Long-Term Optical Monitoring of Blazars
Galaxies, 2019 Systematic monitoring of specific targets in the optical regime was historically applied on a very narrow sample of known variable stars. The discovery of blazars in the 20th century brought to the foreground the need for new global sky surveys, covering

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.

Source Count Distribution of Fermi LAT Gamma-Ray Blazars Using Novel Nonparametric Methods
UniverseWe utilized a sample from the Fermi-LAT 14-year Source Catalog by adjusting the flux detection threshold, enabling us to derive the intrinsic source count distribution dN/dF25 of extragalactic blazars using nonparametric, unbinned methods developed by ...

Polarization Vector Rotations: Real, Spurious, Hidden and Imaginary
Galaxies, 2016 Large and variable polarization is an inherent property of a majority of blazars. Systematic rotations of the polarization vector have been claimed for several blazars. In some cases, however, the reality of these rotations may be questionable.

Astroparticle Physics, 1999 TeV emission can be a common characteristic of low power blazars. This is in line with the sequence of blazars relating the observed bolometric luminosity with their overall spectral energy distribution. Detecting new TeV blazars, possibly at different redshifts, is important for studying the particle acceleration process operating in the jet, and it ...

Radiation processes in blazars [PDF]
AIP Conference Proceedings, 1997 We present an overview of the current theoretical models attempting to describe the structure and radiative processes operating in blazars and discuss the observational constraints that these models must confront.

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.
