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 […]

International Women’s Day

March 9, 2023

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. […]

New pulsars in old data – by Sengar et al.

March 7, 2023

The Parkes Multi-beam Pulsar Survey (PMPS) was a large survey undertaken between 1997 and 2002 with the Parkes 64m radio-telescope, Murriyang. The original processing of the data discovered over 600 […]

New pulsars in old data – by Sengar et al.

March 6, 2023

The Parkes Multi-beam Pulsar Survey (PMPS) was a large survey undertaken between 1997 and 2002 with the Parkes 64m radio-telescope, Murriyang, using the then-new 13-beam 20cm multi-beam receiver , with […]

Early days at Narrabri

This image from 1963, showing the construction of the Culgoora Radioheliograph near Narrabri was featured on the CSIRO_ATNF twitter account recently. A circular array of 96 antennas, the Radioheliograph could […]

New pulsars in old data – by Sengar et al.

March 2, 2023

The Parkes Multi-beam Pulsar Survey (PMPS) was a large survey undertaken between 1997 and 2002 with the Parkes 64m radio-telescope, Murriyang. The PMPS covered a 10 degree strip centred on […]

ATNF Colloquium – Scintillation Arcs: Scattering Screens and Surprises

March 1, 2023

Robert Main (MPIfR) Abstract: Radio emission from pulsars scintillates in time and frequency – an interference pattern arising from small-scale inhomogeneities in electron density in the interstellar medium. The discovery […]
