Galaxy mergers are a key driver of galaxy formation and evolution, including the triggering of AGN and star formation to a still unknown degree. We thus investigate the impact of galaxy mergers on star formation and AGN activity using a sample of 3,3

Three-dimensional nucleation and growth of deformation twins in magnesium

Autor: Lee, Sangwon, Pilipchuk, Michael, Yildirim, Can, Greeley, Duncan, Shi, Qianying, Berman, Tracy D., Creuziger, Adam, Rust, Evan, Detlefs, Carsten, Sundararaghavan, Veera, Allison, John E., Bucsek, Ashley

At two-thirds the weight of aluminum, magnesium alloys have the potential to significantly reduce the fuel consumption of transportation vehicles. These advancements depend on our ability to optimize the desirable versus undesirable effects of deform

Semi-Analytic Modeling of Dark Matter Subhalo Encounters with Thin Stellar Streams: Statistical Predictions for GD-1-like Streams in CDM

Autor: Adams, Duncan K., Parikh, Aditya, Slone, Oren, Essig, Rouven, Kaplinghat, Manoj, Price-Whelan, Adrian M.

Stellar streams from disrupted globular clusters are dynamically cold structures that are sensitive to perturbations from dark matter subhalos, allowing them in principle to trace the dark matter substructure in the Milky Way. We model, within the co

A primary target of the \Euclid space mission is to constrain early-universe physics by searching for deviations from a primordial Gaussian random field. A significant detection of primordial non-Gaussianity would rule out the simplest models of cosm

Matched-filtering searches for gravitational-wave signals from compact binary mergers employ template banks which are a collection of modeled waveforms described by unique intrinsic parameters. We present two banks designed for low-latency and archiv
