Effect of Background Magnetic Field on Ion Weibel Instability With High‐Intensity Short‐Pulse Lasers

Contributions to Plasma Physics, EarlyView.
ABSTRACT The effect of finite background magnetic field on magnetic field amplification by Weibel instability using high‐intensity short‐pulse lasers is investigated. We consider Weibel instability for counter‐streaming sub‐relativistic plasma flows generated by shooting pure carbon targets with short‐pulse lasers.

RESOLVING THE ACTIVE GALACTIC NUCLEUS AND HOST EMISSION IN THE MID-INFRARED USING A MODEL-INDEPENDENT SPECTRAL DECOMPOSITION [PDF]

, 2015
We present results on the spectral decomposition of 118 Spitzer Infrared Spectrograph (IRS) spectra from local active galactic nuclei (AGNs) using a large set of Spitzer/IRS spectra as templates.

The Fermi Bubbles. I. Possible Evidence for Recent AGN Jet Activity in the Galaxy

, 2012
The Fermi Gamma-ray Space Telescope reveals two large gamma-ray bubbles in the Galaxy, which extend about 50 degrees (~ 10 kpc) above and below the Galactic center (GC) and are symmetric about the Galactic plane.

Adverse Outcome Pathways Applied to Space Radiation Research

Environmental and Molecular Mutagenesis, EarlyView.
ABSTRACT Long‐duration spaceflight exposes astronauts to various stressors that can alter human physiology, potentially causing immediate and long‐term health effects. These stressors can damage biomolecules, cells, tissues, and organs, leading to adverse outcomes.

AGN/Starburst Connection

Acta Polytechnica CTU Proceedings, 2014
Two main physical processes characterize the activity in the nuclear region of active galaxies: an intense star formation (starburst, SB) and an Active Galactic Nucleus (AGN).

Star formation history in barred spiral galaxies – active galactic nucleus feedback [PDF]

, 2017
We present a numerical study of the impact of AGN accretion and feedback on the star formation history of barred disc galaxies. Our goal is to determine whether the effect of feedback is positive (enhanced star formation) or negative (quenched star ...

Illuminating Satellite Cells: Light Sheet Fluorescence Microscopy for 3D Imaging of Murine Skeletal Muscles Damaged by Ex Vivo Forced Eccentric Contraction

Microscopy Research and Technique, EarlyView.
This study presents the light sheet fluorescence microscopy (LSFM) as a tool for 3D‐imaging of whole skeletal muscle to reveal satellite cells (SCs), the muscle stem cells that activate following damage to repair injured tissue. After tissue clearing and whole‐mount staining process aimed to enable optical access and specific cell labeling (1), murine ...

Factors Determining Variability Time in Active Galactic Nucleus Jets [PDF]

Publications of the Astronomical Society of Australia, 2002
AbstractThe relationship between observed variability time and emission region geometry is explored for the case of emission by relativistic jets.The approximate formula for the jet-frame size of the emission region, R′ = DcΔtobs, is shown to lead to large systematic errors when used together with observed luminosity and assumed or estimated Doppler ...
