Researchers at the Indian Institute of Astrophysics found evidence of a radio jet interacting with interstellar gas in a dwarf galaxy (NGC 4395).
This is the first time such an interaction has been detected in a dwarf galaxy, challenging previous beliefs that only large galaxies with massive black holes produce these jets.
This finding could change our understanding of how active galactic nuclei (AGN) work and their role in star formation.
Radio Jet
A stream of material emitted from the center of some galaxies, traveling nearly at the speed of light.
Produces strong radio waves, which can be detected by radio telescopes.
Interstellar Gas
The gas found in the space between stars within a galaxy.
It plays a crucial role in star formation and can interact with jets from black holes, affecting the galaxy's dynamics.
Interstellar gas consists mostly of hydrogen in its neutral form.
Radio telescopes can detect neutral hydrogen because it emits radiation at a wavelength of 21 cm.
