Remote visualization and analysis of extremely large scientific images.Īpplications of this work include survey image quality control, interactiveĭata query and exploration, citizen science, as well as public outreach. We present a high performance, versatile and robust client-server system for In terms of speed and ergonomics, especially on mobile devices. Location with current astronomy display tools can be a frustrating experience Visualizing and navigating through large astronomy images from a remote However, the mixing of Chandra imaging and spectroscopic data resulted on rare artifacts present on flux mosaics and loss on spectroscopic resolution preventing from doing strong asseverations regarding flaring periods on the seen variability. From the analyzed spectra, X-ray emission variability is again evident. Such behavior is coincident with the interpretation of the Fe Kα line emission as reprocessed, fluorescence, emission on gas clouds surrounding Sgr A⋆. Specifically, spectra corresponding to the years 20 showed an interesting characteristic of a delay on the variability of the background emission and the Fe Kα line emission. ![]() ![]() The spectra were extracted from the region in the immediate vicinity of Sgr A⋆. This line is an important probe of high-energy phenomena and it is a prevalent feature of different galactic center emissions. Additionally, spectral analysis was performed to model the Galactic Center emission and characterize it with the Fe Kα line variability. Such variability is better visualized if the three flux maps are put together on an RGB map which showed complex variations within molecular clouds. Particularly, the flux maps constructed on three different periods showed similar structures of molecular clouds found on previous works and the X-ray emission variability is evident as illumination patterns on the maps. Specifically, flux maps of the galactic central region were constructed to see the emission variability and its correlation to greater structures such as molecular clouds. Extensive observations towards the Galactic Center have revealed a rather faint emission (∼ 1039 erg/s) coming from Sgr A⋆ with a particular high variability on the X-ray band showing flaring activity. Sgr A⋆ and the Galactic Center are the best laboratories to study galactic nuclei high-energy phenomena as it is the closest (∼ 8 kpc) galactic nucleus allowing high-resolution observation runs. Sgr A⋆ is a compact radio source at the center of the Milky Way with strong evidence to be a supermassive black hole with a mass of about ∼ 4 × 106 M⊙. This work presents an X-ray study of the Sagittarius A⋆ (Sgr A⋆) emission variability on Chandra observations data during the years 2001 to 2017. ![]()
