Estimation of the sky radiance [PDF]
For the infrared prefilter model there was a need for testing the sky radiation and defining its fluctuations within the zone of neighborhood area for the current frame and tests of repeatability.

On-sky tests of sky-subtraction methods for fiber-fed spectrographs [PDF]
We present preliminary results on on-sky test of sky subtraction methods for fiber-fed spectrograph. Using dedicated observation with FLAMES/VLT in I-band, we have tested the accuracy of the sky subtraction for 4 sky subtraction methods: mean sky, closest sky, dual stare and cross-beam switching.

Image of Shamanic Cosmos in Cyprus Turkish Folktales / Kıbrıs Türk Masallarında Şamanistik Evren Tasavvuru [PDF]
From mythology to celestial religions, cosmos is conceived of three parts. These are the sky where good gods are in, the earth where people live in and the underworld where bad gods and spirits are in. The sky is made up seven, nine or seventeen layers

Skycorr: A general tool for spectroscopic sky subtraction [PDF]
Airglow emission lines, which dominate the optical-to-near-IR sky radiation, show strong, line-dependent variability on various time scales. Therefore, the subtraction of the sky background in the affected wavelength regime becomes a problem if plain sky spectra have to be taken at a different time as the astronomical data.

Deeply x-raying the high-energy sky [PDF]
All-sky explorations by Fermi-LAT have revolutionized our view of the gamma-ray sky. While its ongoing all-sky survey counts thousands of sources, essential issues related to the nature of unassociated sources call for sensitive all-sky surveys at hard X-ray energies that allow for their identification.
