Searches for IceCube neutrinos from blazar flares using correlations with gamma-ray lightcurves [PDF]
EPJ Web of Conferences, 2019 Blazars have long been considered as accelerator candidates for cosmic rays. In such a scenario, hadronic interactions in the jet would produce neutrinos and gamma rays.

Probing Neutrino Production in Blazars by Millimeter VLBI
Galaxies, 2023 The advancement of neutrino observatories has sparked a surge in multi-messenger astronomy. Multiple neutrino associations among blazars are reported while neutrino production sites are located within their central (sub)parsecs.

A tool to understand emission mechanisms of blazars through their high‐energy gamma‐ray emission
Astronomische Nachrichten, Volume 344, Issue 6, August 2023., 2023 The blazar SED is characterized by two energy components. Evidence suggests that the low‐energy component is generated by the synchrotron mechanism, but for the high‐energy component, the mechanism is still uncertain. Two main models have been proposed to explain this emission. According to the leptonic model, a correlation between the emission of both

The impact of guardian's usage of the Internet on children's cognitive skills
International Studies of Economics, Volume 18, Issue 2, Page 193-210, June 2023., 2023 Abstract In the digital age, the internet has become an essential source of information gathering and maintains a network of social contact. In this paper, we use microdata from the China Family Panel Studies to examine the effects of guardian's internet use on teenager's cognitive skills.

Multiwavelength astrophysics of the blazar OJ 287 and the project MOMO
Astronomische Nachrichten, Volume 344, Issue 4, May 2023., 2023 Abstract We are carrying out the densest and longest multiyear, multiwavelength monitoring project of OJ 287 ever done. The project MOMO (Multiwavelength Observations and Modeling of OJ 287) covers wavelengths from the radio to the high‐energy regime. A few selected observations are simultaneous with those of the Event Horizon Telescope (EHT).

To what extent a modern teaching style benefits students? Why do teachers act the way they do?
Journal of Computer Assisted Learning, Volume 39, Issue 2, Page 578-590, April 2023., 2023 Abstract Background The growth of teaching practices conducted to promote cognitive activation and active participation in the classroom in recent years has become the epicentre of an active debate regarding their effectiveness. Objectives This study is aimed to shed some light on this topic by empirically analysing the causes and consequences of more ...

Kinematics of Parsec-scale Jets of Gamma-Ray Blazars at 43 GHz within the VLBA-BU-BLAZAR Program [PDF]
, 2017 We analyze the parsec-scale jet kinematics from 2007 June to 2013 January of a sample of γ-ray bright blazars monitored roughly monthly with the Very Long Baseline Array at 43 GHz.

Journal of Computer Assisted Learning, Volume 39, Issue 1, Page 269-285, February 2023., 2023 Abstract Background Globally, digital skills are a crucial aspect of education that schools should develop systematically. Research on digital skills tends to be measured using self‐reports, performance tests or interventions. There is less knowledge about student and teacher uptake of technology in school, making it important to investigate the actual
