SLSim: a strong lensing population simulation package
Narayan Khadka, Simon Birrer, Henry Best +45
Gravitational lensing offers unique insights into cosmology by bending light around massive objects. Strong gravitational lensing, in particular, produces magnified and often multi…
A halo model approach for mock catalogs of time-variable strong gravitational lenses
Katsuya T. Abe, Masamune Oguri, Simon Birrer +5
Time delays in both galaxy- and cluster-scale strong gravitational lenses have recently attracted a lot of attention in the context of the Hubble tension. Future wide-field cadence…
Multi-band observation of lensed gravitational waves as a probe of small-mass dark matter halos
Katsuya T. Abe, Shun Arai, Ryoto Inui +3
The gravitational lensing effect of gravitational waves (GWs) has been extensively discussed as a probe of small-mass dark matter halos, which can provide missing information about…
Identification of 40 gravitationally magnified stars in a galaxy at redshift of 0.725
Yoshinobu Fudamoto, Fengwu Sun, Jose M. Diego +44
Strong gravitational magnifications enable to detect faint background sources, resolve their internal structures, and even identify individual stars in distant galaxies. Highly mag…
