Lensed stars in galaxy-galaxy strong lensing -- a JWST prediction for the Cosmic Horseshoe
Sung Kei Li, Luke Weisenbach, Thomas E. Collett +10
We explore for the first time the possibility of detecting lensed star transients in galaxy-galaxy strong lensing systems upon repeated, deep imaging using the {\it James-Webb Spac…
Multi-band Reconstruction of Sixteen Gravitational Lens Systems using PISCO data
Huimin Qu, Daniel J. Ballard, Geraint F. Lewis +12
Next-generation surveys such as the Euclid survey, the Legacy Survey of Space and Time (LSST), and the China Space Station Telescope (CSST) survey are expected to discover ~10^5 ga…
Constraining Cosmology with Double-source-plane Strong Gravitational Lenses from the AGEL Survey
Duncan J. Bowden, Nandini Sahu, Anowar J. Shajib +17
Double-source-plane strong gravitational lenses (DSPLs), with two sources at different redshifts, are independent cosmological probes of the dark energy equation of state parameter…
Unveiling a 36 Billion Solar Mass Black Hole at the Centre of the Cosmic Horseshoe Gravitational Lens
Carlos R. Melo-Carneiro, Thomas E. Collett, Lindsay J. Oldham +4
Supermassive black holes (SMBHs) are found at the centre of every massive galaxy, with their masses tightly connected to their host galaxies through a co-evolution over cosmic time…
Cosmography with the Double Source Plane Strong Gravitational Lens AGEL150745+052256
Nandini Sahu, Anowar J. Shajib, Kim-Vy Tran +14
Strong gravitational lenses with two background sources at widely separated redshifts are a powerful and independent probe of cosmological parameters. We can use these systems, kno…
The La Silla Schmidt Southern Survey
Adam A. Miller, Natasha S. Abrams, Greg Aldering +75
We present the La Silla Schmidt Southern Survey (LS4), a new wide-field, time-domain survey to be conducted with the 1 m ESO Schmidt telescope. The 268 megapixel LS4 camera mosaics…
