Edge of darkness: The splashback radius as a physical halo boundary The radii and masses of dark matter halos are an essential input for models of galaxy formation, and for the interpretation of numerous observations. These radii are typically defined through an arbitrary overdensity threshold, largely because the density profiles of halos are thought not to have a well-defined edge. In ...

Insights into Supermassive Black Hole Mergers, Stalling and Demographics with Pulsar Timing ArraysGalaxy mergers are a standard aspect of galaxy formation and evolution, and likely all large galaxies contain central supermassive black holes (SMBH). Here I discuss a new bottom-up approach to identifying continuous nanohertz gravitational wave (GW) host galaxies by using massive elliptical galaxies in the 2 Micron All Sky Survey, ...

Network dynamics of fixed and flexible passenger transport under operational and behavioural uncertaintyThe metropolitan passenger transport landscape is shifting due to a combination of technological and social developments which enable both service providers and service users to become increasingly adaptive. Service providers can manage their resources to better cater for prevailing demand patterns, while service users can adjust their behaviour in response ...

Nanoscale Excitations in Space and TimeThe static and dynamic properties of matter depend largely on its inherent heterogeneity in the mass, charge, and spin distributions. Excitations within and coupling of matter to its environment would be expected to exhibit spatial and temporal dependences. Because matter is assembled from individual atoms and molecules, a viable approach ...
Neutrinos are the most numerous matter particles in the universe, but the least understood. The peculiar properties of neutrinos suggest connections to many of the big mysteries of particle physics, including the possibility that the matter we are made of originated from neutrinos. Today a host of new experiments are ...

ELECTRONICS AND OPTO-ELECTRONICS WITH TWO-DIMENSIONAL ATOMIC CRYSTALSTwo-dimensional (2D) atomic crystals are recently discovered materials that are only atoms thick, and yet can span laterally over millimeters. The diverse family of such materials includes graphene: a semimetal with massless relativistic charge carriers, and monolayer transition metal dichalcogenides (TMDCs), such as molybdenum disulfide (MoS2): direct band gap semiconductors ...
Otherlab is a research and development firm focusing on renewable and clean energy, robotics, automation, digital fabrication, adaptive textiles, advanced manufacturing, and computational design tools. Similar to an accelerator/incubator, but with internally developed ideas, we nurture projects through the initial R&D phase, to forming entities within Otherlab, and eventually fundraising ...

Cooperative Interactions as a Route to High Temperature SuperconductivityHigh-temperature superconductivity in copper and iron based materials, with critical temperature well above what was anticipated by the Bardeen-Copper-Schrieffer theory, remains a major unsolved physics problem today. The challange of this problem is symbolized by a complex phase diagram that consists of intertwined states with unusual properties in addition to ...
Anthropologist Nina Jablonski will explore the troubling lack of evolution, diversity, and race education in American classrooms, and how this absence manifests as an adult population ill-equipped to tackle thornier issues at the intersection of science and identity. Jablonski's research indicates that children do grasp these complex concepts, offering a glimmer of hope that effectively leveraging early ...
