Haojing Yan et al 2023 ApJL 942 L8

Several candidate high-redshift galaxies in JWST data are unknown in nature, as they cannot be explained by usual contaminants but are more numerous and more luminous than our theories would suggest.

Researchers suggest that the X-ray emission from the radio lobes of Pictor A is due to synchrotron radiation from high-energy (10–100 tera-electronvolts) electrons spiraling around magnetic field lines.

The full data release of a survey of the inner galactic plane will be useful for astronomers studying the properties of individual molecular clouds as well as structures within the Milky Way’s spiral arms.

Yunjing Wu et al 2023 ApJL 942 L1

Using JWST observations, researchers have identified the most distant galaxy showing distinct spiral structure ever, at a time when the universe was only about 2 billion years old.

Alex Griffiths et al 2022 ApJ 941 181

Hubble observations suggest that low-mass, line-emitting galaxies might not be a main source of photons during the epoch of reionization, during which the abundant neutral hydrogen gas in the universe was ionized.

Observations with the Very Large Telescope reveal the plasma within a planetary nebula to be complex, containing two components with different temperatures, densities, and chemical compositions.
