ASKAP HI imaging of the galaxy group IC 1459
P. Serra, B. Koribalski, V. Kilborn +76
We present HI imaging of the galaxy group IC 1459 carried out with six antennas of the Australian SKA Pathfinder equipped with phased-array feeds. We detect and resolve HI in eleve…
Bandpass calibration of a wideband spectrometer using coherent pulse injection
Nipanjana Patra, Justin D. Bray, Paul Roberts +1
We present a relatively simple time domain method for determining the bandpass response of a system by injecting a nanosecond pulse and capturing the system voltage output. A pulse…
BIGHORNS - Broadband Instrument for Global HydrOgen ReioNisation Signal
M. Sokolowski, S. E. Tremblay, R. B. Wayth +12
The redshifted 21cm line of neutral hydrogen (HI), potentially observable at low radio frequencies (~50-200 MHz), should be a powerful probe of the physical conditions of the inter…
