J1721+8842: The first Einstein zig-zag lens
F. Dux, M. Millon, C. Lemon +16
We report the discovery of the first example of an Einstein zig-zag lens, an extremely rare lensing configuration. In this system, J1721+8842, six images of the same background qua…
lightcurver: A Python Pipeline for Precise Photometry of Multiple-Epoch Wide-Field Images
Frédéric Dux
lightcurver is a photometric pipeline for time series astronomical imaging data, designed for the semi-automatic extraction of precise light curves from small, blended targets. Suc…
TDCOSMO. XVI. Measurement of the Hubble Constant from the Lensed Quasar WGD20384008
Kenneth C. Wong, Frédéric Dux, Anowar J. Shajib +17
Time-delay cosmography is a powerful technique to constrain cosmological parameters, particularly the Hubble constant (). The TDCOSMO collaboration is performing an ongoing…
The DELVE Quadruple Quasar Search I. A Lensed Low Luminosity AGN
Paul L. Schechter, Dominique Sluse, Erik A. Zaborowski +25
A quadruply lensed source, J125856.3-031944, has been discovered using the DELVE survey and WISE W1 - W2 colors. Followup direct imaging carried out with the Magellan Baade 6.5 m t…
Image deconvolution and PSF reconstruction with STARRED: a wavelet-based two-channel method optimized for light-curve extraction
Martin Millon, Kevin Michalewicz, Frédéric Dux +2
We present STARRED, a Point Spread Function (PSF) reconstruction, two-channel deconvolution, and light curve extraction method designed for high-precision photometric measurements…
