Impact of COVID-19 on ESO Proposal Submission Deadline

Published: 20 Mar 2020

Given ongoing developments related to the COVID-19 pandemic, ESO is doing its best to guarantee that the proposal submission and review processes remain optimal within the restrictions imposed by this crisis. Since containment measures deployed in some of ESO’s Member States have disrupted scientific activities in those countries, the proposal submission deadline has been postponed from 26 March to 23 April 12:00 CEST. ESO will continue to follow developments closely and may provide additional updates regarding Phase 1 in the next weeks.

ALMA Cycle 8 Call for Proposals Deadline Delayed Due to COVID-19

Published: 19 Mar 2020

The ALMA Director, on behalf of the Joint ALMA Observatory and the partner organisations in East Asia, Europe, and North America, is pleased to announce that the ALMA Cycle 8 Call for Proposals for scientific observations opened on March 17. Users of any nationality or affiliation are invited to submit proposals. Please note that, due to the COVID-19 pandemic, the original deadline of 15:00 UT on 15 April 2020 has now been delayed to no earlier than 15:00 UT on 19 May 2020. As ALMA continues to monitor the conditions worldwide, it will assess the feasibility of this deadline and provide additional updates to the community as needed. The next update to the community will be provided no later than 21 April 2020 on the status of the call and the support for the scientific community.

Impact of COVID-19 on ESO Operations

Published: 19 Mar 2020

In response to the rapidly evolving COVID-19 pandemic around the world ESO has been following the measures adopted by governments in Germany and Chile and closely observing the situation in other countries. Our highest priority remains the safety and wellbeing of all staff and visitors at ESO’s sites. To minimise the risk of infection the presence of staff has been significantly reduced at the observatories over the past week leading to a number of restrictions to the ongoing science operation. Over the coming weekend, the staff at the observatories will be further reduced to the minimal teams required to ensure the safety of the facilities and the remaining people on site.

As a consequence science operation will cease at all sites.

ALMA Cycle 7 Observations Suspended due to COVID-19

Published: 18 Mar 2020

Due to the COVID-19 outbreak that has spread to Chile, the ALMA Director has made the decision to suspend science operations with ALMA, effective immediately. This decision has been taken to protect the safety of ALMA staff, many of whom travel long distances by bus and by plane to reach the remote ALMA site in the Atacama Desert in northern Chile.

ALMA Cycle 8 Call for Proposals: Dual-Anonymous Proposal Review Process

Published: 16 Mar 2020

ALMA is strongly committed to ensure that the proposal review process is as fair and impartial as possible. Analysis of the proposal rankings in previous cycles has identified systematics that may signify the presence of biases in the review process (see Systematics in the ALMA Proposal Review Rankings). In an effort to reduce biases as much as possible, ALMA will use a dual-anonymous proposal review process starting in Cycle 8.
