, 2020 International audienceThe uncharted territory of the high-redshift (z ≳ 3) universe holds the key to understanding the evolution of quasars. In an attempt to identify the most extreme members of the quasar population, that is, blazars, we have carried ...

The Central Engines of Fermi Blazars
, 2021 We present a catalog of central engine properties, i.e., black hole mass ($M_{BH}$) and accretion luminosity ($L_{disk}$), for a sample of 1077 blazars detected with the Fermi Large Area Telescope.

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.

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.

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.

Exploring γ-Ray Flares from High-Redshift Blazar B3 1343+451 at GeV Energies
UniverseWe study the temporal and spectral variability properties of the high-redshift blazar B3 1343+451 utilizing Fermi-LAT data from 2008 to 2022 in the energy range of 0.1–300 GeV.

Variability of Blazars and Blazar Models over 38 Years [PDF]
Galaxies, 2016 Since 1978, when BL Lac objects and violently variable quasars were married to become “blazars”, physical interpretations of the phenomenon have evolved. Remarkably, though, the general picture of relativistic jets beaming their radiation in our direction, proposed that year by Blandford and Rees, remains intact.

Lessons from the apparent peculiar nature of the star TYC 6544‐3483‐1
Astronomische Nachrichten, Volume 345, Issue 4, May 2024.Abstract We report a radio and optical study of the star TYC 6544‐3483‐1 originally selected as a follow‐up target in the course of our efforts to cross‐identify Galactic high‐energy sources. The star by itself finally turned out to be a very ordinary main‐sequence star despite the initial expectations that apparently pointed to the contrary.
