The Prime Extragalactic Areas for Reionization and Lensing Science (PEARLS), a JWST GTO program, obtained a set of unique NIRCam observations that have enabled us to significantly…
ProPane: Image Warping with Fire
A. S. G. Robotham, R. Tobar, S. Bellstedt +7
In this paper we introduce the software package ProPane, written for the R data analysis language. ProPane combines the full range of wcslib projections with the C++ image manipula…
Dynamic Wisp Removal in JWST NIRCam Images
A. S. G. Robotham, J. C. J. D'Silva, R. A. Windhorst +5
The James Webb Space Telescope (JWST) near-infrared camera (NIRCam) has been found to exhibit serious wisp-like structures in four of its eight short-wavelength detectors. The exac…
Hydra II: Characterisation of Aegean, Caesar, ProFound, PyBDSF, and Selavy source finders
M. M. Boyce, A. M. Hopkins, S. Riggi +24
We present a comparison between the performance of a selection of source finders using a new software tool called Hydra. The companion paper, Paper~I, introduced the Hydra tool and…
Hydra I: An extensible multi-source-finder comparison and cataloguing tool
M. M. Boyce, A. M. Hopkins, S. Riggi +24
The latest generation of radio surveys are now producing sky survey images containing many millions of radio sources. In this context it is highly desirable to understand the perfo…
SKYSURF-4: Panchromatic HST All-Sky Surface-Brightness Measurement Methods and Results
Rosalia O'Brien, Timothy Carleton, Rogier A. Windhorst +22
The diffuse, unresolved sky provides most of the photons that the Hubble Space Telescope (HST) receives, yet remains poorly understood. HST Archival Legacy program SKYSURF aims to…
Current and Next Generation Survey Filter Conversions with ProSpect
Aaron S. G. Robotham
In this work we compute a reasonably comprehensive set of tables for current and next generation survey facility filter conversions. Almost all useful transforms are included with…
The Detailed Science Case for the Maunakea Spectroscopic Explorer, 2019 edition
The MSE Science Team, Carine Babusiaux, Maria Bergemann +258
(Abridged) The Maunakea Spectroscopic Explorer (MSE) is an end-to-end science platform for the design, execution and scientific exploitation of spectroscopic surveys. It will unvei…
4MOST Survey Strategy Plan
G. Guiglion, C. Battistini, C. P. M. Bell +30
The current status of and motivation for the 4MOST Survey Strategy, as developed by the Consortium science team, are presented here. Key elements of the strategy are described, suc…
4MOST Scientific Operations
C. J. Walcher, M. Banerji, C. Battistini +65
The 4MOST instrument is a multi-object spectrograph that will address Galactic and extragalactic science cases simultaneously by observing targets from a large number of different…
4MOST: Project overview and information for the First Call for Proposals
R. S. de Jong, O. Agertz, A. Agudo Berbel +335
We introduce the 4-metre Multi-Object Spectroscopic Telescope (4MOST), a new high-multiplex, wide-field spectroscopic survey facility under development for the four-metre-class Vis…
Climbing Halo Merger Trees with TreeFrog
Pascal J. Elahi, Rhys J. J. Poulton, Rodrigo J. Tobar +4
We present TreeFrog, a massively parallel halo merger tree builder that is capable comparing different halo catalogues and producing halo merger trees. The code is written in c++11…
ProFound: Source Extraction and Application to Modern Survey Data
A. S. G. Robotham, L. J. M. Davies, S. P. Driver +4
