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.

BLAZAR ANTI-SEQUENCE OF SPECTRAL VARIABILITY FOR INDIVIDUAL TeV BLAZARS [PDF]
We compile from literature the broadband SEDs of twelve TeV blazars observed simultaneously or quasi-simultaneously with Fermi/LAT and other instruments. Two SEDs are available for each of the objects and the state is identified as a low or high state according to its flux density at GeV/TeV band.

General Physical Properties of Fermi Blazars
We study the general physical properties of Fermi blazars using the Fermi fourth source catalog data (4FGL-DR2). The quasi-simultaneous multiwavelength data of Fermi blazars are fitted by using the one-zone leptonic model to obtain some physical ...

Study on the Gamma-Ray Radiation Properties of High-Redshift Blazars at z > 2.5
The high-redshift blazars are important cosmological probes for exploring the early universe and unraveling the fundamental emission processes and the structure of the active galactic nuclei.

Using a wearable electrocardiogram (ECG) patch adapted for 7‐day monitoring in the horse
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]
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 ...

Extreme Jet Beaming Observed in Neutrino-associated Blazars
Bright 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 ...
