Defining Pathway Assembly and Exploring its Applications

Kavli Affiliate: Stuart Marshall | First 5 Authors: Alastair Murray, Stuart Marshall, Leroy Cronin, , | Summary: How do we estimate the probability of an abundant objects’ formation, with minimal context or assumption about is origin? To explore this we have previously introduced the concept of pathway assembly (as pathway complexity), in a graph based […]

Red nuggets grow inside-out: evidence from gravitational lensing

Kavli Affiliate: Philip Marshall | First 5 Authors: Lindsay Oldham, Matt Auger, Chris Fassnacht, Tommaso Treu, Brendon J. Brewer | Summary: We present a new sample of strong gravitational lens systems where both the foreground lenses and background sources are early-type galaxies. Using imaging from HST/ACS and Keck/NIRC2, we model the surface brightness distributions and […]

Systematic Study of Gamma-ray bright Blazars with Optical Polarization and Gamma-ray Variability

Kavli Affiliate: Grzegorz M. Madejski | First 5 Authors: Ryosuke Itoh, Krzysztof Nalewajko, Yasushi Fukazawa, Makoto Uemura, Yasuyuki T. Tanaka | Summary: Blazars are highly variable active galactic nuclei which emit radiation at all wavelengths from radio to gamma-rays. Polarized radiation from blazars is one key piece of evidence for synchrotron radiation at low energies […]
