Cherenkov Telescope Array Observatory: Die Zukunft der Gammaastronomie
Im Jahr 1989 hat das Wipple‐Observatorium die erste Quelle hochenergetischer Gammastrahlung entdeckt. 2002 waren dann sechs Quellen bekannt, 2024 schon mehr als 300. Und das ist immer noch lediglich die Spitze des Eisbergs in der jungen Geschichte der Gammaastronomie.

Theoretical Study of the Effects of Magnetic Field Geometry on the High-Energy Emission of Blazars
The knowledge of the structure of the magnetic field inside a blazar jet, as deduced from polarization observations at radio to optical wavelengths, is closely related to the formation and propagation of relativistic jets that result from accretion onto ...

Myeloid‐derived suppressor cells (MDSCs) are a heterogeneous population of immature myeloid cells that have been increasingly defined and characterized over the past two decades, known for their remarkable capacity to expand and exert immunosuppressive effects in various pathological contexts, such as malignancies, infections, and inflammatory diseases.

VLBI Observations of Nearby HBLs: Physical Implications
We review the jet kinematics of HBL blazars based on results of the MOJAVE survey, which obtained images of active galactic nuclei with the Very Long Baseline Array (VLBA) at 15 GHz, and the VLBA-BU-BLAZAR program as well as its successor BEAM-ME program,

The Long-Lasting Activity in the Flat Spectrum Radio Quasar (FSRQ) CTA 102
The flat spectrum radio quasar CTA 102 ( z = 1 . 032 ) went through a tremendous phase of variability. Since early 2016 the gamma-ray flux level has been significantly higher than in previous years. It was topped by a four month long giant outburst,

Progress in Multi-wavelength and Multi-Messenger Observations of Blazars and Theoretical Challenges
This review provides an overview of recent advances in multi-wavelength and multi-messenger observations of blazars, the current status of theoretical models for blazar emission, and prospects for future facilities.

Abstract Diversity education in the K‐12 years is a contentious issue in the contemporary US context. Given evidence that parental identity influences beliefs about and support for diversity education, we qualitatively explored cisgender‐heterosexual and LGBTQ+ parents’ (N = 609) beliefs about the appropriateness of inclusive educational policies in K ...

Error climate and alienation from teachers: A longitudinal analysis in primary school
Abstract Background Dealing with errors in the classroom is a crucial aspect of instructional quality and has multiple consequences for students' own dealing with errors, their learning and their achievement. The available literature on error climate indicates a paucity of research on the effects of perceived error climate on social aspects such as ...

Suborbital Fermi/LAT Analysis of the Brightest Gamma-Ray Flare of Blazar 3C 454.3
Recent detection of suborbital gamma-ray variability of Flat Spectrum Radio Quasar (FSRQ) 3C 279 by Fermi Large Area Telescope (LAT) is in severe conflict with established models of blazar emission.
