112. Studying TDEs in the era of LSSTKatja Bricman, Andreja Gomboc, 2019, objavljeni povzetek znanstvenega prispevka na konferenci Opis: The observing strategy with continuous scanning and large sky coverage of the upcoming ground-based Large Synoptic Survey Telescope (LSST) will make it a perfect tool in search of rare transients, such as Tidal Disruption Events (TDEs). Bright optical flares resulting from tidal disruption of stars by their host supermassive black hole (SMBH) can provide us with important information about the mass of the SMBH involved in the disruption and thus enable the study of quiescent SMBHs, which represent a large majority of SMBHs found in centres of galaxies. These types of transients are extremely rare, with only about few tens of candidates discovered so far. It is expected that the LSST will provide a large sample of new TDE light curves. Here we present simulations of TDE observations using an end-to-end LSST simulation framework. Based on the analysis of simulated light curves we estimate the number of TDEs with good quality light curves the LSST is expected to discover in 10 years of observations. In addition, we investigate whether TDEs observed by the LSST could be used to probe the SMBH mass distribution in the universe.

113. Observing TDEs in the era of LSSTKatja Bricman, 2019, objavljeni povzetek znanstvenega prispevka na konferenci Opis: The upcoming Large Synoptic Survey Telescope (LSST) will observe ~18000 square degrees of the Southern sky and is expected to discover thousands of transients every night due to its large coverage of the sky and its observing strategy. Being an exceptional transient hunter, we expect the LSST to increase the current observed sample of Tidal Disruption Events (TDEs) by a factor of ~1000 in 10 years of survey duration. TDEs are one of the only probes of dormant supermassive black holes in the Universe, and if their observed optical light curves are sampled frequently enough, TDEs can serve as indicators of SMBH mass. In this talk I will present our simulations of TDE observations with LSST, the resulting SMBH mass distributions of observed TDEs, and the efficiency of different proposed observing strategies of LSST in finding these rare transients.

114. TDEs with LSSTKatja Bricman, 2018, objavljeni povzetek znanstvenega prispevka na konferenci Opis: The Large Synoptic Survey Telescope (LSST) is an upcoming ground-based survey telescope in Chile, which will produce a multi-color survey of 18000 square degrees of the Southern Sky during its 10 years of observations. Due to its large coverage of the sky and its observing strategy it will be a perfect tool in search for transient astrophysical events, including rare Tidal Disruption Events (TDEs). TDEs occur when a star passes close by a supermassive black hole (SMBH) in a center of a galaxy and gets disrupted by its tidal forces. These events emit a bright flare of light, which can be observed to cosmological distances.
In the seminar I will provide an overview of the LSST and TDEs, and present the preliminary results on the estimated absolute rates of TDE detection in 10 years of LSST operations, which were obtained by simulations of TDE light curves with an end-to-end LSST simulations framework.

117. Zofka Kveder as a Cultural TransmitterKatja Mihurko, 2020, izvirni znanstveni članek Opis: The article presents the forms and ways in which the cultural transmission of Zofka Kveder took place. It explains in which cultural spaces she worked and how she established personal contacts with artists. Zofka Kveder worked in a multidirectional way, as she promoted Slovene culture in the new cultural environments she moved into, and acquainted the Slovene cultural space with the achievements of foreign artists. She was also a mediator of ideas: feminism, Yugoslavism, and ideas about coexistence and mutual respect between different cultures. Zofka Kveder's translation oeuvre is very rich and almost unexplored so far, which opens up possibilities for new research.

119. Digitalizacija kulturne dediščine v dveh projektih programa Študentski inovativni projekti za družbeno korist : digitalizacija, korespondence, elektronske zbirke, aleksandrinke, študentski projekt, digitalna humanistikaKatja Mihurko, Narvika Bovcon, Aneta Ivanovska, Tina Smrekar, 2020, objavljeni znanstveni prispevek na konferenci Opis: Članek predstavi dva projekta digitalizacije in spletne predstavitve kulturne dediščine aleksandrink in različnih skupin žensk, ki so
večinsko povezane s primorskim in notranjskim geografskim prostorom: v prvem primeru gre za bazo podatkov o aleksandrinkah, v
drugem pa za digitalizirano pisemsko dediščino. Program Študentskih inovativnih projektov za družbeno korist je odlična platforma za
pilotske projekte s področja digitalne humanistike, saj predvideva interdisciplinarno delovno skupino študentov in mentorjev ter v
korist lokalne skupnosti usmerjene praktične rezultate projekta.
