VSOP observation of the quasar PKS 2215+020: a new laboratory for core-jet physics at z=3.572 [PDF]

, 2000
We report results of a VSOP (VLBI Space Observatory Programme) observation of a high redshift quasar PKS 2215+020 (z=3.572). The ~1 milliarcsecond resolution image of the quasar reveals a prominent `core-jet' structure on linear scales from 5/h to 300/h ...

Earth's Energy Imbalance More Than Doubled in Recent Decades

AGU Advances, Volume 6, Issue 3, June 2025.
Abstract Global warming results from anthropogenic greenhouse gas emissions which upset the delicate balance between the incoming sunlight, and the reflected and emitted radiation from Earth. The imbalance leads to energy accumulation in the atmosphere, oceans and land, and melting of the cryosphere, resulting in increasing temperatures, rising sea ...

Boosted dark matter from Centaurus A and its detection

Journal of High Energy Physics
Dark matter can be boosted by high energy particles in astrophysical environments through elastic scattering. We study the production of boosted dark matter via scattering with electrons in the relativistic jet of the closest active galactic nucleus ...

High-energy Neutrino Emission Associated with GWs from Binary Black Hole Mergers in AGN Accretion Disks

The Astrophysical Journal Letters, 2023
The search for multimessenger signals of binary black hole (BBH) mergers is crucial to understanding the merger process of BBH and the relative astrophysical environment.

Impact of Teachers With Research Experiences: Student Gains in STEM Career Awareness, Perception of Value of STEM Learning, and Persistence in STEM Course Tasks

Science Education, Volume 109, Issue 3, Page 769-795, May 2025.
ABSTRACT Research Experiences for Teachers (RET) programs are a burgeoning approach to engage teachers in STEM (science, technology, engineering, mathematics) research that they can translate into their K‐12 classrooms. Despite an increase in studies of RETs, there is a need for comparison of RET and non‐RET teachers' student outcomes.

Microphysical Plasma Relations from Special-relativistic Turbulence

The Astrophysical Journal, 2023
The microphysical, kinetic properties of astrophysical plasmas near accreting compact objects are still poorly understood. For instance, in modern general-relativistic magnetohydrodynamic simulations, the relation between the temperature of electrons T ...

Investigation of Gas‐Surface Interactions and Neutral Atmospheric Properties and Their Impact on Satellite Drag Coefficients

Earth and Space Science, Volume 12, Issue 5, May 2025.
Abstract Changes in the thermospheric composition and temperature influence satellite drag coefficients through functional dependencies in the closed‐form solutions, and gas‐surface interactions via accommodation coefficients. This study investigates drag coefficient variations for the Gravity Recovery And Climate Experiment (GRACE) and Communications ...

3D NUMERICAL HYDRODYNAMICAL MODELS OF THE PRECESSING THICK ACCRETION DISK AND ON- AND OFF-STATE GENERATIONS IN MICROQUASARS

Odessa Astronomical Publications, 2017
The thick accretion disk and donor’s wind on the example of CYG X-1 are computed. The main aim of the present simulations is to calculate the precessing thick accretion disk and ON- and OFF-state generation by the methods of 3D numerical hydrodynamics ...
