The influence of the matter along the line of sight and in the lens environment on the strong gravitational lensing
M. Jaroszynski, Z. Kostrzewa-Rutkowska
We investigate the influence of the matter along the line of sight and in the lens environment on the image configurations, relative time delays, and the resulting models of strong…
A plausible (overlooked) super-luminous supernova in the SDSS Stripe 82 data
Zuzanna Kostrzewa-Rutkowska, Szymon Kozlowski, Lukasz Wyrzykowski +4
We present the discovery of a plausible super-luminous supernova (SLSN), found in the archival data of Sloan Digital Sky Survey (SDSS) Stripe 82, called PSN 000123+000504. The supe…
On rates of supernovae strongly lensed by galactic haloes in Millennium Simulation
Zuzanna Kostrzewa-Rutkowska, Lukasz Wyrzykowski, Michal Jaroszynski
We make use of publicly available results from N-body Millennium Simulation to create mock samples of lensed supernovae type Ia and core-collapse. Simulating galaxy-galaxy lensing…
Background, foreground and nearby matter influence on strong gravitational lenses
M. Jaroszynski, Z. Kostrzewa-Rutkowska
We investigate strong lensing by non-singular finite isothermal ellipsoids taking into account the influence of the matter along the line of sight and in the close lens vicinity. W…
