ALMA Cycle 8 2021 Supplemental Call Pre-Announcement

Published: 24 Aug 2021

The Cycle 8 Supplemental Call for Proposals is anticipated to open at 15:00 UT on September 8 with a proposal deadline of 15:00 UT on October 6. ALMA expects to allocate a minimum of 1500 h of observing time on the ACA in the Supplemental Call. Proposals are encouraged between a LST range of 20 to 10 h. Preliminary information is currently available. Complete details of the Supplemental Call will be posted on the ALMA Science Portal on September 8.

Update on the Amplitude Calibration Issue Affecting some ALMA Data

Published: 24 Aug 2021

ALMA has begun work on correcting some Cycle 7 interferometric datasets for a visibility amplitude calibration error that affects fields containing strong astronomical emission -details were described in this previous announcement. For all affected datasets with a >10% flux scale offset that have yet to be delivered, including those that will be observed in the remainder of Cycle 7 and in Cycle 8 2021, ALMA will apply a renormalization correction during data processing to correctly scale the amplitude calibration before being sent to PIs. For affected datasets with flux scale offsets >2% but <10%, ALMA will provide renormalized data on request from the PI as needed. For affected data in the ALMA Archive, an investigation is underway and plans will be described in a future announcement.

ESO Fellowship Programme

Published: 05 Aug 2021

ESO's prestigious postdoctoral fellowship programme in both Garching (Germany) and Santiago (Chile) offers outstanding early-career scientists the opportunity to further develop their independent research programmes. From exoplanets to cosmology, observational, theoretical and fundamental astrophysics, these are all areas where ESO Fellows can benefit from a highly dynamic scientific environment, at some of the most advanced ground-based telescopes in the world. Do watch ESOCast 165 to hear what current ESO fellows have to say about the fellowship programme or watch the virtual tour to ESO's premises from last year where young scientists could ask question about the fellowship programme.

Third Release of the PESSTO Multi-Epoch Catalogue

Published: 04 Aug 2021

A new version of the PESSTO Multi-Epoch Photometric Catalogue provides photometric lightcurve coverage for the Public European Southern Observatory Spectroscopic Survey of Transient Objects (PESSTO) targets for which follow-up lightcurves have been completed.This catalogue complements and completes the DR4 release announced in March 2021.

Third and Final Data Release of the Large Early Galaxy Census (LEGA-C) Spectroscopic Public Survey Published

Published: 29 Jul 2021

The third and final data release of the Large Early Galaxy Astrophysics Census (LEGA-C, ESO programmes 194.A-2005, 1100.A-0949) is now available. The LEGA-C public spectroscopic survey targets the 1.5 deg2 of the COSMOS field (RA=10hr, Dec=+2 deg) with the VLT VIMOS multi-object spectrograph from December 2014 to May 2018.

First Data Release of the PHANGS-MUSE Large Programme

Published: 23 Jul 2021

The PHANGS-MUSE project is an ESO Large Programme (PROGRAM ID: 1100.B-0651, PI: E. Schinnerer) which (including exposures from archival programs: 094.B-0321, 094.C-0623, 095.C-0473, 097.B-0640, 098.B-0551, 099.B-0242, 0100.B-0116) maps with MUSE 19 star forming spiral galaxies. This release provides combined mosaics of their central star-forming disk obtained by combining 5 to 15 MUSE pointings for each galaxy. In addition derived maps of emission line fluxes and kinematics as well as stellar kinematics are also included as ancillary files.

ALMA Cycle 7 Science Observations Status Update

Published: 16 Jul 2021

Cycle 7 PI science observations have been continuing, although with some significant interruption due to snowstorms at the end of May and in mid-June. Combined with pandemic conditions affecting maximum staffing levels at the site, this led to a delay in reaching the 12-m Array C43-7 configuration (completed on 12 July). Unfortunately, the delay has an impact on the configuration schedule for the remainder of Cycle 7.

Registration Open for "The ALMA 2030 Vision: A Next Generation of Front-End Receivers"

Published: 16 Jul 2021

Registrations are open for "The ALMA 2030 Vision: A next generation of front-end receivers" workshop. Abstracts can be submitted here until July 16, 2021. Potential participants can inquire with the organization about late submission of abstracts, via ALMA_FED_2021@eso.org. This workshop will be held online, in the week of September 27-30, 2021.

Amplitude Calibration Issue Affecting some ALMA Data

Published: 16 Jul 2021

A visibility amplitude calibration error that affects fields containing strong line emission has been discovered in ALMA interferometer observations up to and including Cycle 7. This calibration scaling error originates in the combined effect of correlator spectral normalization and Tsys calibration and affects both 12-m Array and Atacama Compact Array observations. The effect of this amplitude scaling error is most notable for observations of strong, relatively narrow spectral lines, typically related to Galactic ISM and Galactic star formation (e.g., molecular lines, masers, etc.).
