Phase transitions in a matrix model on a curved noncommutative space
Dragan Prekrat, Dragana Ranković, Neli Kristina Todorović-Vasović +2
In this contribution, we summarize our recent studies of the phase structure of the Grosse-Wulkenhaar model and its connection to renormalizability. Its action contains a special t…
Powerful Radio Sources in the Southern Sky. II. A SWIFT X-Ray Perspective
F. Massaro, S. V. White, A. Paggi +18
We recently constructed the G4Jy-3CRE, a catalog of extragalactic radio sources based on the GLEAM 4-Jy (G4Jy) sample, with the aim of increasing the number of powerful radio galax…
X-ray metal line emission from the hot circumgalactic medium: probing the effects of supermassive black hole feedback
Nhut Truong, Annalisa Pillepich, Dylan Nelson +15
We derive predictions from state-of-the-art cosmological galaxy simulations for the spatial distribution of the hot circumgalactic medium (CGM, ) through its…
Powerful Radio Sources in the Southern Sky. I. Optical Identifications
F. Massaro, S. V. White, A. Garcia-Perez +18
Since the early sixties, our view of radio galaxies and quasars has been drastically shaped by discoveries made thanks to observations of radio sources listed in the Third Cambridg…
Gaia21bty: An EXor lightcurve exhibiting an FUor spectrum
Michał Siwak, Lynne A. Hillenbrand, Ágnes Kóspál +16
Gaia21bty, a pre-main sequence star that previously had shown aperiodic dips in its light curve, underwent a considerable mag brightening that occurred over a few mo…
Want to Raise Cybersecurity Awareness? Start with Future IT Professionals
Lydia Kraus, Valdemar Švábenský, Martin Horák +3
As cyber threats endanger everyone, from regular users to computing professionals, spreading cybersecurity awareness becomes increasingly critical. Therefore, our university design…
