The Australian, Chinese, European, Indian, and North American pulsar timing array (PTA) collaborations recently reported, at varying levels, evidence for the presence of a nanohertz gravitational-wave background (GWB). Given that each PTA made differ... Read More about Comparing Recent Pulsar Timing Array Results on the Nanohertz Stochastic Gravitational-wave Background.

We investigate the formation of dense stellar clumps in a suite of high-resolution cosmological zoom-in simulations of a massive, star-forming galaxy at z ∼ 2 under the presence of strong quasar winds. Our simulations include multiphase ISM physics f... Read More about Dense stellar clump formation driven by strong quasar winds in the FIRE cosmological hydrodynamic simulations.

The attenuation of radiation due to dust depends on the composition and optical properties of the dust grains. This is fundamental to determine the impact of radiation on chemical evolution. In this chapter, we discuss how we can compute grain proper... Read More about The interplay between dust and radiation.
