New Band-Merged Source Catalog Released by the VVV Survey

Published: 09 Oct 2020

A new version of the VVV VISTA Public Survey source catalog is now available from the ESO Archive. The imaging data in the ZYJHKs bands from which the source catalogue is extracted are acquired under ESO programme 179.B-2002 before the 26th of September 2015.  

APEX-LABOCA Flux Map of M83 Released

Published: 08 Oct 2020

A new data release is available that includes a flux map at 870 μm for the galaxy M83 (NGC 5236). It is obtained from the combination of the observations taken with the Large APEX Bolometer Camera (LABOCA) at the Atacama Pathfinder Experiment (APEX), under the ESO programme id 081.C-0827(A), PI A. Lundgren, between 2008-06-19 and 2008-06-30.

Joint First and Second Data Releases of the X-SHOOTER Spectral Library (XSL)

Published: 06 Oct 2020

The X-SHOOTER Spectral Library project (XSL) aims to build a new, moderate-resolution stellar spectral library for use in stellar population modelling. Once completed the XSL will represent a significant improvement on current empirical stellar spectral libraries in terms of stellar parameters and wavelength coverage. The survey was conducted in two phases: a two-semester pilot survey (084.B-0869 and 085.B-0751) followed up by a Large Programme (189.B-0925), PI S.C Trager. The entire survey delivers spectra of a total of nearly 700 unique stars. The joint science spectra products from the first and second XSL data releases are now available to the community via the ESO archive.

2021 ESO Studentships

Published: 02 Oct 2020

The ESO research studentship programme provides an outstanding opportunity for PhD students to experience the exciting scientific environment at one of the world's leading observatories. ESO's studentship positions are open to students enrolled in a university PhD programme in astronomy or related fields. Students accepted into the programme work on their doctoral project under the formal supervision of their home university, but they come to ESO to work and study under the co-supervision of an ESO staff astronomer for a period of between one and two years.

ALMA Starts the Process of Recovering the Telescope Array

Published: 01 Oct 2020

For six months, almost the whole ALMA site has been shut down with no power, water treatment, or running water. Only a single piece of key equipment, the hydrogen maser, is still powered and checked daily as one of the tasks of the ALMA Caretaker Teams, the teams who have ensured the safety and security of the ALMA Observatory through the shutdown. With the improving pandemic situation in Chile, ALMA is now scheduled to begin the long process of recovering the telescope array in the Atacama on October 1st, 2020, starting with preparation of the ALMA Operations Support Facility (OSF) at 2900 metres for the return of staff and contractors.
