ATNF Colloquium – Some FRB physics and an explanation of their Galactic latitude dependence

March 25, 2015

by J-P Macquart (Curtin University) Abstract. The detection of millisecond-duration Fast Radio Bursts (FRBs) at apparently cosmological distances has opened up new possibilities of probing the Intergalactic Medium. The dispersion […]

ATNF summer students visiting the ATCA

by Bärbel Koribalski (CASS) Five antennas of CSIRO’s Australia Telescope Compact Array (ATCA) can be moved to different stations along the east-west track (seen in this picture) and, occasionally, the […]

Two Radio Emission Mechanisms in PSR J0901-4624

March 21, 2015

by Simon Johnston (CASS) Raithel, Shannon, Johnston & Kerr (2015) detected sporadic, bright, short-duration radio pulses from PSR J0901-4624. These pulses are emitted simultaneously with persistent, periodic emission that dominates […]

Another shock for the Bullet cluster

March 20, 2015

by Tim Shimwell (Leiden University, The Netherlands) With Australia Telescope Compact Array (ATCA) observations we ( Shimwell et al. 2015 ) detect a highly elongated Mpc-scale diffuse radio source on […]

Measuring Galaxy Structure from WALLABY Gas Kinematics

March 19, 2015

by Kristine Spekkens (RMC, Canada) WALLABY , the top-ranked spectral line survey that will be carried out with the Australian SKA Pathfinder (ASKAP), will revolutionize our understanding of local galaxy […]

ATNF Colloquium – Witnessing the Formation of Massive, Distant Galaxies in the (Sub)Millimeter Regime

March 18, 2015

by Helmut Dannerbauer (University of Vienna, Austria) Abstract. In order to understand galaxy formation it is crucial to obtain sensitive observations of the emission of dust and molecular gas both […]

The ASKAP HI All Sky Survey

March 17, 2015

by Bärbel Koribalski (CASS) WALLABY is the “ASKAP HI All-Sky Survey” , a precursor for future, much deeper SKA Phase 1 & Phase 2 neutral hydrogen (HI) surveys. With an […]

The “tail” of ESO 324-G024

March 16, 2015

by Megan Johnson (CASS) ESO 324-G024 is a dwarf irregular galaxy in the Centaurus A galaxy group and lies only ~104 kpc from the center of NGC 5128, which is […]

A dwarf galaxy with a giant hydrogen disk

March 15, 2015

by Bärbel Koribalski (CASS) ESO 215-G?009 is a rather isolated, nearby dwarf irregular galaxy, somewhat obscured by Milky Way stars and dust. Its neutral hydrogen (HI) disk, as measured with […]
