An archival search for gamma-ray bursts gravitationally lensed by galaxy clusters
Dan Ryczanowski, Benjamin P. Jones, Benjamin P. Gompertz +1
Discoveries of gamma-ray bursts (GRBs) have become commonplace in recent decades, totalling unique detections across various missions. However, there have been…
A Salpeter IMF and an NFW halo: Disentangling the dark and stellar mass of an elliptical galaxy through precise lens modelling of a double-source-plane system
Tian Li, Thomas E. Collett, Coleman M. Krawczyk +7
We present a strong lensing analysis of the double source plane lens J0946+1006 (colloquially "Jackpot" lens) to measure the inner dark matter density profile, the stellar-to-halo…
The impact of ultraviolet suppression on the rates and properties of strongly lensed Type IIn supernovae detected by LSST
Andrés I. Ponte Pérez, Graham P. Smith, Matt Nicholl +4
Upcoming wide-field time-domain surveys, such as the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) are expected to discover up to two orders of magnitude more…
A follow-up strategy enabling discovery of electromagnetic counterparts to highly-magnified gravitationally-lensed gravitational waves
Dan Ryczanowski, Jeff Cooke, James Freeburn +6
Making an unambiguous detection of lensed gravitational waves is challenging with current generation detectors due to large uncertainties in sky localisations and other inferred pa…
Multi-messenger Gravitational Lensing
Graham P. Smith, Tessa Baker, Simon Birrer +38
We introduce the rapidly emerging field of multi-messenger gravitational lensing - the discovery and science of gravitationally lensed phenomena in the distant universe through the…
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…
Challenges and Opportunities for time-delay cosmography with multi-messenger gravitational lensing
Simon Birrer, Graham P. Smith, Anowar J. Shajib +2
Strong gravitational lensing of variable sources, such as quasars or supernovae, can be used to constrain cosmological parameters through a technique known as "time-delay cosmograp…
Rubin ToO 2024: Envisioning the Vera C. Rubin Observatory LSST Target of Opportunity program
Igor Andreoni, Raffaella Margutti, John Banovetz +86
The Legacy Survey of Space and Time (LSST) at Vera C. Rubin Observatory is planned to begin in the Fall of 2025. The LSST survey cadence has been designed via a community-driven pr…
Find the haystacks, then look for needles: The rate of strongly lensed transients in galaxy-galaxy strong gravitational lenses
Ana Sainz de Murieta, Thomas E. Collett, Mark R. Magee +5
The time delay between appearances of multiple images of a gravitationally lensed supernova (glSN) is sensitive to the Hubble constant, . As well as time delays, a lensed host…
Towards discovery of gravitationally lensed explosive transients: the brightest galaxies in massive galaxy clusters from Planck-SZ2
Joshua C. Smith, Dan Ryczanowski, Matteo Bianconi +7
We combine the Planck-SZ2 galaxy cluster catalogue with near-infrared photometry of galaxies from the VISTA Hemisphere Survey to identify candidate brightest cluster galaxies (BCGs…
The impact of human expert visual inspection on the discovery of strong gravitational lenses
Karina Rojas, Thomas E. Collett, Daniel Ballard +53
We investigate the ability of human 'expert' classifiers to identify strong gravitational lens candidates in Dark Energy Survey like imaging. We recruited a total of 55 people that…
Enabling discovery of gravitationally lensed explosive transients: a new method to build an all-sky watch-list of groups and clusters of galaxies
Dan Ryczanowski, Graham P. Smith, Matteo Bianconi +4
Cross-referencing a watchlist of galaxy groups and clusters with transient detections from real-time streams of wide-field survey data is a promising method for discovering gravita…
On the gravitational lensing interpretation of three gravitational wave detections in the mass gap by LIGO and Virgo
Matteo Bianconi, Graham P. Smith, Matt Nicholl +7
We search for gravitational wave (GW) events from LIGO-Virgo's third run that may have been affected by gravitational lensing. Gravitational lensing delays the arrival of GWs, and…
Discovering gravitationally lensed gravitational waves: predicted rates, candidate selection, and localization with the Vera Rubin Observatory
Graham P. Smith, Andrew Robertson, Guillaume Mahler +7
Secure confirmation that a gravitational wave (GW) has been gravitationally lensed would bring together these two pillars of General Relativity for the first time. This breakthroug…
Strong Lensing Science Collaboration input to the on-sky commissioning of the Vera Rubin Observatory
Graham P. Smith, Timo Anguita, Simon Birrer +10
We present the Strong Lensing Science Collaboration's (SLSC) recommended observing targets for the science verification and science validation phases of commissioning. Our recommen…
On building a cluster watch-list for identifying strongly lensed supernovae, gravitational waves and kilonovae
Dan Ryczanowski, Graham P. Smith, Matteo Bianconi +3
Motivated by discovering strongly-lensed supernovae, gravitational waves, and kilonovae in the 2020s, we investigate whether to build a watch-list of clusters based on observed clu…
What does strong gravitational lensing? The mass and redshift distribution of high-magnification lenses
Andrew Robertson, Graham P. Smith, Richard Massey +4
Many distant objects can only be detected, or become more scientifically valuable, if they have been highly magnified by strong gravitational lensing. We use EAGLE and BAHAMAS, two…
