Curriculum Vitae:

Paul Goldsmith
Group Supervisor

Dr. Paul Goldsmith is the Group Supervisor for 3266 – Structure of the Universe. His recent work has focused on determining time scales of processes associated with the formation of molecular clouds and young stars. This has included use of atomic hydrogen in molecular clouds as a tracer of their evolution and history. Goldsmith has also worked on determining the conditions for formation of massive stars by using molecular line and dust continuum emission. He has also been using specific tracers of chemistry in the interstellar medium to assess the impact of star formation on surrounding molecular cloud material via heating of dust, shock waves, and other processes.

Research Interests

Dr. Goldsmith's areas of interest in astronomy include unraveling the structure of molecular clouds and understanding how star formation occurs within them. This has led to developing techniques for probing the densities, temperatures, and other physical conditions in these regions. In addition to carrying out ground-based and airborne observations, he was a co-investigator with the Submillimeter Wave Astronomy Satellite (SWAS), studying water, atomic carbon, molecular oxygen, and carbon monoxide. Goldsmith was the PI on the Herschel Oxygen Project, which has made the first multi-transition detection of this species in interstellar space. Goldsmith is working with colleagues at JPL interpreting data from the fine structure line of ionized carbon. He has been involved in modeling the collisional excitation and radiative transfer of the 158 μm [CII] line. The first extensive velocity - resolved spectra of this important coolant of interstellar clouds have been obtained with the HIFI instrument on Herschel. Observations using the GREAT instrument on SOFIA are continuing. He is also pursuing large-scale surveys of the structure lines with GUSTO and ASTHROS balloon missions. Goldsmith has an ongoing interest in astronomical instrumentation, especially high-sensitivity systems at centimeter to submillimeter wavelengths. He has also been actively involved in development of focal plane array receivers for radio and submillimeter telescopes. He has worked on the optical design of multiobject spectrometer systems for the CCAT telescope and has participated in a number of proposals for array receivers for submillimeter fine structure lines on balloons and SOFIA.
