“Worst-Case” Micro-Lensing in the Identification and Modeling of Lensed Quasars

Kavli Affiliate: Paul Schechter | First 5 Authors: Luke Weisenbach, Paul Schechter, Sahil Pontula, , | Summary: Although micro-lensing of macro-lensed quasars and supernovae provides unique opportunities for several kinds of investigations, it can add unwanted and sometimes substantial noise. While micro-lensing flux anomalies may be safely ignored for some observations, they severely limit others. […]

Revisiting CMB constraints on dark matter annihilation

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Hiromasa Nakatsuka, Kazunori Nakayama, Toyokazu Sekiguchi, | Summary: The precision measurements of the cosmic microwave background power spectrum put a strong constraint on the dark matter annihilation cross section since the electromagnetic energy injection by the dark matter annihilation affects the ionization history of the […]
