Title The Light of the Night Sky Type Book Whole
Year 1973 Publication Abbreviated Journal
Volume Issue Pages
Keywords Natural Sky Brightness; Airglow
Abstract (up) Astronomy appears to us as a combination of art, science, and philosophy. Its study puts the universe into perspective, giving a sense of pleasure in its beauty, awe at its immensity, and humility at our trivial place in it. From earliest human history, man has scrutinized the night sky – and wondered and marveled. With unaided eye but perceptive mind, he recognized order in the regular appearance and movements of individual objects, such as the planets and star groups (constellations), in their rhythmic and majestic progressions across the bowl of night. Even in the present era of scientific exactitude, there remains a profound awareness of mysteries beyond our present interpretations. It is only in comparatively recent years, however, that man has recognized that it takes more than conventional astronomy to account for the beauties ofthe night sky. Radiations in the Earth's upper atmosphere provide a foreground light, the study of which has come under a new name, aeronomy. The science of aeronomy has rapidly burgeoned, and the student of the light of the night sky finds that he is involved in an interdisciplinary domain. The 'meat' of one discipline, however, may be the 'poison' of the other. To the astronomer, the Earth's atmosphere, inhibiting his extra-terrestrial viewing, is a serious nuisance. To the aeronomer, the Moon, planets, stars, and Galaxies hamper his measurements and interfere with his studies of the Earth's upper atmosphere. Yet both sets of elements are basic to the beauties as well as to the understanding of the light of the night sky. It is essentially the students of astronomy and aeronomy for whom we have written this book. We also hope, however, that it will present much of interest and value to the bemused sky watcher, for whom some detailed knowledge of the several con-tried to meld these dual objectives to create a broadly based, professionally valid tributors to the nighttinie sky may increase his pleasure in contemplating it. We have treatise that will lead the serious student to deeper probing into the phenomena and will inspire both him and the enthusiastic amateur to an appreciation of that half of their experience which we may refer to as their 'night life'.

Title The Possible Potentials of Astrotourism in Caucasus Type Journal Article
Year 2020 Publication Communications of the Byurakan Astrophysical Observatory Abbreviated Journal
Volume 67 Issue 1 Pages 127-132
Keywords Astrotourism
Abstract (up) Astrotourism is not a new topic, but it is certainly a title that has been in the forefront of tourismand astronomy for less than two decades. For nearly half a century, observatories and sciencecenters have been opening their doors to the public on special occasions, such as Astronomy Day.However, for less than a decade, astrotourism has been the constant presence of tourists alongsideprofessional astronomers, especially on weekends. They have made it possible by following allthe principles. Until the early 1990s, one of the most important countries in the world to hostthe world's largest astronomical observatories was the Soviet Union. The Caucasus region in theformer Soviet Union hosted very important observatories due to its high altitudes, pure nature, andvery low amount of light pollution and, of course, the proper weather in warm seasons. Byurakanin Armenia, Abastumani in Georgia, Shamakhi in Azerbaijan, and BTA-6 in Russia are the fourmain collections left from that period. Fortunately, nearly two decades after the independenceof the countries in the region, the restoration and updating of these observatories have been onthe agenda. One of the helping arms to accelerate the revival of these observatories is to takeadvantage of the potential of astrotourism; especially with the location of these three countriesnear Iran, which has one of the largest astronomy enthusiast communities in the region.

Title Habitat type, food resources, noise and light pollution explain the species composition, abundance and stability of a winter bird assemblage in an urban environment Type Journal Article
Year 2017 Publication Urban Ecosystems Abbreviated Journal Urban Ecosyst
Volume 20 Issue 3 Pages 547-559
Keywords Animals
Abstract (up) At present, urban areas cover almost 3% of the Earth’s terrestrial area, and this proportion is constantly increasing. Although urbanization leads to a decline in biodiversity, at the same time it creates extensive habitats that are exploited by an assemblage of organisms, including birds. The species composition and density of birds nesting in towns and cities are determined by the types of buildings, the structure and maturity of urban greenery, and habitat diversity. In contrast, the habitat traits shaping the community of birds wintering in urban areas are not known. The aim of this work was to assess the influence of habitat structure, food resources and the urban effects (pollution, noise, artificial light) on an assemblage of birds overwintering in an urban area. It was carried out in 2014 and 2015 in the city of Kraków (southern Poland), on 56 randomly chosen sample plots, in which the composition, density and interseasonal similarity of bird assemblage were assessed with line transect method. A total of 64 bird species (mean = 17.7 ± 4.9 SD species/plot) was recorded. The mean density was 89.6 ind./km ±63.3 SD. The most numerous species were Great Tit Parus major, Magpie Pica pica, Blackbird Turdus merula, Blue Tit Cyanistes caeruleus, Rook Corvus frugilegus, Fieldfare Turdus pilaris and House Sparrow Passer domesticus. Noise adversely affected species numbers and density, but artificial light acted positively on the density of birds and their interseasonal stability. The species richness and density of birds were also determined by the number of food sources available (e.g. bird-feeders). In addition, the greater the proportion of open areas, the fewer species were recorded. In contrast, the more urban greenery there was, the greater the density of the entire bird assemblage. Urban infrastructure (buildings, roads, refuse tips) had a positive effect on the interseasonal stabilization of the species composition of wintering birds. The results of this work indicate that the urban effect, i.e. noise and light pollution, apart from purely habitat factors, provide a good explanation for the species richness, density and stability of bird assemblage wintering in urban areas.

Title On the feasibility of using ceilometer backscatter profile as input data for skyglow simulation Type Journal Article
Year 2020 Publication Journal of Quantitative Spectroscopy and Radiative Transfer Abbreviated Journal Journal of Quantitative Spectroscopy and Radiative Transfer
Volume in press Issue Pages in press
Keywords Skyglow; Instrumentation
Abstract (up) Atmospheric conditions can significantly affect the sky brightness originating from artificial lights. Previous works studied the cloudiness, cloud base height, optical depth of cloud, aerosol optical depth and aerosol scale height as atmospheric parameters affecting night sky brightness. Instead of using these parameters as a simplification of the real cloud and aerosol profile, we processed the raw backscatter data of a laser ceilometer instrument. Sky brightness was obtained from camera images available at the same meteorological observation site. Case studies are shown in selected cases, where we analyzed the correspondences with the backscatter data and the camera images. We performed Monte Carlo simulations with the dominant light sources to verify the numerical predictions of sky radiances. Although the limitations of the ceilometer device to obtain optical properties of the atmosphere, ceilometers provide valuable source of data for evaluation of the light pollution measurements.

Title Patterns of wild carnivore attacks on humans in urban areas Type Journal Article
Year 2018 Publication Scientific Reports Abbreviated Journal Sci Rep
Volume 8 Issue 1 Pages
Keywords Animals
Abstract (up) Attacks by wild carnivores on humans represent an increasing problem in urban areas across North America and their frequency is expected to rise following urban expansion towards carnivore habitats. Here, we analyzed records of carnivore attacks on humans in urban areas of the U.S. and Canada between 1980 and 2016 to analyze the general patterns of the attacks, as well as describe the landscape structure and, for those attacks occurring at night, the light conditions at the site of the attacks. We found that several behavioral and landscape-related factors were recurrent elements in the attacks recorded. The species for which the attack locations were available (coyote and black bear) attacked in areas with different conditions of landscape structure and artificial light. Specifically, black bears attacked more frequently in areas with abundant and aggregated vegetation cover and scarce buildings and roads, while coyotes attacked in a broader range of landscape conditions. At night, black bears attacked in generally darker areas than coyotes. By providing a comprehensive perspective of the phenomenon, this study will improve our understanding of how effective strategies aimed at reducing the frequency of risky encounters in urban areas should be developed.
