe annihilates into Standard Model (SM)particles, it must contribute to the gamma ray fluxes that are detected on the Earth. The magnitude of such contribu...
Instruments of RT-2 Experiment onboard CORONAS-PHOTON and their test and evaluation I: Ground calibration of RT-2/S and RT-2/G
Scintillation detectors · X
2010/11/16
Phoswich detectors (RT-2/S & RT-2/G) are major scientific payloads of the RT-2 Experiment onboard the CORONAS-PHOTON mission, which was launched into a polar Low Earth Orbit of around 550 km on 2009 J...
Simultaneous solution of Kompaneets equation and Radiative Transfer equation in the photon energy range 1 - 125 KeV
Diffuse radiation'Kompaneets equation radiative transfer X-rays
2010/11/12
Radiative transfer equation in plane parallel geometry and Kompaneets equa-tion is solved simultaneously to obtain theoretical spectrum of 1-125 KeV photon energy range. Diffuse radiation field is cal...
STUDY OF COMPTON BROADENING DUE TO ELECTRON-PHOTON SCATTERING
Stars: atmospheres Radiative transfer Scattering
2010/10/29
We have investigated the effects of Compton broadening due to
electron-photon scattering in hot stellar atmospheres. A purely electron-photon
scattering media is assumed to have plane parallel geome...
