We outline a simple procedure designed for \emph{automatically} finding sets of multiple images in strong lensing (SL) clusters. We show that by combining (a) an arc-finding (or so…

Detecting strongly lensed supernovae at z ~ 5-7 with LSST
Claes-Erik Rydberg, Daniel J. Whalen, Matteo Maturi +4
Supernovae (SNe) could be powerful probes of the properties of stars and galaxies at high redshifts in future surveys. Wide fields and longer exposure times are required to offset…

[abridged] Characterizing the number counts of faint, dusty star-forming galaxies is currently a challenge even for deep, high-resolution observations in the FIR-to-mm regime. They…
EasyCritics I: Efficient detection of strongly-lensing galaxy groups and clusters in wide-field surveys
Sebastian Stapelberg, Mauricio Carrasco, Matteo Maturi
We present EasyCritics, an algorithm to detect strongly-lensing groups and clusters in wide-field surveys without relying on a direct recognition of arcs. EasyCritics assumes that…

J. González-López, F. E. Bauer, M. Aravena +12
Most sub-mm emission line studies of galaxies to date have targeted sources with known redshifts where the frequencies of the lines are well constrained. Recent blind line scans ci…

J. González-López, F. E. Bauer, C. Romero-Cañizales +21
Dusty star-forming galaxies are among the most prodigious systems at high redshift (z>1), characterized by high star formation rates and huge dust reservoirs. The bright end of thi…
