Problems with fixpoints of polynomials of polynomials

Cécilia Pradic, Ian Price

Motivated by applications in computable analysis, we study fixpoints of certain endofunctors over categories of containers. More specifically, we focus on fibred endofunctors over…

The 2dF Galaxy Redshift Survey: The Number and Luminosity Density of Galaxies

Nicholas Cross, Simon P. Driver, Warrick Couch +29

We present the bivariate brightness distribution (BBD) for the 2dF Galaxy Redshift Survey (2dFGRS) based on a preliminary subsample of 45,000 galaxies. The BBD is an extension of t…

Emu: A Case Study for TDI-like Imaging for Infrared Observation from Space

Joice Mathew, James Gilbert, Robert Sharp +14

A wide-field zenith-looking telescope operating in a mode similar to Time-Delay-Integration (TDI) or drift scan imaging can perform an infrared sky survey without active pointing c…

Converting the ANU 2.3 telescope to fully automated operation

Ian Price, Jon Nielsen, Chris Lidman +3

The operation of the ANU 2.3m telescope transitioned from classically scheduled remote observing to fully autonomous queue scheduled observing in March 2023. The instrument current…
