Improved iterative reconstruction method for Compton imaging using median filter.

PLoS ONE, 2020
A Compton camera is a device for imaging a radio-source distribution without using a mechanical collimator. Ordered-subset expectation-maximization (OS-EM) is widely used to reconstruct Compton images.

Optical issues for the diagnostic stations for the ELI-NP compton gamma source [PDF]

, 2017
A high brightness electron Linac is being built in the Compton Gamma Source at the ELI Nuclear Physics facility in Romania. To achieve the design luminosity, a train of 32 bunches, 16 ns spaced, with a nominal charge of 250 pC will collide with the laser

X-ray reflection in the nearby Seyfert 2 galaxy NGC 1068

, 2006
We use the full broad-band XMM-Newton EPIC data to examine the X-ray spectrum of the nearby Seyfert 2 galaxy NGC 1068, previously shown to be complex with the X-ray continuum being a sum of components reflected/scattered from cold (neutral) and warm ...

High-resolution tSZ cartography of clusters of galaxies with NIKA at the IRAM 30-m telescope

, 2015
The thermal Sunyaev-Zeldovich effect (tSZ) is a powerful probe to study clusters of galaxies and is complementary with respect to X-ray, lensing or optical observations.

Analysis of the weighted conical Radon transform

Journal of Physics Communications
In this article, we consider the weighted conical Radon transform—the transform is motivated by Compton camera imaging as well as optical tomography. Our contribution involves introducing new inversion formulas for the weighted conical Radon transform ...
