Stars are among the most numerous objects in the Cosmos, and are the primary objects that make the bulk of larger structures we observe. They are born together, and consequently evolve together, often interacting with a close companion over the course of their lives, or interacting dynamically with many other stars in the dense stellar environments in which they are found. These interactions have profound influence on the long term evolution of stars. In CIERA, we consider numerical and theoretical models of stellar interactions and use them to understand and explain observations of stars across the Milky Way, and in dense stellar systems.

Research at CIERA

 

The centers of galaxies are complex environments whose properties are a result of the interactions between the massive black holes that reside there, vast clouds of gas, and dense populations of stars and stellar remnants.

Professor Rasio’s group studies numerical models of dense stellar environments such as nuclear star clusters.

Professor Larson’s group studies the interactions of single stars with massive black holes, a prospective LISA gravitational wave source class known as an EMRI (“extreme mass ratio inspiral”).

Professor Zadeh is an observer who studies stellar populations and physical processes in the Milky Way nucleus using observations across the electromagnetic spectrum.

Opportunities

CIERA Postdoctoral Fellowship Positions in Astronomy & Astrophysics

Deadline: 11:59pm, November 22, 2021

The Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA) at Northwestern University invites applications for CIERA Postdoctoral Fellowships. CIERA Fellows have the opportunity to pursue an independent research program and benefit from a diverse and dynamic intellectual environment.

Postdoctoral Associate Positions in Observational Astronomy & Astrophysics

Deadline: 11:59pm, November 22, 2021

Northwestern University expects to offer postdoctoral associate positions in observational astronomy and astrophysics starting in fall 2022. These positions will be part of the Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA) at Northwestern. Successful applicants will benefit from interaction with a broad interdisciplinary group of researchers and will be immersed in a diverse and dynamic intellectual environment.

DSFP Postdoctoral Fellow

Deadline: 11:59pm, December 16, 2021

We invite applications for a postdoctoral scholar to join Northwestern’s Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA) and the leadership of the LSSTC Data Science Fellowship Program (DSFP). The DSFP Postdoctoral Fellow will divide their time equally between conducting an independent research program in data science in astronomy/astrophysics, while continuing the development and growth of the DSFP.
