Investigating the relation between environment and internal structure of massive elliptical galaxies using strong lensing

,
Abstract: Strong lensing directly probes the internal structure of the lensing galaxies. In this paper, we investigate the relation between the internal structure of massive elliptical galaxies and their environment using a sample of 15 strong…

Analyzing type Ia supernovae near-infrared light curves with Principal Component Analysis

,
Abstract: Type Ia supernovae (SNeIa), the thermonuclear explosions of C/O white dwarf stars in binary systems, are phenomena that remain poorly understood. The complexity of their progenitor systems, explosion physics and intrinsic diversity…

dolphin: A fully automated forward modeling pipeline powered by artificial intelligence for galaxy-scale strong lenses

,
Abstract: Strong gravitational lensing is a powerful tool for probing the internal structure and evolution of galaxies, the nature of dark matter, and the expansion history of the Universe, among many other scientific applications. For almost…
