121. Art or Science? Images of scientific research : Photography contestTanja Petrushevska, 2017, umetniško delo Opis: Looking at the pinking of a sky at sunset we see a delicate impressionist watercolor or rather the spectacular effect of the refraction of the sun on the particles of the atmosphere? Can the extraordinary geometries of the cubic lattices of a salt crystal be considered a perfect composition deserving of admiration like a cubist painting? All the "infinite forms, ever more beautiful and wonderful" of life, as defined by the famous naturalist Charles Darwin, are art or science?
The Art or Science photo contest? was born to emphasize the contamination between these two fields, only apparently distant, of human knowledge, exalting the beauty of scientific research and rewarding the photographic talent of those who work in science.
The 2017 edition of the competition, conceived and promoted by the University of Trieste and Immaginario Scientifico, has collected 116 images of students and scientists from universities and research institutions. Among these were selected 30 photos, exhibited from 18 to 23 September 2017 in Trieste, at Palazzo Costanzi, as part of the Trieste Next-Festival of Scientific Research.

126. iPTF Discoveries of Recent Core-Collapse SupernovaeFrancesco Taddia, Tanja Petrushevska, 2016, drugi sestavni deli Opis: Abstract
The intermediate Palomar Transient Factory (ATel #4807) reports the discovery and classification of the following core-collapse SNe. Our automated candidate vetting to distinguish a real astrophysical source (1.0) from bogus artifacts (0.0) is powered by three generations of machine learning algorithms: RB2 (Brink et al. 2013MNRAS.435.1047B), RB4 (Rebbapragada et al. 2015AAS...22543402R) and RB5 (Wozniak et al. 2013AAS...22143105W).

130. VizieR Online Data Catalog: Measured photometry of SN 2014J from HST (Amanullah+, 2014)R. Amanullah, Tanja Petrushevska, zaključena znanstvena zbirka raziskovalnih podatkov Opis: We obtained observations (Program DD-13621; PI: Goobar) of SN 2014J with HST in the four UV broadband filters F218W, F225W, F275W, and F336W for seven epochs using a total of seven HST orbits during Cycle 21. In addition to this we also obtained optical broad-, medium-, and narrowband photometry in filters F467M, F631N, and F845M for visits (1, 3) and optical broadband photometry using F438W, F555W, and F814W for the remaining five visits. All observations were obtained with the Wide-Field Camera-3 (WFC3) using the UVIS aperture UVIS2-C512C-SUB.
