"Galaxies at Crossroads: Outflows and IMF in the VLT/ELT/ALMA/JWST Era", Brno, Czech Republic, 16-20 September 2024

Published: 31 May 2024

ESO is excited to announce that registration and abstract submission for the ESO conference "Galaxies at Crossroads: Outflows and IMF in the VLT/ELT/ALMA/JWST Era" (GALCROSS) are now open. The conference will be held in Brno, Czech Republic, from 16-20 September 2024. The conference will explore the dynamic processes shaping galaxies, particularly gas outflows, and critically examine important factors like the Initial Mass Function (IMF), ultimately analyzing their reciprocal influence on the chemical enrichment of both stellar and gas components. This event is a unique opportunity to merge theoretical insights and observational breakthroughs, sparked by the latest data from cutting-edge astronomical instruments. The focus is on dissecting the complex interplay between galactic outflows/inflows, the Initial Mass Function (IMF), and the intricate mass-metallicity relationship, all of which are key to understanding the cosmic tapestry of galaxy formation and evolution.

Data Release of the MUSE gAlaxy Groups In COSMOS (MAGIC) Survey Datacubes

Published: 29 Apr 2024

The release of the MUSE gAlaxy Groups In COSMOS (MAGIC) survey (Programmes 094.A-0247, 095.A-0118, 096.A-0596, 097.A-0254, 098.A-0017, 099.A-0246, 0100.A-0607, 0101.A-0282, 0102.A-0327, 0103.A-0563, PI T. Contini) is composed of 18 datacubes, observed with exposure times from 1 to 10 hours, with a median of 4.3 hours, using the wide-field mode, with a spectral sampling of 1.25 Angstroms and a spatial sampling of 0.2 arcsecond. The datacubes cover the wavelength range between 4700 and 9350 Angstroms and have an image quality better than 0.7" FWHM owing to good observing conditions and/or to the use of adaptive optics. The median 3-sigma point-source flux limit of an unresolved emission line reaches 3.6x10-19 erg s-1 cm-2 and the median point source magnitude limit is about 28.5 at 5-sigma in white-light images. The MAGIC survey datacubes target 15 known massive groups and clusters at intermediate redshift (0.3 < z < 0.8), 14 of which being located in the COSMOS field and one in the VVDS field. This dataset is incredibly rich and contains more than one thousand of objects, from stars to high redshift galaxies, as well as extended nebulae.

First ERIS Imaging and IFU Data Become Public

Published: 18 Apr 2024

The  Enhanced Resolution Imager and Spectrograph (ERIS) is a general-use infrared integral field spectrograph and imager that utilises the adaptive optics on the VLT’s UT4. After one year of operation, the proprietary period for the first observations has expired. Both raw and fully processed science data are now publicly available for download via the ESO Archive. The processed data are organised into two data collections, ERIS-NIX and ERIS-SPIFFIER, which contain reduced scientific imaging products and 3D data cubes, respectively. 

European Interferometry Initiative Early Career Prize

Published: 03 Apr 2024

The European Interferometry Initiative (Eii) is an open association of institutes and laboratories willing to collaborate in exploiting and developing long-baseline optical interferometry in optical/infrared astronomy, with the VLT interferometer as its leading facility. To continuously promote excellence in the field, the European Interferometry Initiative is happy to invite nominations for the EII Early Career Prize. The newly created prize will be awarded every two years (even years starting from 2024) by the EII Scientific Council to a young scientist (within four years after their PhD) who distinguished themselves for using optical-infrared long-baseline interferometry.

GRAVITY+ at Higher Spectral Resolution: On-line Workshop, 12-13 September 2024

Published: 01 Apr 2024

GRAVITY has transformed optical interferometry thanks to its unprecedented sensitivity. GRAVITY+ will yet improve VLTI sensitivity by being able to observe targets as faint as K<22 mag. This will allow significant breakthroughs across astrophysical domains as different as AGNs, young stellar objects and exoplanets. Thanks to the sensitivity boost provided by GRAVITY+ this is the time to open VLTI to explore new fundamental physics by installing a new high-resolution grism for GRAVITY+. This workshop is aimed at the wider spectroscopic, and spectro-interferometric community to gather new ideas about how to maximise the scientific exploration of the new GRAVITY high resolution capabilities, and engage with the spectroscopic community with or without interferometric experience.

2024 Users Committee Meeting

Published: 01 Apr 2024

The Users Committee (UC) represents ESO's astronomical community at large and acts as an advisory body to the ESO Director General on matters related to the performance, scientific access, operation and user interfaces to the La Silla Paranal Observatory and ALMA. The annual meeting of the UC is scheduled on 25 and 26 April 2024. During the UC meeting updates from ESO and feedback from the user community are exchanged and openly discussed. Each year one topic is explored in more detail and this year the Special Topic session is dedicated to Large Programmes.

ESO Period 114 Proposal Submission Statistics

Published: 01 Apr 2024

The deadline for proposal submission for Period 114 (1 October 2024 - 31 March 2025) was 21 March 2024: 859 valid proposals were submitted, of which 29 are Large Programmes.  On the VLT, the most demanded ESO instrument was MUSE with a request of 407 nights, followed by ESPRESSO with 249 nights. Probably due to the increasing popularity of ESPRESSO, the pressure on UVES has now reduced to 193 nights. The demand on the still new instrument ERIS keeps increasing, and is now 159 nights. HARPS/NIRPS on the ESO 3.6-metre telescope was the most demanded instrument at La Silla, with a combined request of 239 nights. 

ALMA Cycle 11 Call for Proposals

Published: 01 Apr 2024

The Atacama Large Millimeter and submillimeter Array (ALMA) has opened the Call for Proposals (CfP) for its 11th annual cycle. For this CfP, the Joint ALMA Observatory anticipates having 4300 hours of approved science time on each of the 12-m, 7-m, and the Total Power arrays.  Together, the 7-m Array and Total Power Array form the Atacama Compact Array (ACA), also known as the Morita Array.
