The phenomenon of ionic wind has been known about for centuries: by applying a voltage to a pair of electrodes, electrons are stripped off nearby air molecules, and the ionized air collides with neutral air molecules as it ...
(PhysOrg.com) -- On the nanoscale, things aren’t always what they seem. What first looked like a continuous plasma jet has turned out to be a train of tiny, high-velocity plasma bullets. Using a camera with an exposure ...
Researchers discovered only relatively recently that black hole jets emit X-rays, and how the jets accelerate particles to this high-energy state is still a mystery. Surprising new findings in Nature Astronomy appear to rule ...

Using NASA's Swift observatory and ESA's XMM-Newton satellite, Indian astronomers have inspected a prominent high synchrotron peaked blazar known as 1ES 1959+650. Results of the study, published May 5 on the arXiv pre-print ...
An international team of astronomers has conducted a long-term multiwavelength monitoring campaign of a nearby narrow-line Seyfert 1 galaxy known as SDSS J164100.10+345452.7. Results of the observations, published March 9 ...
Using the Very Large Telescope (VLT) of the European southern Observatory (ESO), an international team of astronomers has observed a tidal disruption event known as AT 2022cmc. Results of the observational campaign, presented ...
Earlier this year, astronomers were keeping tabs on data from the Zwicky Transient Facility, an all-sky survey based at the Palomar Observatory in California, when they detected an extraordinary flash in a part of the sky ...

An international team of astronomers reports the detection of highly collimated radio jets around a nearby radio galaxy known as NGC 2663. These jets, spanning a total of more than 1,150 light years, could help us improve ...
A Northwestern University-led team of astrophysicists has developed the first-ever full 3D simulation of an entire evolution of a jet formed by a collapsing star, or a "collapsar."
