Jes Jørgensen

We are involved in a number of projects. On these pages you can find some pages dedicated to specific projects for which data and/or tools are being made publicly available. For more about M.Sc. thesis projects in the group visit this page...


Herschel/DIGIT observations of embedded low-mass protostars

We are involved in the Herschel open time key program, “Dust, Ice and Gas in Time (DIGIT)” (Neal Evans, PI). Jes Jørgensen is leading the effort focusing on the properties of embedded protostars.

Members of that group can access the team wiki.

SMA observations of the low-mass protostellar binary IRAS 16293-2422

Over the years we have been involved in a number of studies of low-mass protostars using (sub)millimeter interferometry - including two larger surveys. One of these is a comprehensive survey of the line and continuum emission from the protostellar binary IRAS 16293-2422.

Data and papers from this survey are available on a dedicated page.

Initiative for Danish Far-Infrared and Submillimeter Astronomy (DFSA)

Together with Thomas Greve (DARK Cosmology Center) I ran an initiative for Danish Far-Infrared and Submillimeter Astronomy (DFSA) funded by the Instrumenter for Danish Astrophysics (IDA) in 2010-2011. The aim of this was to stimulate interest in far-IR and submillimetre astronomy in Denmark - in particular, with involvement in the Atacama Large Millimeter Array and the Herschel Space Observatory in mind. Besides serving as “local” expertise for questions and discussions on far-IR and submillimetre astronomy, we (co-)organized workshops and meetings touching upon these topics.

Adaptable Radiative Transfer Innovations for Submillimeter Telescopes

Submillimeter observations are a key for answering many of the big questions in modern-day astrophysics, such as how stars and planets form, how galaxies evolve, and how material cycles through stars and the interstellar medium. With the upcoming large submillimeter facilities ALMA and Herschel a new window will open to study these questions. One of the challenges will be to keep up with sophisticated analysis tools to prepare observations using these facilities as well as interpret the data coming from them.

Within the ASTRONET first joint call for proposals, "Common Tools for Future Large Submillimeter Facilities", we have been awarded funding for our program, "Adaptable Radiative Transfer Innovations for Submillimeter Telescopes (ARTIST)", to develop a next generation model suite for comprehensive multi-dimensional radiative transfer calculations of the dust and line emission, as well as their polarization, to help interpret observations with these groundbreaking facilities.
