Overview

The Goddard-IRAM Superconducting 2mm Observer (GISMO) is a bolometer camera for the IRAM 30m telescope. It has been build by Goddard Space Flight Center, in Greenbelt, Maryland under the lead of Johannes Staguhn. GISMO consists of 8x16 pixels with super conducting transition edge sensors (TES). The TES are read out by time domain SQUID multiplexers built at the National Institute for Standards (NIST), in Boulder, Colorado. The nominal bandwidth is 140-162 GHz (FWHM), pixels are spaced by 13.75", the telescope HPBW is 16.7". The sensitivity is about 10 mJy sqrt(sec) per beam (cf. Report on April 2012 observations by Bruni et al. 2012). The field-of-view is 1.8'x3.7'. In the standard observing mode, data are taken while the telescope follows Lissajous curves without switching the secondary. An automated pipeline merges the GISMO data with the telescope data streams to create FITS files which are automatically processed by the reduction software crush to create logs, pointing results, and a first quick view of the data.

The 2mm spectral range provides a unique terrestrial window enabling ground-based observations of the earliest active dusty galaxies in the universe and thereby allowing a better constraint on the star formation rate in these objects.

Call for proposals

GISMO will be offered to the community for the winter semester 2012.

Science Observations

Summer semester 2012 observations will be carried out as pooled observations from a dedicated pool account. G.Bruni will provide login information. Progress of observations can be followed via the pool data base.

Old Runs

April 2012 1st pool run

In September 2011, GISMO had for the 1st time been offered to the community. Two weeks of dedicated GISMO observations have been carried out during April 2012.
