Jordan Goodman is a professor and the former Chair of Physics Department at the University of Maryland. His area of research, Particle Astrophysics, studies cosmic radiation to better understand the properties of elementary particles and the processes in space that produce these particles. This field blends elements of high energy physics and astrophysics.

Starting with his Ph.D. work, which showed evidence for an abundance of heavy elements such as iron in high energy cosmic rays, he has worked to understand the nature of cosmic rays which hit the earth. Recently, his work has concentrated on two experimental efforts-- Milagro and IceCube.
 

Milagro

Milagro is located in the mountains of New Mexico and is designed to study high energy gamma-rays from space. Dr. Goodman is the scientific co-spokesman for Milagro.

 

 

 

 

 

 

Milagro is the first gamma ray detector capable of continuously monitoring the entire overhead sky at energies below 1 TeV.The energy threshold of Milagro is an order of magnitude lower than any other all-sky instrument operating in the VHE regime.Milagro is the ideal instrument to study the transient and variable sources of VHE gamma rays in the Universe and to discover new phenomena.

 The Milagro detector is used to:

Search for gamma-ray bursts emitting TeV gamma rays.

Search for nearby active galactic nuclei (AGN).

Search the Northern Hemisphere sky for sources of TeV gamma rays. 

Search for primordial black holes (PBH). 

Observe galactic point-like and diffuse sources  

Study the properties of the solar magnetic field.

IceCube- IceCube is a one-cubic-kilometer international high-energy neutrino observatory being built and installed in the clear deep ice below the South Pole Station. IceCube will open unexplored bands for astronomy, including the PeV (10^15 eV) energy region, where the Universe is opaque to high energy gamma rays originating from beyond the edge of our own galaxy, and where cosmic rays do not carry directional information because of their deflection by magnetic fields. The instrument may, for example, answer the question of whether the fascinating multi-TeV photons originating in the Crab supernova remnant and near the supermassive black holes of active galaxies are of hadronic or electromagnetic origin. IceCube will provide a totally novel viewpoint on the multi-messenger astronomy of gamma ray bursts, which have been identified as a possible source of the highest energy particles in nature.

Dr. Goodman is a fellow of the American Physical Society, a 1999/2000 University of Maryland Distinguished Scholar Teacher and a winner of the USM Regents award for excellence in teaching and a Kirwan Award winner for teaching excellence. He is also the 2002 Richtmyer Award winner from the American Association of Physics teachers. His CV can be found here.
