1. Probing extreme environments with the Cherenkov Telescope ArrayC. Boisson, Anthony M. Brown, A. Burtovoi, M. Cerruti, M. Chernyakova, T. Hassan, J.-P. Lenain, Marina Manganaro, Serguei Vorobiov, Danilo Zavrtanik, 2021, drugi sestavni deli Opis: The physics of the non-thermal Universe provides information on the acceleration mechanisms in extreme environments, such as black holes and relativistic jets, neutron stars, supernovae or clusters of galaxies. In the presence of magnetic fields, particles can be accelerated towards relativistic energies. As a consequence, radiation along the entire electromagnetic spectrum can be observed, and extreme environments are also the most likely sources of multi-messenger emission. The most energetic part of the electromagnetic spectrum corresponds to the very-high-energy (VHE, E>100 GeV) gamma-ray regime, which can be extensively studied with ground based Imaging Atmospheric Cherenkov Telescopes (IACTs). The results obtained by the current generation of IACTs, such as H.E.S.S., MAGIC, and VERITAS, demonstrate the crucial importance of the VHE band in understanding the non-thermal emission of extreme environments in our Universe. In some objects, the energy output in gamma rays can even outshine the rest of the broadband spectrum. The Cherenkov Telescope Array (CTA) is the next generation of IACTs, which, with cutting edge technology and a strategic configuration of ~100 telescopes distributed in two observing sites, in the northern and southern hemispheres, will reach better sensitivity, angular and energy resolution, and broader energy coverage than currently operational IACTs. With CTA we can probe the most extreme environments and considerably boost our knowledge of the non-thermal Universe.

2. Kratek zgodovinski pregled izseljevanja iz Črne gore in sedanji odnos do diaspore : diplomsko deloSvetozar Bastać, 2024, diplomsko delo Opis: Diplomsko je sestavljeno iz teoretičnega dela, v katerem sem ugotovil, kaj migracije sploh so. Prvi del diplomskega dela je posvečen kompleksnemu teoretskemu, sociološkemu in zgodovinskemu pristopu k migracijam, skozi katerega so predstavljeni teorija migracij, migracijska periodika, koncept migranta ter znanstvene discipline, ki se ukvarjajo s to tematiko. Po teoretičnem delu so v diplomskem delu predstavljena migracijska gibanja z ozemlja današnje Črne gore od najstarejših ohranjenih zapisov, preko množičnega izseljevanja v drugi polovici 19. in prvi polovici 20. stoletja do načrtne naselitve Vojvodine po drugi svetovni vojni. Poudarek dela je tudi na interpretaciji manj znanih kulturnih drobcev iz življenja izseljencev, kot so prve organizacije in vpliv kulturnih razlik, s katerimi so se prvič srečali. Diplomsko delo je predstavilo tudi trenutni odnos diaspore do Črne gore in Črne gore do diaspore, o katerem se v znanstvenih krogih skorajda ne govori.

3. // Crypto-Minding: postindustrijski podatkovni aktivizem : PostMobilnost; GO!2025 Evropska prestolnica kultureMarina Zafiris, Christopher Csikszentmihalyi, razstava Opis: // Stoletje obsedene industrializacije nam je širom zemeljske oble zapustilo obilico poceni energije, zemljišč in infrastrukture. Naraščajoči val »kripto-podjetnikov« spreminja odpisane industrijske prostore v objekte za »kripto rudarjenje«, neskončne algoritme poganjajo fosilna goriva in pri tem ustvarjajo vprašljivo vrednost. Razstava prikaže različne računalniške tehnike za sodelovanje in skrb v prizadeti skupnosti ter okolici elektrarne Greenidge Bitcoin Mining na jezeru Seneca v zvezni državi New York, ZDA. Predstavljene bodo umetniško-aktivistične intervencije v javno mnenje in taktike protinadzora, ter problematika toplotnega onesnaževanja voda. Gre za preizpraševanje proizvodnje javno dostopnega znanja in soustvarjanje računalniško podprtih orodjarn za radikalno družbeno organiziranje in politično komunikacijo. / Ob otvoritvi razstave postrežemo s pašteto soške postrvi spodnjega toka.

10. Aircraft vertical profiles during summertime regional and Saharan dust scenarios over the north-western Mediterranean basin: aerosol optical and physical propertiesJesús Yus-Díez, Marina Ealo, Marco Pandolfi, Noemi Perez, Gloria Titos, Griša Močnik, Xavier Querol, A. Alastuey, 2021, izvirni znanstveni članek Opis: Accurate measurements of the horizontal and vertical distribution of atmospheric aerosol particle optical properties are key for a better understanding of their impact on the climate. Here we present the results of a measurement campaign based on instrumented flights over north-eastern Spain. We measured vertical profiles of size-segregated atmospheric particulate matter (PM) mass concentrations and multi-wavelength scattering and absorption coefficients in the western Mediterranean basin (WMB). The campaign took place during typical summer conditions, characterized by the development of a vertical multi-layer structure, under both summer regional pollution episodes (REGs) and Saharan dust events (SDEs). REG patterns in the region form under high insolation and scarce precipitation in summer, favouring layering of highly aged fine-PM strata in the lower few kma.s.l.
The REG scenario prevailed during the entire measurement campaign. Additionally, African dust outbreaks and plumes from northern African wildfires influenced the study area. The vertical profiles of climate-relevant intensive optical parameters such as single-scattering albedo (SSA); the asymmetry parameter (g); scattering, absorption and SSA Ångström exponents (SAE, AAE and SSAAE); and PM mass scattering and absorption cross sections (MSC and MAC) were derived from the measurements. Moreover, we compared the aircraft measurements with those performed at two GAW–ACTRIS (Global Atmosphere Watch–Aerosol, Clouds and Trace Gases) surface measurement stations located in north-eastern Spain, namely Montseny (MSY; regional background) and Montsec d'Ares (MSA; remote site).
Airborne in situ measurements and ceilometer ground-based remote measurements identified aerosol air masses at altitudes up to more than 3.5 kma.s.l.
The vertical profiles of the optical properties markedly changed according to the prevailing atmospheric scenarios. During SDE the SAE was low along the profiles, reaching values < 1.0 in the dust layers. Correspondingly, SSAAE was negative, and AAE reached values up to 2.0–2.5, as a consequence of the UV absorption increased by the presence of the coarse dust particles. During REG, the SAE increased to > 2.0, and the asymmetry parameter g was rather low (0.5–0.6) due to the prevalence of fine PM, which was characterized by an AAE close to 1.0, suggesting a fossil fuel combustion origin. During REG, some of the layers featured larger AAE (> 1.5), relatively low SSA at 525 nm (< 0.85) and high MSC (> 9 m2 g−1) and were associated with the influence of PM from wildfires. Overall, the SSA and MSC near the ground ranged around 0.85 and 3 m2 g−1, respectively, and increased at higher altitudes, reaching values above 0.95 and up to 9 m2 g−1. The PM, MSC and MAC were on average larger during REG compared to SDE due to the larger scattering and absorption efficiency of fine PM compared with dust. The SSA and MSC had quite similar vertical profiles and often both increased with height indicating the progressive shift toward PM with a larger scattering efficiency with altitude.
This study contributes to our understanding of regional-aerosol vertical distribution and optical properties in the WMB, and the results will be useful for improving future climate projections and remote sensing or satellite retrieval algorithms.
