HI absorption associated with Norma’s brightest cluster galaxy – by Saraf et al.

March 14, 2023

ESO 137-G006 is the brightest cluster galaxy (BCG) of the cool-core and dynamically young Norma cluster. Saraf et al. report the discovery of an atomic hydrogen (HI) absorption line associated […]

A multi-wavelength view of the galaxy cluster SPT-CL J0607-4448 – by Masterson et al.

March 13, 2023

A galaxy cluster contains tens to hundreds of member galaxies surrounded by hot, ionized plasma called the intracluster medium (ICM). The ICM is the dominant baryonic component of clusters, and […]

Spiral arms around a high mass proto-star – by Burns et al.

March 10, 2023

High-mass protostars (with masses greater than 8 solar masses) are thought to gain the majority of their mass via short, intense bursts of growth. This episodic accretion is thought to […]

March 8th is celebrated as International Women’s Day. The United Nations first recognised International Women’s Day in 1975. Since then it has been commemorated annually by the UN and much […]

ATNF Colloquium – Galactic HII regions, diffuse ionised gas, and structure in the Milky Way

March 8, 2023

Trey Wenger (U. of Wisconsin-Madison) Abstract: Radio recombination lines (RRLs) are an unobscured tracer of ionized gas in both the diffuse interstellar medium (ISM) as well as high-mass star-forming regions. […]
