[30.03] The EVLA and the Obscured Universe

M. J Claussen (NRAO), EVLA Science Team

Many interesting phenomena, including star formation and accretion onto massive black holes, generally occur behind dense screens of gas and dust which make optical and even infrared observations difficult or impossible. Radio waves, by contrast, are not easily obscured, and hence can be used to look directly through these dust screens. The Expanded Very Large Array (EVLA) will be an astronomical research instrument of unprecedented power and flexibility in the meter-to-millimeter wavelength bands. Sensitivity and resolution will be enhanced by a factor of 10 over the VLA, enabling many new studies of the Obscured Universe. Examples of projects made possible by the EVLA include probing the depths of the atmospheres of the giant planets, measuring ambipolar diffusion and the proper motions of thermal jets in young stellar objects, imaging the densest regions of nearby starburst galaxies, and conducting unbiased searches for quasar absorption lines.

NRAO is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc.
