Tracking Australian VLT publications

As part of AAL's role in assisting the Dept of Industry, Science and Resources in managing Australia's Strategic Partnership with ESO, we monitor not just the proposal submissions and allocations but also any refereed publications involving Australian-based astronomers that use data from the Very Large Telescope (VLT) and...

Measuring reliable stellar abundances towards crowded regions using MUSE

With the rapid development of stellar spectroscopy in the past decade, many stellar spectroscopic surveys, for example LAMOST, GALAH and APOGEE, combined with the astrometric information of Gaia have played a pivotal role in explaining the chemo-dynamic evolution of the Milky Way.

Australian-based astronomers to take a deep dive into the cosmos with time awarded on one of ESO’s most powerful instruments

In lieu of an AAL ESO Blog post this month, we encourage our community to take a look at the exciting science to be enabled by the recent awarding of ESO Large Programme status to not one, but two Australian-led projects using MUSE, the most-oversubscribed instrument on the...

A new sample of gravitational lenses followed up with the VLT and Keck

Gravitational lenses are powerful cosmic "magnifying glasses" that can be used to explore a broad range of astrophysical phenomena in both the background lensed galaxy (the "source") and the foreground lens (the "deflector").

MAVIS team outside

MAVIS gets busy!

The Australian-led international consortium building the MAVIS (Multi-conjugate adaptive optics Assisted Visible Imager and Spectrograph) instrument for the European Southern Observatory (ESO) gathered together recently for a project ‘Busy Week’ - five days of intensive activity and interaction to progress on key aspects of the project.

Removing the second cosmological lithium problem with a shot of ESPRESSO

Lithium is the heaviest element produced in Big Bang nucleosynthesis (BBN). As such, it is a unique element that can be used to study the conditions of the Big Bang. Standard BBN theory produced mostly hydrogen and helium, with trace amounts of lithium - about 1 in 10...

Going global with fast radio bursts, the VLT, and ASKAP

Fast Radio Bursts (FRBs) are now showing their potential as a cosmological tool. The bursts were initially discovered with single dish radio telescopes like Murriyang (the 64-m Parkes Radio Telescope), as dispersed pulses of radio emission.

Probing the Broad Line Region of Active Galactic Nuclei with SOFI at La Silla

Type 1 active galactic nuclei (AGN) show broad spectral lines, with characteristic velocities of several thousand kilometres per second. These are thought to come from a region (BLR – the broad-line region) of gas clouds close to the central black hole, but how these are distributed and orbit...

A FLASH combination: ASKAP and MUSE sniff out gas around galaxies

The timescales in which star-forming galaxies deplete their gas is found to be short relative to the age of the Universe. This points to the conclusion that galaxies must have a way to replenish their gas reservoirs and indeed, early cosmological simulations reveal cold gas being channeled along...
