The XMM Cluster Survey: new evidence for the 3.5 keV feature in clusters is inconsistent with a dark matter origin
S. Bhargava, P. A. Giles, A. K. Romer +14
There have been several reports of a detection of an unexplained excess of X-ray emission at 3.5 keV in astrophysical systems. One interpretation of this excess is the dec…
An optimised tiling pattern for multi-object spectroscopic surveys: application to the 4MOST survey
E. Tempel, T. Tuvikene, M. M. Muru +22
Large multi-object spectroscopic surveys require automated algorithms to optimise their observing strategy. One of the most ambitious upcoming spectroscopic surveys is the 4MOST su…
OzDES multi-object fibre spectroscopy for the Dark Energy Survey: Results and second data release
C. Lidman, B. E. Tucker, T. M. Davis +101
We present a description of the Australian Dark Energy Survey (OzDES) and summarise the results from its six years of operations. Using the 2dF fibre positioner and AAOmega spectro…
The Host Galaxies of Rapidly Evolving Transients in the Dark Energy Survey
P. Wiseman, M. Pursiainen, M. Childress +72
Rapidly evolving transients (RETs), also termed fast blue optical transients (FBOTs), are a distinct class of astrophysical event. They are characterised by lightcurves that declin…
Observing the earliest moments of supernovae using strong gravitational lenses
Max Foxley-Marrable, Thomas E. Collett, Chris Frohmaier +4
We determine the viability of exploiting lensing time delays to observe strongly gravitationally lensed supernovae (gLSNe) from first light. Assuming a plausible discovery strategy…
Probabilistic fibre-to-target assignment algorithm for multi-object spectroscopic surveys
E. Tempel, P. Norberg, T. Tuvikene +22
Context. Several new multi-object spectrographs are currently planned or under construction that are capable of observing thousands of Galactic and extragalactic objects simultaneo…
