Results of the 2021 Paranal Service Mode User Satisfaction Survey

Published: 02 Dec 2021

The User Support Department again extends its thanks to all those Principal Investigators and their Phase 2 delegates who filled this year's online Paranal Service Mode User Satisfaction Survey. A total of 248 responses were received from the targeted campaign. As in the past, where possible, respondents who provided detailed comments have been contacted via e-mail. A summary report based on this latest User Satisfaction Survey is now available.

First Data Release of the ARO MASCOT Survey

Published: 01 Dec 2021

MASCOT (MaNGA-ARO Survey of CO Targets) is an ESO Public Spectroscopic Survey conducted with the 12m telescope at the Arizona Radio Observatory (ARO). It provides the community with CO(1-0) measurements of 187 galaxies at 0.03 < z < 0.1 and stellar masses of > 109.5 M, all selected from the SDSS-MaNGA survey. Through the SDSS-MaNGA data releases, all MASCOT targets have accompanying optical IFU observations and well-constrained (spatially resolved) quantities like stellar masses, star formation rates and metallicities. The first data release of the MASCOT Survey for is now available to the community through the Supplementary Material of the Data Release Paper as well as on the MASCOT website.

New Talk Series: ALMA Recounts of Cosmic Conundrums

Published: 26 Nov 2021

The European ARC network is launching the new virtual talk series "ALMA recounts of Cosmic Conundrums". In every talk of this series a major astronomical question is discussed. The invited speaker will describe the context of the question and then focuses on the ALMA contribution to the field, past and future. The aim of the series is to highlight the unparalleled contribution of ALMA to the broader astronomical landscape and to provide an outlook towards the future.

New Gaia-ESO Radial Velocity Catalogue Released (DR4.1)

Published: 25 Oct 2021

Gaia-ESO is a Public Spectroscopic Survey carried out with GIRAFFE and UVES on the VLT between 2012 and 2018. The survey targeted more than 100,000 stars, with 115,000 actually observed by the end of the survey. These stars are selected across all major components of the Milky Way, from halo to star-forming regions, with the goal of providing a homogeneous overview of their kinematics and elemental abundance distributions.

VVVX DR1.1 Published: Releasing the Entire Ks Time Series

Published: 20 Oct 2021

The VISTA Cycle 2 ESO Public Survey project -VVV eXtended- PI D. Minniti, P. Lucas, is carried out with VIRCAM on VISTA in the JHKs filters and covers a total of ~1540 deg2 of the southern Galactic plane. The VVVX DR1.1 complements DR1 by mainly providing i) the missing Ks time series and ii) the source lists generated from the pawprints published in DR1, which were observed between July 2016 and March 2018. The released data total about 9 TB. Science products generated from observations in the time interval from April 2018 to October 2019 are accessible in the already published DR2 release.
