Extreme Jet Beaming Observed in Neutrino-associated Blazars
The Astrophysical JournalBright blazars were found to be prominent neutrino sources, and a number of IceCube events were associated with them over recent years. A particularly strong observational connection is present between neutrinos and blazars with bright, Doppler-boosted ...

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.

Analyses of Social Issues and Public Policy, Volume 25, Issue 2, August 2025.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 ...

The RoboPol Program: Optical Polarimetric Monitoring of Blazars
Galaxies, 2019 After three years of polarimetric monitoring of blazars, the RoboPol project has uncovered several key characteristics of polarimetric rotations in the optical for these most variable sources.

Blazar Jets as Possible Sources of Ultra-High Energy Photons: A Short Review
Universe, 2022 In this paper, I present a qualitative discussion on the prospect of production of ultra-high photons in blazars. The sources are a subclass of active galactic nuclei which host supermassive black holes and fire relativistic jets into the intergalactic ...

Bayesian Approach to Find a Long-Term Trend in Erratic Polarization Variations Observed in Blazars [PDF]
, 2009 We developed a method to separate a long-term trend from observed temporal variations of polarization in blazars using a Bayesian approach. The temporal variation of the polarization vector is apparently erratic in most blazars, while several objects ...

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 ...

The VLBA-BU-BLAZAR Multi-Wavelength Monitoring Program
Galaxies, 2016 We describe a multiwavelength program of monitoring of a sample of bright γ-ray blazars, which the Boston University (BU) group has being carrying out since June 2007.

Gamma-Ray Cosmology and Tests of Fundamental Physics
Galaxies, 2022 The propagation of gamma-rays over cosmological distances is the subject of extensive theoretical and observational research at GeV and TeV energies. The mean free path of gamma-rays in the cosmic web is limited above 100 GeV due to the production of ...
