The Impact of Plasma Instabilities on the Spectra of TeV Blazars [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Relativistic jets from blazars are known to be sources of very-high-energy gamma rays (VHEGRs). During their propagation in the intergalactic space, VHEGRs interact with pervasive cosmological photon fields such as the extragalactic background light ...

Error climate and alienation from teachers: A longitudinal analysis in primary school
British Journal of Educational Psychology, Volume 95, Issue 1, Page 41-54, March 2025.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 ...

Can teaching be taught? Improving teachers' pedagogical skills at scale in rural Peru
Quantitative Economics, Volume 16, Issue 1, Page 185-233, January 2025.We evaluate the impact of a large‐scale teacher coaching program in Peru, a context with high teacher turnover, on teachers' pedagogical skills and student learning. Previous studies find that small‐scale coaching programs can improve teaching of reading and science in developing countries.

TeV blazars and their distance [PDF]
Proceedings of Cosmic Radiation Fields: Sources in the early Universe — PoS(CRF 2010), 2011 Recently, a new method to constrain the distance of blazars with unknown redshift using combined observations in the GeV and TeV regimes has been developed, with the underlying assumption that the Very High Energy (VHE) spectrum corrected for the absorption of TeV photons by the Extragalactic Background Light (EBL) via photon-photon interaction should ...

Review of Education, Volume 12, Issue 3, December 2024.Abstract The world map is changing due to waves of immigration, population and demographic changes in mainland Europe and North America. There is a growing need for a more diverse teacher workforce to close the racial and ethnic gap between students and teachers in populations with high diversity.

The Extremes in Intra-Night Blazar Variability: The S4 0954+65 Case
Galaxies, 2016 We present results of optical observations of the extremely violently variable blazar S4 0954+65 on intra-night time scales. The object showed flux changes of up to 100% within a few hours.

Herschel-ATLAS: Blazars in the science demonstration phase field [PDF]
, 2010 To investigate the poorly constrained sub-mm counts and spectral properties of blazars we searched for these in the Herschel-ATLAS (H-ATLAS) science demonstration phase (SDP) survey catalog.
