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 ...

Using a wearable electrocardiogram (ECG) patch adapted for 7‐day monitoring in the horse
Equine Veterinary Journal, EarlyView.Abstract Background Arrhythmias can cause poor performance and sudden death in horses. Long‐term (>24 h) electrocardiogram (ECG) monitoring has been used to identify arrhythmias in humans and is superior to short‐term monitoring for transient arrhythmia detection. Televet is the current equine gold‐standard ECG device. The Cardea SOLO™ (CS) is a single‐

Physics from Time Variability of the VHE Blazar PKS 2155-304 [PDF]
, 2010 Blazars are the principal extragalactic sources of very high energy gamma-ray emission in the Universe. These objects constitute a sub-class of Active Galactic Nuclei whose emission is dominated by Doppler boosted non-thermal radiation from plasma ...

Galaxies, 2016 This paper discusses the spectral energy distribution (SED) of all blazars with redshift detected by the Fermi satellite and listed in the 3LAC catalog. The so called “blazar sequence” from the phenomenological point of view will be updated, with no theory or modelling. It will be shown that: (i) pure data show that jet and accretion power are related;

Medical and Veterinary Entomology, Volume 40, Issue 3, Page 478-488, September 2026.Mortality for diatomaceous earth was observed as early as 2 h after exposure with 50% and 90% mortality at 3.5 and 4.6 h (LT50 and LT90, respectively) for Musca domestica. The LT50 and LT90 increased when the size of the fly species increased (M. domestica to Cochliomyia macellaria to Sarcophaga bullata) and increased for all three from 50 to 70 ...

Probes of the Inner Jets of Blazars [PDF]
, 1996 I review models for the 'inner jet" in blazars, the section that connects the central engine with the radio jet. I discuss how the structure and physics of the inner jet can he explored using millimeter-wave VLBI as well as multiwaveband observations of ...

Annalen der Physik, Volume 538, Issue 6, June 2026.This study examines slowly rotating traversable wormholes supported by string fluids whose properties change with radius. The matter smoothly shifts from a de Sitter‐like core to a string‐dominated exterior, producing a regular, horizon‐free spacetime.

The Extremes in Intra-Night Blazar Variability: The S4 0954+65 Case
Galaxies, 2016 We present results of optical observations of the extremely violently variable blazar S4 0954+65 on intra-night time scales. The object showed flux changes of up to 100% within a few hours.

Classification of blazars based on data-driven approaches
Astronomy & AstrophysicsContext. Active galactic nuclei (AGNs), including blazars, exhibit distinctive variability in their optical light curves, making them ideal for classification studies. This work uses data from the latest GAIA and Pan-STARRS data releases to analyze these

Galaxies, 2016 Since the mid-1980s, the shock-in-jet model has been the preferred paradigm to explain radio-band flaring in blazar jets. We describe our radiative transfer model incorporating relativistically-propagating shocks, and illustrate how the 4.8, 8, and 14.5 ...
