Welcome on the Herschel Database in Marseille. HeDaM is dedicated to hosting the data of some of ESA's Herschel space observatory key programmes.
HeDaM is operated by the Centre de donnéeS Astrophysiques de Marseille (CeSAM) of the Laboratoire d'Astrophysique de Marseille (Aix-Marseille University / CNRS).
The “Herschel Extragalactic Legacy Project”
The Herschel Extragalactic Legacy Project (HELP) is a follow up project aiming to capitalise on Herschel big extra-galactic projects by collating and homogenising data at other wavelengths as well a spectroscopic redshifts, extracting far infrared fluxes using prior information, and performing SED fitting to provide physical parameters.
The public HELP data (catalogues and images) are available on HeDaM

The “Herschel Multi-tiered Extragalactic Survey”
The Herschel Multi-tiered Extragalactic Survey (HerMES) is an astronomical project to study the evolution of galaxies in the distant universe. It is the largest project on Herschel space observatory (900 guaranteed hours).
The public HerMES data (catalogues and images) are available on HeDaM

The “Herschel Reference Survey”
The Herschel Reference Survey (HRS) is a guaranteed time Herschel key project and will be a benchmark study of dust in the nearby universe. The survey will complement a number of other Herschel key projects including large cosmological surveys that trace dust in the distant universe.
HeDaM holds the result data of HRS project as well as some ancillary data used in HRS publications.

The “Very Nearby Galaxy Survey”
The Very Nearby Galaxy Survey (VNGS) is a guaranteed time Herschel key project aiming at measuring the emission spectrum from dust as well as important cooling lines from the gaseous interstellar medium in a sample of 13 very nearby galaxies.
The public data of VNGS is published through the HeDaM Site.

The “GOODS-Herschel Survey”
The GOODS-Herschel survey is an open time Herschel key programme of more than 360 hours of observation with the instruments SPIRE and PACS from 100 µm to 500 µm on the two fields of the Great Observatories Origins Deep Survey (GOODS).
The public data of GOODS-Herschel is published through the HeDaM site.

Herschel is an ESA space observatory with science instruments provided by European-led Principal Investigator consortia and with important participation from NASA.
