Journal of Policy Analysis and Management, Volume 45, Issue 2, Spring 2026.ABSTRACT Recruiting teachers via “grow‐your‐own” (GYO) programs is a popular, yet rarely evaluated, strategy for addressing local workforce shortages and ensuring that incoming teachers resemble, understand, and have strong connections to their communities.

Characterising the Long-Term Variability of Blazars in Leptonic Models
Galaxies, 2019 Most research on blazar variability focuses on individual flares to explain acceleration and radiation mechanisms and improve on current models. These short-time events (being minutes, hours, or days) might not be representative of the underlying ...

The Astrophysical Journal, 2023 Recent works have developed samples of blazars from among the Fermi Large Area Telescope unassociated sources via machine-learning comparisons with known blazar samples. Continued analysis of these new blazars tests the predictions of the blazar sequence

Journal of Engineering Education, Volume 115, Issue 1, January 2026.Abstract Background The ongoing underrepresentation of Latinx students, particularly girls, in engineering calls for new approaches to broaden participation. The present study aims to address this disparity by implementing a culturally responsive gamified engineering activity for migratory high school students, an often‐overlooked subset of Latinx ...

Leptohadronic Blazar Models Applied to the 2014–2015 Flare of TXS 0506+056 [PDF]
Astrophysical Journal, 2018 We investigate whether the emission of neutrinos observed in 2014–2015 from the direction of the blazar TXS 0506+056 can be accommodated with leptohadronic multiwavelength models of the source commonly adopted for the 2017 flare.

Cherenkov Telescope Array Observatory: Die Zukunft der Gammaastronomie
Physik in unserer Zeit, Volume 57, Issue 1, Page 10-18, January 2026.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.

Multi-wavelength Variability Signatures of Relativistic Shocks in Blazar Jets [PDF]
Astrophysical Journal, 2019 Mildly relativistic shocks that are embedded in colliding magnetohydrodynamic flows are prime sites for relativistic particle acceleration and the production of strongly variable, polarized multi-wavelength emission from relativistic jet sources such as ...

Astroparticle Physics, 1999 The kinetic energy of bulk relativistic plasma ejected from the central engine of blazars is converted into nonthermal particle energy in the comoving frame through a process of sweeping up material from the surrounding medium. The resulting deceleration of the bulk plasma introduces a number of effects which must be included in blazar modeling.
